The Triples were one of my earlier "audiophile" purchases, and one of the few from that period that I still like and use regularly. I think they sound great and deserve the praise they receive (can't speak to the mic, as I don't use it). My only mild complaint was that the tips didn't really work that well for me, comfort and isolation-wise, but that's a personal thing. They still sounded great, though, and I was recently able to fix the fit issue with some tips from a set of BrainWavs IEMs in an MD Blue Box that I didn't care for. So I can easily recommend them on their sound quality.
However, again speaking just to the Triples, I don't think this is one of the better deals MD has offered. This is the everyday price at Costco Online and you also get their outstanding return policy (granted, you need a membership) . They occasionally put them on sale with an instant rebate, where you can pick them up for $65. Amazon's regular price is close enough that it's not too hard to justify getting them in a couple days for a few dollars more. So, great headphones, mediocre price on this one.
