Thank you, JC and Will.
I'll keep the Sennheiser HD6 in mind. Of course everything is subjective, that day, that song, how much sleep you got.
Previously, I bought 4 various sets (not including the HD6) and kept the HD 280 Pros. For me, they were/are awesome. The HD6s are rated a little higher (again, that's subjective), so might have been a good set to test also. I bet you do like them.
Eventually I'll get a 2nd set of something and will certainly check out the 6s. Thanks for the tip, Will!
