Phonak CROS B Hearing Aids (BTE)

Winter 2021 Update:  Soon Phonak will be releasing their Phonak CROS P hearing aid in the UK, which is compatbile with Phonak Paradise.  This will supersede the CROS B BTE styles, but not the ITE models.  View CROS P here

2021 Update:  Phonak CROS B BTE styles are now available in rechargeable - the Phonak CROS B-R hearing aid.  So now you can enjoy the freedom and confidence to have hearing from both sides without the hassle of batteries. 


Phonak CROS B Hearing Aids (BTE) - An introduction

Phonak CROS B is the CROS device using Phonak Belong technology. When CROS B and an Audéo B hearing aid are fitted together, it enables clients with single-sided deafness to hear speech more accurately and better able to follow conversations from whatever direction.  Using Binaural VoiceStream Technology the CROS B wirelessly sends the sounds from the ear that has no hearing over to the better side.


Phonak CROS B Hearing Aids (BTE) - Stereo Zoom

Phonak uses their integrated StereoZoom system which has proven successful at binaural beamforming. It creates a very narrow beam to focus in on single voices when in a crowd. This can deliver much better speech understanding when in background noise.  The CROS B can be either rechargeable or use normal batteries. 


Key features of Phonak CROS hearing aids (BTE)

The Phonak CROS is a specialist hearing instrument. It is specifically designed for people with no hearing at all on one side. The CROS aid is worn on the “dead” side and transmits sound to a hearing aid worn on the other ear. Please note, another Phonak hearing aid is required on the other ear to enable the sound to be received.

If the “good” side is near normal then the lowest technology hearing aid can be worn. If the “good” ear is impaired then higher technology hearing instruments can be considered. This configuration is called BICROS and may cost more if you choose a higher technology “receiving” hearing aid.

The Phonak CROS system can be paired with any wireless capable Phonak hearing aid compatible with the Belong range.  As they are wirelessly capable, they can be connected to a number of Phonak wireless accessories.


Phonak CROS B hearing aids (BTE) accessories include:

  • Phonak Compilot II – Streamer that is worn around the neck.
  • Phonak Compilot II Air - Discreet and stylishly connects your hearing aids to smartphones for Bluetooth-enabled music sources.
  • Phonak TV Link S – TV transmitter/compilot charger.
  • Phonak PilotOne II – Basic remote control.
  • Phonak DECT II - A cordless phone that directly transmits phone conversations to both hearing aids.


Any additional features would depend on the model of hearing aid you choose to pair with your CROS system.  View the Phonak CROS B custom ITE models here


Cost of Phonak CROS B hearing aids

The pricing for Phonak CROS and BICROS hearing aids all depends on the technology level, as you need both sides which are priced separately.


For example:

  • Phonak CROS B £895 with Audeo B30 £695 = £1590
  • Phonak CROS B £895 with Audeo B50 £1095 = £1990
  • Phonak CROS B £895 with Audeo B70 £1395 = £2290
  • Phonak CROS B £895 with Audeo B90 £1695 = £2590

Is this the best model for me?

If you are looking at this page then it is likely that an audiologist has suggested that you purchase this particular hearing aid, so is this the best model for you?

In general, any audiologist will always be recommending to you the model that best suits your needs. Here is a useful check list to make sure that is the case.

  • Audiologist level of knowledge. The audiologist you have seen will hopefully have a wide knowledge of all available hearing aids, however some will only be familiar with a small number of brands and therefore may not really be in a position to know which model is the best for you. It is OK to challenge their recommendation and ask them to justify why this particular brand is the one for you.
  • Do research. Read about the hearing aid that was recommended. Does it seem like it will suit your lifestyle? Does it have more or less features than you need? 
  • Be aware of sales targets. Many high street retailers have specific tie-ins to a particular manufacturer/brand. The hearing aid they have suggested may still be the correct one for you, but do your research so that you know why they might have recommended it.

If in doubt, feel free to give us a call. That's what we're here for.

Do I need one hearing aid or two?

If you have a significant hearing loss in both ears, you should be wearing two hearing aids. Here are the audiological reasons why:

Localisation. The brain decodes information from both ears and compares and contrasts them. By analysing the miniscule time delays as well as the difference in loudness of each sound reaching the ears, the person is able to accurately locate a sound source. Simply put, if you have better hearing on one side than the other, you can't accurately tell what direction sounds are coming from.

Less amplification required. A phenomena known as “binaural summation” means that the hearing aids can be set at a lower and more natural volume setting than than if you wore only one hearing aid.

Head shadow effect. High frequencies, the part of your hearing that gives clarity and meaning to speech sounds, cannot bend around your head. Only low frequencies can. Therefore if someone is talking on your unaided side you are likely to hear that they are speaking, but be unable to tell what they have said.

Noise reduction. The brain has it’s own built in noise reduction which is only really effective when it is receiving information from both ears. If only one ear is aided, even with the best hearing aid in the world, it will be difficult for you to hear in background noise as your brain is trying to retain all of the sounds (including background noise) rather than filtering it out.

Sound quality. We are designed to hear in stereo. Only hearing from one side sounds a lot less natural to us.

What are the benefits of rechargeable hearing aids?

For most people, the main benefit of a rechargeable hearing aid is simple convenience. We are used to plugging in our phones and other devices overnight for them to charge up. 

For anybody with poor dexterity or issues with their fingers, having a rechargeable aid makes a huge difference as normal hearing aid batteries are quite small and some people find them fiddly to change.

One downside is that if you forget to charge your hearing aid, then it is a problem that can't be instantly fixed. For most a 30 minute charge will get you at least two or three hours of hearing, but if you are the type of person who is likely to forget to plug them in regularly then you're probably better off with standard batteries.

Rechargeable aids are also a little bit bigger and are only available in behind the ear models.

Finally, just like with a mobile phone, the amount of charge you get on day one is not going to be the same as you get a few years down the line. Be sure to ask what the policy is with the manufacturer warranty when it comes to replacing the battery.


Are behind the ear aids better than in the ear aids?

For most people, the answer is yes. But it's never that simple.

The majority of hearing problems affect the high frequencies a lot more than the low ones. Therefore open fitting hearing aids sound a lot more natural and ones that block your ears up can make your own voice sound like you are talking with your head in a bucket. Therefore in-ear aids tend to be less natural.

However the true answer is we can't tell until we have had a look in your ears to assess the size of your ear canal, and until we have tested your hearing to see which frequencies are being affected.

People with wider ear canals tend to have more flexibility, also there are open fitting modular CIC hearing aids now that do not block your ears.

There is also the age old rule to consider, that a hearing aid will not help you if it's sat in the drawer gathering dust. If the only hearing aid you would be happy wearing is one that people can't see, then that's what you should get.

Most people can adapt to any type of hearing aid, as long as they know what to expect. Have an honest conversation with your audiologist as to what your needs are.

What are channels, and how many do I need?

Generally speaking, six or more. Unless it's none at all.

The number of channels a hearing aid has is often a simplistic way an audiologist will use to explain why one hearing aid is better than another, but channels are complex and it is really not that straightforward.

Hearing aids amplify sounds of different frequencies by different amounts. Most people have lost more high frequencies than low and therefore need more amplification in the high frequencies. The range of sounds you hear are split into frequency bands or channels and the hearing aids are set to provide the right amount of hearing at each frequency level.

Less than six channels and this cannot be done with much accuracy, so six is the magic number. However, a six channel aid is typically very basic with few other features and is suitable only for hearing a single speaker in a quiet room. The number of channels is not what you should be looking at, it's more the rest of the technology that comes with them.

As a final note, different manufacturers have different approaches. One method is not necessarily better than any other. For example some manufacturers have as many as 64 channels in their top aids. Most tend to have between 17 and 20. One manufacturer has no channels at all.
