I need the phones for my keyboar Roland E-300 (play at night)
So I tried the Creative EP 480 and I like the volume output, but in some notes they make noise. So I decide to buy a full size heaphones. I tried the Sony and the Pionneer, but in the both cases I have more volume in the ears with the Creative earphones. So I just make some reserche in the net, and I found that I must have a more SPL (sensibility) level, and I buy now the Sennheiser HD 202 (115 dB). But I dont know if the problem is resolve with that. So I decide participate with you my situation, helping yous sent to me same ansewers.
