Turning the dial slides its round hole along the teardrop opening in the body. The less of the teardrop it uncovers, the more pressure builds behind it and the less air gets out.
A tool so good even witches call it magic. Resono Go brings our much-loved, patented dynamic resistance into a wearable form, so your Resono is always with you, ready to go.

Backstage, on a train, in rehearsals. Super light, on a corded necklace, ready whenever you are.
The dial is locked on, so it can’t drop off, even upside down. To clean, turn it to the lock mark, pull, twist and pull. It goes back on the same way.
Singing through a straw partly closes the mouth's exit, so a little air pressure builds up behind it. That back-pressure reaches down to your vocal folds and lets them keep vibrating with less effort.
Singers use straws for the same reason athletes train in a pool: full movement, less load.

Most straws have a fixed resistance, set by their width and length. Resono is adjustable, so you can load your voice precisely, like changing the weights at the gym. Our own measurements and modelling.

Everything you need to know about Resono Go.
Our team answers every message.
Contact UsResono Pro is our flagship modular kit, made from stainless steel, with attachments you can swap for your needs. Resono Go is a lightweight wearable with a built-in variable aperture, giving you a huge resistance range from a small device.
Yes. Resono Go assumes no knowledge of SOVT or straw phonation. With its built-in resistance dial you can explore exercises in a whole new way: just sing, spin, and find vocal balance.
No. Resono Go is your daily driver for SOVT work; Resono Pro is your full vocal multi-gym, with variable apertures, respiratory training attachments and resonance-extending features. They complement each other.
Soak it in hot water with regular washing-up liquid for a few minutes, clean inside and out, rinse and leave to dry. Avoid abrasive materials, which can scratch it.
This lowers back-pressure. Seal your lips firmly around the straw, and pinch your nose to check the flow.
One setting doesn't fit every range or dynamic. Match the resistance to the goal, and change it as your voice needs.
Warm-ups picked for your range, lessons you sing along to, and your pitch drawn live as you sing. Free on iPhone, Android and the web.
