Maestraudio MA910SR Maestro Blue with 10mm Dynamic Passive Tweeter with RST Made in Aluminum Pentaconn ear Compatible for [Earphones Graphene-Coated

We offer a wide variety of products, and the following precautions apply to some of them. Please note that they are listed for all products. 【Voltage Compatibility】Designed for Japanese voltage (90-110V). Using with a different voltage may cause malfunction. 【Plug Type】Japanese plugs (A or B type). Use a conversion adapter if needed. 【Transformers & Adapters】Transformers adjust voltage; adapters only change plug shape. Using an adapter without a transformer may damage the product. 【Liability】We are not responsible for damages caused by improper use, such as using the product without a transformer. ■ Supports detachable cables using Pentaconn ear connectors. To minimize sound quality degradation, the detachable cable uses Pentaconn ear connectors, which are renowned for their low contact resistance. Not only is the mechanical reliability during attachment and detachment stable, but the contact resistance can be reduced to less than 1/10 compared to MMCX, a common detachable cable connector. ■ Aluminum faceplate adopted. The selection of components for the enclosure was meticulously analyzed using our own FEM (Finite Element Method). The faceplate of the enclosure uses an "aluminum faceplate" with a hairline finish. As a result, the amount of sound information transmitted from the faceplate to the inside of the enclosure is overwhelmingly greater compared to a resin faceplate, achieving improved resolution while maintaining a wide soundstage. ■A universal IEM designed for compactness, light weight, and a wide soundstage. Equipped with a newly developed graphene-coated dynamic driver. Focusing on the head transfer function, it optimizes the frequency response to provide listeners with a sense of realism. It achieves natural reproduction with minimal distortion from low to high frequencies. At the same time, by incorporating the high-performance acoustic correction device HDSS, it achieves a wide soundstage that was difficult to realize with a small resin housing. ■ Equipped with the "RST" passive ceramic-coated tweeter, born from a new concept. This ceramic tweeter, developed for use in universal IEM-type housings, efficiently transmits high frequencies forward even when off-axis. Sound waves from the dynamic driver are directed onto the diaphragm to induce vibration. The diaphragm uses red copper, which is commonly used in wind instruments, as its base material, and a unique special ceramic coating is applied to its surface to obtain even more detailed high frequencies. ●Shape: Universal IEM type (over-ear wear) ●Driver: Hybrid type: 1 x 10mm diameter graphene-coated dynamic driver, 1 x 9mm diameter RST (Reactive Sympathetic Tweeter) ●Impedance: 16Ω ●Sensitivity: 100dB ●Frequency response: 20Hz～40KHz ●Cable length: 1.2m (3.5mm 3-pole L-shaped plug) ●Cable: Silver-coated OFC + OFC hybrid cable ●Connector: Pentaconn ear ●Accessories: iSep01 eartips (S/MS/M/L), genuine leather cord reel, carrying pouch ●Country of origin: Japan
