You would need to pair each On each time.
I’ve been told that if the On’s are linked together in a Network, then what you’ve described won’t work as the On’s ‘would know’.
The only hack to get around it, is to link 1 x On to 1 x HA only and not both. Won’t really work for people who have a worse ear, I guess or only 1 x HA / BAHA / CI anyway.
Interesting topic.
I think roger table mic ii maybe an alternative to pass-around mic, with the table mic ii you don’t need an expensive roger X 02!
Another alternative maybe something like ceiling hung microphones in a classroom settings, think UK house of parliament as an example.
For the price of a new Roger On In… If you shop around eBay, especially in the states, you could probably pick up, a couple of Pass Around Mic’s, 2 Roger X (Type 2) Receivers, making sure you check with the seller, that the serial numbers do not predate 1744, (anything before 1744 is older technology, and will not work with Marvel, Paradise or indeed Lumity) and pick up a Roger Touch Screen, and probably have some change? My Pass Around, cost me the princely sum of £10…!!! My cheapest (Type 2) Receiver, was 6months old according to the manufacturers date stamp on the box, twas £56…!!! I also got another (Type 2) for £97… The other pair of (Type 2) I have, cost me approximately £200 each… They cost new @ £600 each! My most expensive was my first purchase (Type 3) bought new @ £350, this was long before I became clued up, I believe the other (Type 3) was £79 or thereabouts? Roger Touch Screen was approximately £300, and it was in pristine condition, they are around £702 with VAT taxes, or £585 without VAT, new here in the UK… Yes, there are bargains to be had, via eBay, if you are patient, and wait for them to come along, and in the present economic downturn, it is predominantly a buyers market… TBVH, I could have bought new, and perhaps not quite bankrupted myself? A healthier bank balance was my ultimate aim, buying new would not have given me a better hearing outcome, to me, especially with regards to Roger X Receivers, it’s only the licenses you need, the actual Roger X becomes a very tiny paperweight…It’s useless for anything else, once the license is removed! Cheers Kev 
Touchscreen are around £550.00.

I see them on eBay in the US for less then $200 now.
Thank you @Zebras, apologies, I will amend that mistake! It was last year, that I checked the price… Just checked Connevans, just now, £702 including VAT, or £585 without VAT… Still expensive! Cheers Kev 
I have the lumity on order. Oddly, they were back ordered but I hope that is due to their popularity. I have been told I am a candidate for cochlear on the left side with a 40% recognition on that side. I have just about given up hope for a stem cell solution. Have you heard anything new on this? My problem is a distortion that sounds like static and crackling and is far worse in noise, especially with women and children. Recognition is noticeably higher with men’s voices. I am suppose to meet with the surgeon/cochlear specialist in 2 weeks. I am 69 so I don’t know how long I can wait. Good luck on your effort.
Yes very expensive considering the Touchscreen has been out for years. Not sure exactly when but it’s quite old now.
Did you know that deaf people can claim VAT relief? I’ve had VAT relief from Boots and Connevans.
Wow just looked on You Tube. There are videos about the Touchscreen from 2016. They really need to bring out a new one.
Hadn’t realised it was as old as that.
Yeah Ruth, I am sure Sonova will have something in the pipeline, most likely a, Touch Screen V2? I agree, it is expensive for outdated tech though! Yes, I was aware, of the VAT waver, but some products are not exempt! Seems to be a gray area? I usually won’t buy from Connevans, if it’s plus VAT, in fact, I have an extreme aversion to that word, and I will have a borderline allergic reaction to VAT 
I just feel, you should never pay VAT on anything to help you with your hearing loss, or any other disability! Cheers Kev
I’m on the verge of cochlear implants, but I’m hanging on for two reasons:
1 Cochlear implant technology is improving rapidly - much faster than hearing aids in general.
On the other hand, if you’re having real problems and don’t want to wait, getting a cochlear implant in your worst ear is actually a great idea because your brain will combine the sound from both ears, improve word discrimination and sound more natural than a cochlear implant in both ears. If you don’t get enough improvement in word discrimination, you can always have a cochlear implant in the other ear later.
My friends (set of twins) have done this.
Altho they were children at the time and here in the UK, they were allowed 2 x CIs as children. Their parents only got 1 x CI in case there was improvement in technology/research to help their other ear with stem cell etc.
Only issue is, they’ve been waiting 36 years and could be waiting another 36 years or more.
Will it ever happen in a life time?
Silly question, but what qualifies as being deaf in the UK?
Pretty sure any deafness range.
Boots just automatically say I qualify and Connevans, you have to mark that you’re claiming relief due to ‘hearing’.
