Crystal clear calls
Dual beamforming microphones on each earbud ensure crystal-clear call quality, even in noisy environments, by focusing on your voice and utilizing AI technology that reduces background noise. 

Dependable audio connectivity
With Bluetooth 5.3 for stable, drop-free connections plus support for SBC and AAC codecs to deliver rich, detailed audio with every track.
