You know, I was really tempted by these Purple Hearts. Super intrigued... And like many of you, I suffer from gear lust. I did order them, but I ultimately ended up canceling. Why? I already have several pair of headphones that I love, and even though I can find reasons to justify buying these, I'm choosing not to. Primarily 2 reasons for holding off:
1) the cable is not easily removed/replaced and it's 10 feet long. 99% of my listening is done from a device within 2 feet of me so this would always bother me. The 610's coming out soon have a replaceable cable, so I wouldn't be surprised if these weren't updated down the line as well...or maybe (not as likely) the 610 will be in a similar price range.
2) the headphones I have suit my needs just fine. that's not to say I can't convince myself to upgrade down the line, but I try to at least limit my purchases to things I genuinely feel I'll be happy with... And I know the fixed 10 foot cable would bug me as long as I own them.
Fixed cable is not the end of the world but when I already have several pair of headphones that I'm really happy with, seems silly to drop big bucks on another pair that have some basic flaw (even if the sound is amazing) that will always bug me. There'll be another one down the line with a replaceable cable I'm sure, or the 610 will fit the bill, or maybe I'll continue to be happy with what I have. Who knows! Anyway I hope they suit everyone's needs, they look amazing, hopefully they sound amazing.. Just sharing my perspective. Looking forward to reading what everyone thinks when they come out.
