Josef Klier - Highest Quality From a Master's Hand!

JK Exclusive mouthpieces stand out with large tonal volume, pure intonation, easy response, and precisely calculated resistance in cup contour and backbore, giving the player excellent endurance.

A player's personal tonal preferences can only be met with the highest level of technical precision. That's why Klier uses computer-controlled CNC lathes to manufacture their JK mouthpieces. Only this production method, with its superior positioning accuracy, delivers the necessary serial precision with tolerances in the µm range (thousandths of a millimeter).

Unique in the Mouthpiece Sector

The consistent rim and cup diameters across the series, together with the exact and nuanced gradations, allow the player to achieve any desired style without having to change their embouchure. No other mouthpiece range offers such precise and optimally refined workmanship.
