Sony’s original design (BA) Driver unit
The unique T-shaped Balanced Armature directly drives the diaphragm for a more linear motion and clean, faithful high notes.
Integrated magnesium alloy inner housing
The BA units are held firmly in an integrated, high-rigidity housing. This helps to eliminate vibration and keeps sound clear and clean without losing even a micro nuance of sound.
