While not a quantum leap forward over the QC35 IIs, the Bose Noise Cancelling Headphones 700 offers slightly better noise canceling, sound and call quality.

The Bose Noise Cancelling Headphones 700 are very comfortable, have excellent noise canceling and work really well as a headset for making calls; They sound better than the Quiet Comfort 35 II, are loaded with features, including the option for hands-free Alexa and Bose AR.

$50 to $100 more than their closest competitors; QuietComfort 35 II is slightly more comfortable; battery life isn't as good as the of some competitors; the accompanying mobile app isn't fully baked.

The Bose Noise Cancelling Headphones 700, the long-awaited successor to its QuietComfort 35 II models, have a lot to live up to. The QuietComfort series is almost 20 years old and is essentially the gold standard for active noise-canceling headphones, beloved by airline travelers and open-office residents the world over for their ability to block out a good chunk of external distractions. Simply put, the QC35s are a hard act to follow, and some people aren't going to like all the changes that Bose has made in creating this new successor headphone.

At £350, the Bose NC 700 headphones are more expensive than their immediate rivals and don't best them in terms of performance, either. However, audio quality is still very good, as is noise cancellation, plus they look great and feel comfortable on the head.

Very comfortable to wear; Very good noise cancellation; Easy to use app; Great looks

Not particularly portable; Lean audio character; 20 hours battery life is a bit low

Bose is no longer at the top of the noise cancelling headphone race, but the 700 is an excellent option with powerful ANC. However, Sony’s WH-1000XM3 has better overall audio, and arguably better noise cancellation -- all for $100 less. The 700 isn’t the best, but it’s still really damn good.

Outstanding noise cancellation; Better design than previous Bose models; Touch controls are easy to use; Super comfy; Impressive voice clarity in noisy places

Treble can be harsh at times; No EQ adjustment in the app; More expensive than some of the competition; Bose AR isn’t a compelling feature just yet

The market for headphones with active noise canceling is large and more and more manufacturers are moving into this segment. Bose came under pressure with the Quiet-Comfort series, not only from well-known manufacturers such as Sennheiser, Sony and Co.

Very good ANC; Very comfortable to wear; Noise minimization even during telephone calls; Connection with two devices possible

Bose AR is (still?) a gimmick; No cable with in-line microphone and remote control

Bose's top-of-the-line noise-canceling headphones are excellent, but their unique features might not be worth an extra $50 to you.

Sleek design and easy to use ; Top notch sound quality with excellent ; controllable noise cancellation ; Makes phone calls in noisy environments much easier to take

The price could be a turn-off

The wireless Bose Noise Cancelling Headphones 700 offer terrific audio performance, hands-free voice assistant access, and the best active noise cancellation you can buy.

Best-in-class noise cancellation and ambient listening mode; Excellent microphone clarity; Powerful bass depth; Comfortable.

Expensive; Sculpted audio not for purists; No EQ (yet).

The Bose NC 700 headphones serve up excellent levels of comfort, as well as impressive sound and noise cancellation. Though the Sony XM4 edge them out as our favourite wireless ANC over-ears, the Bose are a great-looking pair of headphones

Very comfortable; Very good noise cancellation; Easy to use app; Great looks; Neutral sounding character;

Can't fold; Audio could use a little more organisation; 20-hours battery not massive ;
