Dont worry about the size. Something needed to be done! They are a little large for my ears, but I would still recommend them. Doesnt take up a lot of room like other 3-way chargers. I sized up by a full shoe size (normally always a 9, bought a 10) and they still are too small. They are not collapsible, if anyone was wondering, I usually carry mine around in a small purse if I am not wearing them. Or are planning on also placing any long boots on it unless you place them on the top shelf only, but that means you can only owe 1-4 pairs. I got them to walk around the house on hardwood floors, I dont think I would wear them outside unless I resolved the slickness of the foot surface. However, I read some reviews that said the battery charges in mere minutes, but thats not true. These earbuds are literally the only ones I found that could be used for lap swimming and can store music as well.
