a2dp vs hfp

About this tag
The tag a2dp vs hfp covers the longstanding Bluetooth audio compromise on Windows where activating a headset microphone forces a switch from high-quality stereo (A2DP) to low-quality mono (HFP). Recent Windows 11 updates introduce Bluetooth LE Audio support, including the Telephony and Media Audio Profile (TMAP) and the LC3 codec, which allow stereo audio and microphone use simultaneously without degrading voice quality. This is a platform-level change requiring Windows 11 22H2 or newer, compatible Bluetooth hardware, and drivers. The tag discusses how LE Audio and super-wideband stereo fix the old A2DP vs HFP trade-off, particularly for gaming and voice chat scenarios.
