Moving the discussion about streamers from the Costco CS8 page, as previously requested by management, to avoid thread hijacking,
I’m not clear on what you are trying to stream from or stream to, but if you find it relevant I can tell you that:
for direct mono streaming into my HAs (KS5s) I now plug an audio cord from the sound source into the audio-in port of my spare Resound Unite Microphone Clip (when I am not listening to Karen whose voice is picked up from my other Resound Unite Microphone Clip.)
for stereo streaming of movies or music, I recently purchased an Avantree Low Latency aptX Bluetooth Transmitter which sends high quality lip-sync’d audio wirelessly into my Avantree Clipper Pro plugged into my cushioned headphones worn over my HAs. Experimenting further, I have found that the Clipper Pro can also be plugged into the audio-in port of my spare Resound Unite Microphone Clip so that it streams right into my hearing aids, but of course I am not going to get full, rich sync’d sound that way.
Is that what you had in mind?
