Fanmusic Dunu S&S Pro Stage & Studio Silicone IEM Soft Ear Tips 3 Pairs for 4.5-5mm Nozzle, Headphone Eartips Replacement for Wireless/Wired Earphones (MS (Medium Small-3 Pairs))

Key features

• Six Sizes Available. SS (Extra Small), S (Small), MS (Medium-Small), M (Medium), L (Large), XL (Extra Large). S&S Pro is available in six sizes to accommodate a wider range of ear-canal sizes and shapes. More precise sizing helps achieve a stable fit and reliable seal for more consistent acoustic performance.
• Hexagonal Airflow Channels. Between the airflow channels, S&S Pro incorporates structural reinforcement ribs. These ribs separate the individual airflow paths and provide mechanical support around the front sound outlet, helping reduce local deformation caused by pressure from the ear canal.
• Six-Channel Petal-Shaped Sound Guides. Based on acoustic impedance and waveguide principles, the outlet of S&S Pro features six independent petal-shaped sound channels. By dividing the outlet into multiple controlled paths, the structure helps maintain a stable effective cross-section and guide acoustic energy more efficiently toward the ear canal, reducing transmission loss and high-frequency attenuation.
• Long, Straight-Barrel Design. S&S Pro retains the signature long, straight-barrel geometry of the S&S series. The extended profile allows for a deeper, more stable fit, helping maintain a consistent acoustic seal and reducing the effects of air leakage on bass response and overall tonal balance.
• Washable, Durable and Resistant to Aging. The high-durability medical-grade silicone used in S&S Pro offers excellent resistance to water, repeated handling, and long-term material aging. The eartips can be rinsed directly with clean water after use for routine cleaning and maintenance. Even after repeated washing and extended use, they are designed to retain their flexibility, sealing ability, and fit consistency.
