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

JK Exclusive mouthpieces deliver big tonal volume, pure intonation, easy response and precisely calculated resistance in cup profile and backbore, giving the player reliable endurance.

The player's personal tonal preferences and wishes can only be met with the highest level of technical precision. That's why Klier uses computer-controlled CNC lathes to produce their JK mouthpieces. Only this manufacturing method, thanks to its extremely precise positioning, achieves the required serial accuracy with tolerances in the µm range (thousandths of a mm).

Unique in the Mouthpiece Sector

The consistent rim and cup diameters within each series, along with exact and finely graduated steps, allow the musician to reach any desired style without having to change their embouchure. You won't find a mouthpiece series with such precise and optimally executed workmanship anywhere else.

Question by Thiel on 29.09.2025

I am looking for a trumpet mouthpiece, what does the designation 7 B mean?

Answer by Musikhaus Kirstein:

At Klier, the number stands for the inner boiler diameter or the edge width. The letter stands for the boiler depth. At Klier, 7 means a narrow boiler diameter and wide rim. B is the second deepest cup.
