Teufel Mynd

The Teufel Mynd impressed during testing and this is not so much due to the powerful sound or the very good runtime. Rather, the manufacturer thinks sustainable design through to the end and not only makes the speaker repairable, but also discloses the circuit diagrams and firmware code. Other companies should take this as an example, and not just speaker manufacturers.

Anyone who reduces the Teufel Mynd to its sustainable design and open source concept is not doing the Bluetooth speaker justice. Because even if you have no intention of tinkering with the Mynd in any way - apart from perhaps changing the battery in a few years' time - you're getting a really good product here...

The Teufel Mynd is a bold step towards sustainability and delivered a surprisingly powerful and full sound when tested. With its independent character, clever details and strong technical basis, it stands out favourably from the competition. Anyone looking for a robust, modular and powerful-sounding companion with character will find it here...

The MYND is great. In addition to the good sound, this is also due to the great features: power bank function, wireless music and via jack and USB-C connection. The speaker also scores highly in terms of sustainability: it can be opened and disassembled, components can be replaced and some can be retrofitted from the 3D printer.
