Sound Soldier Sport Plugs from Do-All Outdoors are as versatile as they are comfortable. They can be used simply as a passive plug or more depending on the position of the cap. Just snap the cap on the Hock filter closed and achieve an NRR of 24dB. Use as a noise filter with the cap open, or they can be used as a replacement plug for the Sound Soldier Digital BTE, as well as all Sound Soldier Boost Series BTE's. Simply pull the Hock filter and cap out of the plug and insert BTE acoustic sound tube into the Sound Soldier Sport Plugs for a comfortable and durable replacement tip. No special fitting required.
