But all the cases we've seen have one thing in common: they obstruct the iPhone's speakers at the bottom of the phone, making it more difficult to hear what you're playing. And the iPhone's speakers aren't that great to begin with. That's where the AudioGlove comes in.
The AudioGlove is a two-piece case which slides open to amplify the sound from your iPhone speakers. Falco Freeman, who designed the case, says the result is a boost of 10 decibels, or about 20% more sound than normal.
