Summary: I purchased this product for my autistic son to use with his iPod touch. He uses the Proloquo2go application for communication. While the product is great for protecting the iPod when dropped, it does not have good sound output for use in loud environments. The main reason I purchased it was because I thought it would make the iPod louder and easier to hear in loud environments.
Summary: Pros: Good sound for size, there is room to store some additional accessories, compact enough to take with you anywhere, keeps your device protected. Cons: Somewhat bulky relative to size of Mp3 player or phone, no external power adapter for speakers or device, could have been rechargeable cannot access Mp3 player or Phone power button without opening the darn thing, No volume control, and batteries can be awkward to put in.
