Hear every word again. Nobody will see a thing.

Core One Pro helps you go from "What did you say?" to hearing every word, without a $4,000 clinic bill or a smartphone app, using a tiny hearing aid that hides inside your ear.

Sound familiar?

• You ask people to repeat themselves.
• Others say the TV is too loud.
• In restaurants, voices turn into noise.
• The hearing aids you've seen cost thousands, need a clinic, and sit on top of the ear where everyone can see them.

Core One Pro sits inside your ear, makes voices clearer, and costs $299 for the pair. If you're not hearing better within 100 days, you get your money back.

• Weighs 1.2 grams. Nothing behind the ear.
• No app, no phone, no batteries to change.
• Made for mild to moderate hearing loss.
