What are the best features of Syos mouthpieces?

Syos was created by Pauline and Maxime, two French researchers in acoustics. Thanks to science and new technologies we design mouthpieces that are:

  • Easier to play
  • More accurate and more homogeneous
  • Able to produce the exact sound you are looking for

Syos mouthpieces are strong, durable, certified non-toxic, and available in a wide range of colors and openings.

What material are Syos mouthpieces made of?

Our mouthpieces are made from SCAL3D, a new proprietary material we developed in-house. SCAL3D is durable and optimized for 3D printing, without compromising the excellent acoustic properties of Syos mouthpieces.

How do I know which mouthpiece will work for me?

Syos designs mouthpieces for every type of sound imaginable. Whatever your expectations, there's a Syos mouthpiece that's right for you. Our online store provides detailed information on each mouthpiece and the type of sound (bright or dark, soft or powerful...) they are best suited for. If you need further guidance, you may contact us via chat, phone or email (all info here). Our customer service team is here to help you find the perfect mouthpiece.

What if I dislike the mouthpiece?

Upon receiving your new mouthpiece, you can try it at home for up to 30 days and send it back if something feels wrong. Should you do so, we will offer you an exchange (another model or another opening) or a refund of the product. Please note that shipping fees are not refunded.

Where can I test Syos mouthpieces ?

You can try Syos mouthpieces in our Paris studio, 3 cité de l'Ameublement 75011: book an appointment with Sylvie, Madeline or Brian to experiment with more than 100 different mouthpieces and understand first hand how differences in geometry influence tonal quality. We also have distributors all over the world, find the nearest one with our dedicated map (We recommend you call the store beforehand to check what models are in stock). Last but not least, you can order one or more mouthpieces on our website to try them out, and send them back (within 30 days) if they feel off.

Once I order, how long does it take for the mouthpiece to arrive?

All Syos mouthpieces are made to order. There are two steps to each order:

  1. Manufacturing the mouthpiece. This step can take from 3 to 5 days. We will send you an email as soon as the mouthpiece is ready.

  2. Shipping the mouthpiece. We ship in France with La Poste, and in the rest of the world with Fedex (except Russia, Central and South America). Delivery time is 2 to 4 days for Europe and the United States and may be longer depending on the country. You will receive an email with the tracking number once the package is sent.

Here is a breakdown of average delivery times recorded over the last few months in the countries we ship most of our products to.

Please note that for an exchange or improvement to a custom model, the mouthpieces are shipped via standard mail, resulting in longer delivery times. If you wish to have the mouthpiece sent by express mail again, simply tell us and we will pass the extra shipping costs on to you.

My hard rubber mouthpiece broke, can Syos make a replica of it?

We do not make copies of existing mouthpieces, but we can design a Syos mouthpiece with a geometry that produces the same sounds, is easier to play and more comfortable.

Are your mouthpieces safe to put in the mouth?

Our mouthpieces are made of a material that has been lab-tested and certified non-toxic, therefore they are completely safe to put in the mouth, as opposed to the "ebonite" conventionally used to make mouthpieces, which contains sulfur. Over time, sulfuric acid is released, giving the mouthpieces a yellowish tint as they age. No such worries with Syos mouthpieces in SCAL3D!

Which reeds work best with Syos mouthpieces?

Syos mouthpieces are compatible with all reeds. We recommend that you try first your current reeds, and should the opportunity present itself, other reed models. If you picked a bigger opening for your Syos mouthpiece than what you are used to, it may be worthwile to try reeds with a slightly lower strength (and vice versa).

How can I track my order?

You can track your order in your customer area, under "My pending orders" tab. Once the mouthpiece is shipped an email is sent with a link and tracking number. When in doubt, feel free to contact the Syos customer service team.

How do I request an exchange or refund?

If you wish to return a mouthpiece, make sure you received it less than 30 days ago. If so, fill in the form in your customer area under "My current orders" tab. This form details the procedure to send back your mouthpiece (print voucher, return address...). Be advised that any return outside of this form will be denied. Return costs will be your responsibility.
