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.

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.

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!

Received silicone ear tips, not foam.

The eartips themselves are fine, quality is decent for the price. The problem is that there are fewer size options than the ones that come with the earbuds, and the Large in these is smaller than the largest sizes included. So, in my case anyway, I'm getting a better seal using the tips included with the earbuds than I can with these foam tips. Obviously this will vary for by user.

Not the most comfortable and slip out easily

Not impressed, Awkard to fit, uncomfortable to use

Sehr gut für meine Ohren,die Originale mussten die ganze Zeit korrigiert werden, die neue kleinste Größe, wenn man das erste Mal einfügt, scheint groß zu sein, aber nach 5 Minuten fühle ich mich nicht mehr, sehr bequem und fest, sehr zufrieden.
