Water resistance training you can take anywhere.

The VoxFlex Vocal Tube is one of the simplest and most effective tools for your voice. Fill the bottle with water, place the tube inside and hum or sing through it. The water creates gentle resistance that helps your vocal folds work efficiently and without strain. The bubbling also has a soft massage effect that releases tension and leaves your voice feeling balanced and free.

The bottle makes it practical. You don’t need to look for a glass or a cup, so you can warm up in the car, backstage, in a hotel room or at home, then close it and pack it away.
