Keep the headphones. Change the part.
A worn part need not mean the end of a familiar pair of headphones. AIAIAI builds the TMA-2 around components that can be changed.

In practice. AIAIAI sells TMA-2 configurations, separate parts and repair kits, with official repair guidance.
What to keep in view
Compatibility differs between components and generations. Modularity alone does not establish a measured environmental saving or guarantee indefinite parts availability.
Your next pair might be this pair
The Danish audio company offers ready-made headphones and a build-your-own system. Individual components let people adjust a setup instead of starting again with a complete product.
That matters when the object is something you use every day: a fit you know, a cable you prefer, a sound you have become used to. Modularity makes keeping some of that familiarity possible.
Repair needs more than a promise
The repair programme includes kits for compatible speaker units and instructions for the work. The practical test is whether the right part remains available and whether you can carry out the repair.
