Resono Flex (Clearance)
Free Your Voice With Bubbles
Water bubbling technique is a type of semi-occluded vocal tract (SOVT) exercise that involves blowing bubbles through a straw submerged in water. It is highly recommended by medical professionals as a recovery and rehabilitation intervention for intricate muscles of the voice. The technique provides bio-visual feedback from the bubbles, allowing you to see your respiratory output and identify when there's either too much or too little effort applied.
Plus, you also get alternating pressure waves from the bubbles, which creates an internal massage for your vocal muscles that helps with recovery and rehabilitation (and is great as a warmup and cool down too).
Seal the Deal with Every Note
Our uniquely designed mouthpiece creates the perfect seal for your lips, ensuring you have total control over your vocal tract oscillation, enabling the therapeutic "massage effect" for vocal muscles.
A Massage for Your Voice
With the Resono Flex, you will literally feel your entire vocal tract (including your cheeks) oscillate / pulsate with the alternating pressure provided by the device - that means it's working to unlock the true potential of your voice.

How do I close the Flex?
From the factory, the Flex will be shipped to you in its open position. This is normal. The Flex has been designed to be fully openable to allow you to clean the entire inside surface fully and prevent any buildup of nasty stuff.
The Flex takes only a few seconds to "click" back together. The action is a one-thumb-over, one-thumb-under kind of technique, ensuring to click the halves together to create a deal.
The process should only take 20-30 seconds. You can find full guides for this in the resources page if your account.
Customer Reviews
I was able to hear a difference, I had been using a straw but smaller. The size helps with air, and the flow, but I love it!!!
This product connects my singing students to their diaphragm, builds stamina and regulates the air flow both below and above the vocal folds. I had good success with everyone who has used one. Aperture bigger than a drinking straw and just the right amount of air flow for singers. Price is great too. Can be difficult to clip together. Younger students need help. But I recommend to all my pupils.
Great for vocal reset and great for developing vocal strength and stamina.
Received the bundle with the vocalitea, the resono flex and the voice journal as a Christmas present, love anything to do with vocal health and this bundle is amazing! The tea is lovely, journal is so well thought out and can’t wait to use during sessions, and the response flex is so brilliant for strengthening and warming up my voice!
I find the product very helpful in repairing my damaged vocal chords. My specialist from speech and language therapy was very impressed with the item too and will recommend it to her patients. It was however very fiddly to connect it together but I managed using a thin metal nail file.
Singing Straw therapy was recommended to me by a good friend of mine who is a professional singer with two number one’s in the classical album charts!
I lost my voice 7 weeks ago after catching Covid. I have never known anything like it I couldn’t even speak.
I am a professional singer songwriter and it felt to me like I would never sing again!
I purchased the Resono Flex a week ago and use it daily and from a watery gravelly voice I am gradually getting my voice back to something that I recognise as being ‘my voice’
I can strongly recommend it!

I did have a great deal of trouble at first “zipping” back up my straw but
once you’ve got the knack all is fine.
Very easy to use, with much better flexibility in back-pressure obtainable than my previous (narrower) singing straw. Prompt delivery and have recommended it to all my singing friends! A little fiddly to nip it together, but good to have opening option for cleaning.
I totally recommend this tool. The opening makes cleaning it thoroughly so much easier than in any other straw of this kind that I have had. The markings on the side are also really helpful to adjust it for different exercises.
Been using this for a few weeks now and think it’s had a great impact on my warm ups and cool downs. Certainly helped me when singing
