Sony introduced two new premium in-ear stage monitor headphones, the IER-M9 and IER-M7. Both in-ear stage monitor headphones are able to provide the best tonal balance for monitoring your play on stage with absolute sound isolation and a stable fit to avoid the headphones falling off during performance.
The headphones are developed to monitor even musical expression with addition to tone color and rhythm. With the IER-M9 and IER-M7, audiophiles will also be able to experience first-hand this musical expression tuned for professionals.

The IER-M9 features a Super Tweeter with magnesium alloy diaphragm, Penta BA system in a magnesium alloy inner housing, and a housing-integrated sound path made of a light and durable magnesium alloy outer housing.
