“Man is by nature a social animal”, said Aristotle, and that remains as true as ever. We text, tweet and message each other – and some even employ smart assistants such as Amazon Echo or Google Home to help streamline their communication.
But now we are talking to our speakers, our watches and our phones, it makes sense that we should be able to talk to our headphones as well. That’s the thinking behind the Bose QuietComfort 35 II, the updated version of the QuietComfort 35 that came out in 2016.
These 2017-released headphones have a dedicated button to activate Google Assistant, which will, at your behest, play music, answer trivia questions and read to you your smartphone notifications. Add that to the QC35 II’s great audio quality and noise-cancelling capabilities, and you have a pair of cans with very widespread appeal.
The QC35 II now have successors in the 2021-released Bose QuietComfort 45. In the years since their arrival, they also have another premium wireless noise-cancelling over-ear sibling in the Bose Noise Cancelling Headphones 700. But despite their relative age in the Bose headphones line-up, they're still available and appealing options – not least as there's often a QC35 II deal knocking around.

Mainly found in Android smartphones, Assistant is Google’s equivalent of Apple’s Siri or Amazon’s Alexa.
Once set up through Bose’s Connect app – or, for Apple users, the Bose app combined with Google’s Assistant app for iOS – the QuietComfort 35 II will chime whenever your phone gets a new notification or automatically read out upcoming calendar events.
Receive a text or other online message, and press the button on the left housing to have Google Assistant read it out. It then gives you the option to reply using your voice. It’s a handy addition, especially during the winter months: it’s much simpler to respond to texts or make calls at the push of a button than it is to fish your phone out of your pocket, remove your gloves and bash out a hasty message with frozen fingers.
There are some limitations, however. While you can use these headphones to control and play your music, you’ll need to use Spotify in order for Google Assistant to work.
It’s currently unable to access your offline media or link with other services such as Tidal or Deezer (and if you’re on iOS, we found it unable to stream music using the Assistant at all).
If you’re connected to both a laptop and a smartphone (the QuietComfort 35 II have the ability to connect to two devices at once), we find that activating the Google Assistant to read a notification on our phone also starts up iTunes on our MacBook.
For some reason, it also refuses to read out your contacts’ surnames, so if you have multiple people of the same name in your address book, you’ll have to work out who your message is from.
We imagine that Android users will get more out of this functionality than Apple users, though. The synergy between these headphones and Android just seems slicker than with an iPhone.
If you aren’t bothered about the smarts, you can program the button to cycle through the headphones’ three noise-cancelling levels instead (‘low’, ‘high’ or ‘off’).
Like the original QuietComfort 35, the level of noise-cancellation from these cans is impressive.
Bose has always been at the forefront of silencing constant rumbles or hums, and that remains the same here – the microphones inside and outside the headphones effectively eliminating any irritating background chatter.
If we have one complaint, it’s that the noise-cancellation could be a little more intelligent, for example in the same way the Sony WH-1000XM3 headphones disable noise-cancellation when you hold your hand over one of the housings.
B&W’s PX headphones pause your music when you lift the earpad up, allowing you to have a quick conversation. We’d liked to have seen similar features in these headphones.
Battery life is a claimed 20 hours with a wireless connection, or 40 hours of just noise-cancellation if you’re using the 3.5mm cable that comes in the box. Charge the headphones using a micro-USB cable and you get an extra 2.5 hours of juice in just 15 minutes.
Battery life 20 hours (BT and ANC); 40 hours (wired and ANC)
The QuietComfort 35 II certainly live up to the 'comfort' part of their name. At 310g, they are significantly lighter than the B&W PX and have a softer grip than Sony’s headphones.
Those needing a pair of noise-cancellers for long journeys should definitely bear these in mind.
The hinges on the housings mean the headphones fold down nicely, and their build quality suggests that they could survive being kept in a rucksack, without the need to keep them in the carry-case that comes with it.
The buttons around the right housing control playback. They are intuitively placed and feel good to use. You’ll soon get used to the series of taps needed to rewind or skip your songs.
The QuietComfort 35 II have great handlings on any music you send their way. We begin with The Beatles’ Let It Be (opens in new tab), connected to a MacBook Pro, and these headphones impressively manage to dig up details you might not otherwise hear.
Paul McCartney keeps irregular timing when building up to the chorus, singing lines a little later than you’d expect. When he does, the QuietComfort 35 II pick up the barely audible sounds of the faint movements of his lips easily.
Playing Teenagers (opens in new tab) by My Chemical Romance, these headphones pay great attention to the midrange. There’s no denying the scornful assonance in Gerard Way’s lyrics and the snarl as he laments the loss of teenage individualism.
Each powerful bass note is weighty and nuanced; from the lowest depths as the drumstick hits to the way the sound disperses and fades into the soundstage, you can make out numerous layers to the sound where less talented headphones would struggle.
On the other end of the sound spectrum, these headphones keep a controlled and measured management of the high treble.
The soaring vocalisations in Now We Are Free (opens in new tab), from Hans Zimmer and Lisa Gerrard’s Gladiator (opens in new tab) soundtrack, are far reaching without any hint of a sounding brittle or brash.

Dynamically, these headphones can take changes in intensity in their stride. From the quieter drums and strings that rise up when the song begins to the hearty, husky tones of Lisa Gerrard’s idioglossia (her invented language) that fill the space, these headphones make smooth transitions allowing you to really become immersed in your music.
But while these headphones have an enjoyable sound, their rivals are a clear step ahead. The WH-1000XM3 (and newer WH-1000XM4) have an earthier bass and more insight, while the PX (and more recent PX7) have a better sense of rhythm and dynamics.
The QuietComfort 35 II are hugely effective in a Ronseal kind of way: the excellent noise-cancelling keeps everything around you quiet, and they're exceptionally comfortable. In those regards they're unbeatable, and for many a regular long-hauler, they'll be the most important factors.
But these Bose headphones aren't the best sounding of their ilk, with the Sonys in particular offering similar levels of noise-cancelling and comfort with an extra helping of musicality. They now support Google Assistant, too.
Still, if you're happy to sacrifice that last little bit of sonic ability in the name of added comfort, the Bose QuietComfort 35 II could well be the noise-cancellers for you.
