Looking for a pair of good Gehörschützer'n (mainly for the shooting), I came across the 3M ear muffs X4A. Attractive design, not so expensive and adjustable in height and after I could test yesterday, 5 stars. The Geräschdämpfung is very good (to my mind, anyway) and the setting is long enough to still wear a cap underneath. Delivery was again very fast, I am satisfied! Mfg. from Three runners
