Positives:
These headphones are lightweight and very comfortable to sit but firmly. In bed / on the sofa you can put your head on the side without it hurts and you would regret it after 3 minutes.
The outside noise coming through quite well, so that one out yet everything will notice the bike or.
The bass is very good for this price range, but nothing beats the fans.
Negatives:
The treble sounds are in my eyes (or rather ears) very correctly pointed out. Some tones do not just hurt, even at low volume and can not even be wegbekommen with an equalizer. Very strong one notices the example of The Black Eyed Peas - Do not Phunk with My Heart or Beyoncé - Diva. The borders then already to injury.
Unfortunately, this is also a KO: criterion for me, so these headphones to land on the shelf.
