Memory Foam Tips for Sony WF-1000XM4 / WF-1000XM3, Anti-Slip Replacement Ear Tips for Sony True Wireless Earphones，Fit in The Charging Case, Perfect Noise Cancellation, 3 Pairs (Medium, Gray)

Excellent product. Original Sony product has one set of small earbuds...so I was skeptical when I bought this and it turns out this product is excellent. It even exceeds Sony's original earbuds in durability. Worth it and a good fit for XM4s.

Great replacement, fits my ears nicely. Sounds as good as ever!

Update: I dropped my review from 5 to 4 stars. I bought these in a 6-pack about 8 months ago now and im down to the last set. With constant use the sticky tack holding the rubber to the earbud tips eventually breaks apart and my tips separate. I still think they're great tips but im buying more after 8 months. I bought these to replace the ones that came with my headphones because they were already cracking and falling apart. I went with the medium tips to replace medium tips and, like some reviews mentioned, they’re a bit smaller than the OEM tips. I personally like the smaller size much more and the new material is way more comfortable. Especially since I’m using them around 5-6 hours a day at work for noise cancelling.

These are not the same quality as the originals. Not the same shape nor thickness. Not even what's pictured on the package. Doesn't block noise nearly as well. They do fit, but the foam is too thin to be as effective.

The are slightly shorter in length compared to the original foam tips that come with the earbuds, but they work just as good for noise cancellation and overall fit in the ear. I would definitely buy again.

Not too long after use they fall apart so easily and will ball up in the ear, not form fitting. Ultimately very uncomfortable. Disappointed

Just like the title states... These tips are far better than the original tips that come with the Sony WF-1000XM4's. I managed to destroy the original set (both small and medium sizes) in right about a month before ordering these. Not only are they much more comfortable, they also manage to capture less ear gunk while still molding nicely to the ear canal. I have been using these tips for the last two months and have yet to replace them. These are a must have and I will be buying these tips again in the future.

The set of medium tips that came with the headphones lasted about a year before I bought these replacements. I've had them less than a month and all 3 sets of replacement tips have fallen apart. They work well for a week or two but then the outer foam separates from the inner ring and they're useless.
