Through 11 mm dynamic drivers, the headphones deliver rich, detailed sound, compatible with SBC and AAC audio codecs.

Open design with comfortable fit

Lightweight construction naturally blends music with surrounding sounds for better perception. They can be worn individually if you want to be even more aware of what's going on around you or take part in conversations. They also come with IPX4 certification for sweat and splash resistance, so you can use them on rainy days without a problem.

Multipoint connectivity and noise-cancelling calls

Connect up to two devices at once and switch between them seamlessly. They come with smart touch controls for intuitive use, smart pause when you remove an earbud and dual microphones with intelligent noise reduction to filter out ambient noise during calls.

400 mAh battery

On a full charge, each earbud delivers 6 hours of continuous music and up to 28 hours of battery life with its charging case. A 10-minute quick charge will give you an extra 1.5 hours of playback time.
