Development Story

Sony has brought together a wide range of technologies to create the Balanced Armature Headphone series, featuring the 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.

Discover an all-new experience with the exclusive Balanced Armature.
