Sony IER-M9 Closed In Ear Earphone Monitor Headphone with Carrying Case (IER M9)
Faithfully reproduce every performance With a Penta Balanced Armature system including magnesium super tweeter, integrated magnesium inner housing and an optimised 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 IER-M9 has a Penta BA system including a magnesium 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 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.
