The BELTBOX  is a fabulous answer for both singers and non-singers.  My executives and business professionals will often express their frustration at not being able to practice their presentation in the confines of the office space without others hearing them.  The BELTBOX disrupts the self-conscious patterns and concerns of others hearing you and is the perfect answer to getting used to the sensation of speaking and singing while muffling the sound.

Tip: While using the device ensure you are not holding back or compensating your voice.
