■ Product Description ■ SONY noise isolation ear tips. Size: S. Noise isolation ear tips designed for sound isolation. Hybrid ear tips combining two types of silicone with different hardnesses. The core uses a hard material to maintain the shape of the sound passage and prevent sound quality degradation due to tip collapse. The outer part uses a soft material to improve the fit to the ear. Increased sealing for comfortable wear even for long periods. Furthermore, the low-rebound urethane foam inside the ear tip equalizes pressure on the ear canal and conforms to fine irregularities. This improves sound isolation by fitting the ear better than conventional ear tips. Recommended for those who want to improve their sound. The condition shows some signs of use. ■ Please bid or purchase if you understand the current USED condition.
