Microsoft is adding LE Audio support to Windows 11 to improve Bluetooth headset audio quality for games and voice calls, signaling a shift away from Bluetooth Classic toward higher fidelity wireless audio.

The upgrade replaces Bluetooth Classic Audio with Bluetooth LE Audio to upgrade headphone sound quality across gaming and voice applications.

Current Bluetooth profiles trade off mic support and stereo quality: A2DP delivers high-quality audio without a microphone, while HFP provides mic support at mono and lower overall quality.

LE Audio enables CD‑quality audio similar to A2DP while allowing microphone use simultaneously, addressing a core limitation of existing setups.

LE Audio introduces super wideband voice at a 32kHz sample rate, enhancing in-game chat and calls without sacrificing stereo game audio.

By switching to LE Audio and leveraging a 32kHz sample rate, Bluetooth headsets can maintain stereo game audio while supporting ongoing voice communication.

LE Audio uses Bluetooth Low Energy to replace the older A2DP/HFP pathway, delivering higher quality, wideband and super wideband audio.

The article notes that LE Audio enables Spatial Audio in Microsoft Teams over Bluetooth, a capability not previously available on Bluetooth headsets, and can be toggled in Teams’ audio settings on Windows.

Hardware and software requirements include a Bluetooth headset that supports LE Audio, a Windows 11 PC with LE Audio capability, and the latest drivers plus the 2024H2/24H2 update; driver updates are rolling out this year and most new PCs from late 2025 should ship with LE Audio support.
