The Otto Noizebarrier Micro High Definition Electronic Earplugs are a personal favorite here at Spartan Defense Network. Otto Engineering has done a phenomenal job once again. After years of trying quite literally every in-ear electronic hearing protection made, we finally found a product that we are proud to sell. The ear plugs hold up to 16 hours of life, and the battery case provides 20 recharges. So, you get up to 320 hours of use with your earpro, before you need to plug your case back in.
