i dont know whether it has. but the output of it is really LOW! as big as iphone.

1964V3 is a good choice. but its bass may not the bass you want, although its bass is good enough in BA.

the resulotion of se535....such a crap

no offical confirms

undetachable cable?

good price, isnt it?

Compared to se535.i would like to westone w4r, because of the balance.

I used to listen on my N95 8GB by using se535. sounds good but not as well as on AMP.

I wanna ask if ak100 perfroms well without AMP on my 1964v3. and i want to buy x1 which is a headphone of Philips. I mainly listen pop and rock. I would appreciate it

firstly, I have to say that the sound of er4 is pretty clear and clean, which is the biggest feature of er4, isn't it?  and instruments are performed well on it. but on contrary, the sound of man played by it doesn't catch my ears compared with shure se535. things would be better when er4p...
