The new XB Series headphones from Sony are specially designed to produce powerful bass thanks to its extra-large 50mm dome-type driver that produces ultra-low frequencies. Its optimized bass performance is balanced by clear reproduction of high-and mid frequencies. The Sony MDR-XB700/500/300 headphones also feature brushed aluminum accents and durable new flat-section cord. The MDR-XB series of headphones are expected to be available from March 2009. [Sony]
