Pair to BlueTooth Hearing aids?

I may be wrong but...

Here is a detailed answer in English you can post to that user (you can adjust small details for your exact hearing aid model and phone):

You can use Meta Ray‑Ban 2nd‑gen AI glasses together with Bluetooth hearing aids, but there are some important limitations in how the audio is routed.

First, the Ray‑Ban Meta glasses connect to your phone over Bluetooth and show up as a regular Bluetooth audio device (like headphones or a speaker). They provide open‑ear speakers in the temples for music, calls, and AI voice responses, and newer models also add AI features like Conversation Focus to enhance speech in noisy environments, but they are not medical‑grade hearing aids

Your Phonak (or other Bluetooth) hearing aids also connect to your phone as a Bluetooth audio device, usually through the iPhone’s Accessibility > Hearing Devices menu, which allows you to stream calls and media directly to the aids. The key limitation is that iOS normally routes audio to only one Bluetooth “endpoint” at a time (except for special cases like AirPods), so the phone will not simultaneously send audio to both the glasses and the hearing aids.

In practice, this means both devices can be paired to your phone at the same time, but you must choose where the audio goes for each situation. On iPhone, you do this from:

• Control Center → long‑press the audio tile → AirPlay icon → select either your hearing aids or the Ray‑Ban Meta glasses as the audio output; or
• Settings → Accessibility → Hearing Devices / Audio Routing to prefer “Hearing Devices” for calls and media if you want everything to go straight to your hearing aids

What you cannot do (today) is use the glasses purely as a remote microphone and have the iPhone “forward” that audio in real time into your hearing aids via Bluetooth. The phone treats each device as a separate audio endpoint, and there is no built‑in iOS feature that mixes the microphone from one Bluetooth device and sends it live into another Bluetooth device

So the realistic options are:

• Use only your hearing aids for audio (calls, music, etc.), with the Ray‑Ban Meta glasses connected for camera/AI/visual features but not as the active audio output.
• Use only the glasses as the active audio output when you want open‑ear audio and AI voice features, knowing that sound will come from the glasses, not from your hearing aids.
• Frequently switch the audio output in the iPhone’s audio menu depending on whether you prefer the hearing aids or the glasses in that moment

If you rely heavily on your hearing aids for speech understanding, the best setup is usually: route all calls and media to the hearing aids in iOS settings, keep the Meta glasses paired for camera and AI features, and only switch the audio to the glasses when you explicitly want to listen through the glasses’ speakers.

Thank you for your reply. My Meta Glasses are gen 1

my hearing aids are Kirkland (Costco) gen 10

Phonak is a service. Helps direct hearing aids.

I think I can work with your ideas, though I am not proficient with the tech. I will try and get back to you.
