I’ve been using the Philips 9040 for a week and a half now with my Google Pixel 6a.
I find the streaming to be acceptable, but I’m no audiophile. Unfortunately, the road traffic noise overpowers the volume of the hearing aid when I’m on my daily walk.
I can tell that the sound from the hearing aids with using headphones is not as good as without the hearing aids and using headphones. So I would expect streaming not to be any better. But I would say the sound is acceptable. Note I don’t have a music program yet, so that may completely change things.
The only issue I’ve had was pairing the phone to the hearing aids initially. However, one paired they seemed have remained paired. Hopefully they stay that way.
