Premium Range 6 Replacement Earbuds Tips Buds For Sennheiser CX300 / CX400 / CX500, Sony EX71 / EX81 , Phillips, Creative, Sharp, Panasonic, Skullcandy, Sony Ericsson Headsets, Denon, Griffin, ezGears, JBL 100% FITS (Small, Medium & Large BLACK)

They come in different sizes and only 1 size fit my earphones. They're good but be wary of your size.

these are clearly not made for the sennheiser cx-300. i got three different sizes, none of which fit the actual stalk that the earbuds sit on. neither do any of them actually match the size of the sennheiser earbuds so they just fall out of my ear every couple of seconds. they also don't have the little strip of rubber across the end to guard from wax etc. very poor product. cheaply made. nowhere near the right size. very dissapointing. it's rather frustrating that i'm going to have to buy a brand new pair of £50 headphones just because i lost one measly earbud and the only replacement ones availabe are cheap, poorly made knock-offs. pathetic

They do the job.

These are sort of okay. They don't fit the headphones perfectly as has been discussed elsewhere but once you get them on they are pretty tight. Work well enough.

I bought these for my SkullCandy earphones as I'd last the original ones . But none of these fitted :(

These buds are a fine replacement for my damaged cx300 'phones. not much else to say, really!
