Only after I had the size M peeled on one side, I realized that it is only possible with a lot of tact, any plan to pull a new earplugs - I did it then also failed Size L top draw and only with great effort again the previous back But with size M. The size of M is also sufficient completely to me. I use my iPod for listening to music. If the work now far, I am delighted and completely satisfied.
