Features:
Split true wireless design, breaking the master-slave limitation, the left and right earbuds can be taken and used independently.
Each headphone has built-in two high-sensitivity microphones, and uses beamforming technology to eliminate background noise during the call, so that you can have clear calls even in noisy environments.
Adopt 14.2mm large size composite diaphragm dynamic coil unit, the sound is fuller and thicker, the sense of hearing is natural, and more real texture and details are restored. It supports AAC audio codec technology, which brings the improvement and experience of the sound quality that can be heard.
The semi-in-ear wearing design is adopted to better fit the ear canal, giving both ears a stable and comfortable wearing experience. The single earphone only weighs 4.7g, and the small and light body makes it easier to wear, greatly reducing the fatigue of long-term wear.
When you open the charging case, the phone will pop up the headphone connection interface, which is more convenient with visual operation. After connecting, you can also view the power of the headphone and charging case.

High-sensitivity capacitive in-ear wearing detection can detect the wearing state. When the headphone is removed during music playback, the music can be paused and re-worn to play. 
The new architecture is used to deeply optimize the software and hardware, and the left and right ears are connected synchronously to transmit sound signal to the left and right earphones synchronously. More stable anti-interference ability, effectively reduces sound delay.
