★Simply plug it into an available outlet to triple block vibration, noise, and dust! The MWA-EC magnetic wave absorbing outlet cap is easy to use; simply insert it into an empty outlet, and it triple blocks dust, vibration, and noise. First, the polypropylene insert pin, tuned to just the right hardness, suppresses the micro-vibrations of the electrode caused by the passage of current, improving muddiness of the sound. Second, the sendust alloy electromagnetic wave absorbing material, with its powerful noise absorption capabilities, powerfully absorbs the noise components emitted from the outlet, converting them into Joule heat and eliminating them. It also blocks dust and moisture from entering the electrode, preventing electrode deterioration and problems caused by poor contact. ■Product Features Simply plug it into an empty outlet to triple block dust, vibration, and noise. The polypropylene body, tuned to an appropriate hardness, suppresses the micro-vibrations of the electrodes that occur when current passes through. The 1mm thick MWA electromagnetic wave absorbing material (Sendust type) effectively absorbs and eliminates noise components emitted from the outlet. It prevents dust and moisture from getting into the electrodes, preventing problems caused by electrode deterioration and poor contact. Multiple uses can enhance the effect. Easy to remove by just pulling the handle. ■Product specifications Body: Polypropylene (PP) Electromagnetic wave absorbing material: Sendust-based electromagnetic wave absorbing sheet (1 mm thick) attached to the top surface of the main unit For use with 2-pole and 3-pole 100V outlets Quantity: 4 pieces
