20 February 2012, Singapore – Sony equips its latest range of in-ear headphones with the new micro-sized Balanced Armature technology.  This technology delivers high performance sound quality in a compact and lightweight body. 11 models of the new Sony XBA range of in-ear headphones were recently launched allowing you to have a high quality audio experience under various lifestyle needs which includes noise cancelling, Bluetooth and waterproof sports models.

For Your Daily Pleasure

Sony developed a full suite of high quality sound models with sound preferences and budgets of consumers in mind. Featured with different Balanced Armature (BA) drivers ensembles, the XBA-1, XBA-2, XBA-3 and XBA-4 headphones encompass one (full range), two (full range + woofer), three (full range + woofer + tweeter), and four (full range + woofer + tweeter + super woofer) BA driver units respectively – producing crystal clear sound reproduction and quality across the range of frequencies. The ability to combine woofer and tweeter drivers in addition to the standard full-range driver, would also greatly appeal to music lovers seeking an even more intensely satisfying listening experience, with bass and treble frequency ranges reproduced in even higher-fidelity.
