Ear tips designed for wired earphones. The inner tube diameter is 4 mm, or 3 mm when the nozzle adapter is attached. Each set includes one pair of ear tips and one pair of nozzle adapters in the same size. Made from proprietary silicone material, these ear tips reduce discomfort and itchiness often felt during long listening sessions, ensuring a comfortable fit for extended use. They enhance high-frequency sound reproduction, allowing finer details of the music to be heard more clearly. The result is greater musical expressiveness with well-balanced resonance from instruments. The durable structure securely supports the weight of wired earphones, providing a snug fit that helps prevent them from slipping out of the ears.
