Option 2: Don't buy AppleCare+ for Headphones. Out-of-warranty battery repairs are still cheaper than buying a new pair of AirPods Pro.
After the one-year warranty expires and without AppleCare+ for Headphones, it'll cost $49 to replace the battery in each AirPods Pro, and an extra $49 to replace the battery in the AirPods Pro charging case.
That's about $150 to essentially get a new set of $250 AirPods Pro, including a new charging case.
This option lets you replace your AirPods Pro batteries whenever they wear out without spending money on AppleCare+ for Headphones, which you're not guaranteed to make full use of.
Neither options is perfect.
Do you buy AppleCare+ for Headphones and hope your AirPods Pro battery wears out within the two years? Or do you just "service" your AirPods Pro whenever their batteries wear out and get a new replacement pair for $100 off the price?
That's up to you.
