[High-Functionality Idea Product that Meets the Needs of Musicians]
Best Brass is a Japanese company that develops and sells accessories for brass instruments. Their mutes, developed especially for musicians who struggle with practice spaces, are highly regarded not only in Japan but worldwide. These digital mutes not only mute sound but also incorporate elements necessary for practice, and their innovative design envelops woodwind instruments, which inherently leak sound due to their structure, to mute them.

[Ver3, Developed Through Extensive Research by the Inventor of Practice Mutes]
The e-Brass III is a mute with an integrated electronic module. It is the third generation of the e-Brass, developed through continued research on mutes by Shinji Hamanaga, the inventor of the Silent Brass and founder of Best Brass. By attaching it inside the bell and connecting it to headphones, you can play while listening to your own sound. Its surprisingly light and compact design, combined with a natural playing feel and stable intonation, delivers excellent muting performance, allowing you to practice without worrying about disturbing others.

[Comfortable Playing Feel Achieved Through Analog Muting and Compact Design]
The e-Brass boasts high sound-deadening performance and a natural playing feel. It employs an extremely analog muting method, achieving both high quietness and a natural playing feel close to that of an open instrument. Even when playing normally, the sound leakage to the outside is reduced to the level of quiet conversation. While the sound is not completely eliminated, it is perfect for practicing at home. Connecting headphones allows you to play at the volume your body intends, even while muting the sound.
