I just discovered to my chagrin that the M90-R is not compatible with the M90-RT. I have a set of M90R hearing aids, but one of them makes annoying pops every so often, which basically makes it annoying enough that you probably wouldn’t want to wear it. So I bought an M90-RT on eBay, figuring it would mate with the good M90-R, but unfortunately, Target says it is not compatible. I suspect I could use the two together, but they won’t share Bluetooth, but I haven’t tried. Interestingly enough, Target also claims this one is a Trial, but it doesn’t say trial on the side like my other trial HA. I also know that the M90-R is not compatible with the M70-R, which I used to have, but passed on to a friend. If anyone would like to swap an M90-R for an M90-RT or vice versa, I’d be happy to oblige you. Or if anyone knows a way to make them “compatible”, that would be great too! And anyone having any info on why Target thinks the M90-RT from eBay is a Trial HA, but it doesn’t say so on the side, I would be interested in that too.
Thanks,
Rob
Yeah what a bummer, I would of thought the T was for tcoil which would of worked, but I’ve seen that before no trial written on the housing,and yep you could use them independently but of course that defeats the purpose of using them, as in the extra features, what about returning for item “not as described” I believe @PeterH has tried grouping different models before, hopefully he’ll have some advice.
I haven’t had any success in pairing different models. I can certainly understand why M70 & M90 won’t pair due to the differing elements of Autosense 3. Maybe the telecoil only being in one aid, presents a similar issue??
Running them separately, as you say, will mean Bluetooth will be only to one HA. However, they’ll work fine with both Roger and TV Connector.
I know you can link a Phonak Sky L70 SP and a Phonak Sky L70 M together to work as one.
You can’t link a NHS Phonak Nathos Nova M and a Phonak Naida M70 SP together so that is why she got the kids set up and better Aids!!
My friend has the set up.
The MyPhonak App also works fine.
I need to try to see exactly what happen when I try to connect to both devices. The MyPhonak app is supposed to work with both. I only tried Target, and it would only work with one HA or the other.
This one surprises me. Both use the M70 version of Autosense3, and both have telecoil. I wonder if Sky Bolero M70 M & Sky Naida M70 SP will pair? I shall give it a try.

I’m thinking this is because target uses a “hidden feature” for those NHS with a code, without the code the NHS models don’t show up in target, target may be getting confused when both are presented?
I believe this is true. I understand NHS Audiology enter a Custom code on installation of Target. Without this code, they can’t be accessed.
I will now try the Sky Bolero M70 M (the M bit is important for this, as only the “M” has the Telecoil, whereas the rechargeable versions don’t) and the Sky Naida M70 SP.
These do both pair, although Target saw some mismatch so I had to choose one side, to proceed. I’m sure whatever that was, could be ironed out in the fine tuning.
Conclusion for pairing Phonaks together in Target:
- Autosense must match in Version (3-6)
- Autosense must match in Tech (30-50-70-90)
- Things like Telecoil availability must also match. This may include motion sensor in Lumity, which isn’t available in all models. I can’t test this. It’s also clear the NHS thing is an issue too.
Edit:
4) They may also need to use the same App (MyPhonak or MyPhonak Junior)
Good work Peter, thanks for letting us all know.
You won’t be able to pair a Naida M70 SP and a Sky M70 M either.
The name has to match as well.
All a bit confusing.
They did pair though 
Edit: I mis-read this
Just a thought on this @Zebras
Maybe they won’t pair because they don’t use the same App?
The Naida and Sky Lumity use the same App (myPhonak) and the same pop up window says they can’t be linked.
