Wow, that went fast. REALLY fast. I was number 3 just a couple of hours ago and it's done.
My only worry is if I will regret not grabbing two pairs. I got 2 pairs of the K553s. One pair for me @ work, and another pair for my partner, who knows nothing about headphones. I just hate seeing him listen to music on his laptop with a pair of $20 Sony plastic cans. The reason I hesitated is that he'll be mad about the K553s even (he doesn't like "expensive" presents), and with these I wasn't 100% how they will work with just his laptop. He listens to mostly jazz and orchestral music, so I think these would work better for him than the K553s, with the big open soundstage and all, but I didn't get a chance to ask how they would work just driven by a MacBook Pro. And I figured if he threw too much of a fit about new headphones then he would be ok with $120 (for the K553s) - he almost went for the ATH-M50x @ $99 when they were on Amazon. $199 would be too much.
As far as my personal use, I listen to some orchestral music, but not a ton, and mostly EDM/chill/etc. Not sure if these are ideal for that. I just hate missing out on a great deal. They look great, could make great gaming headphones if I can ever figure out a wireless setup for my PS4 that would let me use them (even though the SteelSeries wireless I have don't totally suck)...it's only a little bit of money, right?
