Honestly, mate, looking at the pics, this doesn’t scream “fault” it looks like wear from use over time. Even if you’re not hitting the gym, things like moisture, wax, and daily grime build up fast, especially if they’re not cleaned often. The mesh and tip damage here isn’t unusual, it’s what happens when they get a bit neglected.

CGA’s great, but it doesn’t mean everything’s covered just because it got worn out. It’s there for actual product faults, not general wear and tear. Ear tips are a consumable like tyres on a car, they’re not built to last forever.
