Killer marketing idea - an audio product with a feature that looks like it could conceivably improve audio quality in some way, but make absolutely zero claims

Killer marketing idea - an audio product with a feature that looks like it could conceivably improve audio quality in some way, but make absolutely zero claims about whether it does or not. Don't pay for any research, don't stretch the truth in the marketing copy, just let the audiophiles buy it and argue about whether it has any effect. Everybody wins!
