I can say with little doubt that the driver is the best dynamic driver I've listened to in an earphone so far. I'm a fan of Denon's C700 driver, super efficient, really articulate, but poorly controlled and distorted at volume. I'm a fan of the long throw IE8 driver, awesome bass, high output, sort of like the XBL^2 of the IEM world, but it lacks speed and softens the edge. For a dynamic, the RE262 just seems to spank everything else out there. It's effortless, clean, doesn't really have noticeable compression, it gets damn loud and is happy about it.
It pretty much makes the RE252 driver sound like crap, haha, and that says a lot. The sound that is emitted is basically pure. It's something I haven't really heard from dynamic earphones, only great home audio drivers.
So how good is the RE262? Ha, well, let's see... I have a RE-ZERO, UM3X, Triple.Fi 10, e-Q7, CK100, RE252, and my OK1 buds sitting in front of me. Referencing a little Jay Z, the RE262's like show me what you got? They have zero problem matching them. The RE262 is a top level earphone.
It literally puts the RE252 a half step down now. The coloration may or may not suit you, but this might be a simple matter of EQing. What you end up buying is always dependent on personal preference. I can only state that the RE262 is good, exceptionally good. The driver is outstanding. The physical form is of the value orientation that Fang seems to gear his products towards. It's no SE535, IE8, or e-Q7, but it is smartly done, and if sound is the main concern, then it's an excellent product. Is it the end all? Well, it's simply one of many options. My personal preference leans me more towards the CK100 for example as it is a more balanced device. However, I would be hard-pressed to call the RE262 less of an earphone sound wise. It'll just come down to personal preference though and what you main think about the coloration, which
is mild but there none the less. I can only say it's likable and that you do get used to it quickly. The RE262 is very transparent, visceral, but also non-fatiguing even at loud volumes. Low distortion tends to do that.
...but also the non-aggressive top end helps that too.
These are some incredibly cool earphones. I'm not trying to stoke the FOTM here, but yeah, anyone should really seriously look at these at some point along with any other high end IEM on the market. Yes, they'll stand toe to toe with any universal on the market. It'll simply be a matter of preference if the RE262 will be your best pick.
