I tried these ( https://smile.amazon.com/gp/product/B083...UTF8&psc=1 )and they worked great for a while and then stopped working. I exchanged them for a brand new pair and same issues.

I tried these: https://smile.amazon.com/gp/product/B088...UTF8&psc=1 and had the same issue.

This is the USB adapter I'm using: https://smile.amazon.com/gp/product/B07R...UTF8&psc=1

I'm not sure what broke. I had used the first set for months w/o issue. I don't recall when (or why) I upgraded to the latest firmware so I'm not sure if that is when it started or not. Any issues with this Firmware?

Hi Allen,

I suppose the USB adapter you use is the Yealink Bluetooth USB Dongle BT41.
Both headsets use the Bluetooth spec V5.0 but I can't find any info on Amazon if the headsets can also work with BT V4.1
I guess and it looks like, there is a misconfig in BT versions between dongle and headset(s).

BTW. Did you reset the phone to factory default after upgrading the firmware?

Best regards,

Please do not send unsolicited PM messages. I will not answer them.
