picked up a pair on ebay for roughly $60 less than in the shop here in UK.

Got them today. I love them! Sound is absolutely fantastic. I still like my koss but with the Shure I can get spare foam or plastic tips.

Anyway - here comes the question.

I am currently using the flexi tip size small. It feels like the headphones keep sliding out my ears all the time, and I don't get the full range of the sound. Am I using the wrong size tip?

Other than that - I can hear absolutely nothing of what goes on around me. It's quite weird to be this isolated from the rest of the world.
