The MDR-Z7M2 features all-rounded improvements over its predecessor and continues to feature a 70mm driver. The HD driver, however, spots an aluminium coated Liquid Crystal Polymer diaphragm, in which the dome is upsized and its profile is optimised, is one of a number of features adopted from the MDR-Z1R which also included the introduction of a Fibonacci-patterned grill made of stiff resin to achieve both thinness and strength whilst minimising sound damping from the grill in the ultra-high frequencies resulting in smooth sound reproduction across all frequencies.

In addition, the MDR-Z7M2 features Beat Response Control, a special acoustic port on the housing, controls air flow behind the driver and optimises diaphragm movement when reproducing low frequencies which Sony claims to improve the transient characteristics in bass sounds and delivers the rhythm in music accurately.

To minimise loss in the signal path and ensure purity of contact, non-lead audio grade solder and corson alloy which is known for its low resistance value and high durability is used for contacts of the jacks.

The MDR-Z7M2 comes with two sets of headphone cables; a 3m 3.5mm single-ended cable and a 1.2m 4.4mm balanced cable. A screw lock-ring mechanism is used to secure the connection and enhance durability. In addition, a silver coating was used for the balanced cable to allow for finer details, smoother treble, and less sound degradation.

The MDR-Z7M2 features three-dimensional sewing, ergonomically shaped ear pads, and aluminum alloy hanger and slider for lightweight are improvements to ensure a higher level of comfort even during long periods of wear and less pressure on the head over its predecessor.

According to Sony, three-dimensional sewing on the ear pads ensures an ergonomic shape designed to fit the unevenness of the head and gives even pressure throughout the area. This reduces sound leakage by increasing air-tightness, delivering powerful heavy bass to the listener. Soft urethane foam cushion with moisture absorbing and releasing characteristics was chosen for the surface of the ear pads to reduce the feeling of stuffiness and provide a comfortable extended listening experience.

A synthetic leather headband with aluminum alloy hanger and slider ensures the MDR-Z7M2 is lightweight yet durable for years to come. A special anodising treatment process resulted in increased hardness of the hanger while minimising scratches caused by daily use. Special attention was paid to designing an enfolding structure for the MDR-Z7M2 where ear pads slant inwards due to side pressure during wear. This created a tighter air seal which enhanced deep bass production and minimised sound leakage, providing the listener with improved comfort and stability during wear. The MDR-Z7M2 also features a silent joint mechanism that minimises mechanical noise caused by the movement of joints ensuring a quiet listening experience for the most discerning listener.

Priced at SGD 1,199, the Sony MDR-Z7M2 will be available at selected Sony Stores, Sony Centres and Sony authorised dealers from the end of September 2018.
