RE400 is in a little different category having a more neutral, reference, warm sound, laid back, smooth. IM50 and VSD3S are probably a better match for comparison. Both have a great build quality, though IM50 is built like a tank. It terms of over the ear fitment, VSD3S wins hands down due to it's westone-shure like ergonomics, while IM50 nozzle is a little too long which makes the shell stick out. With removable cables, you have 2-pin connection in IM50 vs proprietary mmcx in VSD3S; here IM50 wins due to a more sturdy connection though over-ear memory wire is PITA since you have to adjust it every time these out of the case.
VSD3S has a wider/deeper soundstage with a better separation/layering of a sound. IM50 is narrower and more aggressive/upfront while VSD3S sound pushed a little bit back, more relaxed. When it comes to low end, both have a decent extension but IM50 goes a bit deeper in sub-bass and has faster and more aggressive mid-bass punch with more quantity. VSD3S bass is more detailed, but mid-bass is more rounded and not as aggressive. Both have a great bass control without spilling into lower mids or overpowering the rest of FR. Mids are where you hear the biggest difference since VSD3S is brighter, a little harsher, and sounds a bit thinner in comparison to IM50 which delivers a typical Audio-Technica quality mids that are smooth, organic/natural, and have a better delivery of vocals. VSD3S delivers more details when it comes to mids, but I find IM50 easier on my ears. Treble in both has a great extension and details, but due to it's brightness VSD3S is on a borderline of sibilance while IM50 is smother.
There is no clear winner, and all up to a personal preference. Both IM50 and VSD3S have an amazing value, considering a price tag of $60-$70 with removable cables and an excellent detailed sound. Those who "allergic" to too much bass might find IM50 too aggressive while people who are more sensitive to high frequencies might not like VSD3S. I also hope, cable replacement will add to sound quality. I'm currently waiting for silver-plated replacement cables from lunashops for IM50/IM03 which I hope can brighten the sound. While, perhaps new replacement cable from VSD3S will improve a connection without adding more brightness and adds some memory wire for a more secure over-the-ear fitment.
