Hearing Aids Fitted Around Your Life
Today's hearing aids are small, often rechargeable, and can stream phone calls and TV straight to your ears. But the device is only half of it. How well it's fitted decides how well you hear.
At Hear4U, Robert Cousins (License #HA8055) fits hearing aids from 7 major brands and checks every fitting with Real Ear Measurement, so the sound is set for your ears, not an average ear.
Types of Hearing Aids
There are four main styles. We'll help you pick the one that fits your hearing, your ears and your hands.
Behind-the-Ear
(BTE)
Sits behind the ear, with a tube or custom earmold in the ear. The most power, so it suits mild to profound hearing loss, and it's the easiest to handle.

In-the-Ear
(ITE)
Custom-made from an impression of your ear and fills the outer part of the ear. Easy to put in, with room for larger controls. Suits mild to severe hearing loss.

Receiver-in-Canal
(RIC)
The most popular style today: a small case behind the ear, with the speaker in the ear canal. Light and natural-sounding, and usually rechargeable with Bluetooth. Suits mild to severe hearing loss, depending on the speaker size.

Completely-in-Canal & Invisible-in-Canal
(CIC) & (IIC)
Custom-made to sit deep in the ear canal, so they're hard to see. Some are too small for Bluetooth or rechargeable batteries. Best for mild to moderate hearing loss.

How Your Fitting Works
Maintenance and Care Tips
A few minutes of care each day keeps your hearing aids working well:
Cleaning
Wipe them daily with a dry cloth and brush wax from the speaker and microphone openings. Change the wax guard when the sound gets weak.
Storage
Keep them in their case or charger, away from heat, moisture, pets and children.
Battery Care
Charge rechargeable models every night. With disposable batteries, keep spares and open the battery door at night.
Troubleshooting
Weak or no sound? Check the wax guard and dome first. Still not right? We clean and repair hearing aids, including ones bought elsewhere.
