Koostik Wooden Amplifier Dock For The iPhone (video)
If the Bone Horn didn’t quite meet your fancy, then perhaps the Koostik will.
It uses specially designed sound channels and hemispherical sound chambers that supposedly boosts your iPhone’s speakers two to four times. Why the variation in amplitude we don’t know, but perhaps it has something to do with the moisture in the air, or some other science variable we just can’t explain.
It comes in a variety of woods and costs $85.
