Didn't realize the 65t were already on BT 5.0. Dunno how they improved battery life so much on 75t. Although at the ~$200 price point I'd rather spend a little more and get active noise cancellation. The problem with the 2nd gen Sony and Bose earbuds is they are both much bulkier than I'd like. I hate the protruding out of your ears look that makes it look like you're in 2005 wearing BT headsets in both ears.
