Description: Maestraudio MA910SR In-Ear Monitor Pentaconn ear connector Blue / OTA-MA910SR-GB.(released on April 15th 2023 in Japan)DescriptionMA910SR Development BackgroundThe first Maestraudio model, the MA1S, incorporates a head transfer function into the design and is equipped with the original passive ceramic tweeter RST, aiming to achieve a natural sound throughout the entire range and a wide soundstage.And it was well received by many users as a high-performance IEM that does not tire of listening.However, at the same time, we received many requests for recable models from users who pursued more personality sounds.Therefore, while maintaining the widest soundstage of the MA910S class, we repeated research and prototypes with the aim of reducing contact resistance loss due to recabling and acquiringmore informative sound quality, and this time, Maestraudio's first recable-compatible model "MA910SR" will be a model that symbolizes the brand. We have succeeded in developingRecable support with Pentaconn ear connectorWe conducted verification with various connectors to support recable.The MA910SR uses a Pentaconn ear connector, which has a reputation for low contact resistance, for the recable connector.This connector not only has stable mechanical reliability when attaching and detaching, but also makes it possible to reduce the contact resistance to less than 1/10 that of MMCX, which is a general recable connector.In recable models that can enjoy various sound qualities, reducing contact resistance is an important design requirement in order to enjoy the characteristics of various cables.In the MA910SR, the cable is finished in an IEM that allows you to enjoy changes in the sound and quality of upstream such as audio players and music sources.Aluminum faceplateIn the development of Maestraudio's IEM, the characteristics of the various components that make up the IEM are important parameters.In particular, the selection of housing components is analyzed in detail using the FEM (finite element method).The sound emitted from the back of the dynamic driver directly hits the rear faceplate and causes small vibrations.We focused on the fact that by transmitting this vibration to the entire housing more quickly, it is possible to obtain a sound with a large amount of information.Therefore, the MA910SR uses an aluminum faceplate with a hairline in the faceplate part of the housing.As a result, compared to resin faceplates, the MA910SR has an overwhelmingly larger amount of sound information transmitted from the faceplate to the inside of the housing.As a result, the MA910SR succeeded in achieving a higher resolution sound with more information while maintaining the spaciousness of the soundstage.Realization of a compact, lightweight, and wide soundstageThe MA910S series is equipped with a single graphene-coated dynamic driver developed and tuned exclusively for Maestraudio brand products.In tuning, we focused on the head transfer function and optimized the frequency characteristics suitable for the listener to feel a sense of realism.By combining the passive ceramic coat tweeter, which will be described later, it realizes natural reproduction with as little distortion as possible from low to high frequencies.At the same time, by installing HDSS*, a high-performance sound correction device, we have acquired a wide soundstage that was difficult to achieve with a small resin housing.The MA910S series is a universal IEM that produces a pleasant listening-type sound regardless of genre, while also being suitable for spatial perception and expression such as e-sports and watching movies.*HDSS is a patented technology of TBI Audio Systems LLC.Ceramic sound technology using piezoelectric ceramics cultivated by the passive ceramic coat tweeter "RST" Maestraudio,which was born from a new idea.The MA910S series is equipped with the Reactive Sympathetic Tweeter (RST), a passive ceramic coated tweeter developed based on a new concept.The Vertical Support Tweeter (VST), a multilayer piezoelectric ceramic tweeter, which can be said to be the core technology in ceramic audio technology, requires coaxialization of the unit because treble sounds above 20 kHz have extremely high straightness.In the development of the MA910S series, a ceramic tweeter was required to efficiently transmit treble sound forward even if it is disconnected from the coaxial for use in universal IEM type housings.This is where "RST" was born, which has split vibrations like cymbals and music boxes.The principle is to irradiate the diaphragm with sound waves from the dynamic driver to induce vibrations.This product uses a diaphragm based on red copper, which is often used in wind instruments, and a unique special ceramic coating is applied to its surface to obtain a high-pitched sound with even better grain.This is a passive ceramic coat tweeter with a new concept that allows you to control the sound quality according to the dimensions, material, and support method of the diaphragm.The hybrid cable and the original earpiececable use a silver-coated OFC and OFC hybrid cable to improve sound separation and provide excellent localization.The Pentaconn ear is used for the connector and a "protrusion on the right connector side" is attached to make it easy to distinguish left and right even in the dark.In addition, the earpiece comes standard with the original earpiece "iSep01" which realizes an excellent fitting with little burden even when used for a long time by slightly reducing the softness of the silicone rubber.In addition, it is a full range of accessories such as genuine leather cord reel and carrying pouch.Maestraudio, which is providedwith high quality in Japan, is particular about making all products Japan, and incorporates the "craftsmanship" of Japan at a high quality level, such as molding technology by master craftsmen in Gunma and surface treatment by Tsubame Sanjo Manufacturing.All Japan assembled in Japan and provided with high quality.● Shape: IEM type● Driver/ Hybrid type/ 10mm
