Behind MYSPHERE 3
The roots of MYSPHERE 3 go back to the legendary flagship headphone K 1000 of AKG, introduced to the market in 1989. Two outstanding acoustic engineers are associated with the history of the K 1000: Helmut Ryback, who developed the AKG K 240 DF, at that time reference headphone for many radio stations, and Heinz Renner, leading in concept and development of the K 1000, together with Helmut Ryback.
MYSPHERE 3 has been developed by LB-acoustics Messgeräte GmbH applying their core competences in sound and vibration measurement technology. Meeting the requirements of the audiophile community all measurements are carried out according to the latest technical standards. This includes simple sound measurement as well as mechanical vibrations and psychoacoustic tests. But the final examination is made by the human ears of our test persons, which significantly influences the whole design concept.
Philosophy
New materials, improved computer simulations, revolutionary measurement methods like psychoacoustics, artificial head (head and torso simulation), laser vibrometers and others opened new possibilities for the construction of acoustic devices. So the master minds behind the K 1000, Ryback and Renner, decided to apply their experiences to the development of the ultimate headphone – the MYSPHERE 3.
Transient Response
An ultra light coil and a glass foam membrane with a cobweb structure allow fastest impulse reproduction. All dispensable air volumes like tight channels, slots, holes etc. are largely avoided in order to reduce additional acoustic masses.
Spatial Sound
Supported by the open design, the drivers are kind of levitating over the ear. The open front cushion enables sound to flow from one side to the other and vice versa. This creates an unprecedented binaural effect and great spatiality.
Open design
On both sides of the moving membrane the spaces are completely vented. No acoustic volumes hamper the membrane in its movement and the front cushion is acoustically open. This yields an unsuspected sense of space.
Innovative frame construction
A light metal frame transmits the force from the soft cushions to the head to achieve very small specific surface pressure. Sensitive areas of the head are bypassed resulting in a well-fixed headband carrying the hovering drivers.
All cushions are attached by magnets and can be removed manually without tools.
Additionally, both sides of the earphone can be removed without tools to facilitate the transportability and service.
Since no human head is really symmetric, all adjustments of angle and height have been accomplished without mechanical lock-in positions. A fine scaling allows for easy retrieval of personal settings.
