The QuietComfort 35 wireless headphones II feature first-class noise reduction. And now they are even better - thanks to an action button with which the noise reduction can be individually adjusted in three stages. You can also use the multifunction key to access the pre-installed virtual assistant of your smartphone, such as Siri. Plus, you'll enjoy wireless freedom with Bluetooth and NFC pairing with supporting voice prompts that make pairing even easier. The specially tuned EQ provides lifelike sound at any volume and when you're on the phone, annoying ambient noise is effectively filtered out by a dual microphone system. The wireless playback time of the headphones is up to 20 hours per battery charge and high-quality materials ensure that the lightweight headphones are always extremely comfortable to wear. Use the Bose Connect app to unlock additional features and take advantage of future updates. And if there's not enough time to charge the battery, the included cable makes sure you can still listen to music. Available in black, silver or as Limited Edition in dark blue.
