Bluetooth Showerhead Music/Phone speaker. With MusicJet™, you can rock out to your favorite music in the shower—which we all know has the best acoustics in the house. Just activate Bluetooth™ and your mobile phone’s music player, and MusicJet™ will do the rest! But that’s not all. Incoming phone calls will be automatically forwarded to you in the shower. With the simple press of a button on the showerhead, MusicJet™ becomes a phone – complete with automatic noise reduction technology. End the call, and your music resumes automatically! The MusicJet™ takes a single lithium ion battery, which comes included, along with a USB charger. One charge is good for ten solid hours of music or phone conversation.
