USB-BT540

With the ability to connect up to 7 devices simultaneously, this adapter allows you to centralize your headphones, keyboards, mice, controllers, and other Bluetooth accessories on one device.

Its ultra-compact design makes it discreet and easy to carry, ideal for use both at home and on the go.

Compatible with the LE Audio standard* (depending on operating system support), it guarantees an optimized audio experience and improved energy efficiency.

* The LE Audio standard is the new generation of Bluetooth audio.

It uses the LC3 codec, which is more efficient than the old SBC: better sound quality with less bandwidth and lower energy consumption.

It also brings:

- Multi-Stream Audio: better stereo synchronization and more stable connections.

- Auracast™: broadcast the same audio to multiple devices (e.g., headphones, speakers).
