The UGREEN CM276 Bluetooth 5.0 Receiver Audio Adapter transforms any wired speaker, car stereo, or headphone into a wireless Bluetooth device — giving you the freedom to stream music and take calls without cables.

Powered by Bluetooth 5.0 technology with a CSR chip, CVC 8.0 noise reduction, and a signal-to-noise ratio of over 90 dB, it delivers crystal-clear, natural sound whether you're listening to music or on a phone call. The impressive 10-meter wireless range ensures stable, uninterrupted connectivity, and if the connection ever drops, it automatically reconnects as soon as your device is back in range. With the ability to pair with 2 devices simultaneously, you can play music from one phone and take calls from another — switching intuitively between both. The built-in microphone makes it perfect for safe, hands-free calling in the car.

A long-lasting battery delivers up to 9 hours of playback or 300 hours standby, and recharges fully in just 2 hours — so it's always ready when you need it. The compact ABS and aluminum construction keeps it lightweight, durable, and travel-ready.
