Performance evolved

Take your performance to the next level with IER-M7 in-ear monitor headphones, designed for musicians. With a precise sonic delivery and stable fit, you can fully express yourself with critical accuracy.


Premium technology enhances the live experience

From the Quad BA system, integrated magnesium inner housing and an optimized sound path, the structure of the IER-M7 is made from high quality parts. So you can trust them to make you sound your best.


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.


Sony's original design Balanced Armature (BA) Driver unit

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


Audio grade film capacitor for less distortion

Sony's custom audio grade film capacitor in the cross-over circuit delivers much lower distortion; the audio grade capacitor of the IER-M7 in-ear headphones delivers fine, relaxed 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 reduces vibration

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.


Subtle sounds and emotions delivered with no loss

Inheriting silver-coated OFC and a silk braid insulator from a top-of-the-line model, the cable of the IER-M7 delivers you your performance accurately.


Balanced connection available

A 4.4-mm standard balanced connection cable separates left and right sound signals completely, which minimizes cross-talk that results in sound deterioration.


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.


Detachable cable

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


Developed for even the most energetic performances

The IER-M7 in-ear stage monitor headphones are designed to stay firmly in place, so you can capture all the emotions you express in every performance.


Pre-formed ear hanger for ease and stability

The IER-M7 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.

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.
