Doesn't sound like your cup tea. You always have liked more bass.

my he-400s are almost on the way... just want to know about the rev2 vs rev3 thingy and where are they available?
The rev3 batch was sent out from Sept, 11th to Oct, 5th. You also look at the plastic support by taking off the ear pads, if this plastic is yellow, you have the rev3 HE-400 which have sibilant issues.
So there is a slim chance to have this revision now.

Still doesn't have the mids of the hd650.

So I'm going to visit family for about a week in just a few days. Can't really travel with the he400. After that it's hd650 and other orthos. Looks like I'll be taking a break from hp's for a week. 
A baby HD650 on the go.
The a pretty heady statement. Are those even in production anymore?

Interesting. I assume powered well by any portable player. Hmmm...
Well, too late for this trip but maybe next time.

They're only $15 at Amazon http://www.amazon.com/Koss-KSC75-Portable-Stereophone-Headphones/dp/B0006B486K/ref=sr_1_1?ie=UTF8&qid=1352991212&sr=8-1&keywords=koss+ksc75


i agree. the he-4 is a fantastic headphone, and is definitely underrated. its kind of a bummer that the 400 swooped in and took its thunder.
