Mostly known for its extravagant speaker systems, KEF is finally taking a whack at ear gear. Today, the company announced two new types of HiFi headphones, known as the M Series, which include a pair of on-ear cups (M500) and a set of in-ear buds (M200). Priced at $300, the M500 sports a full aluminum frame and sweat resistant padding, along with a 10mm driver for lows and a 5.5mm driver for mids and highs in each earcup. If enclosed head gear isn't your thing, the $200 M200 offers an aluminum housing and a pair of silicone ear tips with an adjustable arm for improved comfort. Like their pricer sibling, these earphones also feature a dual-driver system. While we've yet to spend time with the M500 or M200, their press pictures and specs aren't too shabby. Call it a hunch, but we doubt they'll need any celebrity endorsements.For more info on KEF's new headphone line, hit the presser after the break.
