JNSA Replacement Earbuds for WF 1000XM4 1000XM5 C700n Linkbuds S Noise Cancelling Memory Foam Earbuds Medium Size 3 Pairs [Fits Case] Black Medium Size (Foam4XM4B3PM)

Slightly to long they squish on the bottom of the case. But they work great

Foam earbud covers block noise better than silicone but must be replaced more often. These are less expensive than the OEM product, are just as comfortable, and last longer.

Good replacement for Sony earbuds, and definitely better price (you get 6 of these for about one OEM tip). Foam is a bit squishier, so sits in ear a bit tighter. Actual size almost identical so fits into case fine. A little hard to mount to the earbud - takes some wiggling to get it on right.

I've had the first pair wear after 4 months of daily use, longer than other mesh pairs I've tried. The wear was mainly with the silicone sleeve inside separating from the mesh, happened fully on one. It could probably be glued to keep it going longer, will try on the next. Otherwise the mesh kept most of its shape and there was no tearing. Make sure to buy dust/earwax screens as these have none. For the XM5 that's 4.5mm. I prefer it without built-in, as the screens can't be cleaned well. A minor fit issue I've had is one side coming loose with chewing motions. Could just need a large tip for that ear. I keep a loud box fan in my room and the seal on these is good as OEM. No noticeable changes to sound.

Got the mediums and so far they are good as the ones that originally come with the wf 1000xm4's also they do not get stuck in the case when you charge your earbuds they are the just the right size so you don't have to fish the tips out of the case which can be very annoying with bigger earbud tips
