Indeed, it's really him higher, particularly associated with a dedicated amplifier (PH300 Shanling for me, so hybrid): just stamps votes present without excess, low for them (not so boomy), acute realistic spatialization ... is also one of the big strengths of this helmet ...
Currently abroad, I can not buy hifi quality system as in France, but this lack is filled largely by the acquisition of this helmet ... now, this is the amp-speaker system that will have to be at the height of the helmet system ...
If you want better, we have to "ante up", take the high-end amp that both headphones (Stax, Denon Hdg, etc ...) So ... go!
