Unfortunately, I find these to be the most overrated iems going on the market at present. Anybody who claims that these have sufficient bass response are just deluding themselves, or others. They are extremely bass shy, to the point where it just ruins the music. I also own the Trinity Deltas, Vsonics vsd3s, and senns cx-300ii; and the Hd-600s and Fidelio x1 for full sized cans. Even next to the hd-600 which is hardly 'bassy' is not lacking in this department, while the re-400s are just deflated there. Such a shame.
The midrange is lush and smooth, and the treble is just right. The soundstage is very narrow, however, and the presentation lacks clarity and transparency. Also, the build quality is truly terrible: the wire from the Y split to the driver casing is very thin and the actual connection to the case is weak (it separated barely 6 months into usage). The tip assortment is fine, with the Comply Foam tips giving it a bit of extra bass hump it sorely needs. However, they make the presentation even narrower and more congested than it already is. Sillicon tips uniformly give the same bassless response.
These are horrendously overrated.
