I couldn't find any relevant source for changing the earpads for my favorite mini headphones AKG K 420 on the web. So I decided to give a short guide how I have done it. I have bought this non-genuine earpad replacement in Media Markt (Vienna) - PUNEX Ersatz Schaumkissen. The size (big) I estimated in the shop and it seems sufficient. 0. Motivation. For comparison - old and the replaced new one: 1. I took the old earpad off. You can see the gap around the earpad. I didn't want to dismantle it further. 2. Just with my bear hand I put a new earpad on the headphone. 3. But then it looked like this. The earpad didn't fit tightly. 4. So my trick was to use some sharp and very thin knife. I pressed carefully the edge of the earpad inside the gap all around the headphone. And that's that. Happy listening.
