I just bought this headphone at Thomann is trsdu ... I am not a pro but the I confess that this product is unusable. First, it does not shake at all on the head, the slightest movement and that it falls (not good when you do the battery). In addition the appearance trs seems fragile, we will see over time ..
The sound, although possdant a good dynamic, is quite deaf, prdominance of a low (think low down on your chain!).
My brother buy a headset Philips 30 euros in a supermarket, and this one sounds much better, with a comfort also suprieur! The ratio quality / price of T-bone is not good even then .... Go your way, really (me who wanted to buy micro battery of the same brand, I think I m refrain)
