Thru some good high recommendations I purchased a pair of Phillips Open HD headphones and they sound amazing, and with my closed Senn Pro HD 280 phons I now have the best of both worlds for playing and recording....

Update on the AKG K553 Studio phones I got from Musicians Friend. I've been using them with my BK9 and even the bass pedals with my organ setup sound good. And I have them EQed for a big bottom sound, I like strong bass.
As for my FP90 Piano even though I have it plugged into my studio PA I've been playing it thru its onboard speakers alone and have been very happy, and I'm a guy who hated onboard speakers. So last night I tried the headphones with the FP90 Whoa !, I actually stopped playing and though I had the PA on. Amazing clarity. Played for another 1 1/2 hours. I may not be using my studio PA much anymore.
This morning I decided I wanted another pair, one for each keyboard, if I could get them for the same Stupid Deal price. Called Musicians Friend and after the salesperson checked he said they would sell me another pair at the Stupid DOD price which was 50% off. Nice.

Congrats Bill. If you don't ask, the answer is NO.
