The present invention is to provide one kind: can reduce the resistance of water or rain, wind； the consume of time caused by the resistance can be reduced in movement of racing etc.； and will not generate because be filled with power decline due to lead to the situation to fall off from ear； article contact can be reduced, hit generated vibration sound when earplug, be not easy to be conveyed to user's earhole and reach the earplug for the sense of hearing that adequately protects. In addition, forgetting in order to avoid above-mentioned earplug falls off, loses or puts, the present invention provides and is filled with tool on neck of the one kind with the earplug. Earplug of the invention is to be formed earplug body 1 connecting what arm 2 with 90 ± 45 degree of angle. Moreover, it and is formed earplug body 1 with 90 ± 45 degree of angle connection what arm 2, and the arm 2 is connected to wherein one end of what cotton rope 3. Earplug body 1,1 is connected into what arm 2,2 with 90 ± 45 degree of angle in addition, being formed, and the arm 2,2 is separately connected to the both ends of what cotton rope 3. Then, it is filled with tool on the neck with earplug of the invention, is to be filled with tool on the neck with earplug for link the cotton rope 3 of above-mentioned earplug.本發明是提供一種：可降低水或雨、風的阻力，在競速的運動等中可降低該阻力所導致的時間耗損，且不會產生因裝著力下降而導致從耳朵脫落的情形，可降低物品接觸、撞擊耳塞時所產生的振動聲響，不易傳達至使用者耳孔並達成充分保護聽覺的耳塞。另外，為了避免上述耳塞脫落、遺失或擱忘，本發明提供一種附有該耳塞之頸上裝著具。本發明的耳塞，是形成將耳塞本體1以90±45度的角度連接於臂部2。不僅如此，又形成將耳塞本體1以90±45度的角度連接於臂部2，且將該臂部2連接於線繩3的其中一端。此外，形成將耳塞本體1、1以90±45度的角度連接於臂部2、2，而將該臂部2、2分別連接於線繩3的兩端。接著，本發明的附有耳塞之頸上裝著具，是連結著上述耳塞之線繩3的附有耳塞之頸上裝著具。
