Maestraudio / OTAMA910SBLU

Variations

Maestraudio / MA910S is an in-ear earphone that is equipped with a newly developed graphene-coated dynamic driver, a new passive tweeter ""RST"" (Reactive Sympathetic Tweeter) created by ceramic audio technology, and a high-performance acoustic correction device ""HDSS"" from TBI Audio Systems LLC.

■Universal IEM aimed at small size, light weight, and wide sound stage
・The ``MA910S'', the first product of the Maestraudio brand, is equipped with a single newly developed graphene coat dynamic driver developed and tuned exclusively for the brand's products. When tuning, we focused on the head-related transfer function and optimized the frequency response to give the listener a sense of realism. By combining it with a passive ceramic coated tweeter (described later), we are able to achieve natural reproduction with minimal distortion from low to high frequencies. Additionally, by incorporating HDSS (*), a high-performance acoustic correction device, we have achieved a wide sound stage that was difficult to achieve with a small resin casing.
The MA910S is a universal IEM that produces comfortable listening-type sounds regardless of genre, while also being suitable for spatial perception/expression such as e-sports and movie watching.
*HDSS is a patented technology of TBI Audio Systems LLC.

■ Passive ceramic coated tweeter ""RST"" born from a new idea
・Ceramic sound technology using piezoelectric ceramics cultivated by the Maestraudio brand. MA910S is equipped with ""RST"" (Reactive Sympathetic Tweeter), a passive ceramic coated tweeter developed based on a new idea. The multilayer piezoelectric ceramic tweeter ""VST"" (Vertical Support Tweeter), which can be said to be the core technology in ceramic audio technology, has a very high straightness of high frequencies over 20kHz, so it was necessary to make the unit coaxial. In developing the MA910S, we needed a ceramic tweeter that would efficiently transmit high frequencies to the front even if it was off-axis for use in a universal IEM type housing. This led to the creation of ""RST,"" which has split vibrations similar to cymbals and music boxes. Its principle is to induce vibration by irradiating the diaphragm with sound waves from a dynamic driver. This product uses a diaphragm made from shakudo, which is often used in wind instruments, and has a unique special ceramic coating applied to its surface to obtain a clearer high-pitched tone. This is a passive ceramic coated tweeter with a new concept that allows you to control the sound quality by changing the dimensions, material, and support method of the diaphragm.

■Hybrid cable and original earpiece
・The MA910S cable uses a hybrid cable of silver-coated OFC and OFC, achieving improved sound separation and excellent localization. In addition, the original earpiece ""iSep01"", which achieves excellent fitting and sound insulation by slightly reducing the softness of silicone rubber, is included as standard in 4 sizes (S/MS/M/L). Also included are ear hooks, a genuine leather cord reel, and a carrying pouch.

■Domestic assembly providing high quality
・MA910S is all assembled in Japan and is provided with high quality.
