‘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

After good experiences with Beats (2 pairs), which were pretty fragile, I came home to Jesus with these Bose headphones. The noise-cancelling part is battery (AAA) powered, but everything else is just mechanical -- no need to charge the headphones themselves, which is a big improvement over my last...

My only gripe is the battery compartment....hard to open/ close the battery contact (spring) can be fragile and misaligned to conact the battery properly. Bose can do better!

Sound quality/ active noise cancel/ super comfort fit for extended periods

the mini jack that attaches to headphone can be fickle....slight movement can cause sound to disconnect/ reconnect with just slight movement. Battery compartment door is flimsy/ hard to open/ close battery contact (spring) can misalign

There seems to be a lot of issues with the sound quality for these 2nd gen Bose phones. These came out before wireless headphones were in any significant use, and when few other companies were making a serious attempt at noise reduction.

Very very good noise cancelling; Industry standard for their time

Not intended for the highest quality audio

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

I just tested this, together with 7 other kids. Must say directly, this is a fantastic handset! The only drawback is the cord. Actually. No, one more thing ... the sound without noise reduction is not funny ... murky and flat ... so it must be activated. Incidentally, the cruel!
