Thanks for your post. My right ear bud hasn't worked for the last 6 months and mine didn't come with a cleaning brush or replacement mesh. I ended up using a very sharp fine tip knife and lifted up the mesh and completely removed it. I think there must have been glue that got into the mesh and blocked out most of the sound. After removing the mesh and re-inserting the tips and wings, I now have loud volume again. Though I will need to clean frequently so that dust and ear wax don't go all the way into the ear bud now that the mesh won't screen and prevent build up.
