This blog is no stranger to sticking spent casings in your ears. I observed R. Lee Ermey using some for hearing protection, and also found a tutorial on how to accomplish it.
Makes me wish I would have thought of this idea, to deliver sound to the user, rather than mute everything. According to Gizmodo, the earphones are made by a company called MUNITIO, and will apparently be sold for $250 each. They better sound damn good for that money.
Unless you are a massive company like apple, sony, google etc.. I never understood why you would want to talk about your products and create buzz before they are even available. Anyone that thinks these headphones are an awesome idea, would probably want to purchase them immediately and not have to keep checking the website for an update on the magical date they will be available. Maybe the average consumer isn’t like me though. I will have long forgotten about these within a couple of days.
