So you would like to take phone calls in an open space while maintaining some level of privacy. Hushme is a smart voice mask for smartphones that promises just that. It has headset, passive, and active modes. It connects to your smartphone via Bluetooth and performs like a regular hands-free headset.
In passive voice muffling mode, Hushme covers your mouth, so people won’t be able to decipher your words. In active voice masking mode, the device generates masking sounds to protect your privacy. The companion app comes with various masking sounds but you can upload yours. What do you think? Is this a good idea?
