Alpine Musicsafe Pro vs Etymotic ER20

I have been using Etymotic ER20 plugs occasionally for over a year. I decided on these after reading numerous positive revies on them. However, the plug starts to itch in my ears after an hour of use. Last week I decided to test a pair  of Alpine Musicsafe pro plugs during a club night. I had them for nearly six hours in use and didn't feel them itching at all. The attenuation was good and it was easier to have a conversation with the plugs than it would have been without and finally the best part...no ringin ears after the night out!
