What does the 15 mean on the temple shocks ? Thanks in advance

As @Nucchem mentioned they cone in different sizes which denote thickness. lower number= thinner. if they are loose in your head you need a thicker t-shock.

T-shock came in different sizes to adjust fit;
15, 25,50 and 75.
Higher the number, tighter the fit.

You can mix and match for the best fit - I use a 15 one side and 25 in the other on all my x-metals...
