Bose QC35 wireless headphones II are known for their ability to clear away noisy distractions so you can focus on your music, your work, or whatever your passion. Proprietary Acoustic Noise Cancelling technology continuously monitors and measures outside noise and then cancels it with the opposite signal. You can adjust between two levels of active noise cancellation using the Action button or the Bose Connect app. QC35 wireless headphones II are also optimized for the Google Assistant and Alexa, so you can enjoy entertainment, get information, and manage your day — without looking at your phone. Volume-optimized EQ gives you balanced audio performance at any volume, and a noise-rejecting dual-microphone system provides clearer calls, even in noisy environments. These headphones also feature easy Bluetooth® pairing, 20 hours of battery life, and a durable, comfortable fit. Available in Black or Silver.
