It’s right, you might have seen such types of cool Bullet Casing Earphones. But, most of them aren’t necessarily feature the original bullets. Apart from it, the inner satisfaction issue can only be resolved by doing it yourself with your two hands. This is all what made Igor from Inspiretomake create his own original bullet casing headphones. You can do it too if you have 2 buller shells (.40 Cal), old headphones, 10mm wooden dowel, sandpaper, hacksaw, drill machine and a soldering iron. These DIY bullet casing earphones look really great and sound amazing.
