This is a collaboration model between the tactical music unit (Walküre) and the Hi-Res compatible headphones Pioneer SE-MX8! The housing features the logo of Macross Δ's tactical music unit "Walküre." An original carrying pouch is included. Used a few times. Due to aging, the main unit was sticky, so I wiped it off, and the "R" marking came off a little. Also, the ear pads are tattered due to aging, but you can use them like new by replacing them. Please purchase only if you understand that this is stored and inspected by an amateur. ( . .)" The poster that came with the purchase was opened for the first time to take photos this time, so I don't think there is any sun damage. Playback confirmed (I played Walküre's songs on iPhone and MacBook, and there were no problems with the sound) The SE-MX8 is a Hi-Res compatible headphone that can reproduce a wide range of 5Hz to 40kHz. In addition to its unique 40mm driver, it is equipped with a chamber (air chamber) to reproduce rich bass and high-quality sound. This is a valuable headphone that is hard to come by these days, so please consider purchasing it if you are a collector or if you want to use it by replacing parts!
