Sony releases XBA balanced armature headphones, eleven times over

This dizzying array might seem like overkill, but Sony's premium "Experience Balanced Armature" (XBA) 'phones are carefully targeted at different price points and types of listener. You've got the entry-level XBA-1 containing a single full-range driver. Add a woofer for bigger bass and you get the XBA-2. The XBA-3 also squeezes in a tweeter for high-freq perkiness, while the XBA-4 rounds it all off with a super woofer. Each pair also has a smartphone twin with inline controls, denoted by the iP suffix. Finally, there's a trio of single-driver specialists: the noise-cancelling XBA-NC85D, the sporty XBA-S65 with basic waterproofing for sweat and rain, plus the Bluetooth XBA-BT75. It's unclear when these will hit our hemisphere, but we're looking at a November release in Hong Kong and Taiwan with prices ranging from 3,000 to 14,000TWD ($100 to $475) depending on the model.
