  • 5x Balanced Armature (BA) units for optimal sound design

    For clean high notes, rhythm, pitch and the pure emotion behind every nuanced performance, the IER-M9 has 5x Balanced Armature (BA) Driver Units, including a Magnesium alloy super tweeter.

  • Sony's original design Balanced Armature (BA) Driver units

    The unique T-shaped Balanced Armature directly drives the diaphragm for a more linear motion and clean, faithful high notes.

  • Magnesium alloy super tweeter

    The IER-M9 super tweeter diaphragm is made of light weight and rigid Magnesium alloy to deliver the responsiveness required for describing subtle music nuance. The unique BA unit design also benefits from extremely low resonance thanks to a high internal loss. Internal wiring is also upgraded, with a new silver coated copper voice coil and gold-plated terminals, to faithfully reproduce sound without sacrificing even micro signals – so pitch, harmonics, and emotion are portrayed.

  • Audio grade film capacitor for less distortion

    Sony’s custom audio grade film capacitor in the cross-over circuit delivers much lower distortion than ceramic capacitors. Suppressing vibration and electric interference, the audio grade capacitor of the IER-M9 In-ear headphones delivers fine, relaxed sound. Plus, audio grade solder also helps minimize any loss in signal path.

  • 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.
