The RE line isn't accurate at all in the lower regions imo. Sure it might be neutral as far as frequency response, but the bass lacks the realism that is needed. This lack makes the reverb subpar and makes it sound overall thin. I usually use piano reference tracks and all of the REs make the piano sound thin and a bit edgy. The bass is there but it's thin even if the quantity is there. Due to their nature, IEMs need to have a nice hump to in lower regions to have realism imo
Totally agree. It's something that's lacking for the RE0, the RE-ZERO, and even the RE252. I do like that the RE-ZERO does have good dynamics and energy and can to a degree portray a decent amount of decay, definitely an improvement over the RE0. The RE252 offers an uncanny amount of note impact and does offer some level of decay, it to is a little lean in body. I think this is largely a side effect of these earphones operating with tiny, sealed enclosures. None of the designs for these offer a loose enough driver to really fill out the note. Hopefully the RE262 fixes this shortcoming, and what little impression exists with them, they seem to offer more bass presence. In the $200 price range, the RE252 is still the best option though.
If you want a heartier note, there are other eaprhones out there that will offer that. The Klipsch Custom 3 and UE Triple.Fi 10 readily come to mind, and both can be bought for under $200. I might also include Denon's C751 too here. However from a purely analytical standpoint, I would still lean someone mostly to the RE252. Despite the lean low frequencies, I feel the outstanding midrange and treble are well worth it and the excellent note impact and note speed on the low end does certainly help offset the lean body. They are however a little hard to fit in the ear given you have to both comfortably fit the gummy and tip. The best route is a foam tip like Comply T-500/TX-500 which offers a lot of compliance to let the gummy position comfortably in the ear and enough compliance left over to easily seal the ear canal. Part of the challenge to get a really good seal with these things does make a lot of user probably rarely hear a well sealed impression of these earphones, or if they do, probably not comfortably. Do it right, and you're rewarded with a lot better low end presence and good comfort.
I want to toss in the very classic king of them all, the ER4S. Since this can be bought new for under $200, the ER4S should never be overlooked when accurate reproduction is sought. There is a reason why this still exists and is still highly regarded even after +15 years of competition.
