Monster announced some new additions to its Diesel VEKTR on-ear headphone line at CES 2013. Being the fashion brand that Diesel is, you can expect a couple of new colors to be added. First, the matte-finish Military Green with gun metal accents. If that's not your thing, there's also the new Chrome VEKTR, with it's eye-catching mirror finish. Both new models will sell for $279.95 when they go on sale later this Spring. If you're looking for something for traditional, a white model just went on sale for $269.95. All of these are in addition to the black Diesel VEKTR that launched last year.
