I bought these headphones Perixx stamped at the time of purchase because my old pair of Altec Lansing had let me. Flat cable, price, good feedback and the fact of already having a product Perixx (mouse) had decided me to buy them. I regret this purchase, the sound quality was not at the rendezvous, the rendering was flat and stifled. I tried to adjust the sound equalizer but with no real improvement.
These headphones are sleeping so since in their little black cases and zipped shell.
The visual and product name has changed since my purchase, the product may be of a different quality, who knows?
