Stick these bullets in your head and you’ll get awesome sound quality for an ear-bud headphone. Munitio didn’t miss a beat when building these headphones. They have an industrial grade titanium coating, which is used by NASA in high performance applications, which offers unmatched durability. These 9mm drivers also employ the BassEnhancingChamber™ which will feel like an earthquake in your head. Kevlar reinforced cable helps protect the cable from stretching and breaking. Like I said: bullets, Kevlar, titanium – only the best. Few more color choices available such as chrome and black.
