Maestraudio MA910SR Pentaconn ear connector

■Compatible with re-cable using Pentaconn ear connector. In order to minimize sound quality deterioration, the Pentaconn ear connector, which has a reputation for low contact resistance, is used as the re-cable connector. Not only is the mechanical reliability stable when connecting and disconnecting, but the contact resistance can be suppressed to less than 1/10 compared to MMCX, a common re-cable connector.

■Uses an aluminum face plate. The selection of the components of the housing was carefully analyzed using our own FEM (finite element method). The faceplate part of the casing uses an “aluminum faceplate” with a hairline. As a result, compared to a resin faceplate, the amount of sound information transmitted from the faceplate to the inside of the housing is overwhelmingly larger, achieving improved resolution while maintaining the width of the sound stage

■Universal IEM aimed at small size, light weight, and wide sound stage. Equipped with a newly developed graphene coat dynamic driver. Focusing on the head-related transfer function, we optimized the frequency characteristics suitable for listeners to feel a sense of presence. Realizes natural reproduction with minimal distortion from low to high frequencies. At the same time, by installing HDSS, a high-performance acoustic correction device, a wide sound stage has been achieved, which was difficult to achieve with a small resin housing.
