Sound quality, to my preference these are 5 stars.
Just this side of warm, with strong bass, forward mids, and extended treble, without being fatiguing at all. This must be the syrupy warmth people talk about.
I run these off my Sony NWA45b without problem, and they handle all my genres without issue.
Be sure to try out the different filters! I tried the stock and bass filters, and hated it. WAY TOO BASS HEAVY FOR ME. I put in the silver filters, and things just clicked, in the best way.
That said! Here's why they lost a star:
I love the look, the cables, and everything, nothing wrong there. But the filter threads aren't the tightest. My silver filters keep backing out after the lightest of use (sitting at a coffee shop table, listening to music, and taking them out on the occasion to hit the bathroom or buy more coffee). I almost lost the filters twice, once when just opening up my carrying case, and once when taking the DMG's out of my ears. Now that I know, I'm pretty vigilant about retightening them. Still, a worthwhile inconvenience for the best sound I've gotten out of an IEM for under $300 so far.
