The $25 Amplifiear is an ingenious little device: It's a small, cup-shaped doodad that fits over the corner of your iPad to redirect sound from the rear-facing speakers around the front towards you, passively amplifying the audio along the way. It actually looks like your iPad is holding a hand to its ear saying, “Eh? EH? I can’t hear you! Speak up!”
The Amplifiear started as a Kickstarter project, but the vendor has announced that the project was successful and says that retail production will begin soon.
