Westone Audio True-Fit Foam Replacement Eartips - 5 Pair Pack, 12.6mm Diameter X 11mm Length

As Westone's version provide deeper seal, and it blocks surrounding / ambient noise much more efficient.

These work well as replacement

I'll start off by saying that these do not fit my earbuds. I knew it was a gamble when I ordered them but figured I'd give it a try. My earbuds are much bigger then the green sleeves that are inserted into these. Tried to pry it on over but that didn't work. I used a pencil and forced out the green sleeves. They then fit perfectly onto my earbuds with the exception of falling off easily during removal from my ear. I then used a little superglue on each one and haven't had any problems since. I use them sitting around, working out, running or whatever and am still on the first set after 7 months. They are still comfortable. I compress them then insert into my ear and let expand. They also help block out a lot of the ambient noise. When they stop expanding after compression or being comfortable I'll tear them off, scrape off the glue, and glue on another pair. Still have 4 to go.

Passt perfekt auch für IEMs der ER Serie (2,5mm Durchmesser am Tube). Passt sich perfekt dem Gehörgang an und ich muss die InEars nicht mehr so tief rein stopfen um perfekte Abdichtung zu bekommen. Es kommen minimal mehr Aussen Geräusche durch als bei den original Tips mit 3Dichtlippen...ist für mich persönlich aber sehr angenehm. Immer ne Empfehlung wert!

These fit the buds, but are quite a bit bigger than expected
