BACKGROUND

Portable electronic devices such as music players, mobile phones, and the like are commonly used or carried by people performing physical activities such as exercise. Such devices are typically not very rugged and do not often react well to the physical shocks associated with such activities. If the activity involves exposure to water such as with swimming, the hazards to the electronic device are multiplied as few devices are water resistant let alone waterproof to any degree. What is needed are design and functionality improvements to portable electronic devices which increase their durability and utility when used in conjunction with physical activities such as running, swimming, and the like.
