Penta Balanced Armature system for optimal stage sound

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

Detachable cable

Detachable cable

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

Pre-formed ear hanger for easy positioning

Pre-formed 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.

13 variations of earbuds

13 variations of earbuds

Our earbuds come in thirteen variations - six triple comfort and seven hybrid silicon. So you can find a snug fit for all kinds of ear shape. Combining hard silicone rubber and specially-developed formed silicone, they perfectly match sound with stability and are comfortable to wear for long lengths of time.

Designed with professionals

Designed with professionals

We developed these in-ear monitor headphones cooperating with professional musicians and live-sound engineers. Their opinions are reflected in this product.

Magnesium diaphragm super tweeter

Magnesium diaphragm super tweeter

The IER-M9 super tweeter diaphragm is made of light weight 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

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 minimise any loss in signal path.

Integrated magnesium inner housing to reduce vibration

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.

Optimised sound path

Optimised 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.

Balanced connection available

Balanced connection available

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

Silver-coated OFC

Silver-coated OFC

Silver-coated oxygen-free copper wire minimises resistance and signal-transmission loss. The result is less sound degradation, finer detail and smoother treble sounds.

Silk braid and non-magnetic undercoat plug

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.

Finer details and musical expression captured without loss

Silver-coated oxygen-free copper cables, a natural silk braid cable insulator with non-magnetic undercoat plug and a 0.17" standard balanced connection cable give less sound degradation, finer detail, and faithfully reproduced musical expression.
  • 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.
  • Silk braid insulator and non-magnetic plug

    Vibration is absorbed by the silk braid cable insulator to minimize rustling when the cord is touched. A gold-plated plug with non-magnetic undercoat preserves signal purity.
  • Detachable cable

    The cable can be replaced if needed, or to fine-tune your monitor sound through a different cable.
