Sony pumps up the bass
Firm's cans promise all-mighty bass
Music with a bangin’ bass is important, or so Register Hardware’s intern said. Sony obviously knows this too, because it’s launched a series of eXtra Bass (XB) headphones.

Sony's eXtra Bass cans boast bangin' bass beats
The cans are designed to accurately reproduce ultra-low frequencies without compromising crystal-clear mid-range vocals and high-frequency sounds, Sony claimed.
Of the five models available, all three cup-style cans have a synthetic leather covering. The flagship MDR-XB700 headphones have a 50mm dome driver, while the MDR-XB500 and MDR-XB300 models have 40mm and 30mm dome drivers, respectively.
Sensitivity across all three ranges between 106 and 100db/mW, but while the MDR-XB700 and MDR-XB300 cans both have a 24ohm impedance setting, the MDR-XB500 supports 40ohm.

Synthetic leather. Classy...
The two remaining models in the XB range feature an in-ear design with 13.5mm and 9mm dome drivers respectively. The latter model, the MDR-XB20EX, has a 103db/mW sensitivity, while the 13.5mm MDR-XB40EX has a 105db/mW sensitivity. Both have a 16ohm impendence.
All four come with a gold-plated L-shaped stereo plug and a 1.2m cord. The two in-ear XB models also ship with a carrying case.
Sony’s XB range of headphones will be available next month, but a price hasn’t been announced yet. ®

Said intern probably also yearns for a car with an exhaust note that is guaranteed to produce headaches after 45 minutes of expressway travel. If said intern could afford the petrol for 45 minutes of travel, that is.
Interns in general shouldn't open their yaps until they catch a bad case of clues ...
