I owned a pair of these briefly, if you are looking for bang for your buck than they will deliver.
However, they are very lively and not accurate. A bit sharp and the low end is very pronounced. Mids are more recessed if I recall correctly. Had to get rid of them because they would give me listener's fatigue after more than an hour.
For the money they are asking for them though, they are definitely worth more...
Also, if you are on the website, pick up the 8320 IEMs. If you can get a good fit, these kill many under $75 IEMs for sound quality. Extremely well balanced IEMs...
