Pitch Black Active Noise Cancelling Technology provides complete silence and luscious bass in the most noisy environment.
Pitch Black ANC Technology The "Pitch Black" Active-Noise Cancelling Technology used in ADVANCED 747 utilizes the built-in microphones and the proprietary electronic algorithm to reduce the low frequency ambient noise up to 25 decibel while simultaneously providing additional amplification for the audio output, which results in full-range music reproduction in complete silence.
Luscious, Powerful Bass Response Additional amplification from the Pitch Black Technology completely transforms the sound that ADVANCED 747 produces into luscious and sibilant-free ensemble with its powerful bass response. ADVANCED 747 achieves the highest sound quality among all available Active Noise-Cancelling earphones in the market.
10-Hour Battery Life The Active Noise-Cancelling function can last up to 10 hours on a single charge. The audio still works passively without the ANC function after the battery is drained. The battery can be fully recharged in about 1 hour, ready for another go.
In-line Remote / Mic The in-line remote provides convenient controls for music playback and answering/ending phone calls with the built-in microphone. The remote and microphone function is compatible with iPhone, iPod, iPad and most smartphones and tablets with 3.5mm jack.
