Pretty good maybe at office. At home is useless without subwoofer. With subwoofer at home sounds good. So if you are looking for quite ok sound at office maybe worth of considering T40 or Yamaha NX-50 (no bass and treblle asjustment). But at home sub is needed for rich sound. At my desktop pc T40 works perfectly clear and loudly with reduced bass and added sub.
Good NC, good comfort to wear for longer periods. BUT: sound quality (both nc and non nc mode) could be better. Lows are quite muddy. Too much mids. Lack of trebble. Must use equalizer to make them sound good. E.g B&O H2 sounds the way much better. So result is good if you are using them just for travels with NC. NC function is really good here.
Its hard to believe those cans can produce such nice, powerfull and colourfull sound keeping in mind their size and current price (597sek). Those ar not 100% natural sound (which I hate), mids are slightly reduced (but not so much as e.g Beats) so in result you can enjoy really nice soubd. As well those are most comfortable to wear (on ear type) from my experience. Bought 1 unit for myself and later took another one as present for my friend.
Bought one for myself. Was so satisfied so later bought another one for my mom. Nice and simple iron solution.
Great sound from such size system. Great sounds even FM radio. Bass and Treble adjustment also helps to find the comfortable solution to your ears. I would recommend this product to anyone who is looking for mini stereo system.

Have made some (~20) orders from 120 to 22000 swedish kronor - everything went well here. Satisfied with service. Keep going!
