Anyone that has experience with in-ears, also expensive ones, would not blink before buying quality third party foam tips. They are a gazillion times better than anything that comes with the earphones (except many are now shipping Comply tips with their earphones). So buying third party cushions and expecting an improvement is not that far fetched.
Of course, tips are different since they can fit a large variety of earphones, while cushions has to be made specifically for the earphones, so it's hard to get anything quality from anyone but the original manufacturer.
