Hello again head-fi'ers.
I want to make some statistics about the percentage of improvement between a universal and a custom.
Obviously, with so many iem's, some generalizations are need.
I ask to the head-fi'ers with a high class universal and a high class custom, to say what percentage of improvement is due to the better isolation and comfort.
My intentions are to calc the average, mode, range, and p-value of the results of this poll, and cross with the results of the thread "Improvement statistics universal to customs Part I"
I hope this will make the opinions about the improvement more objective and thus helpfull to thoose that don't are sure about jumping soo high.
Thank you very much.
