You can't control how noisy your environment is. But with the Bose QuietControl 30 Wireless Headphones, you can control how much of it you hear. Set your own levels of noise cancellation and decide precisely how much of the world you want to let in. QuietControl 30 headphones use proprietary technologies to deliver balanced audio performance at any volume, too. A lightweight neckband design conforms to your body for all day wearability, and StayHear+ QC tips stay secure through the entire 10-hour battery life. And you can leave the wires behind: they're engineered for Bluetooth and NFC pairing so you can connect your devices wirelessly and stay focused on the music.
