1_MEMBRANE: The construction of the patented ERKA. dual-membrane allows for an additional resonance chamber which optimizes the sound. 2_CHEST-PIECE: Highly polished and chromium-plated for a non-porous surface, the brass chest-piece ensures perfect surface hygiene. The non-chill ring ensures patient comfort and protects the membrane. 3_SPRING & TUBE: Through the separately integrated spring in the tube, there is no acoustic loss from the chest-piece to the ear. Two internal channels run parallel in the stethoscope tubing. This prevents the friction noises caused by two separate tubes. 4_EAR TIPS: The ergonomically designed, super soft ear tips create an excellent acoustic seal against external noise interference and maximize wearer comfort and fit. 5_BINURALS: The ergonomically shaped and individually adjustable binaural ensures optimum fit. The standard 15° inclined binaural can be individually adapted to the ear canal characteristics of the user.
