Sony IER-M7

The Sony IER-M7 is a pair of in-ear monitor headphones designed for musicians and discerning audiophiles who require accurate and precise sound reproduction for critical listening. It features a quad Balanced Armature (BA) driver system and an ergonomic design for a stable and secure fit, ideal for on-stage performance.

Key Features

• Quad Balanced Armature (BA) System:
  • Equipped with four BA drivers per side to deliver a wide frequency response and a well-balanced sound signature.
  • Sony’s original T-shaped Armature design directly drives the diaphragm for more linear motion, resulting in clean, faithful high notes.
• Integrated Magnesium Inner Housing:
  • The BA units are held securely in a high-rigidity inner housing made of magnesium.
  • This construction helps to eliminate unwanted vibration, ensuring clear and pristine sound without losing a single nuance.
• Audio-Grade Film Capacitor:
  • The crossover circuit utilizes a custom-built, audio-grade film capacitor.
  • It delivers significantly lower distortion than conventional ceramic capacitors, providing a fine, relaxed sound.
• Detachable Cables:
  • Comes with two detachable cables: a standard 3.5mm stereo mini plug cable and a 4.4mm balanced standard plug cable.
  • Both cables feature silver-coated oxygen-free copper (OFC) strands to minimize resistance and signal transmission loss, leading to less sound degradation and finer detail.
• Stable and Secure Fit:
  • The headphones are ergonomically shaped to fit a wide range of ear sizes.
  • The preformed ear hanger ensures a stable and comfortable fit, even during active movement on stage.
