Jambanz - wear a Bluetooth speaker on your arm.

  Here's how the company puts it: Jambanz are the safe alternative to headphones. Jambanz wearable bluetooth speakers let your music move with you – whether jogging, biking, skateboarding or playing outside. Jambanz wirelessly plays audio from your iPod touch™, iPad™, iPhone™ or bluetooth Android device to your wrist, backpack, belt, handlebars, lamp… whatever you slap it to! --But wait, there's more --- Jambanz silicone slap bands let you switch the speaker with other bands to mix-n-match or collect and trade with friends. And Jambanz are USB rechargeable, so there’s never any batteries to buy. (A full charge will last 2 to 4 hours depending on the volume. Hopefully you won't play it loud enough to annoy others.) And you want Jambanz version 2.0. It features Bluetooth 4.0 with extended range, built-in microphone for taking calls, improved sound, and new colors and styles. So now you'll be able to answer phone calls over the speakerphone. I agree with the company that Jambanz is a safer alternative to headphones, which can block out surrounding dangers and potentially cause hearing damage. Just don't play it too loudly. Actually, for it size, the sound is very decent. MSRP is $32.99. The earlier model was $29.99, but you want version 2.0 for just about $3 more.
