Timbre Amplifier

In cases where "just a little bit louder" is loud enough, a passive amplifier like the Timbre can come in handy at augmenting and filling out the sound coming out of tinny-tiny iPhone speakers. The small wooden amplifier is rated to boost sounds by up to 20 decibels without the need for any power or batteries, all the while adding a beautiful desktop presence thanks to the black walnut wood finish (available in white or black front face).
