XBA-300AP In-Ear Headphones
The XBA-300AP is the first Sony High-Resolution compatible in-ear headphones in the Balanced Armature unit line up, and features a Triple Balanced Armature – in addition to a full-range and tweeter, it adapts the symmetric armature and direct-drive structure to the woofer.
This new technology includes components that are fabricated to machining accuracy on the μ (micron) in order to drive the diaphragm faithfully to the input signal, delivering clear midrange and high-frequency sound. Moreover, its aluminium alloy diaphragm helps achieve weight reduction and high rigidity to deliver ultra-high frequencies while its brass sound path makes it possible for crystal clear high-mid notes.
The XBA-300AP also comes with a double layered housing. The inner housing, also known as “Rigid Mount Housing”, is composed by magnesium alloy that brings about high rigidity and high internal losses. The usage of different materials from outer housing sophisticates high-speed sound with a greater transient and also produces clearer sound in the mid-high range by inhibiting needless vibration inside the housing. The headphone’s noise-blocking design further attenuates ambient noise and sound leakage, offering you only the best in sound quality.
Equipped with a detachable cable, the XBA-300AP also enables you to enjoy an even better sound quality with a separate Sony cable, such as those from the MUC-M series. Its compact size also offers a perfectly comfortable fit, thanks to the efficient layout of the Balanced Armature driver that contributes to a stable and comfortable fitting.
