Finally the helmet I wanted.

Purpose of purchase: Good reasonably priced helmet adapted to wearing glasses.
My old closed headphones (s * st ** lseries beria) too crowded on the branches of my glasses causing discomfort and little headaches.

Sound:
Very good sound quality headphones which surprised me!
The balance between low (deep) and treble (bright without being garish) is ideal for a small open headphones of this type and I'm surprised to rediscover some songs.
In games (main activity) the sound is very clear, we hear every sonic detail, the background music is very well done and very well mean the voices of other players.

Materials:
Quality workmanship, the headset is very lightweight plastic.
It hardly feels and pressure on the ears is very low.
Disadvantage, the helmet moves if for example the head is leaning but in my case, the effect was sought.
The helmet covers just the ear, without pressing on it and suddenly, absolutely not bother me with my glasses.

I have read many reviews on the cable. True, he is not big but not super late.
I would say that anyone a little careful should have no problem with the sustainability of this cable but a somewhat brutal child could break it quickly enough (as many other things besides).
The son at the jacks are not thinner than s * st ** lseries beria for example.
By cons they concervent the same diameter everywhere (about 2mm), including at the level of the order and the headset which can parraître more fragile.

Micro:
My friends hear me very well, as well as with good closed style headphones lseries s * st ** beria.
I like the little foam to put your microphone and the fact that it is placed conveniently on the side of the mouth, allowing for example to drink without moving the microphone.

Summary:
I found the helmet I wanted. Suitable for glasses (finally!), Light, very good sound quality and at a price I believe unbeatable for this quality.
Recommended.
