C40 Foam Tips are specially designed to provide maximum comfort. Tthese tips have a unique spherical shape to reduce the amount of pressure on your ear canal. That means no more interruptions during your listening sessions due to ear pain. Whether you’re enjoying music at home, work or on the road, the C40 offers a host of fantastic features to enhance your listening experience. The first time you experience a C40 Foam Tip, you discover there’s something amazing going on. It feels better. Fits better. Sounds better. And as it expands to perfectly fit your ear canal, you realize one thing: There is no going back. Rooted in our unique viscoelastic memory foam technology, our tips conform to the shape of the ear canal at body temperature for a dynamic custom fit. Your ear canal shape and size change with movement and temperature. And now your earplugs change with you. This true fit seals in low frequency energy. It won’t leak bass, for a richer sound. Materials are also engineered to provide optimal friction coefficient, so tips stay put. Optional built-in filters protect earphones from wax and debris or sweat. Acoustically transparent, with less than 2dB transmission loss. And flexible core in multiple sizes assures we have tips to fit most earphones.
