i swap and change between std and scorpion end cans..the std is good for me.quiet and smooth on long runs,bit like me really  

 ,the scorpion is only just louder with a small rasp which i like,with baffle out its bad boy time,very loud  

 ,too loud for me  

 ...so was thinking of trimming the baffle down to get a happy medium  

 ....anyone done this before ?
