Any pair of headphones that took two years to be developed are probably going to be some finely-tuned audio devices. Either that, or they are going to be terrible and the company kept screwing things up for 24 months. Knowing Nocs, the new NS900 Live Headphones will be the former. The DJ headphones sport two 40 mm custom-designed titanium drivers, interchangeable cushions, and a PVD-coated stainless steel band kept in place by steel hex screws. The cable lock system ensures your cable stays in when you’re listening or performing and the NS900′s come with interchangeable cords for whatever device you’re using. Even if you’re not bringing some Technics to the club, these are solid headphones.
