Update: I got to play around with them for around three hours this afternoon. Played through the entirety of the aforementioned Headhunters, then I ran through Led Zeppelin I, which is a 16 bit flac rip from the original '87 Atlantic CD. Obviously those records aren't the most well mastered albums available, so while the DM6s definitely shone a light on its imperfections, it also brought to light some of the micro details in Plant's vocal performance (tiny breaths I've never heard before, as well as background wails that sound so distant it's no wonder I've never picked up on them), and Bonham's cymbal crashes sound spectacular. After that, I kind of went berserk. I never liked the way my T2s played back my Deathcore albums, as the vocals always felt like they were buried in the mix. With the DM6s, the vocals sounded clearer than I've ever heard them in my life. Keep in mind, these recordings are brickwalled to hell, but still, I was really impressed (Suicide Silence - No Pity For A Coward, Whitechapel - Reprogrammed To Hate, and Winds Of Plague - Classic Struggle). Then I hopped onto Dr. Dre's 2001 album and blew through half the record, finding new things hanging in the background of songs I've heard hundreds of times before. After that, I was onto Eminem's Relapse and that's where I started to see where sibilance would be an issue for some. Granted, his vocal performance, as well as the album's mixing, puts a really strong emphasis on the "sh," "ch," and "tion" sounds in his lyrics, and due to his wordplay and alliteration throughout the record, it's probably more pronounced than on any other vocal-centric album I own. Still, while it was noticeable, it wasn't something I considered fatiguing, so my ears might not be as sensitive as others. Like I said above, I'm still figuring this out as I go along. What I love most of all, however, is the form factor of these little guys. While I always enjoyed the sound of the T2s, the way they fit in my ear always felt unnatural, and my ear canal always got unbearably itchy after an hour, give or take. Like I said above, I went for just under three hours when I took them out of the box, and while my ear was a little sore from adjusting to this new thing I shoved into my head, I felt no discomfort, and I never once felt like they were about to fall out of my ears, which was a common thing with my T2s. I know some of this is still new-toy-excitement, but given the polarizing nature of these iems, I'm glad it's starting off strong. Hopefully it only improves from here.
