ADV. Eartune Fidelity custom-fit ear tips are made from your bespoke ear impression - designed to fit perfectly only your ear canal. Proudly made in the USA.

Not necessarily. If you have a medical need pertaining to your ears, then see the appropriate doctor or specialist. Otherwise, you can make an appointment and the licensed individual will assess your ear canal during the impression appointment.

Itchy ears can mean multiple things. The first thing you want to do is to clean your Eartune Fidelity tips with soap and water to ensure their cleanliness. Don’t use rubbing alcohol or harsh detergents as they can break down the silicone over time.

A little bit of soreness is normal in the first week of wearing the Eartune Fidelity tips. Your ear canal should get accustomed to them within a week. However, if the soreness persists please email us HERE.

The Eartune Fidelity tips are highly recommended for this use since they will improve noise isolation.

Place the order under your name and leave us a note; and send us his/her ear impressions.

Tech-care Ear-gel is a water-soluble gel that is safe to use in the ear canal. It’s meant to help the custom tips slide into your ear canal easily. Not everyone needs it so try to insert the Eartune Fidelity tips without it first and only use as needed.

Place a small amount of Tech-care Ear-gel around the tip (do not cover the sound bore) to help lubricate it for insertion.

No, after a couple uses, your ear oils will naturally lubricate the Eartune Fidelity.
