Well, after about 12 hours of pink noise burn-in (on real 630s), heres a non-audiophile mini-review:
Fit: Very small and low profile, especially when worn a la shure. I find it very comfortable, even for sleeping. It is closed, comes with three different sized tips, and is easy to tell when you have a good seal, which I like. The isolation is good, I think it is good enough for planes. I made my own sincher to secure the wires more, and this with wearing them over your ear virtually eliminates the originally terrible microphonics.
Sound: Out of the box, the
highs were very harsh and I could not listen to "All Along the Watchtower" by hendrix because it was a little painful. However, after 12 hours of burn-in, the change is dramatic. Highs are now calmed down and much more detailed, comparable to those of um1s. Watchtower now sounds crisp and bright, much better than marshmallows.
The
mids are only a little bit muddied. They don't have a strong punch but are very satisfying. Plenty good for rock IMO.
The
bass is where these things accel. Out of the box, it was heavy, bloated, and slow. However, after burn-in, it is accurate, tight, fast, and still powerful. These are now my go-to phones for trance. They also make rock very satisfying.
Overall: I would describe these as closed, more up-front Vibes. They are very "fun" phones for all types of music while still being relatively neutral. They are definitely not analytical, but more for casual listening. For 30$, I would definitely favor them over marshmallows and if you want isolation and to save some money, these are great over vibes. Suggestions: definitely burn-in with pink noise, I like them worn a la shure for comfort and microphonics, a home-made sincher makes them more secure, and buy them from a trusted dealer, I have heard lots of stories of fakes.
enjoy!
