+ Surprisingly strong, relatively clean low end (in relation to the price). + The shape, as it presses directly on the whole ear, somehow creates a kind of "noise cancelling" (However, don't expect too much!). + Perfect for office calls / team meetings / Skype calls etc. as there is a microphone built into the headphones (and due to the aforementioned "noise cancelling" effect). - The mids are a little undercut (but the overall sound is absolutely fair). - No spatial sound but very "stereo" (very bad to recognise e.g. footsteps of opponents and to be able to assign them to a direction) - Relatively uncomfortable when worn on the ears for a long time (you feel the need to "ventilate" your ears in between) Conclusion: If you need headphones to listen to music or you want to wear them all the time, you should look at other headphones. For "office" purposes, however, the headphones are very well equipped.
