I need to adapt a Bluetooth headset (speakers + mic) to 3.5 mm, but the only adapters I can find will either transmit or receive, not both at the same time. Is there some technical limitation why this can’t be done, or is there just no market for such a device? Thanks.

    They’re also often called TRRS (for 4 pole), in relation to TRS (3 pole).
