Nice job on the review, I had considered those a time or two in my last few runs of purchases but never did. Good to know about the cord too.
I've heard good about the HD555's too. I'm really enjoying my JVC's, the HARX700's and HADX3's. Recently started listening to the DX3's some more as they're a little more laid back but more detailed and comfortable. The 700's are in your face, tons of bass, but can wear on you after a few hours as far as comfort goes. I'm happy because both of them treat me really well and I'm at the point I have no need to buy anything else. Though between the two, the 700's get the most play time overall, I figure I'll give the DX3's a run for a while.
Again, nice review, looking forward to your future reviews! And to anyone else that feels like donating their 2 cents to this thread!
