A good helmet, but not the best

The headset is quite correct, immediately recognized by Linux Ubuntu 14.04.
However, I would recommend taking the model above, the Logitech H800.
A reading of a test on the internet, I had thought that the only difference between H600 and H800 bluetooth support was more, but having experienced both, I can say it is not so: the H800 scope is much better.
If you stay in the same room OK but changing room, it is quite possible that the sound does not pass.
For sound quality, I have the impression that the H800 is a bit better, but I can not be sure because I bought it as a gift.
