So-so, but to be honest it's bulky and does NOT offer great isolation from background noise, the main reason for buying it as the sound really isn't that good. This is NOT an IEM, an in-ear headphone that's real as soon as you put it in your ear canal, hence the NAME! No, they're just cheap, pretty big for a professional musician's POSITION or whatever, except the sound is mediocre at best. I have $8 which is above isolation aspect and at least equal in sound quality. I have REAL IEMs, actually ORIGINAL. The Etymotic ER-4 that started it all, of course they cost 20x more but then they ISOLATE and were once considered the BEST EARPHONES IN THE WORLD and are still considered the benchmark for ALL IEMs! So my "reference" is high, and they're way too bulky for what you get, and many cheap or cheaper "earphones" are just as good or even better. BUT the sound isn't that much of an issue, it's just that they aren't that special and don't last long for some. I strongly recommend looking elsewhere. Sound quality is what you need, good luck!
