>>21230413for real IEMs you should get custom molds and they will be expensive. i don't really look for quality if what you mean by IEM is just "earbuds." the industry standard is mas o menos JH Audio, again....lower price points are fine if all you're ever doing is listening to music. if you're just looking for small form factor earbuds shit i'd shop around JBL, some of it is pure trash and some of it is really great. they're the only manufacturer that makes products from pro pro pro level to shitty consumer, the R&D does trickle down but my experience has been hit or miss. again, audiophiles are ghey...if your ears work you'll know what is good and what isn't.
