The Ball Plug is the perfect solution as stationary and mobile speaker supporting both, Bluetooth and WiFi. You can use the speaker at any place you want.
When using the speaker at home, simply plug it into the socket. For outdoor use, the integrated battery with an autonomy of 8 - 10 hours will operate the speaker.
Furthermore, the speaker has a power bank function allowing you to charge your smartphone via the USB port.
The Wifi connection can be established either through the integrated WLAN card or through your external WLAN Router. Each speaker can be configured separately via the APPS provided with the speaker.
The speaker can also be operated via its Bluetooth interface.
A silicon sleeve can be used as a holder or to hang up the speaker.
