M19 Wireless In-Ear Earphones With Charging Box Black

1. Double active noise reduction technology, endless. The microphone outside the ear detects the ambient sound, and the earphone emits reverse phase to eliminate the noise wave; at the same time, the microphone inside the ear captures the excess noise and emits the reverse noise reduction wave again to eliminate it twice. The dual active noise reduction technology realizes the double noise reduction effect, and the maximum noise reduction can reach 32dB, bringing you a pure noise reduction experience. 2. The two microphones outside the ear use "beam forming" technology to accurately pick up the voice, avoiding the surrounding noise interference, and only your voice; the one microphone in the ear picks up the pure voice conducted by the inner ear canal, effectively weakening the call noise and letting the other party Listen more clearly. 3. Adopt a sensor more suitable for human touch, which can sensitively control music, call and noise reduction with a light touch, bringing a comfortable and convenient control experience, with anti-mistouch algorithm, effectively reducing the accidental touch. 4. Built-in 10mm large-size moving coil unit makes the bass performance more powerful. 5. Support short-range Bluetooth connection.
