Update on this. I had stated the issue with BT volume was with earbuds but the volume in my car was perfectly fine.
Well, I'm happy to have discovered that my Jabra 10 Elite have a volume control on the right bud. I never turned it down or even used it, but I think when the feature was enabled through the last software update it was turned down somewhat low by default.
I also thought all it did was increase the BT volume slider on my phone but it actually increased the volume on the earbuds. I held until they emitted an audible sound signaling max volume and they are LOUD.
