- The compression headband too tight, and suddenly heavily on the ears, so it hurts after a while (an hour and it gets unbearable, you have to pause). I thought it would tend to relax with months, nay. I think I'll loosen it by forcing in the opposite direction, at the risk of damaging it :(
- The cable is not detachable and ca may sound stupid, but it's quite a detail that counts: 3 METRES therefore it mean never leaving home obviously (!). I wish a long cable to the living room, and a short cable for the metro. Bundled AC would have been even better;)
- I did not know the form of "open" in the helmet, I admit that I bought without knowing. A priori, this provides a more natural, and we must admit that the result is up, but hey, everyone actually enjoys. If you turn the volume a bit much, no doubt that all open space / TGV / family / etc with you hear your music / film / series / etc
- I still am not to this plastic strip taupe. It's just like a detail, but I wish the leather.
