AUDIOTWISTER - High-End Audio. Without compromise.

AUDIOTWISTER is a high-end amplifier in a very small space, which can play music directly via USB from a PC, Mac or any other Linux-, Windows- or Android-based system. When designing this module, the highest possible audio quality and maximum efficiency in the smallest possible space was the top priority. This completely new module, based on the latest components, offers an audio experience that was previously reserved for large, heavy and very expensive living room amplifiers in a size of only 100x65mm. AUDIOTWISTER is therefore extremely flexible and transforms existing hardware into a state-of-the-art HiFi audio solution in no time at all.

Due to its compact design with a very high degree of efficiency, AUDIOTWISTER is not only perfectly suited for mobile use, e.g. in vehicles, but can also be integrated directly into almost any object.

We at COMWORKS love good music reproduction and promise you AUDIOTWISTER was developed with great effort and passion and delivers uncompromising audio enjoyment par excellence.


best audio quality

Sound that arouses emotions.

integrated HiFi amplifier

Perfect sound. No noise.

2-zone audio

For all those for whom one audio zone is not enough.

compact design

Ideal for integration into existing products.

Maximum power.
Minimum size.

AUDIOTWISTER has been designed so that everything fits on a single small circuit board. You can wire your speakers directly via the terminal block. The power connector is designed so that you can use either an external power supply, a battery or a standard ATX power supply.

All you need is a PC, Mac or Android device with USB connection.
Of course AUDIOTWISTER also works as a module within a CIS infotainment unit.
Forget previous, complicated sound boards, power amplifiers, noise filters and connection cables of any kind as well as driver installations and software configurations.

Break the rules!

How is it possible to provide such performance on this compact size?

Of course, many people are rightly wondering how it is possible for us to place technology on a size -smaller than an audio CD- where other manufacturers offer shoebox-sized devices. First of all, it's worth mentioning that we never originally wanted to develop our own audio system, but we found that the market did not offer a satisfactory solution. Either the sound quality was not high enough or the output power did not meet our expectations, the devices were much too big, not mobile enough and too expensive. Other problems were noise, especially in mobile environments, e.g. when used in vehicles. A complicated set-up scenario often makes things even more difficult. Probably, however - and this will probably be the case - we simply come too much from practical experience to know what is really important and what ultimately motivated us to develop our own solution.

When we started developing AUDIOTWISTER, it was clear that we would only use the best technology and would not make any sound compromises. At first we questioned everything that makes up such a solution - sound quality, output power, robustness and size. The key for us was to design each of these components in the best and most advanced way possible. The result is something that is superior to previous solutions.

In the past, COMWORKS has often radically challenged classic product approaches and has taken completely new paths.
With AUDIOTWISTER it is time again. High-end audio in minimal dimensions, without compromise.
