The ERGO model 1 and 2 utilize rugged and reliable dynamic-type reproducers. Both models can be connected directly to the standard 6.3 mm (or optional 3.5mm) headphone sockets of a stereo amplifier, receiver, tape deck, CD player, TV and PC.
The ERGO 1 is equipped with two dynamic drivers with thin membrane diaphragms. Thanks to the correct acoustical placement of the drive units the sound is clear and uncoloured. The high quality sound and reasonable price of the ERGO 1 surprises everyone
The ERGO 2is also equipped with two dynamic speakers which employ neodymium magnets even thinner membranes to reduce distortion to a minimum. The result is sound reproduction which is open, transparant and uncoloured, it approaches that of an electrostatic system

The ERGO A.M.T. is a world first! For the first time, it has been possible to incorporate the proven principle of the Heil Air Motion Transformer into headphones. The extraordinary thing about the A.M.T. is its extremely fast impulse behavior, which benefits, among other things, the fine dynamics and phase behavior: voices appear clear and natural in all nuances. You can hear details that simply cannot be reproduced with other playback systems. Even after listening for a long time, there are no signs of stress, which is thanks in particular to the phase-correct emissions without partial oscillations. The ERGO AMT can be operated with its AMP 1 amplifier (also suitable for dynamic listeners), or with the AMP 2 Class A, which was only developed for the ERGO AMT.
