“Hi we are Pauline and Maxime, we are both acoustic researcher and have a deep passion for music. Our mission? To help all saxophonists to find the saxophone mouthpiece that fits with their sound”

Syos saxophone mouthpieces are designed and customized thanks to science in acoustics

The sound of your dreams thanks to science


The sound of your saxophone is determined by the mouthpiece acoustics. Crafting its internal geometry, we are able to predict your sound, and then to shape it as you wish.

The saxophonist at the heart of the design


The search of your sound aesthetics is our most important goal at Syos. As long as you desire it, we adjust the shape of your mouthpiece, working at 1/100th millimeter.

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 Syos mouthpiece, we use your answers from the questionnaire to calculate the most appropriate geometry. You receive the mouthpiece and you can test it at home, in rehearsal, in concert… You can give us feedback that allow us to improve the mouthpiece if needed; to make it even more perfect. You’ll receive then a second version of the mouthpiece that you can test, etc… Last but not least, you’ll be followed 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 15 days 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 Thomas to discover more than 1000 different mouthpieces and better understand the influence of geometry on the sound. In 2018, Syos mouthpieces will be available in several places in Europe : subscribe to our newsletter to be informed of all our news.
