Sure, go ahead and call yourself an audiophile because you have $300 headphones plugged into your iPhone; no one will believe it. That is, until you score V-MODA’s VAMP ($600), a pint-sized 150mW x 2 amplifier that turns your listening experience into a beautiful thing. VAMP is also powered by a 2200mAh battery, so it functions as a backup power source, nearly doubling the iPhone’s battery life. So even if your friends think an audiophile involves something dirty with little children, at least they’ll be able to recognize the extra juice your phone brings to the table.
