The clamp does loosen a bit over time, without loosening them over books I've found they're fine after a while.
I let my friend try them in the car and I didn't hear anything on the outside. Definitely able to be used portable.
I agree 100% with the soundstage, very nice presentation and width.
That was me that said they are basically Ad900 with better bass. Glad you also agree!
Glad you're enjoying them, especially coming from the D7000!
Hey do these respond well to EQu app on ipod do you think? I like clear and slightly foward midrange and vocals and dislike overpowering bass(like the ath-m50s are).
