Listen like never before with QuietControl™ 30 wireless headphones. Breakthrough technology lets you set your own level of noise cancellation, so you can control how much of the world you want to let in—or how quiet you want your surroundings to be. Volume-optimized EQ gives you balanced audio performance at any volume, while a noise-rejecting dual-microphone system provides clear calls, even in windy or noisy environments. Connect easily to your devices with Bluetooth® and NFC pairing. QuietControl 30 wireless headphones feature a lightweight neckband design that conforms to your body for all-day comfort and wearability. A lithium-ion battery gives you up to 10 hours of wireless listening per charge.
