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 suits me?

When you order a Syos mouthpiece, we calculate from your answers to the questionnaire the more 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 expert 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 a 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.
