Two Heads Earplug / Earplug

Two Heads Earplug
Two Heads Earplug

There usually are two using patterns for the earplug, those are, ordinary one and in-ear one. The in-ear one is suitable for being used in the noisy environment because it could reduce the noise greatly. The ordinary one is more comfortable for long time use, which is better to be used in relatively quiet environment. The Two Heads Earplug combines the both types together by a special removable head. It could switch between the two types freely, makes it more convenient and comfortable for the user.
