After reading about these foam buds, I couldn't wait to try them out. However, I've had terrible issues with their durability; they disintegrate after less than 2 months of use. It's a good thing this includes a pack of 6, because otherwise I'd have been left without functional earbuds very soon after getting replacements.
I take good care of my earphones. Always put them back into their pouch after use, and no rough handling. I will not be purchasing these again.
