I was worried initially that they would become loose, but thats not the case either. I also wanted to get a set of earbuds that i could use when i play drums. This unit does not come with a charger, on top of that, I don?t own a compatible one, 9V/2AThankfully the unit had a huge warning sticker, before I slapped any charger to it :)! I ordered these as a replacement for my worn flip fops for in the house use. This is easily solved by taping the ends, but it is an extra step. Study & stylish. Will re-purchase. Doesnt provide anough power via USB. I purchased these to use as a bowline for my 12 Rib Boat as I wanted something that could be easily attached and removed, as I store my boat on a trailer. I was also hesitant because of the price.
