I love these wireless earbuds. They are very comfortable and the sound is better than I expected it to be, Everything fits in the little round charging case. They charge pretty fast and have been great at keeping a lasting charge. The insructions are very detailed and easy to understand. It comes with two extra pair of earbud caps. I have been using them for a couple of weeks and I don't have any cons to tell you about. They are much better quality then I expected and I am very happy.
