What is most bizarre is that they worked fine for months, then suddenly they don't.

I thought the headset went bad, so I exchanged it. I'm not sure what has changed.

Hi Allen,

Please make sure the phone, running f/w 66.85.0.5, isn't the cause of the intermittent one-way problem.
If possible, use the phone's handset instead of the headset to test it.

The phone works find on handset and speaker phone. Only on bluetooth do I have issues. I downgraded to 66.84.0.125 and same issue. I'm back at 66.85.0.5 now.

Hi Allen,

When you changed the headset, did you also changed the BT dongle?
Maybe the dongle have issues.

Again I did not find any word on Amazon saying the headset is backward compatible to BT v4.1... are you 100% sure the headset is fully backward compatible... did you read that?
