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
With 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, and the audio-grade capacitor of the IER-M7 In-ear headphones delivers fine, relaxed sound. 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 silk braid insulator from a top-of-the-line model, the IER-M7 cable accurately delivers the performance you need.
Balanced connection available
A 4.4-mm (0.17-in) standard balanced connection cable completely separates left and right sound signals, 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.
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 fit firmly in your ears with the universally shaped ear hanger. With a firm fit and optimal housing shape, each earbud stays in the right position.

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.
