Symbio W

The new ear tips, known as "Symbio W" are created using memory foam and silicone in the manufacturing process. Foam fills the space between the stem and the outer ear tips, and silicone is used on the side that meets your inner ear. These ear tips combine the comfort of foam ear tips with the sound quality of silicone ear tips, making them the greatest option for music lovers and audiophiles who enjoy listening to music for extended periods of time while on the road or during nap time. These ear tips fit most IEM nozzles on the market with a stem diameter from 4.5mm up to 6mm. The bore diameter of Symbio W is 4.5mm and these ear tips come in sizes small, medium and large.
