I use them for years. Overall excellent headphones. Strong deep bass, but muddy and not clear enough highs. And not loud enough. For 16 ohm headphones this are pretty quiet headphones. But the noice canceling is pretty good. They fit nice in the ear canal and dump the outer noice quite well.

Over the years I have had multiple headphones, some were good, and not so good. I find that a lot of headphones on the market have either too much bass or too much treble. Not these. When I purchased these headphones, I was really surprised how balanced they were in sound quality. All frequencies are evenly distributed, which exactly I was looking for, as I prefer to listen to music which is close to the actual source in sound rather than having it boom in your ears or too much pitch. These actually are close in sound quality to high end studio headphones! and they dont distort on high volumes. I use these for sound editing for retail music and never went back. The only downside of these as they do break easily, so extra care is needed, however for the price, you cant complain.

I bought this a month ago and it is really great. I am happy I bought this.
