Yeah. The response isn't as flat as some earphones. This isn't bad, but coloration tends to make an earphone favor certain music types. A very neutral earphone is a jack of all trades. A colored earphone specializes, although the specialization is kind of dependent on the person/people involved in deciding the coloration and its goals. To describe the coloration of the RE262 would be to say that a softer (not less detailed) top end was chosen, less sparkly, less piercing, a warmer sense. As well midbass and lower mids were also emphasized slightly, giving a warmer sense and a little more punch and fullness of vocals and emphasis of things like guitars/strings, and higher frequency drums. What kind of gets traded off is some air and sparkle to the top end. Things like cymbals don't crash and shine as much. Deep bass is lessened which gives you less visceral, deep, shaking bass, but you have more higher bass which offers edginess and punch to the notes. They hit harder but reverberate less which gives a little less fullness. Your focus goes more towards vocals, guitars, and a lot of common instruments that reside mostly in the midrange. For example, vocals and guitars are slightly dominant with these earphones. Cymbals, triangles, and any other high frequency instruments will be quieter and warmer. The bottom end isn't actually bad on these. They do extend very well and retain good output, but the emphasis is in the higher bass. Now my set is Hero Kid's set and and the bottom end might actually still loosen more and fill out. These are 150ohm earphones, and while surprisingly efficient for this ohm load, they still really need to be amped and pushed to get fully loosened up, especially since the driver used seems to actually offer a very decent amount of linear throw.
So what about the foam mod? Well, I think Fang was thinking ahead on this one. With the foam removed, the top end does open up some and you get a little more sparkle up top. It's still mild but more even. It kind of seems these were set more so with the foam removed and then added as usual for the end user to decide what they want for the top end. After have trying with and without, I do suggest without. It just comes out more even. It's not even close to the aggressiveness of the RE252 up top, but it does sound more balanced overall and with that little bit of sparkle that really should be there. Frankly I say bye bye to the foam because nothing bad comes from doing so with these.
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.
