You can't control how noisy your environment is. But you can control how much of it you hear. Set your own levels of noise cancellation with QuietControl 30 earphones, and get balanced audio performance at any volume. A lightweight neckband design conforms to your body for all-day wearability. A precise arrangement of microphones inside and outside the earbuds to continuously measure, compare and react to noisy environments. The system then produces an equal and opposite signal to cancel the noise. The StayHear+ QC tips also form a gentle seal for additional passive noise reduction. Leave the wires behind'without sacrificing performance. The volume-optimized EQ delivers consistent, balanced sound at any volume. And they're re-engineered with Bluetooth and NFC pairing, so connecting to your devices wirelessly is quick and easy. An inline remote lets you take/end calls, skip/pause tracks and control volume without reaching for your device. The Bose app makes connecting and switching between devices easier than ever. So you can focus on the music.
