Offers 11 headphones with micro-sized drivers
Sony has unleashed a new family of audio headsets for mobile users. The XBA series features the XB, a new micro-sized driver. In all, Sony has announced 11 models for music players and smartphones.
At the heart of the new headphones is Sony's new BA drivers. These micro-sized drivers offer the same dynamic response and sensitivity levels of 13.5mm drivers, but in a footprint one-quarter the size, the company claims.
The XBA-1, XBA-2, XBA-3 and XBA-4 headphones offer one (full range), two (full range plus a woofer), three (full range plus woofer and tweeter), and four (full range plus woofer, tweeter, and super woofer) BA driver units respectively. For smartphones like the iPhone, Sony is offering these four headsets in "ip" versions, which add the remote control of music players and hands–free talking.
For frequent exercise, Sony has created the XBA-S65, a washable and waterproof audio listening system. Sony has also folded BA technology into the XBA-BT75, a wireless Bluetooth headset. The BT75 builds the battery and control chip into headphones' housing, giving it an extremely compact shape.
The XBA-NC85D in-ear digital noise cancelling headphones are equally new and reportedly the smallest and lightest such devices on the market today. Sony claims a battery life for active noise cancellation of up to 20 hours and overall ambient noise cancellation at 97.5 percent.
The Balanced Armature headphones will be on the shelves of authorized Asian Sony dealers in November 2011. No word has surfaced as to when they will hit US shores, though most such releases arrive in the US.
