iPhone 4S PhonoBoost

iPhone 4S PhonoBoost



The PhonoBoost is a sturdy portrait facing holder, that also acts as an amplifier for the speakers on your Apple iPhone 4S. Our tests showed a significant and noticeable increase in sound output.

Here's how it works:

The PhonoBoost directs the sound from your Apple iPhone 4S's speakers through a small hole towards the bottom of the stand, and then around the back and out through the gradually expanding Phonograph trumpet.

The result is a highly directed and concentrated sound that cuts through normal background noise in a room to deliver clear and powerful volume output.

The PhonoBoost eliminates the need for expensive speaker docks and enhances the music playing abilities of your Apple iPhone 4S.

PhonoBoost: Expand your sound and extend your volume.
