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)

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.

They work and are comfortable.But if your looking to get the same things that came originally, this is not that

Since using foam ear tips for the first time, I exclusively use them for all of my earbuds.I bought a pair of Sony WF-C500 earbuds in 2022, and immediately tried a "higher end" brand of ear tips with them. I sleep with one earbud in my right ear for 6-8 hours every day, and every pair of those "higher end" tips wore out within weeks. I switched to these JNSA brand foam tips, and they last me about 2-3 months depending on the climate in my bedroom. No matter the brand, foam ear tips are always affected by heat and sweat. The foam is attached to a small silicone ring which keeps the tip snug against the earbud - heat and sweat wears away the glue that keeps those two parts attached.For the price, these can't be beaten. I'll continue to use these for the foreseeable future.

The tips are even better than Comply and Sony- because the product is a hybrid of the two, imo.Comply-style, super soft compliant foam vs. Sony's slightly harder material with the 'eraser-cap' feel. The Sony shape is better than the standard Comply tip feel as it the front end goes a bit deeper in the canal and therefore a better and softer seal. It's less pointed of a tip.This is also substantially cheaper than both.

These are very comfortable and really seals excellent.Thank you

I bought and got the size M tips, but comparing them to the original M that came with the XM4 it turned out that they are smaller that the original ones. So, now they are useless for me and cannot return them.

Good product

The sound isolation on these is better than the stock or any other replacements I've found. Operating heavy equipment all day and I notice they are quieter. They block out some of the sounds that Active cancelation can't, allowing me to keep the volume a little quieter and I notice increased battery life due to that fact. They DO change the sound signature a little bit, kind of cut out some mids and highs because there is a little more foam off the end than the stock ones. But they go deeper in your ear making them block out more. Def recommend making a custom EQ for these, you can make them sound normal again. If you start to sweat though, due to them having a slight cone shape, they will eventually work their way out of your ear canal. So not recommended for strenuous excersize.
