When you buy their headphones, you can choose whether to sign up for a repair service, which comes in two flavours. You can choose unlimited repairs per year or unlimited repairs forever, where you pay a larger amount once and are guaranteed repair service for the rest of your life.

Hmmm, I don’t know. I’m disappointed that they don’t seem to be using common rechargeable AA or AAA batteries, but who knows, maybe they do. The “lifetime” repair service is more reasonable than I expected, at about a 1/3+ of the price of the headphones.
