SINGLE-SIDED DEAFNESS · CROS SOLUTIONS
Deaf in one ear? There is a proper solution
If one ear no longer responds to sound — suddenly or gradually — a CROS system quietly sends sound from that side to your hearing ear. Conversations stop happening on your “wrong side”.

What single-sided deafness feels like
People with one unaidable ear describe the same moments: restaurants where you must grab the “good seat”, walks where a partner keeps ending up on the wrong side, group chats where whole sentences vanish.
Why one ear matters so much
Two ears tell your brain where sound comes from and lift speech out of noise. Lose one side and localisation goes with it — and noisy rooms get much harder.
How CROS solves it
A discreet transmitter sits on your unaidable ear and streams sound wirelessly to a device on your hearing ear. You hear your “deaf side” again — through your good ear.
And if your better ear needs help too
That is BiCROS: the same transmitter, but the receiving ear’s device also amplifies. We test both ears properly and fit whichever your hearing actually calls for.

WHAT HAPPENS NEXT
From first appointment to hearing both sides
1. Proper assessment — £59
A full ear examination and pure-tone audiometry of both ears — because the right solution depends on what your better ear can do.
2. Honest recommendation
CROS, BiCROS or something else entirely — if a different route would serve you better, that is what we will say. No pressure, ever.
3. Trial in your real life
Wear the system at work, at dinner, on your usual walk — the trial decides, not us.
Sudden hearing loss in one ear should always be checked urgently by your GP or A&E first — ideally within 48 hours. Once the medical side is handled, we are here for the hearing side.
GOOD TO KNOW
Single-sided deafness questions, answered
What is a CROS hearing aid?
CROS stands for Contralateral Routing of Signal. A transmitter on your unaidable ear sends sound wirelessly to a device on your hearing ear — so you hear what happens on your deaf side through your good ear.
What is the difference between CROS and BiCROS?
CROS is for people whose other ear hears normally. BiCROS is for people whose better ear also needs some amplification — the receiving device works as a hearing aid too. Your hearing test tells us which fits.
How much does a CROS system cost?
We fit CROS solutions across Signia, Phonak, Oticon and Widex, with transmitters from £1,347.50 (for example the Signia CROS IX) paired with the hearing aid that suits your better ear. We will quote your exact combination clearly before anything is ordered.
Will CROS restore hearing in my deaf ear?
No — and anyone who tells you otherwise is not being straight with you. CROS reroutes sound so you stop missing conversation on that side; the hearing itself is not restored.
I suddenly lost hearing in one ear — what should I do?
Treat it as urgent: see your GP or A&E promptly, ideally within 48 hours, as early medical treatment matters. Once you have been seen medically, book in with us to talk through the hearing solutions.
Can I try CROS before buying?
Yes — wear your recommendation in the situations you find hardest before you commit. There is no obligation.
