Right now i use it w/ my Westone UM2's and heck, even the stock apple buds sound much better with it, but the real reason i bought it was for when i buy my Grado SR60 or SR85's.

The amp was $40, Cable was $17

NICE! I want one. Where did you get it? I'll skip the cable. You didn't buy all the parts for $40 and built it yourself did you?

I've always wanted to make one for my Sennheiser 580s but I never got around to it.
Maybe I should just buy one...

Do you know how long the battery lasts on it?

Yeah, ive been soldering for al ong time, skill only improves with time my friend, and NEVER try to do hardmods on a voltage chip on a vid card/mobo etc if you dont have expereince with stuff that small...great way to fry a card...

oh, i thought you made it. Making a PPAv2 now :D
Although, btw, the SR60 doesn't really need an amp and there is no such thing as the SR85 ;)

I actually thought about building these and selling them on ebay for a little extra money on the side, but I never got around to it.

Nice buy and good luck on your first build :)
