Faithfully reproduce every performance
With a Penta Balanced Armature system including magnesium diaphragm super tweeter, integrated magnesium inner housing and an optimized sound path, these stage monitor headphones faithfully reproduce even the most subtle sounds and emotions.
Faithfully reproduce every performance
Penta Balanced Armature system for optimal stage sound
For clean high notes, natural tones and the pure emotion behind every performance, the IER-M9 has a Penta BA system including a magnesium diaphragm super tweeter. Sony's original T-shaped Balanced Armature directly drives the diaphragm for a more linear motion and clean, faithful high notes.

Magnesium diaphragm super tweeter
The IER-M9 super tweeter diaphragm is made of lightweight and rigid magnesium alloy to deliver the fast dynamic transient of performance. The unique BA unit design also benefits from extremely low resonance thanks to high internal loss. Internal wiring is upgraded with a new silver-coated copper voice coil and gold-plated terminals, faithfully reproducing sound without sacrificing even micro signals so pitch, harmonics, and emotion are portrayed.

Audio grade film capacitor for less distortion
Our custom audio grade film capacitor in the cross-over circuit delivers much lower distortion. The audio grade capacitor of the IER-M9 delivers fine detail sound. Plus, audio grade solder also helps minimize any loss in signal path.

Integrated magnesium inner housing to reduce vibration
A highly rigid housing keeps the BA units firmly in place, helping to eliminate vibration and keeping sound clear without losing even the most minute detail in your sound.

Balanced connection available
The IER-M9 In-ear monitors come with a 4.4-mm standard balanced connection cable which separates left and right sound signals completely, unlike conventional headphone cables where both channels share a ground wire. This minimizes cross-talk that results in sound deterioration.

Optimized sound path
A wide and short sound path made of magnesium alloy reduces frequency peaks and dips, to give a monitor sound you can rely on for critical listening accuracy.
Optimized sound path
Silver-coated OFC
Silver-coated, oxygen-free copper wire minimizes resistance and signal-transmission loss. The result is less sound degradation, finer detail and smoother treble sounds.

Detachable cable
The cable is fully detachable so you can replace it if needed, or fine tune your monitor sound through a different cable.

Preformed ear hanger for easy positioning
The IER-M9 In-ear headphones stably fit your ears through the universally shaped ear hanger. With firm fit and optimal housing shape, each ear bud stays in the right position.

Silk braid and non-magnetic undercoat plug
The IER-M9 uses silk braid as a cable insulator. This fibre works as an absorber against vibration and prevents rustling or bumping noises when you touch the cord. The gold plating of the plug has a non-magnetic undercoat which transfers the signal, preserving subtle nuances.
