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.

The silicone ear tips that shipped with my Soundcore earbuds would not hold them in my ears. These are perfect-they never fall out now, and they are comfortable enough to wear for hours. They also improve the noise reduction feature of the earbuds.

Pros:1) Very easy to install - the tips slide right onto earbuds with no problem2) Comfortable - don't even notice the earbuds are in your ears with these tips3) 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!

Received silicone ear tips, not foam.

Not the most comfortable and slip out easily

These fit perfectly. Before I would have to hot glue foam tips to get them to stay on the ear bud. Now, unless your earbuds gets ripped out, the foam tips stay securely on!

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.
