The ERGO A.M.T. employs a completely new drive unit, the Air Motion Transformer.
The Membrane works with a transformation of 5:1, i.e. the air movement is 5 x greater than the movement of the membrane. The unfolded membrane is 175 x 88 mm large.
These speakers are manufactured by Precide to meet the highest quality standards, based on the Theory of Dr. Oskar Heil.
The most remarkable feature of the AMT Speaker units is the extremely fast reaction to impulses, this ensures correct phase relationships and excellent dynamics.
You can detect details in the music, which simply cannot be reproduced by other speakers.
Even after long hours of listening to this system, stress symptoms will not occur. This is specially due to the correct phase and in particular the total absence of the partial frequency distortion, always present in any suspended three dimensional object, when moved.
The ERGO A.M.T. headphone can be used with either its designated amplifier (ERGO AMP1or 2) or with an adapter ( 4 leads to the 4 pin XLR socket , which allows the use of your amplifier

Here a short description of the ergonomic for the headphones
A) The ERGO headphone rests lightly on top of the head, the weight, mere ounces, distributed over a large insensitive surface. This light weight and soft foam headband cushion result in complete freedom from pressure and allows the scalp to “breathe” naturally.
B) A foam strip, at the rear of each speaker panel, rest lightly behind each ear. These do not contact the ears to cause any deformation, which would obstruct the natural sound field created by the speakers.
C) the speaker panels are fixed in the correct position to maintain optimum vertical and horizontal angles of sound dispersion.
D) Since the speaker panels do not physically contact the ears, the intervening spaces permit a fresh air-flow from below the ears, which avoids the heat, perspiration and listener fatigue so commonly experienced with conventional headphones.
Conventional headphones distort the shape of the outer ear and pump sound directly into the auditory canal depriving the ear of its natural function.
Such headphones may have a wide frequency response, but by contacting and deforming the ear they lose or distort the second (indirect) sound wave information, resulting in unnatural sound reproduction and listener fatigue. More information on our home page:
