Temporary owning AD 300.
Just wanna give some brief comments bout it.

Basically,it plays instrumental music very well.
It can handle Celion Dion and Kenny G so good that I think it's really worth the price.
But then I tested on Jacky Cheung on onboard audio,the vocal goes to background,probably it needs a better source?
Heavy bass tracks is a no no for this headphone.
I felt irritated after listening a very very short while to some modern songs that contain bass.
Boom until headache.
But the performance of bass is not that well for "Transformers" movie.
Can't still give the impact.
Overall,it still quite good for its price,even for the retail price.

@Akabane:Can bring collections over on gathering ah?haha..

Good good..
@DaEMoNteNTAcLe :Luckily that's just a test unit..
