Source: Digitec GalaxusThe Teufel Boomster Go offered the best sound among the affordable speakers, but at a maximum of 81 decibels it was rather quiet. This also weighed on the overall score, as did the meagre features with no additional connections and no app for sound settings. After a short period of familiarisation, it is easy to use and the battery life of just under nine hours is okay...
The Teufel Boomster Go offered the best sound in the tested. It plays back music in a balanced way, rich in detail and with strong bass, but the battery life is a little short at just under nine hours. There are no connections for other audio sources, and Teufel only offers extras such as a USB sound card and powerbank function in larger models such as the Rockster Go (130 euros).

The Teufel Boomster Go is a high-quality Bluetooth speaker in its size class. You can feel the good workmanship as soon as you pick up the Teufel Boomster Go, and its functions also show that it can do everything a Bluetooth speaker should be able to do. The sound is also convincing overall...
Teufel's smallest speaker prefers to play outside. The Boomster Go has a waterproof housing and a handy size. The sound is a little scratchy, but the speaker with an edge length of only 10 centimetres packs a punch - it's the biggest among the smallest.
