4x Balanced Armature (BA) Units for Faithful Monitoring

Evolve your musical expression through accurate and detailed monitoring with the IER-M7 4x Balanced Armature (BA) Driver Units. Every emotion sound and tone are balanced and authentically reproduced consistently.

Sonys 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.

Integrated Magnesium Alloy Inner Housing

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

Audio Grade Film Capacitor for Less Distortion

Sonys custom audio grade film capacitor in the cross-over circuit delivers much lower distortion than ceramic capacitors. Suppressing vibration and electric interference the audio grade capacitor of the IER-M7 In-ear headphones delivers fine relaxed sound. Plus audio grade solder also helps minimize any loss in signal path.

Optimized Sound Path

While standard BA in-ear monitors rely on a long and narrow flexible tube in their sound path the BA drivers in the IER-M7 In-ear monitors use a wide and short sound path.

This reduces frequency peaks and dips and gives the ideal frequency response to ensure a monitor sound you can rely on for critical listening accuracy.

Balanced Connection Available

The IER-M7 In-ear monitors come with a 4.4 mm standard balanced connection cable which separates left and right sound signals completely unlike conventional cables where both channels share a ground wire. This minimizes cross-talk and the resulting sound deterioration.

Silver-Coated OFC

Silver-coated oxygen-free copper cables minimize resistance and signal-transmission loss. The result is less sound degradation finer detail and smother 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.

Preformed 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.
