Practical and holds up well

We regret several things:
- The manual that is not translated into French. It's too bad, although I managed to get along without
- The cover to connect the USB to recharge is difficult to remove, luckily I nails. Gene and a little connection. (But not insurmountable)

I was not really convinced but ultimately, it is very easy to use and, essentially, take the headphones very well in the ears (this is THE main point for me)

The sound is good, the equipment with my phone was done quickly and simply.

I even got to run with without having to replace every two minutes so perfect!
