I had long known about custom IEMs (that stands for 'In Ear Monitor'), and that custom IEMs were supposed to be much more comfortable, and also deliver even better sound than standard earphones were capable of. The problem, of course, is cost. Typically, the cheapest IEMs cost about $700 for a pair. Enter inearcustom.com, which offers the perfect solution. The website inearcustom.com promised to make ANY pair of earphones into a custom IEM for just over a hundred bucks. That's a LOT cheaper than anything else on the market, and I couldn't resist giving it a try. Read the full review for my experience.
My original pair of InEarCentral IEM's, made with Shure SE530 monitors. These sound INCREDIBLE, but cost about $300 more than the SE210 version.
