Here is an earbuds public service announcement : remember to clean them with alcohol on a regular basis. (inner ear pimples can be painful) Worth buying a little cleaning kit with small cleaning sticks and some pipe-clean like brushes. Also watch out if there is a fabric or glued cover on the sound hole: alcohol will probably dissolve the glue (these aren't really designed to last long or be cleaned) Its usually fine to just let the rubber hold it, or use a tiny amount of RTV silicon to glue it back in place.
