Do you have hearing loss in just one ear? Do you find yourself constantly turning your head to hear conversations? If so, you are not alone. Millions of Americans live with single-sided deafness, and it can make daily life frustrating.
The good news is that special hearing aids called CROS and BiCROS are designed specifically for this condition. This guide explains how they work and helps you choose the best option available in the USA in 2026.
What Is Single-Sided Deafness?
Single-sided deafness means you have little or no hearing in one ear, while the other ear hears normally or fairly well. This condition can result from illness, injury, tumors, or unknown causes.
With only one working ear, it becomes difficult to locate sounds, follow conversations in noise, and hear people speaking on your deaf side. Regular hearing aids do not solve this problem, which is why CROS and BiCROS systems exist.
What Is a CROS Hearing Aid?
CROS stands for Contralateral Routing of Signal. A microphone placed on the deaf ear captures sound and wirelessly sends it to a receiver on the good ear.
This allows your hearing ear to receive sound from both sides of your head, restoring awareness and balance.
CROS is best for: People with one completely deaf ear and normal hearing in the other ear.
What Is a BiCROS Hearing Aid?
BiCROS systems work like CROS but also amplify sound in the better ear. This is useful if your hearing ear also has some hearing loss.
BiCROS is best for: People with one deaf ear and hearing loss in the other ear.
