I don't think they do.
Side note I got the other products they offer today (R-10, R-11, R-30, R-Shield) and from what I've heard so far the R-30 is nice and the R-Shield sound way better than I thought they would, very balanced and not bass heavy at all. The R-10 and R-11 are pretty much what you'd think $20 IEM's would sound like, they're not bad but not that good either, I'll have more in depth reviews of all next week.
I saw the bolded comment by Techno Kid which prompted my initial post, well that and my Google search where I found Swimsonny's unboxing video.
Anyway since it was a Rockit product and one owned by the OP of this post and this is the most prominent Rockit product thread. I thought I could have some fun and try to cajole out some info about Rockit's only headphone.
