Sony IER-M9 5BA Flagship Detachable HiFi Audiophile In-Ear Earphone IEMs
Discover a new realm of musical expression
One stage, the IER-M9 in-ear monitor headphones authentically reproduce raw emotion and musical nuance.
Faithfully reproduce every performance
With a Penta Balanced Armature system including magnesium super tweeter, integrated magnesium inner housing and an optimized sound path, these stage monitor headphones faithfully reproduce even the most subtle sounds and emotions.
Penta Balanced Armature system for optimal stage sound
For clean high notes, natural tones, and the pure emotion behind every performance, the IEM-M9 has a Penta BA system including a magnesium super tweeter, Sony's original T-shaped Balanced Armature directly drivers the diaphragm for more linear motion, and clean, faithful high notes.
Magnesium diaphragm super tweeter
The IEM-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 film capacitor in the cross-over circuit delivers much lower distortion. The audio grade capacitor of the IEM-M9 delivers fine detail sound. Plus, audio grade solder also helps minimize any loss in signal path.
Beautifully designed for accurate tonal balance
With an integrated magnesium inner housing and optimized sound paths, the IEM-M9 headphones deliver balanced tones and every nuance of your performance.
Integrated magnesium inner housing to reduce vibration
A high rigid housing keeps the BA units firmly in place, helping to eliminate vibration and keeping sound clear without losing even the most minutes detail in your sound.
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.
Finer details and musical expression captures without loss
Sliver-coated oxygen-free 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 muscial expression
0.17" standard balanced connection cable separates left and right sound signals completely, which minimizes cross-talk that results in sound deterioration.
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.
The cable can be replaced if needed, or to fine-tune your monitor sound through a different cable.
