I received it last night, and I just use this noon for a quick jog 45 min. SONY headphones this is just perfect. It remains perfectly in place throughout the workout, it's so light that you end up not feeling it, the sound quality and bass response are more than respectable for the style of music I listen to (metal ), in addition, the headphone jack is bent. Just thirty seconds to put in place the 2 ears, the headphones fit perfectly in the ear to not get out. You just put the clips (provided) for holding the wire, otherwise every stride you feel the thread that pulls the two atria (it's just boring current). I have long been looking for a helmet that suits me to play sports, and there, I found one that suits me !!! For amazon, delivery on time, but the plastic blister product arrived completely exploded (I was afraid for headphones, but it is not damaged.
