About this tag
HFP/HSP (Hands-Free Profile/Headset Profile) are Bluetooth profiles that enable two-way audio communication, including microphone input, on Windows PCs. Historically, activating a headset microphone via HFP/HSP forced audio playback to drop from high-fidelity stereo to low-quality mono, a trade-off that frustrated users during voice calls, game chat, or video conferences. Recent Windows 11 updates, particularly version 24H2, introduce support for Bluetooth LE Audio and the LC3 codec, which allows simultaneous stereo playback and clear microphone audio without the HFP/HSP compromise. This improvement requires compatible hardware and drivers, but it resolves a long-standing Bluetooth audio limitation on Windows.
