Your KS10 are Phonak Bluetooth Classic aids
The list of devices you posted is similar to the devices on my Windows 10 laptop. These are BTC devices. Your hearing aids are communicating with your computer using BTC, not BLE Audio.
Thanks for explaining the terminology of LE Audio.
Here is my Bluetooth Stack in Win 10 with BT 4.2
I require no dongle accessory to receive stereo sound.
Isn’t stereo, directed to the right hearing aid, and then transmitted by it to the left,
what LE is all about? In my reading of BT 5, the principal difference they cite is
extended range.

Totally in agreement with you. Also, macOS doesn’t have Apple’s MFI too, Apple is probably going to be implementing LE Audio in macOS 14 and iOS / iPadOS 17

Bluetooth Classic is a power hog and horribly inefficient like you mentioned, it relays the data from one to another, that is not ideal and causes high power consumption…
LE audio fixes that by isochronous channels which basically transmit/synchronizes 2 devices independently …

Thankyou !
Yes, it is a power hog.
I’ll have to wait for my KS10’s (which still power up ok) my laptop and my cellphone to all go obsolete. My hearing impairment was such that the restoration of stereo music was reason enough to treasure the KS10’s.
Can’t find this App on my iPhone which is a real shame.
Think this is an iPhone version? Not 100% sure.
Don’t think it works with Windows tho. Only Mac.
I don’t have an iPhone or Mac so can’t give you any useful input. (I probably couldn’t even if I did have those devices).
This would be wonderful if using a BT toggle to connect the laptop to More 1 HA’s. This method of connectivity is simple and fast.
I have Oticon More 1 HAs. I have tried connecting them to my computer 3 ways - a simple Bluetooth 5.3 USB dongle (yes, Win 10 has Bluetooth 5.2 support), a Bluetooth 5.3 USB audio transmitter, and a Bluetooth 5.2 transmitter that connects to the 3.5mm audio out port. In the 1st case I can connect my HAs to the computer, but because there are no drivers for the HAs in Windows, it just puts them in Other Devices, and you can’t use them for audio output. In the other 2 cases the other devices don’t even see the HAs when trying to sync them. All dead ends. Probably because although Oticon uses Bluetooth LE, there is either a proprietary connection or streaming protocol built in to the HAs.
As for AudioRelay and the similar SoundWire, they both work, but there is significant lag. Annoying if you are watching anyone speak/a movie, although they would be fine for just listening to computer audio.
You mean like MFi and ASHA? Yes, they are both proprietary.

I can do what OP is asking, with my ReSound LiNX Quattro aids, on my Windows desktop PC, using a ReSound TV Streamer 2. I connect the TV Streamer to the desktop PC with a digital optical cable; my PC has an optical audio out port; not all PCs have this port, so you have to check if this can be done on yours. The optical audio out port on the PC has to be configured in Windows’ sound settings. You also have to be sure to pick a TV streamer that is compatible with your model of hearing aids. Once you know the right streamer for your aids, you can often find them on eBay for much less money than audiologists charge. Then I use the ReSound Smart 3D app on my smartphone to switch the aids to that TV streamer, and the sound goes directly to my hearing aids using the streamer’s Bluetooth rather than the PC’s.
HOWEVER I don’t consider the sound quality good enough for music playback; your mileage may vary depending how your aids are set. I use this setup not for music but for yoga videos on YouTube; doing these I often can’t see the computer monitor screen, so I need the sound in my ear.
If I want to listen to music being played on the PC, I get better results with good mini speakers facing me, or headphones, with the ReSound app set to music playback, or with AirPods that have been set to my audiogram.
How does music sound quality differ for you using the ReSound TV streamer vs. mobile phone playback (assuming you might also be using the latter) with your Linx Quattro?
awful on my Android phone, Google use a 30 year old codec and TV streamer is much better
mike, as far as I know, and I’m sure someone will offer a correction if this is not accurate, the ReSound TV Streamer 2 uses Bluetooth to send audio directly to the hearing aids but cannot use Bluetooth to connect to an iPhone or other transmitting device for sound playback.
I believe the audio coming out of the device (PC in this case, or AV receiver, Blu-Ray player, etc.) has to be connected to the audio input of the ReSound TV Streamer 2 with a digital audio cable, which today’s smartphones can’t do. (Maybe there’s a way to rig it with an adapter coming out of the charger port, as you can for hardwired mini headphones/earbuds; I don’t know.)
I can use a digital optical cable from my PC to make this connection. There’s also a coaxial digital cable input on the ReSound TV Streamer 2. The original ReSound TV Streamer (1), which no longer connects to newer ReSound aids like the Quattros, could use analog RCA L-R audio cables and maybe an analog stereo mini cable as well to make the audio connection between sending device and receiving streamer, but TV Streamer 2 needs a digital cable AFAIK.
The ReSound TV Streamer 2 sounds great to me with spoken dialogue on TV shows and computer audio; it’s a big help. But for music playback, if I want to connect via Bluetooth to a smartphone, as I said, I’d use not the TV Streamer 2 but Apple AirPods Pro 2 earbuds or other good-quality Bluetooth earbuds (oh, and without my aids in my ears) or with Bluetooth headphones with aids in… with the playback volume set relatively SOFTLY to preserve what little hearing I have left! Those all sound quite good with music played on my iPhone.
One reason music playback doesn’t sound so great with TV Streamer 2 is that if you tell the aids to use the sound from the TV Streamer, you can’t also set the Music program in the Smart 3D app; it’s one or the other. Music doesn’t sound as good to me without the Music program set, because then I’m getting hearing aid settings optimized for spoken voice.
I was surprised about this so I looked.
According to page 8 here
https://www.resound.com/-/media/resound/resound-us/downloads/user-guides/400248011-ug-tvstreamer2.ashx
it can take digital coax, toslink and 3.5mm analog.

OK, so TV Streamer 2 can use an analog mini cable, which you can connect directly to the headphone port of older smartphones or get an adapter to connect to charging port of newer smartphones that don’t have a headphone port.
That could work to send music from an iPhone to TV Streamer 2, however, for me, I’d expect to still be getting sound customized for spoken voice through the TV streamer which is not ideal for music playback. It might be possible to fiddle with equalization on the iPhone to make it sound better with music, maybe using a 3rd party app.
What I do with current iOS and AirPods Pro 2 is customize the playback through the AirPods to approximate my audiogram; one reason I don’t wear hearing aids when using AirPods. Someone with less significant losses might hear music better than I do with ReSound’s All-Around settings.
Also just to be clear, anyone contemplating trying this needs to keep in mind that only compatible ReSound hearing aids can receive a Bluetooth audio signal from ReSound’s TV Streamer 2. A buyer has to check theirr aids against ReSound’s list of supported devices; only certain ReSound aids will work. Many other makes of aids that support Bluetooth have their own TV streamers, and some others may work with a Bluetooth signal from a smartphone or PC, I dunno.
I’m using the ReSound ‘Multi-Mic’ to get sound from my laptop to my Jabras.
The Multi-Mic connects via a thin cable with 2 male 3.5 mm connectors. BT or BTLE gets the signal from the Multi-Mic to the aids. The Jabras are new, and I’ve used the Multi-Mic only twice, but the 90 minute Zoom meeting was clearer by far than the sound from a BT speaker into the normal mics on aids, and the Multi-Mic is a lot less cumbersome than the TV Streamer 2.
The Multi-Mic isn’t cheap ($250?), but it’s a lot cheaper than writing the necessary driver.
