"I purchased a pair of these headphones from Oxford Street London as an upgrade from the previous bulkier version. My other pair of Bose headphones were falling apart and the new model had just come out and so I went out and purchased it. BEST DECISION OF MY LIFE.

It delivers.

Unbeatable noise cancelling

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

So when you consider that Bose has also improved ease of use, plus added a special version especially for use with Samsung Galaxy phones, yet still kept the price below $400, you can see why I'm happy to rave about them.

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 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.

When it comes to trusted audio equipment names, few match the reputation of industry stalwart Bose. Since the company first dipped its toes into the tranquil waters of noise-cancelling gear in 2000, it's over-ear QuietComfort headphone line has evolved to become recognized as some of the best in the...

I've been totally satisfied with my QC15s. Needed a second pair of NCs for long air trips, so I ordered the new QC25. EQ is a little different than the QC15, a bit brighter, seems to have a little more definition. Listener EQ preference is very personal, but I like it.

Gave this to bf as a Valentine's+Birthday present, he loves it. The sound is great! The headphones feel slightly snug when music is not on, but once the music comes on, the headphone works perfect. It will be great for traveling. It was rated the best noise cancellation headphones by CNET.

Bose Quiet Comfort 25 gives amazing comfort and superb active noise cancellation but fails to provide that $300 sound performance. Not worth buying.

Lot of comfort Terrifying noise cancellation Very light weight

Mediocre sound quality Sound quality is rock bottom when noise cancellation is off Feels very cheap physically
