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.

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.

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.

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
