Three are 3 straps on the closed end to hold it securely to the carrier same number in front, also not very user friendly. I forget they are in my ear. These turned to be the best headphones Ive ever listened to. As of now, yes I would recommend these to friends and yes I would buy them again. I folded them up and put them in an old Huggies wipes bin and soaked them in cleaner. They are well made and I believe they will last a while. What I don?t like:- It gets dirty SO FAST! I am able to wear it all day and walk around without feeling any discomfort on my heel. When plugged in theres a noticeable bump in volume, but also theres a bump in sound quality as well. Im not going to bother getting a bumper case to protect the sides of the watch although I see no reason why any case wouldnt fit onto the watch in addition to this shield.
