QuietComfort 35 wireless headphones II are engineered with world-class noise cancellation. And now they’re optimized for Alexa and the Google Assistant. Choose which is right for you for help on the go. Press the Action button to enjoy entertainment, get information and manage your day—without looking at your phone. If you don’t use the Google Assistant or Alexa, you can still use the Action button to adjust your level of noise cancellation. The multi-function button offers access to your phone’s default virtual assistant, like Siri. Bluetooth® and NFC pairing free you from wires, while voice prompts make connecting easy. 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. The headphones feature up to 20 hours of wireless listening per charge and are designed with premium materials that make them lightweight and comfortable. Unlock more features and future updates with the Bose Connect app. With the included cable, you can keep listening even if you forget to charge.
