Experience Balanced Armature Headphones
Sony has brought together a wide range of technologies to create the Balanced Armature Headphone series, featuring the world’s only Balanced Armature (BA) drivers optimized for music enjoyment. Because these driver units can be freely tuned, they are capable of a wider range of sound, and by combining full-range, woofer, super woofer and tweeter units, they can be layered together for a highly nuanced sound experience. Thanks to the driver’s micro sized construction and high sensitivity, these headphones are able to maximize style comfort, sound insulation, sound leakage prevention and even waterproofing, all while providing great sound quality. Sony BA headphones deliver a new high-quality music listening experience.
Double Layered Housing
The combination of Magnesium inner housing and a special ABS outer housing reduces unwanted vibration and realises smooth sound response to reproduce clear and distortion-free sound, especially in the mid to high range. Double Layered Housing Design allowed Sony to achieve superior sound quality and noise reduction.
High sensitivity for such a compact size
Clear output across a full sound range
|Drivers ||Volume ||Sensitivity |
|13mm Dynamic ||340mm3 ||106dB/mW |
|09mm Dynamic ||130mm3 ||100dB/mW |
|BA ||80mm3 ||106dB/mW || |
Sony's Balanced Armature Drivers are 40% smaller than the traditional 9mm Dynamic Driver Units. The smaller size allows a design that creates a better fit inside the ear. This attenuates the outside sounds better than headphones with Dynamic drivers, resulting in a superior listening experience.
Compared to Dynamic drivers, BA drivers have an even response across the frequency range, with low and middle vocal ranges standing out. The sound has a very precise feel. BA drivers can be tuned for higher or lower ranges and combined to emphasize certain sounds.
