The battery life isnt horrible but it isnt amazing either. I thought SCORE! Plug this device in and had a blast learning how to use it. I use it in the shower too. It?s PERFECT for organizing and cutting back on wires used for charging. Id forget I have it on if it didnt heat up. Let the jealousy begin again! Too small! I tried a friends beats and Jabra ear phones before I purchased these and the sound quality is of same standard but a much better price. So last summer I decided to pull the trigger and try a pair of crocs.
