I’m still on a pair of 1st gens. Been round the world with one of them 8 years ago and it’s still going, so happy to have had it accompanying me, and now with two, just wow.
Yes stereo pairing was a pain with one or both cutting out occasionally, so also interested to hear if it’s any better on the 3rd gen, however I do sometimes use the 3.5mm port that only exists on the 1st gen for connecting to my portable projector. I literally have an amazing stereo cinema in my luggage with no lip-sync issues. (I believe two in stereo introduces even more Bluetooth latency than just one, often beyond any audio delay setting even if your projector does have that ability which mine does)
