Sound quality is definitely subjective, no doubt about that. I just prefer not to spend over $150 on any chifi stuff when there are other IEMs from the US that I'd prefer to have (campfire, empire ears, JH) with proven track record, warranty, etc). The DMG just tick a lot of boxes for a budget hybrid IEM. Musical, engaging, easy to drive, comfortable, aluminum shells (IIRC), removable cables and filters to tweak sound. I don't think they sound like trash though?
My personal preferences line up with hawaiibadboy (aka bad guy good audio on YT). So I prefer warm, bassy, musical, even dark sometimes - especially over flat and neutral. When he recommended them highly, I figured I'd check them out for a budget pair to have around. Not disappointed at all especially paired with the Hiby R3. My favorites are the Sony XB90EX, JVC fx850, and flare audio R2a (still blown away at the sound that comes out of such a tiny IEM)
I'd like to hear the DM5s but I won't pay 350 for them. Maybe they are worth it, I don't know. Guess I just mean it's hard to jump on a pricey IEM. At this point I have enough universals, I really want to get customs. But even that would be a tough choice to make. And I prefer dynamic drivers over BAs any day :)
