Its negative points:
- Plug & play is a little temperamental. A single USB port of my computer recognizes it instantly. In the other outlets, I am entitled to each connection to a software update and a reboot request to the sound through the headphones finally so (or so I adjusted manually, but in this case, it is not more plug and play ....).
- It is not that we forget a helmet when he was on the ears! It is heavy, not very comfortable (especially the arch not the shape of the head), the plastic padding heats ears. This feeling of discomfort is probably increased by the fact that I wear glasses, pressure headphones on the branches that I quickly badly behind the ears.
