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.

    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 recieve 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.
