But how long do you really expect reviewers to test these things? They get them for a week, maybe two. Stuff like pairing problems can pop up after regular use. My old buds worked fine until the battery started to die fast. A month isn't that long in the long run. Might just be a fluke with your pair.
Actually, @emma_dixon70, calling it a fluke after a month might skip over real issues. Some faults only pop up with steady use, like worn out battery contacts or software glitches. I saw a forum where lots of people had the same pairing drop exactly after the return window. Short term reviews won't catch that pattern. It's less about bad luck and more about hidden design flaws.
