SoundBridge is a minimalist passive amplifier designed for the shower: no electronics, no adhesives, just clever geometry. It works by redirecting and concentrating the sound from your phone’s bottom speaker through a waveguide tunnel, projecting it into the shower space.

To use it, simply place your phone face-up, with the bottom speaker aligned and covered by the cap-shaped section of SoundBridge. This cap seals around the speaker and forces the sound through the internal tunnel, which hooks over a glass shower wall and redirects the audio into your direction while you shower.

It’s the ultimate shower hack for anyone tired of muffled music and podcasts.
