I just replaced my ear pads last week. Very straightforward. There's basically tiny snap on clips around the edge and you just pop them off. Put the new pads in using the same clips.
I bought these off Amazon: https://www.amazon.com/dp/B07TZJ1CMC?ref=ppx\_yo2\_dt\_b\_product\_details&th=1
Yep. Just buy new ones. I bought these
These replacement pads worked quite well for me.

This is the last pair I got. It's really good actually. Can barely tell any difference. https://www.amazon.de/dp/B07TZJ1CMC/ref=cm_sw_r_apan_glt_i_27V6K0NCA6FYFT1MR9FC
1 year into daily use of these $20 replacement pads and would buy again in a heartbeat.
awesome! thanks mate! I just went on amazon and found these. Do you think they would work on the 1S? The bose are hand me down therefore I do not want to ask my gracious gifter because that would be rude of me. And I never had such great earphones so I know nothing about them! Thanks for your help!
