Bose QuietComfort 35 II Wireless Bluetooth Headphones Review

By | March 28, 2020

QuietComfort 35 II, first released in 2016, is an upgrade of the QuietComfort 35 model. It is compatible with the innovative Google and Alexa voice assistants while still maintaining its tip-top active noise-canceling function, 20-hour battery runtime, and convenient wireless operation making it a favorite among on-the-go individuals.

It also maintains the design of QuietComfort 35 and the previous QuietComfort 25 model which was released in 2014. There is a lot more going for these headphones that would persuade you to buy them over other models.

  • 20-hour battery time
  • Compatible with the Bose Connect app


  • Comfortable fit

On the outside, the headphones look classic with a slim profile but do not come out as overly striking in style. Nonetheless, they are durable and the tough case included in the package helps you store the headphones safely.

QuietComfort 35 II is available in three colors - black, silver, and rose gold and features a solid plastic adjustable build that makes it both lightweight, comfortable, and better fitting than its predecessors.

The ear cups are amply padded, so apart from delivering comfort, they provide excellent noise-canceling especially during those moments when you will turn off the ANC function to save battery charge. Even so, some padding on the headband would have been a thoughtful comfort feature in the QuietComfort 35 II.

This headphone has its controls on the side of the right ear cups. The innovative Google assistant activation button is positioned on the left ear cup. Since it is positioned separately from the other control buttons, it makes it much easier to handle.


Bose QuietComfort 35 II retains the same sound quality as the QuietComfort 35 model. Well, it doesn’t support Codec but is compatible with AAC making them low on latency which is good but not the best you can have.

The soundstage is soft and pleasant both on the low and high ends and best in the mid-range. However, it is a little lacking in detail compared to other headphones with more pronounced bass and piercing highs. For this reason, it may not deliver the best bass performance when the volume is at its maximum, especially on the low end. This shouldn't be much of a problem considering that your ears don’t need that much sound anyway.

Perhaps, the greatest selling point for these headphones is its ANC function. At its best, this feature eliminates most if not all ambient noise. Together with the adequately padded ear cups, QuietComfort 35 II excels at noise-canceling both when the ANC feature is activated and when it is turned off.

On the other hand, the call quality is excellent with clean and clear sound transmission. The ANC function turns off automatically when calls come through.

Finally, this headphone is compatible with the Bose AR app which means that it comes with inbuilt motion sensors to deliver an immersive listening experience. This app is now only compatible with iPhone and iPad devices. However, once apps for android devices are developed, users will have much to benefit from this headphone.


Bose QuietComfort 35 II is built with a dual-mic system that works well to shut out ambient noise while picking up voice and sound quite clearly.


Bose QuietComfort 35 II is equipped with both Bluetooth and NFC pairing. Still, when you need to save your battery charge, the 3.5mm audio cable comes in handy.

Overall, the connection is strong throughout both for music streaming and voice calls over a 33-feet range which is just the standard range for most headphones.

Secondly, this headphone comes with the ability to connect to two devices simultaneously. It also allows music sharing which is an added advantage.

When using this headphone for the very first time, you will be prompted to install the Bose Connect app from which you manage functions like the ANC and the voice assistants. It is also used to map the Google assistant action button to set active noise canceling to different levels i.e high, low, or switch it off altogether.

Bose QuietComfort 35 II features a simplified control set up. The right ear cup holds the control buttons used for volume, power, Bluetooth, call, and playlist management. The left ear cup holds the voice assistant action button. There is also a micro USB port and a 3.5mm cable input that allows you to connect the headphone to your phone through a cable.

A unique function in this headphone is the ability to indicate the battery level and the fact that it allows you to schedule the timer to turn off the power.

Battery power

This headphone is powered by a Lithium-ion battery with 20-hours runtime when the ANC feature is activated, which is considered better than other headsets in its league. Charge it with the micro USB cable included in the package. Still, you can connect your headphones directly to your device using the 3.5mm audio cable.

Additional features

As already mentioned, the outstanding feature in this headphone that you will not find in the previous versions is the dedicated Google Assistant action button that doubles up as the ANC control button when you don't need Google Assistant.

Final verdict

Should you purchase this headphone for its active noise cancellation?


Should you purchase it for the voice assistant feature?

Perhaps not. However, this is an excellent addition to Bose QuietComfort 35 II headphones and will certainly make a difference in your listening and user experience.

Overall, this headphone delivers soft, well-balanced sounds on both ends. With a superior noise canceling function at feature and design level, a decent battery life, and incredible comfort, there is a lot to be admired from it, especially by people who are constantly traveling.
