Although the device itself, the tone will be switched louder and softer, but not the track to be changed. Who would not connect via Bluetooth with the Boombag, connects his device using the supplied jack cable. About the MicroUSB jack and port is also a cover to protect the connectors from dust.
In recent weeks, I have determined the Boombag about six hours than Bluetooth but 7.5 hours per jack cable as standard battery life. Thus one creates every game night, small barbecue party or even work at home.
If you look closely at the front discovered a small entrance: the Boombag also serves as a hands-free system for smartphones. This has worked out great, my opponent was able to understand well during interviews.
