At its current price Id look elsewhere and honestly Im sure youll be able to find something much better for less expensive price anyway. I am writing this review because these earphones stop working within about the month of purchase. But these! The only reason I have had to replace them is in traveling I misplaced them. I want more in different colors/designs so I hope they come out with new designs soon! It does not fit the electric citibikes as the battery is too thick to attach the swing arm for the seat. I know its adjustable but that doesnt change its grip. They will give slightly, but you dont want them tight ever. ps I think my dog would like some too! This is very poor quality.
