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.

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"

Resono Pro

Bianca L.
I’m very impressed

I am a trained singer with many years of choir, bands, and lessons with different teachers under my belt. However haven’t done any music in about 6 years.

After just having read the book, checking out a few videos, and playing around with the Resono Pro with and without water for 2 days, and I was able to get that laser-focused buzzing resonance in my voice (the one classical and opera singers aim for) that I always had a hard time pinpointing consistently throughout my whole range, even with lessons. I was astonished. I felt as if I hadn’t had a six year break when I tried a song just to see what happened, the sound and feel were incredible. Far more polished that I could have ever hoped for while being so out of practice.

Of course, the technique from past lessons helped, but still, it felt almost miraculous. It’s also really a much-needed boost to my confidence after this time of not singing, which is amazing in itself. I can see it being invaluable for recording and performing.

A tiny issue is that the silicone mouthpiece has casting lines on it from the production mold that are just a bit too big, but if I hold it horizontally with the lines parallel to my lips, then that’s not a big issue. However I hope it’ll be addressed in future production to improve the feel of quality.

All in all, I’d had my eye on this for at least a year and finally took the plunge even though, since I hadn’t been singing for so long, it felt like an extravagance. But I am glad I did! I’m looking forward to working more with it and seeing how my voice returns, strengthens, and improves in a healthy way.

Superb service, quality product

Excellent fast customer service in establishing compatibility and correct product choice.Rapid delivery.

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!!

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
