If your singing in the shower requires accompaniment, you can use the iShower wireless speaker to bring music from your Bluetooth-equipped phone or music player along.
Even though it's called the iShower, and is a largely white rectangle with rounded edges like a certain company's popular devices, the water-resistant speaker will work with Android phones and tablets, as well as with Apple products, including the iPod Touch.
The roughly 9-by-4 by-1-inch box has start, pause, forward and back buttons, as well as volume up and down. These controls will run your device remotely, so you can skip past the techno tracks and get right to the karaoke cuts while keeping your music source dry.
The $100 iShower has a swing-out stand that doesn't lock in position, so it tended to collapse in the slippery tub. It also has a wall hanger, but that puts the two-inch rear speaker right against the tiles, which isn't good for sound fidelity.
On the stand the sound isn't bad, certainly adequate for the echoey shower enclosure, but even in that small space, the amplifier - driven by three AA batteries - won't get particularly loud.
While the speaker is water-resistant, you'll want to keep water from spraying directly into it. There was some distortion when I gave it a direct soaking (though it was fine again after drying).
The Bluetooth hookup was fairly simple, and the iShower can pair with up to five devices, in case you share the shower with a quartet.
It also has a clock that can be set to glow behind the faceplate, so you don't lose track of time while doing your best Bobby Darin.
