Sennheiser HD-400 Pro

At first I was sceptical that these would be worth their money because I already have two other sets of studio headphones from different manufacturers, but these blew me away when I put them on. The open back design is phenomenal and the headphones work great together with Dearvr Mix to give you the actual feeling of sitting in a mixing room, unlike the other two pairs I own. These headphones aren't the fanciest, they don't fold or twist into a smaller size for easy travel, but what they do is deliver you a fantastic sound that let's you hear what you couldn't hear before. They're basically limited to a studio-like environment or for home use but I highly recommend you get yourself a pair and check them out yourself!
