TENNMAK Memory Foam Eartips Earpad for Sony WF-1000XM4 Replacement Earbuds Tips & WF WI XBA Series WF-SP900 WF-XB700 WI-1000X, Fit Charging Case… (Large 6pcs)

Do not but these. I ordered large and the ones I got are tiny and extremely soft. They don't expand in your ear so they keep falling outAvoid

They are comfortable and fit well in my ears. Although the diameter is big enough, they are shorter than the Sony originals.
