Truly Wireless Active Noise Cancellation Technology

With the technology of Earbuds, you can select compatible communication devices without using cables. Earbuds do not require keeping the phone-facing earphones directly, but the maximum distance between them should not exceed 10 meters (about 30 feet).

Using active noise cancellation technology, the microphones collect the noise, then the acoustic engineer calculates and designs a series of software and hardware algorithms, the circuit generates a reverse sound wave that is opposite to the noise and emits it through the horn. Finally, the noise and the reverse sound wave cancel each other.
