Resono Go: Vocal Warm-Up Tool for Singers (SOVT Singing Straw Trainer)
Resono Go is a wearable vocal warm-up tool that brings the proven science of SOVT straw phonation into a lightweight, portable design that’s ready whenever you are. Built for convenience without compromising on effectiveness, it uses the same patented dynamic resistance technology found in Rayvox singing straws - just in a smaller, more affordable package designed for everyday voice training.
Simply wear it around your neck with the included cord and warm up your voice anywhere - backstage, on tour buses, between lessons, or even during your morning commute. Designed for singers and voice users, it helps reduce vocal strain, improve resonance, and support consistent vocal training wherever you go.
Resono anywhere you Go.
A tool so good even witches call it magic. The Resono Go brings our much loved, patented dynamic resistance technology, into a new wearable form, so you'll always have your Resono with you, ready to go.
Resono Go Features
Built In Adjustable Resistance
We have integrated our patented variable aperture technology into our smallest form factor yet, whilst improving the range of resistance offered. The Resono Go features a built in dial to control the amount of resistance.
Wearable & Always With You
Do you love doing your SOVT work backstage? On a train? In rehearsals? The Resono Go is super lightweight and comes with a corded necklace, so you'll always have it with you, ready to go, whenever you need some straw phonation magic.
Food Grade Materials
Made from high-quality, FDA certified food-safe materials. The Resono Go is easy to clean, durable, and safe for daily use.
Why Adjustable Matters
Compare the resistance range of different SOVT tools
The chart above visualises the range of resistance that different types of straw can provide. Most have a fixed resistance due to their fixed aperture and length, but the Resono is dynamic and can change resistance.
Having an adjustable resistance system allows for more precise control over vocal load, just like adjusting weights at the gym.

How It Works
Understanding the science behind SOVT and straw phonation
Small but MIGHTY
From one small device comes so much power. With our patented variable aperture, you get a huge back-pressure range, from 1.5 cmH₂O to 30+ cmH₂O.
This is the equivalent of carrying dozens of different straws in your pocket.
What does back-pressure do?
Back-pressure is the gentle cushion of air that builds up above the vocal folds when the vocal tract is partially closed by a straw.
That extra pressure helps to lower phonation-threshold pressure (the effort needed to start the folds vibrating) and reduces collision forces each time they meet.
The net effect is easier onset, more stable tone, and a lower risk of fatigue or injury.
Resistance, visualised.
We've run 1000s of simulations exploring the vocal benefits of our devices, and we've built a brand new mathematical model that allows us to accurately determine the back-pressure offered by any configuration of the Resono, singing straw, or regular straw.
The Benefits
Sing like never before
Rayvox tools are designed to help you train your voice, and reach new vocal heights, build muscle strength, coordination, and efficiency that lasts a lifetime.
You can truly build the voice you want: eliminate voice cracks, achieve better vocal fold closure, avoid strain and vocal tension, improve your breath control, and sustain notes for longer and more efficiently. All from one device.
You can even do it on the train!
Frequently Asked Questions
Everything you need to know about the Resono Go.
The Resono Pro is our flagship, fully featured modular kit. It's made from high quality Stainless Steel and includes various attachments that you can interchange for your needs.
The Resono Go is a new, lightweight device that features a built in variable aperture, giving you access to a huge resistance range from a small, wearable package.
Yes! The Resono Go has been designed with beginners in mind. It assumes no knowledge of SOVT or straw phonation - and with it's built in variable resistance dial, you can dynamically explore exercises in a whole new way. Just sing, spin, and find vocal balance.
The Resono Go is super easy to clean.
You can use your regular dish detergent and hot water. Let the Resono Go soak for a few minutes before cleaning the inside and outside thoroughly. Then rinse and leave to try. Avoid using abrasive materials as they can scratch the device.
No! The Resono Go is not a replacement. The Resono Go is a lightweight wearable designed to be your daily driver for all things SOVT. The Resono Pro is designed to be your full vocal multi-gym, offering variable apertures, respiratory training attachments, as well as resonance extending features.
We like to use them to compliment each other. The Resono Go can be worn all the time so it's there when you need it. The Resono Pro is for when you need to take your voice to the gym.
Yes! The original Resono and original SOVT Straw devices have now been discontinued (except the Pro Kit). The Resono Go is now our default entry-level product.
Problem: Lowers back-pressure and defeats the purpose.
Fix: Seal lips firmly around the straw and pinch the nose closed to check flow.
Problem: Adds constriction and raises effort.
Fix: Keep jaw neutral and cheeks relaxed.
Problem: One size doesn't fit all ranges/dynamics.
Fix: Match resistance to the goal and don't be afraid to increase or decrease as your voice demands.
Problem: Might cause excess tension or build too much pressure.
Fix: Relax/back off the flow. You can try using some water or the Spinner to visualise the output.
