BLLQMemory Foam Tips Compatible with Sony WF 1000XM4 Replacement Ear Tips,Perfect Noise Cancellation, Fit in Charging Case, 3 Pairs [Medium Size] Foam Tips Black M (Foam Tip XM4M)

Update: I've seen the other review that was posted for these and i wanted to clarify some things. The review said that the foam was thin, but in my experience there is more foam than the oem tips. Ive added a picture comparing the small oem foam tips (orange inside) to this set of foam tips (green inside). That being said, hes using the XM3 instead of the XM4; so his review should not even be considered because these arent listed to fit the xm3 ear buds. I dont have an issue with the xm4's falling out with these. Its been a couple days, they are still comfortable to wear and they dont have any tears in them as of yet. Ill update this when i get a tear in them to track how long it took.I stock shelves at a grocery store overnight, so I typically wear my earbuds for 6+ hours a day. For the money these get the job done. I've only worn them for one night but I can say happily that they were comfortable to have in the entire night. I can't speak for the long term durability but if they end up lasting as long as the comply/oem foam tips than I'd say that's a win, considering if I recall you can buy a single pair of foam tips from Sony for the price of these 3 pairs, and comply tips typically cost 2X to 3X more than these, and I find that the comply tips only last about a week or two per pair, since I tend to take them out a lot to talk to other employees. I don't mind if I have to buy a pack of these once a month especially since the comply tips I had for my last pair of headphones were 20 bucks for 3 pairs. Something else to note is that they come in a little plastic case, useful for keeping them all together. Sound quality also doesn't seem to be affected at all either (from the oem foam tips). Overall, I'm pretty satisfied.

I like that they fit. I like the price, actually closer to reality than the insanely overpriced ($19+) sets.However, I don't like that the foam is nearly as thin as the oem silicone cups. Smash them and they stay smashed for a few minutes. Jury is out on whether or not they will keep the xm3's from falling out (like the oem cups) when I lean over.

A parte de ser de muy mala calidad me mandaron la talla que no era.Los de color beige son los originales.
