The Tribit Stormbox Pro doesn't sound as good as the competition, and the maximum volume is quite low - but the little handle man scores in all other areas: The controls are simple, the bass boost button pumps up the sound a bit without complications. It can also be used to charge external devices, which is no problem with the large battery: on one charge, the speaker played music for over 28 hours...

The StormBox Pro sounds good, offers a practical stereo mode for music playback in combination with a second box and is waterproof. It runs for a long time and can be used as a power bank. If you can live with the long charging time, the poor hands-free function and the lack of a jack socket, the box is worth a recommendation.

Slight midrange emphasis, otherwise balanced, the measured high-frequency drop results from the driver arrangement and is largely equalised in practice. For the format, it is surprisingly loud: 87 dB SPL (from 250 Hz).

Tribit's flagship mobile wireless speaker combines good sound performance with endurance and outdoor capability.
