Yep, very useful - I didn't even know you could remove the back like that.
Hmm. I think my HD 650's are addictive. Over time it does almost seem like they're sounding better. Probably more psychological adaption than burn-in though, but who knows. Hmm... I should buy another HD 650 and do a double-blind :) (nah I'm not that wasteful with my money... yet).
Also, I don't know how people can call them veiled. I was watching Tron Legacy blu-ray (great quality sound, sounds perfect on HD 650s), and really high tones like glass/metal clinking together for example sounds stunningly crystal clear. Maybe what people refer to is the boosted mid-bass, which perhaps distracts some people too much?
