The RE400 and the RE600 are extremely similar in sonic signature, and I had the RE600 but since the RE400 sounds almost the same, I decided to only keep the RE400 at half the price.
I love that these IEMs are so tiny and it's so easy to achieve a good seal. Almost all the tips provided work quite well (some better than others). There are almost no useless tips that just doesn't work at all for my ears, unlike all the other IEMs I've had in the past.
The sound is quite flat, and really inoffensive, so at the very least, it does no harm, which is my number one rule in audio. This in and of itself is something remarkable, because consumer electronics too often give us headphones that are too bright/shrill--to the point of being fatiguing, or have bloated muddy bass that's far too excessive and has no detail at all, or have really rolled off treble that sounds muffled and dull. The fact that I can listen to the RE400/600 without having to EQ them in order to get some semblance of accurate frequency response without excessive sibilance or ridiculously bombastic bass, makes them much more usable than many of the so-called TOTL (Top of The Line) flagship IEMS that cost well over a thousand dollars, and this is including some that are marketed as "for professional audio engineers to mix/master with."
But the RE400 and RE600 aren't actually totally flat--they simply seem that way compared to the exaggerated sound of typical IEMs. In reality, They are missing some high treble energy, lacking some presence in upper-mids, and the entire bass region is not substantial enough to be truly authoritative. They're basically what some would consider a "boring" sound that has no sparkle, no impact, and no richness either. If they are technically flat/neutral as some say they are, then they wouldn't be weak in those frequency regions. If you want to hear it for yourself, simply play sine wave test tones from 20Hz all the way to 10 KHz, and you'll hear how from 60Hz to mid-bass they're relatively weak, and how around 4KHz they're recessed to the point of sounding a bit muffled, and around 10~12KHz they don't have enough air.
At the price of roughly $199, the RE600 is not as bad in terms of value compared to before the price drop. At double the current price, its initial pricing was definitely way to high for this day and age when there's so much competition and better sounding products that are cheaper (of course, better being subjective). The RE400 at half the price of the RE600 is much better in terms of price vs performance. It's really quite a steal at only $80.
So basically, if I'm listening to just podcasts, I'd be okay with the RE400/600, but if I'm listening to music, I would need to EQ them to make them sound more dynamic and exciting. I can certainly listen to them with EQ, but they would sound a bit dull. I've included screenshots of my EQ settings for the RE600 and the RE400, for those of you who want to try it.

I was recommended these after I had some issues with my Xiaomi Hybrid IEMs. These look similar and were presumably of higher sound quality, and after getting them and using them for almost two months, I can say that I've come around to liking the overall sound. Less bass than my Hybrids, but some would describe the Hybrids as having too-prominent muddy bass (which I kind of agree with now that I'm more used to these 400as), so maybe this amount of bass isn't terrible. I'm definitely picking up more detail in my music, too.
I would give them a 4 or even a 5 based on sound, but I'm finding that the build quality isn't splendid, and it looks like other reviews have picked up on this too. As I mentioned before, I've only had these for two months, but the rubber part of the wire on the left side is coming undone close to the earbud and also close to where the left and right wires split. This is weird, b/c I haven't done anything with these I didn't do with the Hybrids: actually, I've done *less* with these, because I don't take them to the gym with me.
So, to recap, sound quality is pretty dang good, though missing a little bass. Build quality is shaky, and while I was thinking of maybe buying a second pair of these in case the wires fail on me, I think I'd rather go find something else.

Reference Grade Audiophile sound quality !!!!

I must say its like an in ear sennheiser HD 650. With just 32 Ohms impedance and 102 db SPL, it can be driven vitually out of any mobile device. If you have a DAP/Premium DAC device with output of 2Volts and above then its scales very well and then you can feel its Dynamic sweetness. I am running it straight out of my LG V40 and its just a treat to my ears.
I wonder how its going around at so cheap price and still many are criticising for its build quality, I defer though. Folks at this offer price there is no point in even touching other points for discusssion considering the sheer value it offers in terms of audio quality.
Ps note. This is stictly not for Dhamakadaar music lovers who prefer bassy and trebly sound sound characterstic as reference.
It you just love to listen and feel the soul of music what artist intented. Then give a no second thought. Just go for it.
Cheers!
