A good headset but ...

Accustomed to the headphones of 30 euros, I decided to invest in a good headset to hear the difference and unfortunately, in terms of sound I have not found a striking difference with my old helmet. It is too neutral cleaner but I found it lacked pizzazz.
Similarly, the headset is imposing and heavy, despite the fact that the foams are very comfortable, when considering one feels the weight.
The basic insulation is good but the noise system is not very efficient, it is possible to have a conversation with the system is activated and an activated music (even if it is still attenuated). Although we hear a slight hum when the system works.
The big highlight of this headset is its technology, including the high quality bluetooth as well as multiple commands to remotely control its issuer. Similarly, the fact that it is a battery and not batteries, and moreover of autonomy is very significant. But I still plans to return, hoping to find a helmet that is right for me in terms of sound.
