Call us crazy, but the last thing you’d want to do is play music in the tub or shower—not with water, soap, and all those slippery surfaces around. But we do realize that bath speakers hold a certain appeal for some people. iDevices, creator of the iGrill Bluetooth cooking thermometer, this week at the Consumer Electronics Show in Las Vegas introduced the iShower, a water-resistant, Bluetooth-enabled speaker that plays music directly from Apple and Android devices. The unit mounts in your shower or can be taken to the beach or pool for up to 15 hours of listening. Priced at $99.99, it uses three AA batteries, remembers five Bluetooth pairings, and has a 200-foot range. www.ishowerinc.com.
