We've all been there. Needing to go through vocal exercises before auditions but not wanting to disturb those around you.
That's where your BELTBOX comes in - It muffles your voice up to 30 dB but still allows you to hear if you are in the right key!
Use your full voice and it sounds like a whisper!
You can also feed in a microphone for quiet conversations or gaming.
