BSEP for Z1R earphone re-cable for SONY IER-Z1R earphones

The Brise Audio team has designed this re-cable to take full advantage of the IER-Z1R's unique sound quality.
　We have been using the IER-Z1R as one of our reference earphones as a test device for product development since its initial release.
　*IER-Z1R is a product of SONY.Click here for product information on IER-Z1R

・定評のある4芯YATONO線材を使用、 Z1Rの特徴である輪郭のしっかりした高域・低域を より活かすべく、
　Exclusive and original high sound quality construction

Same material as top grade MURAKUMO (CNT)note 1Special Electromagnetic Wave Absorption Shielding Material※2BS Sheet*3(including the following), and
　Ref.2グレードと同等以上の 高音質化施工を実施

IER dedicated terminals are used (because MMCX may damage the female terminals).

Brise Audio's original 4.4mm, 2.5mm, 3-pole 3.5mm, and 4-pole 3.5mm plugs (also supports GND separation) can be selected.

The sound we aimed for with the dedicated cable BESP for IER-Z1R is as follows.

　≪ ≪ Our interpretation of the IER-Z1R's sound quality.
　≪ → The sound we aimed for with this cable.
 
　0The sound image has a firm contour and is rich in crispness.
　→The following is a summary of the information in a way that is not cumbersome while increasing the amount of information to make the most of its features.
　　We aimed to create more texture.

　0The high frequency range has a sparkling and unique charm.
　→We aimed to further develop these characteristics.

　0Rich low frequency with volume
　→Tightened tight to make it easier to feel the kick and bass line.

　0Type that firmly localizes the sound in the foreground instead of expanding the sound field
　The goal was to clarify the sound image and increase the sense of realism while maintaining the same → characteristics.

　0 wide bandwidth
　→Without narrowing the bandwidth, we aimed for a fuller mid and low frequency range.


※1
　In order to take advantage of the excellent properties of CNTs, we have developed the optimum material through repeated joint tests and comparative audits conducted by a national research institute and a cooperating material manufacturer. Excellent shielding capability. Excellent shielding ability. Various other useful physical properties. (The properties of CNTs vary depending on whether they are single-phase or multi-layered.)

 ※2
　 It is a material that absorbs electromagnetic waves and converts heat, which is very effective especially in the high-frequency band, consisting of seven layers. This is the core material used in all our high-grade cables, including our flagship cable MURAKUMO.

 *3
　BS sheet is a material that boosts the positive sound quality effects of other materials while having very little negative impact on sound quality.

The adopted cable slider is

We carry out all processes and production domestically. It also has the effect of a vibration stabilizer. We have considered and adopted various materials.

Adopted BriseAudio original L-shaped plug

We have developed and adopted the BriseAudio original L-shaped plug with the aim of improving sound quality and convenience. Not only in terms of sound quality, but also it is a high-quality plug with a very high-quality feel, taking into account the ease of use.
In addition to L-type terminals, straight terminals are also available at the official store.
