I predict the gnashing of the teeth will be start soon...
Guys, this thing has one year Apple warranty. It is a speaker, so anywhere in the EU and the future previous EU countries, it is covered by consumer protection laws which say it must last for a reasonable amount of time. Typically two years, but for speakers I would argue that a "reasonable amount of time" is longer than two years. So nobody in the USA is paying for the next year, nobody in the UK is paying for two years.
Solution: Be careful when you water your house plants, and don't water the HomePod as well. And I must say, I have never heard of anyone repairing speakers. I actually never had any speakers break. The first pair that I bought lasted forever, and I replaced them because I could afford better ones, which then lasted forever (forever meaning more than 25 years).
Speakers just don't break. Unless you break them. And if you think the amount that Apple charges is too much, then surely someone will repair them for less money if they ever need repairing.
