CROS and BiCROS Hearing aids

For ‘Single-Sided Deafness’

Are you deaf in One Ear ?

Single-sided deafness is defined as un-aidable hearing in one ear, and normal hearing OR an aidable hearing loss in the other ear.

There are three main difficulties for those people who suffer complete deafness in one ear:

  1. Loss of localising sound direction – using just the one ear makes it very difficult to know where sounds have come from.
  2. Understanding speech in noise – the brain has an amazing ability to suppress out unwanted sounds, but it can only do this when listening in stereo.
  3. The head shadow effect – low frequency sounds are longer in wavelength and can travel around the head, but high frequency sounds are shorter in wavelength and are shielded by the head. And because high frequency components of speech dictate clarity this makes it difficult for people to follow conversations from their dead side without turning their head all the time.

 

CROS hearing aids may be your solution to a better life

 

CROS stands for ‘Contra-lateral Routing of Signal‘.

 

CROS hearing aids are used by those who have 1 dead ear + 1 ear with NO hearing loss.

Bi-CROS hearing aid solutions are  for those who have 1 dead ear + 1 ear WITH hearing loss.

What is the best set-up?

The best set-up depends on what works best for you, what offers the best control, and want you actually want to wear.

At present made-for-iPhone (MFi) CROS hearing aids offer the best all around control – even if you have an Android phone – so long as you can download the relevant hearing aid app you can use their app for remote control (you just cannot stream audio). Read more on MFi.

With MFi CROS hearing aids you have greater control of how much sound you transmit from the dead side, or you can easily mute the dead side if preferred. If you have an iPhone you also have audio streaming benefit.

Starkey, Signia and Oticon offer MFi CROS hearing aids.

Starkey, Phonak, Unitron and Signia offer rechargeable CROS hearing aids.

If you want invisible solution then the Signia SILK just may be what is needed – see below.

If you want maximum performance the Phonak or Unitron in-ear solution may be better for you as their ITC’s incorporate dual microphone technology (whereas the SILK does not).

We anticipate in 2020 Phonak may launch Marvel CROS – which will be able to connect to any mobile phone.

Come and see us to discuss what works best for you.

We have some free trial CROS hearing aids and we offer a 60 day money back guarantee.

TESTIMONIALS

Dear John, Just to let you know that I have already received my hearing aids back from Phonak repair. A very good service. This CROS system that you recommended has been a great success and the service received from both Phonak and yourself has been extremely professional. Thank you. Peter Bywater.


Hi John, 
    Just to let you know I am really pleased with the volume remote, it is excellent. I am also amazed that with my good ear having the volume to max or just under I can hear  quite well through my deaf ear without the Cros. As stated before this is  just incredible and do not understand why my deaf ear can hear at all, let alone well. The Cros makes the hearing really good so I will still need to wear this as well, especially in group situations. 
   So all I can say is a big thank you and hope everything continues as of now.   Obviously I will need to see you again from time to time so do I just wait until I need my ears cleared of wax again, or what ? I am so pleased I came to you and thank you for your patience. Your web attachment will mean I can purchase everything I need in the meantime. 
Cheers
John B
