Bose Noise Cancelling Headphones 700 review: great for calls, pretty great for music

Bose NC 700 are among the very best noise cancelling headphones you can buy. But they ain't the best.

They may have one of the most hilariously prosaic product names ever, but Bose Noise Cancelling Headphones 700 – or NC 700 if you are short of time – is a BIG DEAL in the world of headphones and definitely one of the best noise cancelling headphones you can buy. Bose's previous over-ear noise cancelling headphones, QuietComfort 35 II, didn't just sell like extremely hot cakes that you can listen to music through, they defined a new and lucrative market for Bluetooth wireless headphones with highly advanced active noise cancelling. And highly lucrative, premium price tags.

I got my hands and indeed my ears on with Bose Noise Cancelling 700 and while they're not a big leap forward in terms of music playback over the QC35 II, they do look and sound very pleasing and have one hugely impressive trick that no other ANC headphone can match. Is it enough to overtake the Sony WH-1000XM3 in terms of quality? Bose will probably wipe the floor with it, if we're talking sales. 

Bose Noise Cancelling Headphones 700: sound

You can say whatever you like about this guy; he won't be able to hear you… (Unless he's on 'Conversation Mode')

The noise-cancelling on the old Bose QuietComfort 35 II was absolutely jaw-dropping when it launched back in 2016. Since then the likes of Sony WH1000XM3, Beats by Dr Dre Studio 3 Wireless and Bowers & Wilkins PX have arguably made improvements over the Bose NC – but not by much. 

Suffice to say, the noise cancelling on Bose Noise Cancelling 700 when listening to music is very good indeed… but not really that much better than the QC35 II. It's hard to see how it could be significantly better; the bar was set so high.

Noise cancelling when making calls or using any other voice service (Alexa and Google Assistant can be activated by voice alone; Siri with a button press) is another matter. These headphones don't just let you hear what others are saying by removing background noise at your end, they also make you easier to hear at the other end, or by your virtual PA of choice. 

With people making more video calls and using more virtual assistants – and even voice calls having a resurgence, apparently – Bose reckons this is the USP that will propel Noise Cancelling 700 headphones to the mega bucks, just like QC35 II. 

Audio performance overall is really good. Noise cancelling can be dialled from zero, with audio pass-through ('Conversation Mode') all the way up to a cocoon-like 10. You can also choose your three favourite settings (0, 5 and 10 presumably, for most folks) and toggle between them with the press of an ear-cup button.

The quality of audio you get from these Bose headphones has a slightly unearthly, pristine quality to it, especially with the NC full on. You can't really say it sounds 'natural', cos it isn't, but it sounds very pleasing indeed. The performance seems less driving than Bose's big rival, Sony's WH-1000XM3, it's more of a smooth, measured sound that you could probably listen to for hours whilst on a long-haul flight or all day at work, so you needn't ever speak to your colleagues. 

Bose Noise Cancelling 700: battery life and design

Your colour choice: silver or black. How surprising!

Bose Noise Cancelling Headphones 700 battery life is quoted at a comfortable 20 hours. You can plug in a cable after that, although you can't use the noise cancelling when wired.

These look and feel better than the QC35 II, I reckon. They have a less bland appearance and seemed even more comfortable – although given the short period of use I got with them, that is very much an initial finding. 

The Noise Cancelling 700 don't fold down in the same way as the QC35 but the earcups can be slid up their stems to make a fairly small package, and the case provided is slimmer and more compact than on Bose's previous headphones. Seriously, who uses those cases though? I literally never have.

In traditional silver-grey or black there is nothing exciting as such about the look of Bose Noise Cancelling 700, but they are contemporary, tasteful, well machined and comfortable – what more could one want? 

Controlling volume and track selection with taps and swipes on the left earcup wouldn't be my first choice, but it seemed to work well enough. Buttons handle power, voice assistants and NC level setting.

Following a smash hit like the QuietComfort 35 II is no easy task, but Bose has made a great job of it here. When it comes to listening to music I'm not convinced there's necessarily a compelling reason to upgrade, though they certainly don't disappoint in that department. 

For anyone who makes a lot of calls or is an enthusiastic user of voice assistants, this does seem like a big leap forward – the way the Noise Cancelling 700 improves the perceived clarity of your voice, as well as removing noise from what you're hearing, is really quite magical. It may even mean an end to you having to bellow, red-faced  at Alexa, Assistant or Siri because it's once again started playing It's Raining Men by The Weathergirls, when all you wanted was a weather update. That's worth 350 quid of anyone's money.
