Hmmm... seems like you need an open headphone to alternate with? Try out the AKG K612 PRO and some K702 pads. Its a safe choice at under $200 ($165 at razordog using coupon K612PRO and $31 for the pads at AKG parts).
Don't want the wife getting too jealous... but the HP50 might
I'd second that.
Pads notwithstanding in my case but,,, I am just happier with the stock ones [all ears hear differently :D]
I'd add the MA900 for consideration too :]
