SONY / IER-M7 Earphones

Everything is done to deliver the best performance on stage. We pursue the high quality sound and accurate reproduction of the original sound that artists require.

○Newly designed multi-BA system
Each of the many BA driver units has its own role and complements the sound.
Realizes the high sound quality required for IEM (inner ear monitor).

○Quad balanced armature driver unit
Excellent separation between vocals and each instrument, and allows you to accurately grasp the onset of the rhythm.
In addition to the optimal sound quality for monitoring, it also has high sound insulation, making it the best monitor earphones for live stages.
Equipped with four BA drivers in the following configuration.
・Full range x 2
・Woofer
・Tweeter

○Magnesium inner housing
The inner housing that secures the driver is made of high-rigidity magnesium alloy.
By firmly securing the driver and suppressing vibration, the transparency of the sound is increased.

○Brass sound guide tube
Brass is used for the sound guide tube through which the sound passes from the driver to the outside.
By expanding the inner diameter while maintaining strength, we have achieved a clear mid-to-high range with a long range.

○Silver-coated OFC wire
The included cable uses a double-structure conductor with a pure silver coating on the surface of oxygen-free copper.
Signal transmission loss is minimized to the utmost, reducing sound deterioration.
Realizes particularly smooth high-pitched sound reproduction.

○Φ4.4mm balanced standard plug adopted
In addition to the general 3.5mm stereo mini plug cable, 4.4mm balanced plug cables can also be used.
High-quality balanced playback is possible with Walkman and headphone amplifiers that support the 4.4mm balanced plug standardized by JEITA.

○Detachable cable

○Noise blocking structure
Housing structure that thoroughly pursues sound insulation. Suppresses surrounding noise and prevents sound leakage.
