If you're paranoid that someone is always listening in on your conversations, I suggest you consider forking over some cash for the Yamaha VSP-1 noise generator. This helpful device masks your voice so that your nosy neighbors will stay out of your business permanently.
An exclusive Japanese product, the Yamaha VSP-1 noise generator would also be incredibly useful in environments that require extreme privacy such as banks and meeting rooms. With sounds such as that of a babbling river, a quiet forest and even urban clutter, it will ensure that you can talk freely without fear of being overheard.
In fact, the Yamaha VSP-1 noise generator masks up to 89% of a conversation. It also features a rather discreet design. It is priced at about $1,200 (¥105,000).
