I bought this just today, and they are pretty good so far, no issues yet. its comfortable in the ear and adjustable if it isn't, the sound is average, not a wow factor but its adequate. The design is pretty cool and the size is not too big. Connection was smooth, as soon as I opened the box they were already charged fully, all I had to do was pair it with my phone, no problems at all. The only things I think they need to improve on, is the sound quality and the buttons on the earbud, instead of a button, a simple touch control would be more ideal, since I have to really press down on the earbud button to play/pause/skip sometimes with 2 fingers.
