I've had this pair of Sennheiser HD 495 headphones for years sitting in a drawer. I think it's time to give them a new lease of life.
Step 1: MATERIALS
A4 sheet of foam 5 mm thick (I used some old off cuts you can use thicker pieces)
Step 2: CAREFULLY PULL APART
Pinch the earphone cloth piece and carefully pull apart.
(Please note: I managed to tear the cloth away from the other earphone but I was able to superglue it back together).
Step 3: BRUSH / HOOVER
Using a small brush, brush away any loose bits from the headset then using your fingers dig out any of the loose bits from the cloth and hoover.
Step 4: WASH / DRY
Fill a plastic container with fabric conditioner and water and clean the cloth piece earphone and dry with paper towels.
Step 5: CUT FOAM
Take one of the fabric earphone pieces and use as a template to draw around onto the A4 sheet of foam then cut out with the scissors.
Step 6: INSERT FOAM
Once the fabric earphone piece is dry insert the cut foam piece and click back into position on the headphone headset. Repeat this process for the second earphone piece.
Step 7: CLEAN / DRY
Using the fabric conditioner dab the fabric underside of the headset and dab again with paper towels to dry.
Step 8: FINAL CLEAN
Finally clean the headphones with cleaning wipes.
