Love the noise cancelling -- the sound of the big air conditioner next to my back deck was GONE

i use it primarily for the noise cancellation but i do enjoy the good sound quality as well.

Great sound and noise cancelling ability.

The sound is exceptional as is the noise blocking

They aren't quite as loud as the beats I owned previously but because of the noise cancellation the sound was better.

These do a great job of blocking out sound.

I rate the sound, design and ease of use better than the QC15's, not to say that the QC15's are bad, but if you don't mind the weaker bass and u dig the absolute crisp and clarity in a headphone and use it mostly for traveling or at

If you want excellent sound, Bose can not be beat.

For a casual music listener as myself, the great sound, compact size, out-of-this-world noise cancelling, and sexy look make this a must-have pair of headphones

When sound canceling is turned on they're fantastic but once the battery starts to die the headphone sounds begins cutting out erratically

The sound is remarkable , clear and crisp, the bass tones is just as rich

Good sound though.

If the battery has lost any charge at all, I lose sound from one side

I am really into great quality sound

The sound is so great that together with the noise blocking it is like you are transported and the world has disappeared around you.

After owning the simpler Bose headphones (OE), I tried the newer version (OE2) and found that whenever I moved the connection cable at the point of connection with the headphone jack there was an unpleasant hissing sound; this finding was true to three difference sets (all black; there is a chance the white set does not suffer from this problem, but I haven't investigated the matter personally).So, I decided to upgrade to the quiet comfort 3, finding their packaging, layout in packaging (meaning the way they fold), weight, general feel and cable quality similar to my old OE pair

I love the sound, the cord is long, the earphones themselves are super

The sound was great but the build was crap.

Great sound, lightweight.

Inflated price, too loose for sports, no bluetooth, fall off when bending over, leaks sound a little, easy to forget to turn off, need to recharge and change battery

The sounds is good; it is a very light and comfortable head set

You get crisp, clean sound while maintaining a very controlled accoustic bass that imo sounds better than the QC15's

To me the sound is perfect

Good sound and very comfortable.

Great sound

I can still hear the spinning DVD drive of my notebook, the sounds of clicking keys as I type as well as the clicks and scrolling sounds from my mouse

QC's may not have the clairty and surround like the QC15's, but it's an on ear headphone and has a better bass response and well balanced sound, which is perfect for myself personally

Can't see the point in listening to the (admittedly beautiful) sound of music *as well as* the unwanted voices

Pros: great sound & very comfortableCons: these don't work without battery (risk to have it discharged, lose it & so on), the microphone "listen" to everything

Love the sound

With that said - These are the best sound for non-can headphones on the market.

Especially the high end sounds dull and muted
