When your headphones support Bluetooth LE Audio, the Bluetooth quality should no longer decrease when you use voice.
Bluetooth on Windows is getting a major upgrade: soon you can enjoy clear stereo sound and use your microphone simultaneously via Bluetooth Low Energy (LE) Audio. That’s especially good news for Teams users.
No more Muffled Sound
Anyone who makes calls with Bluetooth headphones probably recognizes the problem: the sound suddenly becomes more muffled and less clear. That’s because classic Bluetooth technology (A2DP or HFP) can only combine one of two: either stereo audio without microphone, or microphone with muffled mono audio. Thanks to LE Audio, this no longer happens.
Super Wideband Stereo with LE Audio
LE Audio is the successor to Bluetooth Classic and works more efficiently and smarter. The new profiles combine media and microphone and support super wideband audio with a higher frequency (32 kHz). This should make voice sound clearer.
The update also makes it possible to use spatial audio in Microsoft Teams with wireless headsets. Spatial audio was already available in the chat application, but only works with stereo sound. So this wasn’t possible via Bluetooth before, but it is after the new update. “Conversations sound more natural because voices seem to come from the right corner of the screen,” Microsoft writes in the announcement.
When Available?
Super wideband stereo is available in Windows 11 version 24H2, on devices with LE Audio support and an up-to-date Bluetooth driver. Some existing devices will receive a driver update later this year. New laptops from late 2025 will support the feature by default.
