KOSS Replacement Ear Pads for Porta Pro and Sporta Pro
Product Details
Replacement parts for KOSS on-ear cushions. Outer diameter: 48mm, Inner diameter: 32mm, Depth: 9mm.
Purchased around 2022. I used one set of cushions, but around 2025, my headphones broke, making the remaining two sets unusable.
The two sets (4 pieces) are still unopened, so I am listing them as Near Mint.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
