Ok, I’m not sure that this was all that was reset for me to solve the Bluetooth static problem but this is what my audiologist says:
> The most significant change was definitely increasing the NoiseBlock on all streaming programs as well as switching on/increasing Soft noise reduction on the streaming programs.
> And for others to hear you better we changed from Adaptive Bandwidth to Fixed Bandwidth for the Bluetooth streaming on phone.
I also have my HA locked to Auto only as without the app I find it difficult to manage program changes with the buttons.
I also realised that the CROS takes up one of the active Bluetooth connections available, so I have to manually swap between audio streams.
I think the CROS switches off for phone calls which means only one microphone is available to pick up my voice, which explains why I sound faint to the person on the other end of the call.
Finally, now I work from home and want to connect PC audio to my HA for Zoom/MS Teams meetings, I found I got a lot of crackling on the steamed audio. This was also affecting phone calls. I think I have solved it.
I have a dual band WiFi router with 2.4GHz and 5GHz bands. I haven’t used the 5GHz band before. I found switching as many home wireless devices (2 Smart TVs, sound system, 3 PCs, 3 mobile phones, tablets) to 5GHz WiFi as possible eliminated the crackling on my HA! So, seems like interference in my small home on same 2.4GHz frequency used by HA was a factor. Unless it’s a huge coincidence….
I hope some of this helps.
I am a bit sad that so many of the sophisticated Phonak features are unable when using a CROS. Jury still out on whether I will keep them or start over with another brand.
