poor construction.

I made the purchase of this helmet ..2011 after a few days of his problem in the left lane ... looking that I covered
a slide potentiometer was defective! I have not been back to the seller, and put that helmet rebus. secondly the lack terribly medium and treble, one bass are dominant, no balance ... in the frequency spectrum.

I dug up this headset a few days ago and did some tests on my Archos MP3 player as well as a clip sensa and
my amp Nakamichi, despite using the impossible to have a sound equalizer with relief in the spectrum of frequencies. I recommend this product which proves poorly constructed.
the clamp head is also a concern, because after 1 hour of use ... evil around the ears.
piety for audiophile quality.
