The iPhone Horn Stand Amplifier gives modern technology a major retro boost. Entirely made of silicone, the horn stand fits around the base of your iPhone, allowing it to stand up horizontally or vertically. It doubles the output volume the old school way through an acoustic amplifier with 12 dB. Like a trumpet, the sound is concentrated through the horn, amplifying it without electronics or batteries. Slip it around the bottom edge of your iPhone and add 12 decibels of acoustic output power to your iPhone, without eating up your battery!
