The Electrowave looks to be their premier set of 50mm headphones with a metal construction and lots of durability, while the new Redphone is a single high-quality 50mm driver headphone for those DJ's who like to monitor with one ear while listening to the live sound with the other. The Electrowave Pro headphones will clock in at $150 while the Redphone will sell for around $70. Check out the press release and specs below for more information.
