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

They ear tips fit on the buds and fit in the case perfectly. Helps with noise canceling and sound quality.

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.

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.

I used these to replace the ear tips on my soundcore. They kept falling out at the gym. I used the large, squished them down a bit with my fingertips and pull the top of my ear diagonally back up into the ear to open the canal, slide them in and they stay put.

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.

They aren't long enough or big enough around to make a seal. Compare to actual foam earplugs,or even the silicone stock ones, they're extremely short.Seemed to work the first day. I was using power tools and it seemed fine. Got on the road and 0% noise canceling. I couldn't hardly hear the music at full volume. I'll attempt to reconfigure in the soundcore app, but if that fails, I'll return them and go back to silicone.

Improved sound quality, and comfortable.

These are a good upgrade from the silicone tips that came with my earbuds. They hold better in my ear and improve noise cancelation.

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.
