Advanced Sound 747 Noise-Canceling IEMs
Natural Sound, Pitch-Black Background
When your music sounds this good, you don’t want it interrupted by everything else going on in the office or on your morning commute. Luckily, the Advanced Sound 747 IEMs block the rest out. Equipped with a single 13-millimeter dynamic driver and Pitch Black active noise-canceling technology, they reduce low-frequency ambient noise by up to 25 decibels while providing additional amplification for the audio output. The result: full-range music reproduction with a powerful bass response, and beyond it, complete silence. The ANC function can last up to 10 hours on a single charge, and the audio works passively without ANC even after the battery is drained. The 4-foot-long cable has an iOS-compatible microphone and a one-button universal remote, and nine pairs of ear tips are included.
Note: This drop is limited to 300 units.
