This is a head device-style headphone from Jikka Net Tanaka, styled after the one from the game "Ayase". It was a bonus item included with the "Persona 3 The Movie" Blu-ray. The cable and box are not included. I used it a few times, and music could be played when using a commercially available plug. The synthetic leather is peeling due to aging. There are also cracks in the plastic parts. Therefore, it is a junk item.
