Quad BA System For Faithful Monitoring
Evolve your musical expression through accurate and detailed monitoring with Quad BA system. Sony's original T-shaped Armature directly drives the diaphragm for more linear motion and clean, faithful high notes.

Audio Grade Film Capacitor
Our custom audio grade film capacitor in the cross-over circuit delivers much lower distortion. The audio grade capacitor of the IER-M7 delivers fine detail sound. Plus, audio grade solder also helps to minimize any loss in signal path.

Beautifully Designed for Accurate Tonal Balance
With an integrated magnesium inner housing and optimized sound paths, the IER-M7 headphones deliver balanced tones that enrich your musical expression.

Integrated Magnesium Inner Housing
The BA units are held firmly in a high-rigidity housing. This helps to eliminate vibration and keeps sound clear and clean without losing even a micro nuance of sound.

Optimized Sound Path
A wide and short sound path made of brass reduces frequency peak and dip, to give a monitor sound you can rely on for critical listening accuracy.

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 periods of time.

Stable Fit
The IER-M7 are designed to stay firmly in place with a snug fit for all ear sizes. With a firm fit and optimal housing shape, each earbud stays in the right position, even while moving on stage.
