V-MODA VAMP

What It Is:An amplifier for the iPhone 4 or 4S that adds punch to your music collection, improving the quality and power of the sound.

Why It's One to Watch: V-MODA VAMP uses better digital to analog conversion than the iPhone itself, so the music quality is crisper and more authentic. Plus, the device also works as back-up battery, which is handy for long plane rides.
