Singing in the shower just got a hell of a lot more fun. Kohler’s Moxie Showerhead and Wireless Speaker plays music wirelessly from your smartphone or iPad, so you can have some backup music while you croon and shampoo. The magnetic speaker pops in and out of the showerhead for recharging, and can be used anywhere. It’s set to go on sale this week. $199 at amazon.com.
