Audio Technica m-50 sounds about right for what you're looking for.

IMO the HD 25 sound good even unamped. I used to carry around the mini3 and i felt it sounded a bit better but I ended up selling the mini3 anyways. The size of the e6 is just so appealing for its portability. A lot less obtrusive than the mini3 or any other cmoys.   Quote:  

thank you and entered.

would the e6 be a good match with my clip+ and hd25?

AD700s are open, so there will be leakage and you will end up disturbing your roommate. Sony v6 are good closed cans that go for under 50 if you can find them refurbed.

Might want to give the HD25's a try.

Fiio e5. Use the bass boost feature. Small and portable also seems to be what you're looking for.

+1 on the E7/E9. Especially since you'll be going away from home. They sound great on my laptop with the dt880s.

If price isn't a big issue then definitely get the hd25. Also a big plus if you're going portable. I find the hd25 to be a lot of fun and very easy to listen to. The M50 are a little more laid back.   Quote:  

LCD-2 is way out of your range as well and should definitely be taken off your list. You may want to try Beyers, dt770 and 990 are known to have good bass.    

I've tried the the e9 and the mini3 on hd 600s and 650s. The e9 works better but like a poster above mentioned, they are far from portable. To answer the op's question, yes the mini3 will drive the 600s decently but not to it's full potential. Still they sounded pretty good to me. If you MUST...

Amazon currently has the e9 new for $92. Seems like a steal at this price.   http://www.amazon.com/FiiO-Desktop-Headphone-Amplifier-Dock/dp/B004M172FY/ref=sr_1_1?ie=UTF8&qid=1311983887&sr=8-1

Thanks guys, I indeed have the 250 ohm premium version, I confirmed with the seller and he offered me a refund.
