Jambanz 2.0 Wireless Water Resistant Rechargeable Bluetooth 4.0 Portable Silicone Slapband Speaker with Mic - Blue Sonic Boom

This little gizmo is great. It does exactly what I was looking for. Two minor warning to users, though. First, don't become one of those obnoxious "walking boom boxes" and annoy everyone with your music. Keep it low enough that you can hear it without invading other people's audio space. And also, while exercising, perspiration can make the arm band somewhat slippery, but the problem is easily solved by adding a couple of velcros pads glued to it to hold it together. Have fun! With that, I love my JamBanz!

Works great. Happy with my purchase.
