The creation inspiration of Azrael comes from the archangel Azrael, known as the "Angel of Death" in Genesis, who is also called the "Angel of Death". In ancient literature and art, Azrael is often depicted as an angel with a sword in his left hand, holding the Book of Life in his right hand and wearing a black hood, to record the beginning and end of every life. Eletech incorporates the gentle, solemn yet kind characteristics of the "Angel of Death" itself into Azrael.

As a new generation of works in the Virtues series, Azrael (Dark Angel) not only inherits the high analytical power and warm natural sound characteristics of the previous generation Fortitude, but also improves the ultra-high purity single crystal copper conductor structure with a new wire diameter of 25.5AWG. Single crystal copper wire contains less impurities and oxygen than ordinary copper wire, and can better transmit signals, making the sound image more distinct and the level of detail richer.
