Japan has a device that will help you improve your karaoke skills in 3 minutes

Struggling to hit those high notes when singing karaoke? Leave it to Japan to invent a handy little device to solve this problem. Known as the Proidea High Tone Trainer, this mind-boggling device can apparently help increase your vocal range by an octave. All you have to do is let it sit in your mouth for three minutes a day.

So how does it work? There is no need to strain your voice or practice actual singing. The trainer is designed to raise the soft tissue on the back roof of your mouth. This is the tissue that stretches when you sing, allowing you to produce higher notes.


Admittedly, the device looks a bit ridiculous. But with regular use, the trainer could help shape this soft tissue in your mouth, and you might be able to achieve those highs that were once impossible. Plus, you only need to set aside three minutes of your day. How hard can that be?

We cannot verify whether any of the claims actually work. But if you want to give it a try, the Proidea High Tone Trainer is available online for NLG 2,980.
