After 5 months or so the leather on the ear part started ripping and now the sound goes out on one or the other ear phones sometime both!

Noise canceling works great and they sound good.the soft leather covers on the ear cups fell apart after 6 months

The leather round the ear cup inside started ripping just after 6 month i bought it, i tried all means to call the company for the guarantee but not avail

The over ear cuffs are a plush leather, but inside the ear cuffs is a cheap fabric

I had a pair of the Bose, but the faux leather have started to flake and it makes wearing them on a plane embarrassing due to the little black flaking left on my ears..yikes!

How, after a year of moderate use, the faux leather on the headphones began to rip at the stitching followed by cracks in the faux leather as well

They are great headphones but within a year of having them the fake leather covering the ear pieces started to separate... not something you would expect through normal use within a year for such expensive headphones.

The leather on the headphones already started to rip and on one of the headphones, the sounds goes away

Poor leather quality,starting to fall apart with normal use

Cheap leather around earpiece

After using them for 6 months, the Right leather over ear piece fell off

After using them for 6 months, the Right leather over ear piece fell off

The price is, as you can see, too expensive to be bought when you aren't using it often

Bass is hard hitting, but not as annoying as in the QC15

And the mods and highs were not nearly as crisp as you should have from a pair of $300 headphones

They do not perform nearly as well as at least two other over the ear headphones that I have owned.

It doesn't bother me as I can hear it only when there is no music or video playing
