Sony has unleashed a new range of headphones, comprising of five new models. These are designed for listeners who like their bass heavy. The Sony XB Series - the XB standing for “extra bass” - consists of three circumaural style headphones and two in-ear style, with brushed metal accents and exclusive Bass drivers.
The five-model XB range is headed by the closed-type MDR-XB700, with extra-large 50mm dome-type drivers, “king sized” synthetic leather ear cushions and an extra-wide headband to spread out weight. The MDR-XB700, MDR-XB500, MDR-XB300 are wide headband headphones, while the MDR-XB40EX and MDR-XB20EX are in-ear headphones. These latter in-ear models claim to deliver good bass due to ‘direct vibe’ acoustic design that minimizes sound spillage. The vertical driver orientation (with MDR-XB40EX only) claims to deliver extended bass without compromising listening comfort.
The Sony XB Series headphones will go on sale from March 2009. Sony is yet to reveal pricing for the range.
