Within a couple of weeks they became loose fitting. I liked them so much, that I ended up buying my wife a pair when her cheap ear-buds bit the dust. I didn?t want to put anymore holes in my wall with shelves or poles, so this did the trick. Long time Sennheiser fan - normally purchasing mid range priced earphones, however the CX 3. Vale a pena. I did have a bit of a problem separating the two pieces as it says squeeze the tabs. It rubbed my heels raw. All you need is a single USB cable to charge your phone, watch and ear pods. I was upset because the lotion was broken in shipping. IMHO these are the most perfect summer footwear ever!
