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.

They broke within 2 days of little use and good treatment

Easy to conceal within clothing. Trusted company with a good 12 months warranty. It would have been nice to have a volume rocker button to control the volume level. Except that it's great! I would say medium bass but sound reproduction, audio clarity and fidelity on the microphone is also good.
