I would advide against getting these. I have a par that I picked up really cheap, and i almost wish that I hadn't paid what I did. The main problem with the is that they have NO bass. They have so little bass that the music really sounds unnatural. They have a decent amount of detail and mids, but the lack off bass just really takes away from what is acctually there.
These things suck due to 2 things.
1. The stupid loop support prevents these from getting a seal in your ears. Even if you mod them, they won't fit!
2. Without a good seal, it prevents bass from coming out. No bass means this IEM is not for ANYONE.
like the others have said, they're not that great. the loops things really keep them from getting a good seal with without the seal, the bass is too light. i thought that they sounded better without the loops but they were uncomfortable because i didn't cut the loops off in one clean pass and that caused burrs, which would irritate my ears. even without the loops and the better seal, imo the sound was uninspiring.
