Good points:
1 - It is not used too much head, unlike the previous model (Sennheiser PM80X Orange). With the above in about an hour I had great trouble in the ears when there is really painless.
2 - The thread is in 2 parts. This allows me to leave the party included remote control hanging on permanently armband. My scracth a cuff that I used to wrap the excess wire. Once the installation done, I do not ever touch, and unplugging I put the helmet aside.
The remote volume is super convenient as to change the volume, no need to take the phone out of standby mode.
For those with an MP3 clip attached to the shorts, the wire is long enough, for those who have a cuff, you must wrap the wire rab not to see the part of the wire with télécommmande (which is a pity in my opinion ).
3 - No false problem contact, the sound is nickel.
4 - the headset comes with a small carrying bag.
5 - it is resistant to perspiration
Negative points:
anything right now, I expect to see longer-term reliability.
