What's the standard warranty on the homepods? Sounds like it may be worth it to add applecare?
If you buy the HomePod with most major credit cards, you probably already have extended warranty coverage. Typically this is double the mfr warranty up to a year, so you are probably covered for two years total. A lot of people don't seem to be aware of this.
Double check your credit card benefits to be certain. But I've had Visa, Mastercard, AMEX, and Discover, all of which had it.
