Very soft plugs made of polyurethane foam that gently adapt to the anatomical shape of the ear canal. The closed surface prevents the accumulation of dirt and the ingress of foreign bodies. The patented X-Grip technology facilitates the quick and correct insertion and removal of the earplugs and reduces expansion pressure, ensuring high wearing comfort even during longer use. Well suited for medium and large ear canals. SNR = 37 dB (H = 36 dB, M = 34 dB, L = 34 dB).
