Grundig Environmentally friendly design: The JAM Earth is made of 100% recycled plastic.

The inexpensive Grundig Jam Earth offers an acceptable sound and scores particularly well on the freestyle. Thanks to a battery life of 32 hours, it is also fit for longer trips. The Jam Earth also proved to be a real team player: thanks to its powerbank function, the speaker is the only test candidate that can recharge a smartphone via its USB port.
