The Earphone Connection Torpedo Earbud (3-Pack) delivers lasting comfort, clear audio and situational awareness. Attach to any two-way acoustic tube earpiece. Easy to clean. Replaces standard mushroom style eartip. The flexible silicon fins contract or expand when necessary. The soft silicon Torpedo eartip is easy to clean with water or an alcohol swab. Air passes through the fins allowing sound to enter the ear canal evenly to prevent noise from being trapped like most conventional ear buds. With the universal fit of the Torpedo Ear Bud, it is easy to attach to most sound devices with an acoustic tube.
