With an advanced chip that guarantees exceptional performance and lossless audio streaming, you can count on a stable connection signal within 20 meters between the earphone and your phone.

But that's not all - our headphones also feature TF Card MP3 Music Mode with clear sound and HIFI bass, thanks to a 10mm large strong magnet speaker that delivers outstanding music quality. Plus, with CVC Audio Technology, background noise is cancelled out during calls for crystal-clear communication.

Worried about battery life? Don't be. Our headphones boast an impressive 500mAh battery that provides all-day listening capabilities. Enjoy up to 40 hours of music time after a full charge, along with about 300 hours of standby time.
