or, just rubber rings, like thisRegarding the fit issue with Edimun and Red De'mun, the solution that @golov17
and I use works very well with most earbuds where the fit is not great because the earbuds are a bit small.. Get a Monk+ with ex pack. You cannot have too many Monk+ by the way. Take a pair of the rubber rings with fins and carefully cut off the fins. Put them over the Edimun & Red De'mun and then put foams over. Voila!
