The PCS-250 Custom-Molded Earphones from Sonomax allow you to create earphones that fit perfectly. The included step-by-step guide shows you how to mold the silicone inserts to your ears' shape. Not only will your earphones stay in securely, but the custom fit also allows them to form an acoustic seal for a high degree of sound isolation. The earphones provide an extended frequency response and a powerful 115 dB SPL maximum output level. The single button in-line microphone provides compatibility with mobile devices so you can easily switch between listening and talking on the phone. Also included is a carrying case to protect your earphones when not in use.
