If you have normal hearing in one ear and little to no hearing in the other, you already know how exhausting daily conversations, phone calls, and group settings can be. This condition, known as single-sided deafness (SSD), is one of the most common reasons people search for CROS hearing aids — and in 2026, two brands dominate the conversation: Phonak CROS and Signia CROS.
Both brands make excellent CROS hearing aid systems, but they are built differently, sound different, and suit different lifestyles. In this guide, we compare Phonak CROS vs Signia CROS hearing aids across technology, sound streaming, battery life, comfort, and price — so you can choose the right CROS hearing aid for single-sided deafness in 2026.
What Is a CROS Hearing Aid and How Does It Work?
A CROS hearing aid (Contralateral Routing of Signal) is designed specifically for people with single-sided deafness or unaidable hearing loss in one ear. The system uses two devices:
- A transmitter worn on the deaf or non-functional ear that picks up sound
- A receiver worn on the better-hearing ear that wirelessly delivers that sound
This means sound from your "dead side" is no longer lost — it's transmitted directly to your good ear in real time. Whether you're at a noisy restaurant, in a car, or on a work call, CROS hearing aid technology helps restore spatial awareness and reduces the listening fatigue that comes with SSD.
