What is Balanced Armature?
The makings of superior sound quality.
Balanced Armature Drivers have a high-precision design. Its unique sealed casing features a spring force and magnetic pulling force, which are balanced on the armature - allowing it to move freely and produce optimal audio quality. Balanced Armature drivers also offer greater flexibility and can be specifically tuned for higher or lower ranges and combined to emphasise certain sounds. This enables precise control over the sound quality.
