The Syos mouthpiece is always easy to play and responsive, no matter your style preference.
The acoustic optimization of the input impedance gives you precise pitch accuracy.
Our experts will help you choose or design a mouthpiece suited to your sound.
The concept
Looking for a dark and powerful sound? Or rather a bright and focused tone? The internal geometry of a mouthpiece determines its acoustic properties. We design mouthpieces with the shape to suit your sound.
The special signature edition
Tivon Pennicott
My Syos mouthpiece is uniquely comfortable for me. I can easily access my altissimo while also blowing through my low subtone notes with ease.
Chad Lefkowitz-Brown
My Syos mouthpiece helps give my sound tons of power and a thick core. It’s always super easy to play and helps me articulate clearly, even on fast lines!
Yoann Boucher
Syos is a fine combination of savoir-faire, quality and attentiveness to the musician’s needs.
Frequently asked questions
Custom mouthpieces, how is that even possible?
Syos was founded by two researchers in acoustics. We studied both the physics of wind instruments and auditory perception (and especially the sound vocabulary), so we established relationships between sound characteristics and mouthpiece geometry elements (chamber, baffle, tip opening, etc…)
How can you be sure that the mouthpiece will suit me?
When you order a custom Syos mouthpiece, we use your answers from the questionnaire to design the most appropriate geometry for you. Once you have received the mouthpiece, you can test it for 30 days at home, in rehearsal, in concert… You can give us feedback that allows us to improve the mouthpiece if needed; to make it even more perfect. You’ll then receive a second version of the mouthpiece that you can test, etc… Last but not least, you’ll be helped by one of our acoustician experts during all the process!
I’d like to test it before buying it. Where can I do that?
When you order a mouthpiece, you have 30 days (from the day you receive the mouthpiece) to try it at home and you can send it back if it doesn’t suit you. You can also discover Syos mouthpieces in our studio in Paris: book an appointment with Sylvie to discover more than 1000 different mouthpieces and better understand the influence of the geometry on the sound. We also have retailers all around the world, find the closest one on that dedicated map.
