ALXCD Eartips Compatible with Sony In-Ear Headset, S/M/L 6 Pairs Soft Silicone Ear Tips, Compatible with SONY In-Ear Headphones MDR-XB50AP WF-1000XM3 XBA-H1 WF-XB700 WF-SP800N, etc. 6 Pairs, SML White

These work ok but I was replacing a pair of foam tips. You receive 6 pair but only the large fit me so I’ve got 4 pair that do me no good. Will reorder foam tips. They stay in my ear better.

Very suitable replacement for the foam ear tips that come with sony wf-1000xm4.
