JNSA Compatible with Soundcore Space A40 Foam Ear Tips, Noise Canceling Memory Foam Ear Tip Replacement for Soundcore by Anker Space A40, S/M/L 3 Size 3 Pairs,Black (2143PB)

Ears are as different as fingerprints, so these might not work for everyone. That said, they're foamy enough to get a good seal and block outside sound and they stay put without requiring constant adjustment. Other reviews suggest that they don't last long and typically only one size fits so, in addition to the pack containing 3 different sizes, I wish they were also sold as three pair of a single size. But the bottom line is they do the job much better than those that came with the ear buds.

I use my A40's pretty much continously every day from the moment I leave my house till after work and these are the only foam tips I've found to stay on the bud itself and in my ear without issue. Ive bought over half a dozen of these boxes only due to wear and tear and the lack of multiples of the same size. 5/5 for Soundcore A40's this is your Foam Tip answer

Pros: 1) Very easy to install - the tips slide right onto earbuds with no problem 2) Comfortable - don't even notice the earbuds are in your ears with these tips 3) Stay in place - these tips keep earbuds in your ears very well. With these tips, you can wear your earbuds and be active and they stay in your ears. 4) Come in a small container that has a lid that latches. This is nice because you can keep the other size tips in this container and not lose them. Cons: 1) Noise cancellation is not great. They do cancel some noise, but if you are looking for complete cancellation these tips will not work for that purpose. Summary: As you can see the pros definitely outweigh the cons with this product. If you are looking for strictly noise cancellation these tips are not the solution. If you are looking for a comfortable earbud tip that keeps earbuds in your ears then I would definitely recommend this product.

Anker's original silicone tips slip out of my ear all the time. It's annoying. Just tried my new foam tips. I can vigorously shake my head -- and they stay in place. This fixes my #1 problem with the Soundcore A40 earbuds: great sound, but easily slip. This was worth every penny. Thank you!

I’m enjoying my new ear buds, they perform exactly as advertised. They fit nice in my ears and the sound quality is awesome, Easy on your ear and they’re compatible for music, audiobooks and phone calls.

I've wished for foam tips on my earbuds for a LONG time, so I was very happy to order these. Unfortunately, the Soundcore Space A40 charging case is pretty tight - it requires the foam tips to be a meagre 6.5mm deep and this fundamentally limits their ability to work properly. Maybe I have weird ears - maybe it will work better for others - but for me, they were less secure than the silicone tips and didn't really improve the noise cancelling.

I got these hoping they fit on my Anker Soundcore A20s, and they do! Way more comfortable and noise cancelling than the stock silicone tips, and they stay in place better all night. Deepest sleep I've gotten in a long time.

These did exactly what I wanted them to do. I love my space A40s, but they were constantly slipping out of my ears. Ive put these on and thats no longer an issue, my earbuds are staying in and sound great, with the added noise canceling of the foam. The only thing I would suggest for improvement, is addition listing, one like this one with the three sizes, and for each size a listing that is 3 sets of that size. I can already see signs of use on the ear tips after just a week or 2, which is the nature of something porous being around wax and sweat and such, so the ability to easily buy replacements with out getting extras I wont use would be amazing.
