Similar to the original version of QuietComfort 35, the headphones are available in black and silver are also equipped with noise cancellation technology and best audio performance by Bose, and support the maximum battery life claimed for 20 hours.
The headphones are also equipped with the same key configuration, with audio volume buttons on the right earcup, accompanied by multifunction buttons to dial incoming calls and access to Siri.
The difference between QuietComfort 35 II when compared to its predecessor lies in the new Action button on the left-side earcup. This button lets users connect headphones to Google Assistant without the need to use the phone, unlock and search for applications.
QuietComfort 35 II is the result of collaboration between Bose and Google, making it the first headphone with Google Assistant integration. In addition, these headphones are also equipped with Bose's microphone system, claimed to be able to capture sound with the best accuracy.
Google Software Engineer Ian Lake also explains that the headphones are also equipped with Voice UI (VUI) feature, allowing the device to read out the sender's name when receiving message notifications. These features work well on iOS devices as well as via the Google Assistant app.
