special function:
1. Abandon the traditional earphone design, the binaural sensor non-earphone earphone earphone design, hesitant to the swelling caused by earplugs. Our wireless headsets use the latest Non-In-Ear technology and don't hurt when used for long periods of time.
2. Voice dialing: Press and hold the multi-function button for about 2 seconds to start voice dialing.
