Memory Foam Tips for Sony WF-1000XM4, Anti-Slip Replacement Ear Tips for Sony True Wireless Earphones，Fit in The Charging Case, Perfect Noise Cancellation, 3 Pairs (Medium, Black)

Do not buy these if you have issues getting the stock Large tips to seal. These are worse. I could get a seal on the right with the stock but not once with these. They are slightly larger than a medium stock tip though.I can't rate the quality, comfort or noise canceling because I could not seal.

I inadvertently destroyed the foam tips that that came with my earbuds, by cleaning them with an alcohol anti bacterial wipe - they just disintegrated ! Purchased these as a replacement and they fit perfectly.

The media could not be loaded.  Good

Don’t be fooled by good reviews. These are very poor quality and don’t work well with Sony ear buds. Leak sound and just over priced and poor quality. Been ripped off yet again by Amazon!!!

Excellent quality

These size L are not the same size as the large original so the seal is insufficient.
