> If apple no longer sells the battery, it will be trivial to find a suitable replacement. As long as there is demand, there will be loads of shops able to replace the battery for you.

Its a niche product. You will bot find replacement batteries for it. Heck it is even hard to find replacement batteries for 10 year old MacBooks.

> The real question is: will people who buy $500 branded headphones really have their 5+ year old headphones repaired, or will they but the latest-and-greates shiny new thing?

That’s my whole point. These things are not build (and bought) to last anymore but to be consumed. You used to retain some value when buying into expensive headphones.

Not sure if you're trying spread FUD, but NewerTech (owned by OWC) batteries are readily available for older Macbooks/Pros. Just checked their site and they have replacements for the 2008 Macbook.
