used less than 1 month on the advice of a salesperson in a shop of audio, which praised the sound quality.
Apart from intra-mark standards like Sony & co, I did not test others.
Many "different pads" to fit the ears, not bad.
Listening, huge disappointment! They wanted to reproduce the effect "Big's" dear to djeunz.Des low, too low. A bit of treble, and midrange too recessed.
Result: A violated its very unclear and jumbled.
Second disappointment, cable, despite its solid appearance, is not at all.
Third disappointment, the assembly of the atria and very weak. Glue that does not. Everything comes apart.
With experience, I can not redeem it, and I would not buy more product this brand, especially for the price and reputation pseudo-pro they are trying to marketers.
