For context, LDAC is one of the few wireless audio codecs stamped Hi-Res by the Japan Audio Society and its encoder is open source since Android 8, so you can see just how long Windows is sleeping on this. I’m excited about the incoming next gen called LC3plus, my next pair is definitely gonna have that.

LDAC is great, but simply stating that the encoder is “open source” is quite misleading (while technically correct). The codec is owned by Sony and heavily licensed. It’s a savvy business move of Sony to make the encoder free to use though, so everyone else can support their standard while charging manufacturers who want to integrate it into their headphones.
If we want a really free and open high quality codec, we should push for opus support via bluetooth
Yes… I made double sure to mention ‘encoder’ between that.
Xiph really won the lossy codec scene with Opus and I transcoded all my junk to that format. Hitting (my personal) transparency on 128k vbr is flat out impressive and it warms my heart that corpos won’t have a reason to collect taxes for basic things like audio codec. However it’s a different story with bluetooth audio codec in which I hope will change.

Same here. I’ve left myself a bit of a safety margin at 144k vbr, but having my whole library at transparent quality AND portable size is very convenient.
Though, now that opus 1.4 is out I feel a bit of anxiety whether i should re-encode everything from flac->opus1.4
Which tool do you use to re-encode everything to opus ?
I tried with ffmpeg and it works but I had many issues with covers.
same as @[email protected] I use foobar2000 + wine. ffmpeg is alright, but fb2k is very convenient (especially for replaygain tagging). Afterwards I usually give the files a Picard treatment to get proper tags + covers.
I use foobar2000 + wine
Check out Strawberry it’s essentially the Linux native version of foobar2000.
does it support foobar2000 plugins?
probably not, since those are windows dlls. So here’s a short list of what I’d want from a fb2k replacement:
- a UI plugin with the power and flexibility of Facets/Refacets
- browse library by folder structure OR tags (most only do one or the other)
- powerful query language to actually find what I’m looking for
- binaural stereo for headphones plugin
- convolver
- convert to opus and replaygain scanning
- DR Meter
- handle my >100k tracks library without constantly crashing or being incredibly slow
Most alternatives I’ve tried can’t even deliver on half of those.
I use foobar2k via wine. Yes, you may stone me. Tip: You will save heaps of space by not embedding the cover on each file, just put a cover.jpg in the albums folder, virtually any player will pick it up.

Except when streaming the file or copying a random file to another location. embedded art is pretty convenient, 500x500 is plenty large enough and doesn’t take a lot of space (~50KB)
Use opusenc directly. It preserves covers and the CLI is literally
opusenc --bitrate B INPUT OUTPUT.
I also prefer 144k vbr, glad to see I’m not alone.

Because 75MB an album is better than 400MB when you’re trying to pack them on a mobile device. Flac is for archival.
Totally get this, but doesn’t it just matter less over time? 400 megs in my pocket would have been unthinkable some years ago, but now that I’ve got a 500GB SD card, I care a lot less (and thus, why transcode)?
And data storage is always getting cheaper, not the other way around.
Transcoding to a (for them) transparent lossy result is perfectly fine if all you do is listen. I couldn’t care less about “audio qualities” that I cannot hear.
flac on pc, opus on phone. saves storage space

Isn’t the new default codec in BLE Audio LC3 free and open and high quality? And it’s required for BLE Audio support, so there will be more and more devices that support it.
LC3plus isn’t really HiFi. It’s designed to be low-complexity & low energy: https://hydrogenaud.io/index.php/topic,122575.0.html
LC3Plus is more then sufficient for transparent audio at the typical rates you will achieve with bluetooth, 160k is really low and you can normally sustain around 300-600kbps which is more then sufficient for LC3Plus. this test is IMO flawed for the intents and purposes for bluetooth audio
EDIT: LC3Plus caps at 512kbps, I cant remeber if that is before or after FEC (forwards error correction, not to be mistaken with PLC, Packet Loss concealment, FEC is kinda like raid, PLC hides dropped data)
LC3 is default and open, but not high quality LC3Plus is however it has a royalty (albiet very cheap)
PS. Opus Bluetooth is already supported for pipewire->pipewire BT. AAC-LC which is commonly used is fully open source now so thats a good option
Not anything to do with the LDAC codec but why does wireless headphones on windows suck. On linux (even a wm) I just turn on my headphones and it works, on windows every time I have to remove the device and add it back again
[This comment has been deleted by an automated system]
What about wireless headphones that don’t use bluetooth? I think I had some Logitech ones that did not use bluetooth. Are those a viable alternative to bluetooth on linux?
[This comment has been deleted by an automated system]
Bluetooth stacks are notorious for being gargantuan spaghetti code base. People have been trying to put out all those little fires because it’s more possible on Linux than Windows.
The standards are terribly complex and the reference implementations were originally written by the standards groups.
Then to keep compatibility everything has to be broken in the same way as the reference implementations which put more effort into “it works this time” than any kind of resilience.
I was trying to connect headphones on my partners Windows machine and it was a disaster. Most of the time it failed to pair, the rest of the time it paired but didn’t recognize as an audio device. We tried with 2 different devices and both worked perfectly on Linux and Android.
It’s the same for me. I thought it’s due to the motherboard I’m using, windows being the problem never crossed my mind. The only thing that worked well and didn’t have to be re-installed after a disconnect was the new xbox controller, so I feel like maybe there’s something fishy going on here.
Its windows, at which point wasn’t it fishy?
The only thing in my head is the time where people didn’t know it had backdoors and telemetry. I think Windows XP actually didn’t have backdoors but I just assume this rn.
The only thing that worked well and didn’t have to be re-installed after a disconnect
I didn’t have the same experience at all. I’ve used a Bluetooth Xbox controller for years, and it’s worked great… As long as it was only in Bluetooth. If you try to plug it in, let’s say to recharge it or because you want a more reliable connection, you won’t be able to reconnect it in Bluetooth, unless you unpair the device first. Apparently, that is even the _expected behavior", for some reason.
The only way to disable that behavior is to go the the Windows device settings and preventing the controller from being recognized as a USB device, so it only uses the USB as a charging port. Another solution would be to connect the controller to a power plug instead of a USB port of the PC to recharge it, but how unintuitive is that? Imagine if Nintendo, Sony, Apple or even Microsoft themselves on Xbox pulled that? That whenever you plugged in your wireless controller to your device, it suddenly stopped working wirelessly? Out of all the smaller or bigger quirks of Windows, this one has been one of the most unnerving to me for a very long time.
Soundstack has layers of legacy, old, and almost new.
Windows’ built-in bluetooth stack is famously bad. Try installing the Toshiba one instead. It’s a bit clunky UI-wise, but tends to have less issues.
Do you have any guidance on how to do on windows 11?
I’m still on 10 myself so I can’t say for sure. I remember I needed to go into device manager and disable but not uninstall the Microsoft stack, and stop it from automatically updating.
It’ll break the Bluetooth settings/control panel and you’ll need to re-pair all devices via the new icon in the system tray. It looks basically the same as the old one and both might be present, so I advise hiding the old one.
I also seem to recall having to change a setting relating to the pairing password. Maybe? Sorry it’s been a while since I got it set up and it’s worked flawlessly ever since so the details are a bit fuzzy.
Huh, it works just fine for me. I have Samsung galaxy buds 2 pro. I don’t use it with my laptop often, but it’s seamless when I do.
I recommend you all to switch to Pipewire. Most bluethooth problems are fixed.
Most destros default to Pipewire, even Debian 12.
Isn’t that standard on most linux systems?
if your distro is not using Pipewire youre using a shitty one
I’m so confused, please don’t confused a new linux user it doesn’t help me
You can find out if you have pipewire or pulseaudio by using
pactl info | grep "Server Name"You lost me
Pulseaudio used to be the standard audio server.Only recently pipewire has been taking its place.
@Simplesyrup @[email protected]
I believe @twei meant, if you open a terminal and put in the following command:
pactl info | grep “Server Name” the output should tell you what sound server you are using.Or an even better and less nerdy was is just using. System taskmaster and seeing pipewire
Pulseaudio and pipewire are kind of like audio drivers (not exactly but anyway). Let’s say you’re running spotify and discord. They both send their audio to pipewire. You can then use pipewire to control how loud each one is. It also supports more complex use cases like if you’re streaming, you can hook up the spotify output and your microphone mixed together into discord’s input so that the mixed audio will be streamed.
Pipewire is newer and basically replaces another system called jack that did the same thing for pulseaudio.
not only that, but we even get opus for pw to pw bluetooth (handy for streaming audio from a secondary device like a laptop to desktop)

Where the hell do you still buy Anker headphones? I’m in germany and holding on to my soundbuds flow because nothing else even comes close to comparison. I get Anker chargers and adapters and cables and whatever but nothing audio related to a point I thought they gave up on the whole branch.
They use the Soundcore branding currently for their audio products but it‘s the same company
Good to know. Might have to check them out then as my older Sonys die. Iirc DankPods “reviewed” some Soundcore headphones as an alternative to Raycons a while back.
deleted by creator
They are even shipping through Amazon even if bought through Anker/Soundcore website.
Just checked. They are and are all called “Soundcore by Anker so and so”
If you’re looking for a replacement for Soundbuds Flow (i.e. ~€20), you’ll be disappointed. For me, Soundbuds Flow were perfect for workouts. Cheap and I didn’t care too much about sound quality. Anker rebooted their audio line and focuses on mid-range to high-end products.
Micro center carries soundcore products. Where I bought my current P2-L headphones, couple years back.

I have their Soundcore Space A40, and the battery life is legitimately amazing. The case lasts me a week of heavy usage, and the buds easily go 6-10 hours depending on how heavily I use the ANC. If the buds get low, tossing them into the case charges them back up most of the way in 15-20 minutes.
The ANC isn’t perfect, but it’s made my recent flights way more tolerable by cutting out most of the noise from the engines while still letting the voice of my seatmate through.
Yeah Soundcore buds and headphones are damn impressive for their price. The Liberty Pro 2s were my first TW earbuds, and I bought them after reading glowing reviews. I still have them as my backup earbuds.
I agree, I have the soundcore life P2s IMO some of the best budget TWS
Sony did drop the ball with LDAC quite quickly, it could’ve been the new standard.
But with the release of the WH-1000XM3s (or was it the 4s?) they basically made most of the selling points incompatible with LDAC, so now almost no one uses it anymore.
Yes, LDAC and multipoint do not mix hence I’m looking forward to LC3plus that replaces it. To be fair it’s not a big issue to roll back to AAC or even SBC to use multipoint, because you probably aren’t gonna notice a difference when you don’t listen to high res apps like Tidal. It also should be known that a good codec does not fix mediocre drivers and/or chips. Regardless, Linux shines in letting you use a feature you did pony up for. :)
AAC hurts my ears. Not sure why since I can’t hear a difference between it and LDAC without listening very carefully, but after half an hour or so I need to switch it to something else because it becomes more and more uncomfortable.
Switching between LDAC/multipoint mode means rebooting the headphones and connecting them again, so it’s a massive hassle. That makes multipoint absolutely useless to me. I personally won’t be buying sony headphones (or anything else that comes with an app) in the future because of that.
Aac has a higher frequency response and I think some decoders don’t filter transients as well with a fir filter. I’ve noticed this too.
LDAC and Multipoint do in fact mix, just not on Sony products.
I see, so Edifier and Soundcore shall do some homework as well: LDAC and multi point don’t work there either.
Have a look at Technics A800/AZ60/AZ60MK2/AZ80, all support simultaneous use of LDAC and multipoint. I recall something else working with both simultaneously too, possibly Huawei TWS.
They do step down a quality tier to do so, and low bitrste LDAC is generally considered poor, but it’s otherwise all there and possible.
I have a Radsone ES100 Bluetooth DAC/headphone amp, and that supports LDAC, multipoint, and doesn’t compromise the LDAC bitrate when you have multipoint enabled. You can even leave it plugged in as a USB DAC and still use multipoint BT with LDAC, and it switches smoothly between the sources depending on which device started playing a stream most recently.
I was distinctly underwhelmed by the BT implementation when I got my Sony XM4s, it’s kinda weak by comparison.
Nice one!
I am distinctly underwhelmed in general by the XM4.
Yeah, I agree.
I bought them for their noise cancelling primarily, and they’re excellent at that, but otherwise they’re not great. The un-EQed frequency response is terrible for headphones in their price range: flabby, wildly over-exaggerated bass and no mids at all. Running without EQ I can barely hear lyrics - every singer sounds like they’re mumbling underwater. I’ve had $20 IEMs with better tonal balance. They respond well to EQ but the on-board EQ doesn’t have enough frequency bands to even come close to fixing them. Wavelet on Android doing EQ duty makes them listenable. Even when you do EQ them properly, they still sound a bit dull and lifeless.
No idea how they got so much praise when they were launched. The power of marketing budgets I guess. For a while I was gaslighting myself thinking I had a faulty pair or maybe there was something going wrong with my hearing, but having heard another pair, and doing comparisons with my other headphones - most of which are far cheaper - I realised that no, they’re just not very good as headphones.
Oh LDAC conflicts with mutli-connection? That’s why I can’t get it on my 1000xm4?? It’s good to finally have an answer.
On my headphones, you can either use LDAC with one device or SBC/AAC with two devices. I can only change it via the app. Is there a similar setting for you?
The ios app is the only way that I can command the headphones to connect to a second device. When 2 device mode is going on, I have no idea what the connection is like in ios but Linux plainly tells me that it can only do SBC and SBC-XQ. When I turn off 2 device mode, and pair it again, LDAC is finally offered. My 1000xm4 doesn’t offer AAC, I don’t think I have anything around that sinks AAC. My Steamdeck can work as an Opus sink lol.
it was the wh-1000xm3. I own a pair and can confirm most features don’t work with ldac
LDAC never could have been the standard because it’s marketing crap, ctrl+f my name on this post and I have pointed out why multiple times
Ldac is not actually that good, it’s actually fairly rare that LDAC beats out something like SBC XQ let alone AAC
EDIT: for elaboration, LDAC works at 3 main data rate ranges 990/909, 660/606 and 330/303. Ldac is only high res at the 990 range, and even at that range, it still often looses when pipewire is compiled against libfdk. keep in mind that it’s hard to get real numbers on LDAC because decoding is proprietary, meaning I had to disassemble headphones and connect those for verification, but typically AAC on supported headphones beat out 990kbps LDAC (which is hilarious btw considering LDAC can rarely actually work at 990kbps anyways) and both SBC-XQ and LC3Plus (both of which are usable with pipewire) regularly beat 660kbps LDAC.
TLDR LDAC is crap and SBC-XQ is typically more accurate and lower latency, and LC3Plus is even better then that. and if you have AAC compatible headphones assuming latency isnt a major issue (which you are using LDAC so it’s not) just use AAC, both fidelity and latency is better
EDIT: I should mention, it is known that vendors will tune codecs, I believe Valdikks article in habr briefly goes over this. so it’s very possible that tuning could mean that x codec, including LDAC could be the only good codec, however with how badly LDAC maintains 990kbps, I doubt it will make much of a difference
keep in mind that it’s hard to get real numbers on LDAC because decoding is proprietary
I used to think the same. But as it turns out, a decoder exists. Maybe some people don’t want anyone to know about it to keep the myths alive ;)
EDIT: Also, as a golden rule, whenever anyone sees the words High-Res in an audio context, they should immediately realize that they are being bullshitted.
just because a decoder exists doesnt mean it’s good and usable, and it also doesn’t mean you are legally allowed to use it without the appropriate licensing
Lemmy instance choice does not check out ;)

The codec is basic, uses decades-old tech, and was trivially REed.
the point is, it’s not something I’ve been able to test, and im not sure if this will change that, But I suppose I can at least do testing with what I have.

at 990/909 kbps bluetooth can hardly hold that bitrate unless you have really good conditions so much as walking down a stream will bring it down to 660kbps
and yes, AAC does have better fidelity, at 320kbps AAC and Opus are largely transparent to 90% of users keep in mind I am comparing fdkaac on Pipewire, NOT android, this is an important distinction since they were testing android, and you can see here how spotty AAC is on android https://www.soundguys.com/the-ultimate-guide-to-bluetooth-headphones-aac-20296/
I am talking specifcally about linux in this context
EDIT: also it’s not about being an apple fanboy, Opus is largely just as good, marginally better, but no headphones support them, if you want you can even compile pipewire with higher bitrate limits on opus for stereo, (IIRC the pro profile can override it? cant remember but code is here https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/spa/plugins/bluez5/a2dp-codec-opus.c)
opus is transparent for all the the most intense songs by 160kbps, and for regular stuff you’d hear on the radio it’s transparent anywhere from 96kbps-128kbps
while this is the case for a lot of songs, a lot of instrument heavy songs can cause noticeable artifacting for some people. It’s pretty rare, but in the end, it’s not like we are storing the media so why care? we can do upto 320kbps for a stereo stream, and as far as I am aware, it’s not like there are any detriments to doing so (maybe marginally higher power usage I guess).
I wasn’t able to myself, but I did have a friend test the snug space endless lane, and they were able to fairly reliably tell the difference between 128kbps and the original rip. the In the moonlight track too has a high pitch… triangle maybe? that can exhibit artifact too.
so like, yeah, but we have the 320kbps we can work with, so like, why not?
You all got a valid point… it’s just that mileage varies and x codec will sound better in y combination. If I remember right, AAC on Android is at times implemented differently than on it’s home Apple: The encoder would work with smaller bitrates to save battery. There must be a special synergy for max bitrate LDAC to sound worse than AAC, indeed. All in all my post is about being open minded and giving you the option to use a thing, rather than finding out what codec is universally the best: You virtually can’t, can you?
LDAC claims are completely bullshit.
LC3plus is worse than AAC quality wise (to be expected). Lower latency is the only thing going for it. And that’s just because AAC is a very high-latency codec. Opus (as a format) would win on both fronts, although there could be issues with creating a high-quality encoder for it that is not too complex, and power-efficient.
After testing LC3Plus, Opus, and AAC personally for bluetooth, LDAC claims are BS, but for the usecase for bluetooth, LC3Plus is more then sufficient, I don’t know why people keep quoting this post, under normal usecase, you get 3-6x the bitrate being tested, under which case all three codecs sound transparent with LC3Plus maybe dipping a little low. however latency is significantly better then AAC (tested against libfdk) and marginally better then opus
After testing LC3Plus, Opus, and AAC personally for bluetooth, LDAC claims are BS
How did you test Opus for bluetooth?
latency is significantly better then AAC (tested against libfdk) and marginally better then opus
In case you didn’t know, you can use 10ms (or even 5ms) frames with Opus instead of the default (20ms). 10ms should roughly match LC3plus’s default latency while still retaining high quality.
Pipewire currently supports opus for both ways 10ms is what I benched against and for testing you get a wackload of SBCs and Bluetooth chips and test that, 5ms frames were largely unusable. I wanted to take a look at the pinebuds, but it cost like 40 dollars in shipping or something retarded like that to canada, and im not gonna bother with that
and for testing you get a wackload of SBCs and Bluetooth chips and test that
I asked because I wasn’t aware of any consumer buds supporting Opus. I wasn’t aware of PineBuds, thank you for mentioning them.
if you want something else, google headphones support opus, but it uses their own headers and stuff so it’s not compatible with pipewire, only google phones IIRC
I actually prefer AptX HD but I wish my Android would default to it instead of LDAC
Why do you prefer AptX?
The HD version is pretty good, lower bitrate, but solid quality and tolerance for distance.
Ldac if it’s an option, aptx HD otherwise.
Isn’t aptx majorly encumbered by copyright?
LDAC is worse
* patents and yes, I believe so? Just like LDAC. Although AptX is very old, so most of those might have expired by now.
Side by side test with my headphones showed better speration of the range (including bass) and a more solid connection, especially while flying. Kept having LADC constantly try to bitrate switch on me, and when I set it on highest quality it kept cutting in and out at times. Sample size of 1 so YMMV.
Better latency, better reliability, and better quality under normal listening scenarios
You can typically change this in developer options.
You can change it once connected, but every time it defaults back to LDAC
You can change it once connected, but every time it defaults back to LDAC
ah, yeah a couple phones do this, IIRC SetEdit can fix this, but you should be careful if you do try to use it since it opens up a lot of settings that shouldnt be tinkered with
I’ll look into SetEdit, thank you!
For me it all depends on what I connect to, my head unit in the car defaults to AAC, my portable BT speaker is using LDAC, my bookshelf is using AptX-HD.
Thanks Android for supporting all of them automatically!
Definitely. I have a pair of pixel buds that give me very noticeable latency when paired in Windows. I’ve never been able to find a way to use the low latency codecs to fix this.
In Linux it’s a complete opposite experience. I have a menu with every codec in the book, and I can actually watch video in Linux without even noticing any latency now.
Shame about headsets though - has anyone been able to get the mic to work without the audio quality dropping to trash? It is a shame to have to pick between good quality audio and the ability to use your mic.
It’s because all the good codecs (aptX, LDAC, even SBC) all operate over the A2DP Bluetooth profile, meaning your computer’s Bluetooth adapter is running in a particlar mode called A2DP. Unfortunately, A2DP is unidirectional, (ie, not Duplex) it doesn’t support sending audio to headphones and receiving audio from the mic at the same time, due to bandwidth limitations. So when you open Zoom or Teams or something that needs to access your mic, your Bluetooth adapter switches to a different mode like HSP (Handset Profile) and HFP (Hands Free Profile). These profiles do support duplex connection to the mic and headphones, but don’t have fancy high definition codecs. They are designed to be very low bitrate. That’s why you encounter such a big audio quality difference when it switches.
Note, having said that, pipewire on Linux does support some fancy faststream duplex modes that operate on A2DP, outside the constraints of what I explained above. Eg, it gives me the option to enable AptX-LL with faststream, that passes the mic through using whatever little leftover bandwith is on the connection. This doesn’t work with heavier codecs like AptX-HD. I think Android does something similar, that is why you don’t notice the profile swapping behaviour as badly on Android.
A2DP itself does support bidi, faststream is a A2DP BIDI profile (it’s SBC, it’s bad because of really bad bitrate constraints for some reason though) AptX-HD actually support aptx-ll but I find most devices just bug out when you try it. opus also supports bidi on pw.
bandwidth limtations are not an issue with bluetooth itself, you can reliably maintain 300-600kbps, which is more then enough for good quality bidirectional audio. even when using asynchronous modes, you still usually have enough bitrate for audio that would be considered fine.
im not sure why it’s not more popular in modern devices, IIRC all the patents on the subject have ended, could be a limitation of low end radios
I don’t think there are any hifi headset profiles, AFAIK.
I think that might be the codecs’ fault. At least for me, my headphones sound terrible in headset mode on all the devices I’ve tried, regardless of whether they’re running Linux, MacOS, iOS, or Android.
It’s the profile, not the codec. The codec just defines how the audio is compressed, the profile defines all the parameters around that like duplex for microphones.
A2DP is the profile used for music by everything, HFP is the profile that is used for calling by most things nowadays.
TIL! Thanks for the clarification.
And it looks (for me) like on android it just works, so it should be possible… Or maybe it’s just seamlessly switching shit-quality with mic and good quality without? And I didn’t notice during gsm calls?
For sure it sucks on windows too, but well - anything bt-related on windows works just bad…
I feel you there. Personally I just use the earbuds as output and the integrated laptop mic as input. Bluetooth really just doesn’t shine in that regard. However if you’re on Desktop and want everything to happen on a headset, not earbuds x wired stand mic, you should look into things like HyperX Cloud 2 Wireless that employ a USB dongle instead.
I ended up buying JBL Quantum TWS in-ears because they also include a USB-C dongle that speaks their own protocol which allows lowlatency duplex audio. Perfect for audio calls and even gaming. Plus, I don’t need to pair them with every device, I can just bring the dongle. (They can also be paired with Bluetooth and you can switch between dongle and BT whenever you want.)
This is interesting. So these have the “non BT 2.4Ghz” protocol that you generally find in the huge wireless gaming headset?
Ive been looking for a wireless headset that has the low duplex latency of wireless gaming headset, but in a smaller package. Something like the “Microsoft Modern Wireless Headset” but with 2.4Ghz non BT. And I couldn’t find yet something like this.
This is interesting. So these have the “non BT 2.4Ghz” protocol that you generally find in the huge wireless gaming headset?
Yes, exactly.
Actually “Gaming” was exactly the keyword that finally made me find these things. Looking for “normal” headsets/in-ears you can find some that also claim to be optimized for conferences and of course they also claim “low latency”, but looking deeper the best they typically have are aptX-LL or something, which does shit when in duplex mode (unless yours and their bluetooth stack allow some hackery like Faststream). But the gaming-optimized ones typically offer real low latency.
Downside of in-ears is obviously the battery lifetime. I think I need to quick-charge them every 3h. But it’s not often a problem, since most of the time I put them in their charging box during a short (5 minutes or so) break which is enough to boost them long enough that I don’t even notice the battery through out a longer session. Upside - which I wanted them for is - that I don’t have a large headset covering my ears and pressing on my head.
These could be nice upgrade for my Pixel Buds A series. I’m using them for Teams (low latency bad quality). (Not just music high latency high quality).
However, what I really also want to have are gaming headsets (with the long microphone and low latency) that are a bit more low profile and not huge.
At first I thought it was a matter of physics, but after seeing 2.4Ghz low latency in these tiny earbuds I guess it’s possible.
Can’t believe low profile on-ear headsets are not popular. They are all over the ear or huge.
And as you said the ones they generally make for teams sucks with BT high duplex latency.
Overear wireless gaming headsets should be easier to find. Logitech for example builds them for ages. I also had foldable business headphones from Logitech that have their own dongle and bluetooth support.
I found some but they still looked huge and flashy. Not small like the Jabras or Microsoft.
I only care about design because I plan to use them with the webcam on.
I’ll take a look at the page later! Thanks
When I try to fiddle with them they just start producing a hellish noise that breaks my ears in a certain configuration, I had that happen both on Jabra earbuds and Soundcore headphones, luckily the latter has a wire option as well so that’s a relief
You’re gonna need wired or 2.4ghz wireless for that.
Technically, Bluetooth uses 2.4GHz XP
I’m still wondering how to make my headphones work on pop os without crackling
You will not believe this. Solution was adding a line in some config file.
Are you thinking of the standby timeout? Cause I get static on my speakers on any and all distros when no audio is playing. It always happens after 5 seconds of silence. Kinda infuriating that I have to do this on EVERY SINGLE DAMN INSTALL.
For Pulseaudio:
Quickfix (until reboot):sudo su echo 0 > /sys/module/snd_hda_intel/parameters/power_savepermanent fix is to add the line:
options snd-hda-intel power_save=0
to the file /etc/modprobe.d/alsa-base.confFor pipewire:
create folder /etc/wireplumber/main.lua.d/ if it does not exist
if you had to create it yourself just copy over the file from /usr/share/wireplumber/main.lua.d/50-alsa-config.lua
otherwise it probably is there already then just edit it
pretty much at the bottom there is a line that says “session.suspend-timout-seconds”
uncomment it and set its value to 0
then rebootPretty sure this used to be the fix for me:

( scroll down to comment about default.pa and tsched=0 )
But I just checked my default.pa and it is stock values, so I am not sure anymore
When experimenting, setting cpu governor to performance also helped.
Used to have that problem on suse, it was something to do with pulse but I can’t recall, solution was in ArchWiki
Ubuntu user, for me I’ve always had to disable/delete the voice dispatcher, that usually does it.
Switching to pipewire from ALSA cured that for me.
I have the exact same headphones hahaha, this is perfect how are you liking them by the way? I had some connection problems on the first month but this 2nd month they’ve been behaving good
just yes. the sound and anc is day and night compared to my more compact redmi buds 3 pro. I used to diss TWS as a whole until I got these pairs. Had some issues after a firmware update but a factory reset did fix it for me. :)
Any way to see which bitrate is currently being used? I know you can set it to use only 909kbps, 606kbps or 303kbps in the wireplumber config, but I am curious which bitrate the adaptive mode (usually) uses.
I’d love to say the same but on my Lenovo laptop I get frequent disconnects with bluetooth earphones on Linux alone. Apparently it’s a firmware problem with the AX200 board, but even after having updated the firmware and following all the online fixes I still have the problem.
My whole use case for my laptop is getting away from my desk when I want to read something and listen to music at the end of the day, but it’s annoying to have to reconnect the earphones every 10 or so minutes. Like everything Linux, it’s incredible as long as you have supported hardware and you don’t bump into some weird edge case.
Not sure if it’s possible on your laptop but I upgraded my Wifi/BT with a AX210NGW on my Thinkpad. Works perfectly now.
I’m pretty sure it is, I’ll keep that in mind, thanks!
I’ve had BT disconnect issues on a 2015 HP EB 840 G2 paired with my ancient Logitech UE speaker. Not sure if it’s the implementation of bluez on mxlinux or my actual bt hardware on the laptop. The result for me is similar to yours: laptop is flaky, so my phone remains my playback source of choice.

LDAC wins against APTX under normal use situations but not APTX-HD, they are typically about the same with a large latency penalty for LDAC
Is the APTX-HD latency good enough for gaming? (And can be used for VoIP?).
I don’t know much about BT… But I know that my Pixel buds series A, have terrible latency for gaming unless I use them in headset mode (which then has terrible quality).
In isolation aptx-hd when operating in aptx-ll mode is low enough latency that it can be used for gaming, however it’s very rare that standard bluetooth headphones will be low enough latency, at the very least I haven’t personally tested any devices that fit the bill when operating in aptx-hd. Im sure some bluetooth headphones will be able to, but none that i’ve come across. LC3Plus might actually be able to change this. IMO running a bluetooth dac is much more likely to get there.
Thanks for the insight!
