Sony Noise Isolation Earbud Tips EPNI1000 (L).
High sound insulation.
The earpieces are made from Sony's unique polyurethane foam. Soft and flexible, it improves adhesion to the wall of the ear canal, minimizing gaps in the area of contact with the surface. This improves sound isolation and removes more noise, especially in the high frequency range, for a more immersive listening experience.
A more stable fit
A combination of elastic and foam materials with a unique structure helps to increase the contact area between the earbud tips and surface of the inner ear, ensuring a more stable fit that makes them easy to wear, whatever the size and shape of your ears.
