"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.

The QuietComfort 25 model takes Bose's already stellar noise-canceling headphones and levels them up to new heights.

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

Interchangeable - not rechargeable - battery

‘If it ain't broke, don't fix it.' We can imagine that came up when Bose's suits were mind-mapping the successors of QuietComfort 15s, which were the market's go-to noise-cancelling headphones for yonks.

Ever since Dr. Amar Bose had the idea for noise canceling headphones in 1978, the company has done research on techniques to make it possible.

Very comfortable and convenient to carry with you wherever you go

The remote control only works with Apple products

Upgraded from the QC15 about two (2) years back, mainly because you could turn the noise cancellation on/off. The sound quality wasn't all that much better, and at times I've also felt as if the QC15 was slightly better.

Great Noise Cancellation; comfortable

Not Durable; flimsy; noise leak

The Bose QuietComfort 25 are active noise-cancellation headphones. Not only are they superb at eliminating the low-register noise that is the bedrock of any city soundscape, but they also cut out the frequencies that tend to trample all over your music, often resulting in you having to turn up the...

Higher-grade build than previous Bose sets; Excellent noise cancellation; Pleasant; big sound

Better sound quality available at the price; Easy to leave on accidentally

-I did a bit of review reading and found one of concern about too much bass. Initially I agreed, but like any quality sound product there is some setup of the devices. After connecting to my laptop and looking for the EQ, I made a few adjustments and these sound amazing!

-Works without a battery; Great sound quality; Great build quality; Great fit and comfortable to wear; Awesome noise cancellation

-Only one audio cord included; the QC15's included two; 1 for cell phone use and 1 for just audio -No 1/4in adapter

If you're a frequent flyer then you've probably already heard about the Bose QuietComfort 25 headphones, otherwise known as the QC25. They're renowned for being lightweight, comfy for long periods of wear and offer killer noise-cancellation that can mute the hum of a Boeing's jet engines.

Lightweight construction; comfortable fit for long periods of wear; outstanding noise-cancellation (ideal for frequent long-haul flyers); carry case included (with double 3.5mm aeroplane jack

Standard AAA battery (not rechargeable on-board battery); some noise-cancellation issues (doesn't seem to like trains much); sound quality poor when battery depletes
