> The ModMic Wireless also works around the "Bluetooth sound quality is shit in headset mode" issue, since your headphones are in output-only (A2DP) mode
I will never understand for the life of me why the hell bi-directional high-quality audio over Bluetooth still isn't a thing, even in 2025.
Bluetooth has MORE than enough bandwidth. 320 kbps output gives you damn near lossless quality, and just 128 kbps would be plenty for single-channel microphone audio, and honestly even just 64 kbps would be be fine. You would need at most 500 kbps. Bluetooth is capable of more than that.
Even if there's no bidirectional high quality standard (HFP is bidirectional, but low quality), Bluetooth allows simultaneous logical connections of multiple profiles at the same time. Sure, your computer has an A2DP connection as the source to your headphones as a sink. Why can't a headset also open a second A2DP connection with itself as the source and the computer as the sink?
It just doesn't make sense that a spec that's been around for what, 20 years has failed to keep up. I hate that as a gamer, I can't use the Bluetooth built into my motherboard to use a gaming headset if I want high quality audio. I have to get a headset with a proprietary dongle and then remember to bring it with me to LAN parties.
Bluetooth 5 added audio for BLE called LE Audio with LC3 codec. BLE has higher (24 Mbps vs 1 Mbps) bandwidth than Bluetooth Classic. Bluetooth 5 headphones are available now.
That would have been perfect time to update headsets. It sounds like A2DP can do backchannel now and there is Qualcomm proposed FastStream. But it isn't implemented widely and probably won't be until standardized.
