High sound insulation
- The earbud tips are made using a unique polyurethane foam material developed by Sony. Soft and elastic, it improves adhesion to the wall of the ear canal, minimizing gaps in the surface contact area. This enhances sound insulation and cuts out 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 the surface of the inner ear, ensuring a more stable fit that makes them easy to wear, whatever the size and shape of your ears.
