It sells razors
How about a vinyl record player with 5 needles? Each needle should hit defects and dust specks differently. You send the 5 signals to the cloud, use AI to identify and remove clicks (identify the song and replace it with a CD rip), run it through some 1970s audio enhancers, blockchain something-something, subscription-stream the result back to the listener's cellphone, then finally play it into the listener's upcycled hand carved wood shell Bluetooth headset. Wait, 5 disposable needles!
