I’ve got a set of 6 year old $60 taotronics headphones that I just replaced the earpads on. Took 5 minutes and they use generic earpads available from AE or Amazon. The battery is soldered in, but is a generic lipo foil pouch accesible behind a screwed together earcup so I won’t need to find a specific form factor or break any glued together stuff to get at it.

I don’t see this product as more “repairable” than other products. I do see that it has a lot of modules that are designed to be thrown away and replaced easily without throwing away unaffected parts.

Repairable? Not in the strictest sense. I don’t see schematics and board layouts for repair people. Are all components 0805 or bigger so a blown capacitor can be easily replaced? No way to know, because they haven’t published how you would go about actually diagnosing and repairing failed components instead of tossing and replacing the module they are housed in.

Honestly, for the price you might as well just pick up a nice set from a company like Bose that has a service and repair department, and a demonstrated commitment to longevity and quality.
