Blissful. My fave tech purchase. Even with the manufacturing defect...

I love these headphones, the noise cancelling is pure bliss. Whether I'm on a plane, a train, walking through the street or mowing the lawn, putting these headphones on makes the stress of the world disappear. I love that the QC25s use AAA batteries, so when the power gets low I can swap the battery & be up & running immediately, no down time or remembering to charge them. I love that the cord is removable & can be replaced if you switch from iPhone to Android. The sound quality could be better (the high end is a bit dull, missing some of the lowest bass), but they're really enjoyable and comfortable to wear everywhere. And I use these while first building a song, when I want to have fun & not be analytical about the sound. I honestly can't be without these headphones, so much that I also own a backup pair in case one breaks.

And that's the catch: there is a manufacturing flaw in the left ear cup that causes the noise cancelling to stop working after a year of use. This is the third time I've had this problem. (Search for "Bose QC25 left ear" and note the results.) Thankfully Bose is usually gracious enough to give a free replacement the first time, and Bose have a policy to swap their products at-cost for any reason if you buy direct from them. But be aware, you could be paying every year to replace these things. As long as you're okay with that... wow, the noise cancelling & comfort makes these such a good purchase.

like the 35ii, but better. if only was wireless

take what i said about the bose QC 35ii, but with a hotswapable AAA battery. only gripe is no wireless, which on a pair of headphones which are more casual, is a bit of a dealbreaker, but outside that, a solid set. just DO NOT expect these to eb good for mixing/mastering. but for jsut a standard use headphone, they're pretty nice.

The Best noise canceling from headphones I ever experienced

The sound is always crisp and clear regardless to the noise canceling. They are very comfortable thanks to nicely padded ear cups and headband and light weight. The noise canceling "white noise" you usually get from noise canceling headphone is almost gone and can bearly be heard without music on; music on at a low volume is enough to eliminate all exterior (reasonably loud) sounds. I wear them every day on my morning commute to school and it easily blocks out the sound of screaming children. Would recommend. Worth every penny.

They are so good.

The Sound quality, the comfort and all the other tings of this headphones are so fking nice
