I use it for 6 years is a good report quality price trs.
It's true it vibrating bass, treble are imprcis, trs is solid from which I had the same problem on every headphone that plastic ends up breaking to the ear, at least it's better (stronger than the level sennheiser rotten with their son that breaks after a month.

I recommend these headphones to listen all the sounds of the 80 type electronic.
