Physics meets voice science

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.

Small but MIGHTY

From one small device comes so much power. With our patent-pending design, you get a huge back-pressure range, from 1 cmH2O to 30 cmH2O and beyond.

The graph represents some of our favourite options. There's so many, we couldn't fit them all on.

Revolutionary Resono vs. standard straws

One size does not fit all. Everyone will need a slightly different amount of resistance, meaning a different sized straw. Other singing straws on the market only offer a fixed length and diameter, so they can only offer a single fixed resistance. Our tools offer multi-resistance from a single device, meaning you only need one, and anyone can use it.

Sing with ease. Recover tired vocal folds. Gain vocal power without straining. Increase vocal range. Reduce vocal fatigue. Achieve faster vocal warmups. Adjust breathing for relaxation. Reduces anxiety. Sing with ease. Recover tired vocal folds. Gain vocal power without straining. Increase vocal range. Reduce vocal fatigue. Achieve faster vocal warmups.

Science in the press

"Straw phonation not only lowered the onset of normal voice, but also elevated the onset of chaotic voice, indicating a better voice economy and voice control. Moreover, the improved phonatory range demonstrated that straw phonation had the potential to prevent voice users who have high voice demand from voice fatigue and vocal damage."

Kang et al., 2018

"We think Semi-occluded Vocal Tract exercises are brill. They have a solid of research behind them and have been helping singers clinically for years. Bringing these into your daily warm up routine, or even more than once per day, will help you to warm that uncooperative little monkey into a beautifully functional instrument in half the time." 

iSingMag, 2016.

"The straw phonation exercise caused positive effects, seen upon voice self-assessment, indicating an easier and better voice upon phonation."

Costa et al., 2011.

"Narrowing the vocal tract increases air pressure above the vocal folds, keeping them slightly separated during phonation and reducing the impact collision force"

Fulfills all my vocal practicing and warmup needs

The straw is easy and comfortable to use, and its high customisability makes it a perfect fit for any vocal day, whether you're in top shape or feeling really off.

I bought a Resono Pro for my wife who is a vocal coach and we absolutely LOVE it!!

Speedy response times and super friendly customer service for a greta product, couldn’t be happier!

Every singer should have this in their tool box

This is something I never leave the house with out. Between steaming and hydration I would say this is the other must in my tool kit. It’s a great tool for gently stretching the vocals. It sets me up and helps me gain clarity with out having to then do an extensive vocal warm up. Can’t recommend it enough. The different intensities are easy to transition between too

A singer’s best friend

This is a fabulous product!
The design and all of the attachment for various resistance of airflow fluctuation are brilliant! My new best friend to keep me in tip top shape for gigs and productions and a great teaching tool!
Thank you!

Game changer!

It's a great helping tool for every singer performer out there. SOVT exercises are known to have significant benefits on our voices. I got the pro version so I could experiment with Vara attachment and more options of blowing pressures. It certainly relaxes and comforts my voice. Warm up takes much less time now. It's like your voice gets in motion and into the right placement mush faster and more effectively. I'm really satisfied with this investment.

Hannah Howie
Amazing warm up tool

I Love using the resono pro side of stage to warm up my voice. It’s so portable and the idea of using different, measurable resistance is incredible - it’s helping me structure my warm ups much better, and helps set up my voice for a fab show. What’s more, it really regulates my breath and calms me before I step out onto stage. Highly recommend!
