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.
