Hi-Res high-resolution sound quality

Headphone form: closed, hybrid

Frequency Response: 3 Hz~100,000 Hz

As the first in-ear headphones in Sony's flagship Signature series, the IER-Z1R has two built-in dynamic driver units, with a hybrid driver unit structure with a balanced armature. The ear shells are made of high-rigidity top zirconium alloy. The BR1005 also adds the fish scale totem design that has appeared in high-end watches on the outside of the round ear shell. As for the inside of the ear shell, it is made of aluminum alloy, which can reduce unnecessary vibration in the cavity. The IER-Z1R adopts a new around-the-ear wearing design, and it also comes with 6 sizes of triple-comfort earplugs and 7 different sizes of hybrid silicone earplugs.

The left and right ear separate headphone cable is configured, and is equipped with a 3.5mm plug headphone cable and Sony's exclusive 4.4mm plug balanced headphone cable. Both headphone cables are made of silver-plated oxygen-free copper, which is suitable for the electroplating of plugs and mmcx terminals. Sony developed a gold-plated material with an undercoat to replace magnetic materials such as nickel that would disrupt signal flow.

The IER-Z1R is equipped with a newly developed aluminum-coated liquid crystal polymer diaphragm, a 5mm dynamic driver unit composed of an external magnetic circuit, and a 12mm dynamic driver unit made of magnesium dome and aluminum-coated LCP Single unit configuration, the former masters high-frequency audio, while the latter brings a rich sense of low and medium volume. In addition, the balanced armature unit designed and produced by Sony together forms the new hybrid drive system of IER-Z1R. As for this balanced armature unit, it can bring clear high audio performance to the listener.

In addition to the new hybrid drive system, Sony has also improved the airflow control system for the internal cavity of the IER-Z1R ear shell, which can control the airflow behind the driver unit, thereby connecting the sound tube to the sound cavity that extends behind the driver unit. to control the sound performance. In addition, the IER-Z1R is also equipped with audio-grade film capacitors and dedicated high-grade audio solders to reduce losses in the signal path and ensure sound purity during connection.

I paired the Sony Signature NW-WM1Z music player with a 4.4mm headphone cable to listen to the Hi-Res high-resolution sound quality music at the scene. In the short audition time, I will bring you a simple listening experience sharing, first of all, you can listen to it as soon as you put it in your ear. I can feel the vast sense of space brought by the IER-Z1R, and with the surround sound field configuration, although it is still a little far to catch up with the listening sense of the MDR-Z1R over-ear headphones, it is 70~80% overall. close.

IER-Z1R also has a clean and natural sound performance, which is the so-called full of air, the sound analysis ability is quite good, the detail presentation of the instrument is quite layered and rich, the treble is crisp and not cloudy, and the midrange is solid and tight. , with the bass with sufficient diving depth and extension, although the bass strength is slightly insufficient, the overall sense of hearing is quite comfortable and durable, suitable for listening and appreciation with symphony, movie soundtrack or vocal-based music types.

The Sony IER-M9 monitor headphones also use an in-ear headphone structure with a new around-ear design. The ear shells are made of lightweight magnesium alloy and have a special textured surface design. The IER-Z1R is different.

The IER-M9 is built with 5 magnesium alloy balanced armature driver units developed and produced by Sony. It is a five-way drive system structure with 1 bass, 2 midrange, 1 treble and 1 super tweeter, which can make the sound performance more accurate. Clear, while retaining more sonic detail, and also featuring Sony's audio-grade film capacitors for crossovers.

The configuration of the audition also uses the NW-WM1Z music player and the 4.4mm plug headphone cable to play Hi-Res high-resolution sound quality music. The IER-M9 has a very bright rhythm, and the separation of each audio is quite sufficient. Demonstrate its design tonality as a monitor headphone. The ability to analyze sounds is better than the IER-Z1R. It can more faithfully present the details of musical instruments and vocals, but it also lacks the rich layered sense of hearing that is connected with each other.

The IER-M9 also has the usual cool sound of monitoring headphones, but strictly speaking, it does not sound as bad as ordinary monitoring headphones. There are two more balanced armature monomers for the main high-frequency audio. The sound is cleaner and clearer, and it also improves the resolution of the sound. This headset is more suitable for live performance versions of songs, or performance songs composed of multiple instruments.

Sony IER-M7 Monitor Headphones

Key specs:

Hi-Res high-resolution sound quality

Headphone form: closed type, four-balanced armature

Frequency Response: 5 Hz~40,000 Hz

Sensitivity: 103dB/mW

Impedance: 24 Ω

The Sony IER-M7 is another monitor headphone with the same design as its sibling, the IER-M9, but the ear shell does not have a fish scale totem design, but a mirror-coated design with a design style similar to that of the IER-M9. obvious difference.

IER-M7 also comes with 6 sizes of triple comfort earplugs and 7 different sizes of hybrid silicone earplugs. It also adopts a separate headphone cable design, and also attaches headphone cables with 3.5mm and 4.4mm plugs. The wire is also made of silver-plated oxygen-free copper wire.

Compared with the IER-M9, which is equipped with five balanced armatures, the IER-M7 has four built-in magnesium alloy balanced armature units newly created by Sony, which are a four-way drive system structure for bass, 2 midrange and 1 treble. , with brass airflow conduction path, and high-quality loop design.

The configuration of the audition is the same as the above two headphones. The IER-M7 also has quite good separation of music, but the overall listening sense is not as strong as that of the IER-M9, and the sound analysis ability is also quite good, which is similar to the IER-M9. The difference in the sense of hearing is that in the performance of the high-frequency part, there is a lack of a balanced armature responsible for the treble, so that there is still a little difference in the clarity of the treble and the overall music details. The IER-M7 also has the cool listening feel of the monitor headphones, but it is not as obvious as the IER-M9, but it is enough to handle different styles of music.

Sony MDR-Z7M2 Over-Ear Headphones

Key specs:

Hi-Res high-resolution sound quality

Headphone form: closed type, dynamic type

Drive unit: 70mm

Frequency Response: 4 Hz~100 kHz

Sensitivity: 98dB/mW

Impedance: 56 Ω

Output power: 2,000mW

After continuing the previously well-received MDR-Z7 over-ear headphones, Sony launched the newly evolved follow-up MDR-Z7M2 over-ear headphones at this event. The Z1R has numerous specifications and technologies, and is enhanced for wearing comfort.

The appearance design of MDR-Z7M2 is not much different from the previous generation MDR-Z7. It adopts specially thickened low-rebound ear pad design, and uses aluminum alloy headband and adjustable slider configuration. In addition, when the headset is folded The structure of the rotating shaft is specially designed to be inclined inward, which can increase the fit when wearing and prevent the occurrence of sound exposure.

Under the earphone shell, a special rhythm response control acoustic port is also added, which can control the airflow behind the unit, control the airflow resistance in the bass range, and also optimize the diaphragm to improve the transient performance of the bass.

The MDR-Z7M2 is equipped with a standard 3.5mm unbalanced cable and a 4.4mm balanced terminal cable, and adopts a screw-type locking ring disassembly and assembly design, and the cable uses a silver-plated copper cable.

The MDR-Z7M2 uses a new 70mm driver unit developed at the same level as the MDR-Z1R, with an aluminum-coated liquid crystal polymer diaphragm, and an enlarged dome size profile. The former can reduce sound coloration in the mid-high range, while the latter can Helps clear sound quality in low to mid audio. In the new drive unit, it contains about twice as many magnets than the previous generation, and also uses the Fibonacci golden section frame made of rigid resin, which can take into account both thinness and sturdiness.

However, due to the limited time for the experience, the editor was too late to conduct an audition. Please wait patiently for the listening experience of the experience tomorrow.
