Hi,
I got a set of Sennheiser CX 300 earphone, and I have lost my ear buds. I'm sure that mine was the medium size.
And the only web sites I can find that have them are selling them in a 10 pack. I understand that they do also fit Sony and others in ear head phone.
So the option is to ask if any of you lost want to share them, or have a set laying around that you are not using. Or do any of you know where I can buy just one set of the buds.
