Yes, I bought these first set Earbads for the Sony WF-1000 XM4 and they fitted well.

Yes, they fit on the xm5. However, you must note that the xm5 does not have a mesh cover over the earpieces. The original earplugs do, so the other earplugs should also have a wetted cover, otherwise you will have ear wax in them.

Unfortunately, I don't know the Galaxy Buds. They have an inner diameter of about 4.5 mm (when plugged in) and cover about 7 mm (length of the "axle for plugging in"). They are quite flexible - so if your Ear Buds have the same or a slightly larger diameter, they will pretty much fit.

Hi Ivansosanesper, no, these are not compatible. You can find the compatible swim earplugs below: Swim earplugs: size S PN 447605701 Swim earplugs: Size M PN 447608401 Swim earplugs: Size L PN 447608501 Swim earplug: Size LL PN 447608601 Sony Europe

Yes, the spare part also fits the Sony Linkbuds S.
