These types of earphones are really used for running and such, which is why I feel I made a terrible decision buying these. Well, here's what I have to say.
It seems that these lack distinctly in mids. The sound is just a touch muffled, and it only make it worse that the design of the earbuds makes it difficult to position well. Besides the lack of mids, sound is alright. Nothing to write home about. For staying snug for a long time, I give it that. But for long periods of time, it really starts to hurt.
