How do I find an audiologist?

1of1 Custom has a network of approved audiologists across the states that our customers can visit. To find your nearest audiologist, call us at 646-559-5642 or email info@1of1custom.com.

Additionally, any audiologists, that aren’t included on the 1of1 Custom network providers list can make impressions. You will take the impressions away with you and ship them directly to 1of1 Custom with your information (Name, phone number, address, what you are purchasing.)

The ear canal almost always points towards the top and back of your head. To insert into your ears, place the flat surface pointing upwards, twist and apply pressure around the bend in your canal. You should feel the mold slide into place. The indicator dot will be on the front side and bottom of the plug.
