How should a hearing-aid brand talk about silence?

Dear Marrow & Vane, Every hearing-aid brand promises louder and clearer. Our customers tell us they are tired of noise, and that they don’t want more of it. Our competitors sell volume, clarity and an invisible fit. So do we, to people who put off hearing tests for years. Our newest model has one feature nobody asks about: a switch that turns the room down and one voice up. Our shops still sell it last, after battery life, yet most customers end up choosing the model for that switch alone. How should we talk about silence? The Marketing Director, Quietpost Audio
