who used to jog with wired, it was not very practical especially when using RunKeeper same time. Looking wireless earpiece, I was skeptical about the quality of these headphones saw their very affordable price. After receiving and 3 trial races over an hour, I'm amazed. the sound quality is quite good, the bass is present and the volume control only what is necessary. Well do not compare with my boose but frankly for running, that's enough and even better from what I expected. bluetooth grip is excellent, I have experimented with leave from the living room and into the next room and it easily passes close so do not talk. autonomy issue, I have already made more than 2 hours of racing and it does not even move, I assumed that it leaves its holding 5h advanced to perfect for a marathon.
In short I recommend, so good after 2 weeks of testing
