Owing to the french lockdown, we can't currently craft and send our mouthpieces and accessories. We will take care of the orders as soon as we get back, hopefully at the beginning of April, on the "first-come, first-served" basis. Take care.

    Clarinet mouthpiece


    The mouthpiece comes with a transparent cushion and a mouthpiece cap.

    Our brand name Syos is built from “Shape Your Own Sound” initial letters. Years of acoustics research led us to develop the technology and science to create mouthpieces fitting all musicians needs and wills. Our goal is to help saxophonists, and now clarinetists, get the sound they always dreamed about in the easiest way possible, and to be true to our promise behind the name Syos!

    After mastering our craft with the saxophone mouthpieces, we needed a little bit more than two years to finally get to the same level of demand on the clarinet ones. But that’s it! We can precisely model clarinet mouthpieces internal geometry! We are now able to alter the baffle, the chamber section, the tip opening, and the facing in a way allowing us to anticipate the timbre and sound you will get.
