Upon opening the package, I notice that the son are much thinner than before. And I decided to make my first listen, and surprise, the sound is flat, without bass. I check the connections, but nothing to do, the sound is not good. There is no amplitude, any relief! It's almost bad.
As I bought a second pair for a family member, I do the test with the other pair and the verdict is the same!
What surprises me most is that the bass that was the strength of this model is catastrophic.
This helmet has nothing to do with its predecessor despite the fact he has the same name!
At which point I will order another helmet but a different brand this time.
Farewell EP 630, I liked you ...
Addendum of 12 May 2012:
My headphones are dead. I fell asleep with, and waking the right earphone net was cut in half! Never seen that! This confirms that this product is mediocre and definitely to avoid.
