This update addresses longstanding issues caused by the traditional Bluetooth profiles, A2DP and HFP, which limited audio quality and microphone functionality, especially during calls.

The new profile, based on Bluetooth Low Energy (LE Audio), uses the LC3 compression algorithm and a 32kHz sample rate, replacing the older Bluetooth Classic profiles that operated at 8kHz, resulting in better sound clarity.

Supported devices will be able to stream super wideband stereo audio during calls, maintaining high quality even when the microphone is active, a feature previously hampered by the switch to mono audio.

Microsoft is also introducing spatial audio in Microsoft Teams, providing 3D sound based on speaker location to improve situational awareness during video calls, leveraging the 'cocktail party' effect.

This update will be available in a preview build soon, with full deployment expected later in 2025, though device compatibility with LE Audio is required for the new features.

To benefit from these improvements, users need a Windows 11 PC supporting version 24H2 or newer, along with Bluetooth LE Audio-compatible headphones and updated drivers.

While the upgrade enhances audio quality and microphone support, it does not fully resolve latency issues in wireless gaming headsets, but it ensures stereo sound during voice calls.

This development is especially important for gamers and professionals, as it enables clearer in-game voice chat and crisper call audio, reducing reliance on wired solutions.

Older Bluetooth devices that do not support LE Audio may still face limitations, and interference or outdated drivers can affect performance, but most new devices from late 2025 are expected to support these features.

This update marks a significant step forward in wireless audio technology, promising higher fidelity, better spatial effects, and more natural sound during calls and gaming.

Microsoft is rolling out a Windows 11 update that significantly enhances Bluetooth audio support by introducing LE Audio, which allows for high-quality stereo sound and microphone use simultaneously.

The move aligns with industry standards like Bluetooth 5.2 and LE Audio, aiming to make Windows 11 more competitive in multimedia and connectivity features.
