Pros: Midsection, It's basically FREE,
Cons: Lack of Bass,
I'm not sure if this is the same model I got with my iPhone 4s or not. There have been tons of different models of these buds released for different i-devices. The ones that I received with my 4s are (In my opinion ) absolutely worth at least 30-45 $ in my opinion.
No they don't sound like my SENN HD 600 by any means at all, but for an earbud they are exceptional. The mid - section sounds nice to me and the detail (although not much) is far better than any dollar-store ear buds I have ever tried on (And trust me I have tried all sorts).
What is holding it back from being 5 stars is it's bass (these really have nearly no bass) and the slightly-generic sounds in the highs. And no I'm not trolling when I say these are some of the best ear-buds ever made. (Ear-buds )
