The Bose QuietComfort 25 are once again the ultimate headphones from Bose for exceptional sound quality and noise cancellation

Before there was Beats, there was Bose. The QuietComfort line is the original über-popular headphone line, even if it's aimed more at business travelers than teenagers and celebrities.

Powerful lows and crisp, bright highs with no distortion at top volumes; Exceedingly comfortable; Best noise-cancellation technology available; Can be used as passive headphones without power

Runs on a AAA battery rather than a built-in, rechargeable option; Sculpted sound signature is not for purists; No auto-off function

If there's one company that tends to do well in the field of noise cancellation, it's Bose. We've seen its headphones used by so many on overseas trips, and now we're about to see a new model on the heads of people who love sound, with the highly portable QC25i.

Battery lasts around 30 or so hours; Balanced sound; Headphones work when there's no power; Remote works for iProducts; Highly portable; Comes with a nice case

Cable ends in 2.5mm jack; Noise cancellation mics on the inside don't lend themselves well to excess vibration; Headphones could have more volume

Bose has long been recognised as a company that has both produced very stylish headphones/speaker systems, but not always had the backing of real audio lovers. I have to say that I have never been a person who could spend anything over £100 of my own money on headphones for my iPhone/Android or...

I'm not a big fan of wireless headsets apart from a few exceptions and this review will portray exactly why I feel that way. Let's just cut to the chase, The Bose QuietComfort 25 is probably the best noise cancellation headphones I have ever used.

The QuietComfort 25 (QC25) is the latest model to join Bose's massively popular noise-canceling headphone lineup; it replaces the QuietComfort 15, the best noise-canceling headphone I've heard, till now.Weighing just 6.9 ounces, the QC25 is one of the lightest full-size models on the market, and its...

The best noise-canceler; period; Headphones can play after batteries are drained; Light and very comfortable

Sound quality isn't stellar

"The QC25 widens Bose's significant lead in noise-canceling technology, though it trails some other competitive 'phones on sound quality."

The best noise-canceler; period; Headphones can play after batteries are drained; Light and very comfortable

Sound quality isn't stellar

The sound quality doesn't leave to be desired. It's not perfect, but it's not far from it either. I admire how Bose is reaching for true sounds while still being fun and engaging. I hope that Bose continues to push the limit and make improvements to get closer to that perfect sound.

If you're wondering how much better the QuietComfort 25 than the QuietComfort 15 , the model it replaces, that's hard to quantify. But one thing is certain: it is better. While the two models bear a strong familial resemblance, Bose says the QC25 headphones -- which cost $300 in the US, £270 in the...

Extra-comfortable design; clearer, more dynamic sound; highly effective noise-canceling circuitry that's been slightly improved; new folding design allows the headphones to fit in a smaller carrying case; if the battery dies, the music now doesn't die; 21- to 30-day risk-free home trial

Fairly pricey

Four hours into my flight and the faint hum of the plane's engine sounds more like a roar. It's not the sound that's driving me mad, but rather the feeling it will never stop. Ever.

Active noise cancelling; Lightweight; Comfortable; Nice carry case
