Phonak CROS II – The smart solution for single-sided hearing

This movie is for anyone who wants to learn more about single-sided hearing and how the Phonak CROS solution helps to overcome the challenges resulting from it. An artificial head is used to simulate the different hearing conditions and let you experience how real Phonak CROS devices sound. Finally, you can experience the additional benefit of the latest Phonak CROS II compared to the previous Phonak CROS.
Please wear headphones when watching the movie. If you have single-sided hearing, make sure that the left headphone is on your better hearing ear.

There are several things this video does not mention or address. The CROSS II is a good system for single sided deafness but it has it’s cons the Mfr (like all of them do) doesn’t like to discuss. I am not an expert or an audiologist, I am someone who has struggled with Meniere’s Disease since 2005 and experienced first hand several of the Phonak brand hearing aids over the years.

First they all should all be bluetooth and work with phone app’s for user adjustability but only one of the new CROSS II models is yet their advertisement campaign makes a huge deal over bluetooth connectivity. I mention this first because having Meniere’s Disease the CROSS II system helps in a lot of situations but does not help much for phone calls and only the bluetooth model works well paired with the phone app that allows wearers to adjust them. Also having Meniere’s my hearing fluctuates in both my affected ear and my good ear which is also likely going to be an affected ear as early symptoms are already happening. I pretty much rely on the speakerphone on my S8 because of this and I have to take them out often at places like the mall where mindless blabbering echoing off poor acoustics is downright painful. So having the freedom to adjust MY hearing aids to suit MY preferences and not have to wait months to get an appointment to see my audiologist and have them tweak the sound profile to where I think it might be better even though it’s in a soundproof lab would be a very liberating thing to have.

Second, it sounds easy in premise to get fitted for a set of these and just go from there but for vestibular disorders like Meniere’s Disease there is no helpful info handed out or given that the hearing aids can trigger vertigo attacks. If your equilibrium is suffering from a severely damaged organ then it is already struggling to compensate. With the addition of sound coming from your affected side being mixed in with the sound coming into your good or healthy side this can overload your senses. The result is too much sensory input on the good side overwhelms your equilibrium which is already compromised and a vertigo attack occurs. I will say this is much more likely in the first few months as your brain can adapt to quite a lot of change gradually over time.

Third is the dramatic improvement over the CROS I system which had only volume up control on one hearing aid and volume down on the other yet zero control over treble, bass, and echo. With the CROSS II system you can adjust the volume of each hearing aid independently of the other. This is extremely important because most Audiologists treat patients with hearing loss as small incompetent children. I say this because whatever sound profile is initially loaded into your hearing aids during fitting is rarely the sound profile hearing aid users would choose if given the appropriate amount of time to see where they want their hearing aids set at long term. It is extremely ridiculous in the modern day of technology we live in that hearing impaired patients are typically hindered by the very audiologists they have to make an appointment with just to get hearing aids adjusted to feel more comfortable in sound quality to the wearer. So with the CROSS II I can now at least turn the bad side up or down to feel even with my good side which is not a fixed constant.

So to sum it up, the CROSS II system is a huge step in the right direction but Phonak could still improve on several of the current models.

Seriously? You don’t mike the presenter in this video? Seriously?

Apentogo says:

3:25 thats exactly how it feels/sounds, exept worse because of outside noise interferences.
nvm lol said it few sec later^

Kakoli Sen says:

Single-sided hearing comes with loss of direction of sound. That might be rectified by a CROS. Cons- wearing aid in the good ear too.

Lorenzo Notarianni says:

This is an excellent demo.

Brett Stevens says:

I’m getting a 3cm acoustic neuroma removed soon. unfortunately there’s no way they’re going to be able to salvage hearing in my right ear because of it. This looks so promising, and I’m so thankful I live in an age when tech like this is becoming the norm.

Darrell McMillan says:

I’m picking this system up in a week and a half and I’m really excited about the possibilities. I’m near-deaf in my right ear due to Meniere’s Disease.

CrowdPleeza says:

To those with a cros aid. How has having one affected your job experiences? Has it expanded the types of job environments that you can work in? What about jobs where they provide hearing protection like ear plugs at factories and plants? I’d think that you can’t wear the cros and ear plugs at the same time. Has something like this affected your job options?

great video, very helpful, thanks!
