If you like listening to music in the shower, check out the MusicJet. It’s a shower head mounted speaker. This speaker connects to your iPhone by way of Bluetooth and has a range of up to 10 meters, letting you keep your phone outside of the shower while still playing tunes. The ShowerJet has a rechargeable battery that lasts for up to 10 hours of audio playback.
No word on the voltage of the shocks though.
The speaker also has a built-in button for accepting calls in the shower, which aside from being extremely awkward, seems like a very bad idea.
