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

JK Exclusive mouthpieces deliver generous tone, pure intonation, easy response and precisely engineered resistance in the cup and backbore, giving the player excellent endurance.

A player's personal sound preferences and wishes 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 fine positioning accuracy, produces the necessary serial precision with tolerances in the micron range (thousandths of a millimeter).

Unique in the Mouthpiece Sector

The consistent rim and cup diameters within each series, together with the exact and differentiated gradation, allow the musician to achieve any desired style without having to change their embouchure. A mouthpiece series of such precise and optimally executed design cannot be found in any other offering.

This is the mouthpiece I have. With it I can play pieces where I already wanted to give up. The service is just great. I can only recommend the Kirsten company. The music house is my first choice from now on.
