Acoustune / RS ONE Graphite ACO-MONITOR-RS-ONE-GRY Canal type earphone

Variations

Acoustune's new line "Monitor" series first "RS ONE" is the brand's first stage monitor earphone that has both high durability and monitoring performance.

■ Highly robust body that is resistant to shock, heat and sweat
The number of parts is as small as possible, and market research is conducted to thoroughly research the fragile parts of the earphones to achieve a highly robust body. The housing consists of two parts and uses polycarbonate with excellent impact resistance, weather resistance, and heat resistance. By increasing the rigidity of each component in a simple manner, the risk of failure is greatly reduced even in harsh environments. The face plate plays a role in increasing the rigidity of the body while giving an identity as an earmoni. In addition, the housing design has a compact body that anyone can use widely.

■ "Milinks EL driver" that has both high input resistance and high acoustic performance
Acoustune is a brand based on its own dynamic driver, and uses the polymer biomaterial "Milinks" used for artificial skin and surgical sutures as the diaphragm material. The diaphragm, which is made by thinning this Milinks and optimized for the driver structure, has high strength and flexibility while being lightweight, and plays music with high resolution and wide dynamic range with excellent transient characteristics. RS ONE, which was designed as a stage monitor, has developed a new "Milinks EL driver" for RS ONE by utilizing the know-how of this Milinks driver. The Milinks EL driver realizes more accurate monitoring than the normal Milinks driver. The material used for the Milinks EL driver is an ultra-high-performance resin that is lightweight, extremely rigid, and has a large internal loss while being used for medical purposes, and boasts extremely excellent acoustic performance.Due to the large internal loss, unnecessary incidental noise is reduced and monitoring performance is improved. In addition, in order to make the best use of this Milinks EL driver, by securing a large back cavity on the back of the diaphragm and keeping a distance from the diaphragm to the grill, after a signal of up to 250 mW (*) is instantaneously input. However, it achieves high input resistance that can be used normally. As a result, even if there is a sudden large input such as howling on the stage, the earphone speaker gains robustness that is hard to break. Due to the large stroke width of the diaphragm, the sound has a live feeling just like a loudspeaker, but the accuracy of the earphones coexists, realizing excellent monitoring on the stage.

■ Impedance design that matches the wireless earphone system
Stage monitors are primarily used in combination with wireless earphone systems. If the impedance of this earphone system and the earphone do not match, it may be difficult to obtain the volume, or the characteristics of the earphone may change and the monitoring performance may deteriorate. In RS ONE, in order to avoid such troubles, impedance matching is performed accurately to thoroughly reduce compatibility problems with the earphone system.

■ Adoption of newly developed cables "ARM011" and "Pentaconn Ear Long-Type"
"ARM011" newly developed for RS ONE is adopted for the cable. A wire material woven with high-purity litz wire and Kevlar wire is used in a 4-core structure, and a PU material coating is used to improve maneuverability. By twisting this, it becomes a tough cable that is supple and easy to handle, yet has a habit and is hard to break. Considering compatibility with the use of the earphone system, the straight type is selected for the plug part. The connector uses the new IEM connector "Pentaconn Ear" connector designed and produced by Nippon Dics Co., Ltd., which boasts high sound quality and high reliability. Compared to the conventional MMCX connector, the plug part and the jack part are in closer contact, the conduction performance is excellent, and both ease of attachment and detachment and robustness are realized.Furthermore, RS ONE adopts "Pentaconn Ear Long-Type", which is a structure that is embedded in the body and prevents sweat from entering the connector part, as an important measure against sweat as a stage monitor. Compared to other connectors, it reduces the risk of wear due to attachment / detachment and use, contact failure due to sweat, and reduces accidents in the professional field environment. In addition, the structure is suitable for live environments because the cable can be easily attached and detached even if the wire is broken.

■ AET earpieces for high fitting and acoustic experience
The silicon earpiece "AET07", which is also used as a reference when developing Acoustune earphones, and the "AET02", which gives a feeling of sealing unique to the foam type, are included. Achieves high fitting while avoiding deterioration of sound quality. In addition, a carrying case is also included, making it easy to carry.

スタッフレビュー

このイヤーモニターの音の主張は中低音≧低音＝中音＝中高音＞高音という感じで、全体的に解像度、分離感が良く、定位がはっきりしていて、5人グループなどの複数人の声もそれぞれ聴き分けることができました。ボーカルが刺さることもなく、どんなに音量を上げても刺さりませんでした。
ただ、シンバル系の音が一歩後ろでなっているように感じられるため、ドラムをメインで聴く方や、派手さを求める方には少し物足りないかもしれません。そのおかげか、どの音域にも音が被っていることがないので、自分が聴きたい音をすぐに見つけることができます。
Pentaconn Earを採用しているので、万が一断線したとしてもリケーブルが可能なので安心です。キャリングケースも付いており、持ち運びも便利。同価格帯のイヤーモニターの新たな選択肢に加えてみてはいかがでしょうか。

シュアー425にLowを足した感じ

投稿者名Reviewed by：ちょっとよりみち【東京都】

Lowは40Hz周辺から80Hz辺りまでよく鳴ります。感覚としては30Hz辺り〜50Hz辺りも音源に入っていれさえすれば出ることは出ます。
Midはプレゼンスの帯域がやや強め、とくにMidHighの2.5k〜4.5k辺りが強い。サ行が目立つのではなく、タ行の「ツ」とか「チ」とかの歯擦音（のピーク）がやや目立つ。
Highは意識的にプラスして伸ばしてはいないと思います。「音源なり」に鳴ります。ちょっとシュアー的なドライでデッドな感じ。
音場は広くはない。ステージモニターのセオリーっぽくギュッとセンター寄り。ただ分離は良い。
プレゼンス帯の歯擦音ピークを抑えたい場合＆Lowをちょっと削りたい方は、イヤーピースをスパイラルドットプラスというやつに変えてみてください。相当聴きやすく、バランス良くなる。
