We have a penchant for natural material gadgets like wood and bamboo here at GetdatGadget. There is something about the mashing of traditional and natural material and technology that really intrigue us. The Original Koostik Passive Amplifier for iPhone is a perfect example of this marriage between traditional and modern technology. This unique wooden sound amplifier is made from solid wood and it requires no electricity or batteries but yet can amplify the volume from your iPhone speakers up to 5 times the loudness.
The Original Koostik Passive Amplifier for iPhone uses the natural amplification abilities of the carefully designed hemispherical shaped sound chambers that are carved into the wooden block to deliver sound amplification without the need of any form of external power. The sound is amplified by about 10-25 decibels or an increase of 2 to 5 times of the volume.
The amplifier fits all models of the iPhone including many encased ones. The iPhone slot is 2.5″ wide and 0.5″ deep.
If you are the handyman type and don’t mind a little DIY to give your Original Koostik Passive Amplifier a personalized touch, you can get the DIY Kit version of the Koostik Amplifier that requires you to glue on the face plate, cut to size and provide finishing to the outer surface. You will also save quite a bit by going the DIY route.
