Powered By the OIDO App

You can complete a hearing assessment, customize your sound settings, and adjust your hearing device in real time using a simple and intuitive interface. The app is included at no additional cost with every OIDO hearing aid.

Doctor Driven, Built for Real Life
Chief Medical Officer, OIDO
Dr. Phil Anderson is a nationally recognized ENT surgeon with over 25 years of experience treating complex hearing loss across both private practice and military medicine. A former Chief of ENT Surgery for the U.S. Army in Korea and a retired Major, he has cared for thousands of service members with combat-related hearing damage.
In civilian practice, Dr. Anderson spent decades witnessing the same pattern—patients struggling to access and afford high-quality hearing care. Frustrated by the limitations of traditional devices, he set out to create something better, drawing on his surgical expertise and academic experience to design a more effective, accessible solution.
Our Story“As someone in my 70s, I’ve always been hesitant with tech. But OIDO was surprisingly easy. The app guided me step by step, and now I can actually hear my grandkids without asking them to repeat themselves. It feels good to be part of the conversation again.”
“My mother was reluctant to try hearing aids, but knowing OIDO was guided by a surgeon gave us real peace of mind. The setup was quick, the sound is crisp, and she’s more independent now. I finally feel like we found a product that actually understands her needs.”
“I’ve tried multiple hearing aids over the years. OIDO is the first one that just works. No constant fiddling, no waiting for appointments. It’s clear someone with real medical experience designed these. The clarity in restaurants and on calls is incredible.”

FAQ
Navigate to our dedicated FAQ page for more in depth information!

How do OIDO hearing aids work?
OIDO hearing aids use advanced speech processing to enhance voices while reducing background noise. They’re designed to be custom-fitted in minutes using the OIDO App, so you get clear, natural sound without the need for appointments.
Do I need to see an audiologist?
No! Oido hearing aids are over-the-counter (OTC) and designed for mild to moderate hearing loss. You can take a hearing test and configure them right from your smartphone. If you have severe or sudden hearing loss, we recommend consulting a doctor.
How long does the battery last?
A single charge provides up to 24 hours of use, and the portable charging case extends battery life up to 96 hours, so you’re always ready to go.
Can I stream music and calls?
Yes! With Bluetooth 5.0 connectivity, you can stream calls, music, and other audio directly from your smartphone.
Are OIDO hearing aids comfortable?
Absolutely! Designed to be lightweight and discreet, they offer an all-day comfortable fit—so you can focus on life, not your hearing aids.
