The NX Acoustics musicplayer was designed to enlarge the ONE series product range with a likewise concept fulfilling less-is-more design. The design concept for the earplugs was driven by the idea of encoupling the housing from the cables influences which lead to a simplified concentrical design. Thus for the musicplayer the same idea of a concentrical layout was mandatory.
The cable connection is the central part of the musicplayer and thereby coaxially integrated. (For the use under wet conditions there is a specific earplug set available which magentically proofs the transition zone between the components.)
Equally the operation is conditioned by the concentrical layout: thus the operational components exist of two control rings. By a integrated shift-button the functions can be switched between track and volume. The hold-function can be accessed by pressing the presets additional button.
