I had the original version of these (Ray-Ban stories), and I had to return them three times because they kept dropping the Bluetooth connection. I more or less only wore them while running, so my best guess is moisture from my sweating got into them. Given that they were advertised heavily for sports stuff, that was disappointing. The return process was also complicated and annoying. Overall, I'd recommend against buying the first generation of these new glasses.
