n=1, but I experienced similar Bluetooth issues with the iPhone XS Max, which would constantly lose connection when compared to the iPhone 7 I’d had previously. The problems disappeared when I tried the iPhone 11 Pro, so I concluded the problem was with the specific XS Max I had, and got it replaced. I also noticed pairing issues in the defective Max with a first-generation Apple Watch. It was working better with the replacement Max, but connected best with the 7 or 11 Pro, all the same. So Bluetooth definitely seems to vary in quality from handset release to handset release, and more than I’d expected. Similarly, I’ve had bad luck with some computers but good luck with others, I’ve yet to pin down why. Generally the best Bluetooth connectivity range (for me, at least) is on the iPad Pro and the worst seems to be tied between watches and other small devices, or Windows computers because the apps aren’t optimized for Bluetooth AAC streaming as much, I think. With AAC streaming, I suspect the song I’m listening to has a larger cache on the headphone to make up for listening range issues, but I could be wrong there...
