JNSA Replacement for WF 1000XM4 1000XM5 C700n Linkbuds S Memory Foam Ear Tips Noise Canceling Foam Eartips Ear Plug Ear Tip M Size 3 Pairs, [Fit in 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.

Sony's tips are hard and unforgiving, and I always noticed I am wearing ear buds (which is not cool). JNSA sizes are true as far as I can tell (I used small Sony and ordered small JNSA). The JNSA is much more like the tips on my Shure SE215 earbuds with similar noise dampening to Sony's (e.g., I cannot hear myself typing even with ANC off). As soon as I picked them up, I could tell they were much more comfortable, squishy, and forgiving. They are very comfortable and after wearing them for a while I forget that I'm wearing earbuds (as one should)!

Best foam tips for Sony WF-1000XM5, better than original Sony. Great fit, seals tight for excellent noise canceling, very comfortable. The white tips make the black buds easier to see.

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.
