This item shows signs of use, but I believe it's in relatively good condition. There were no issues with the sound quality. These are professional-grade headphones used for monitoring in DJing, recording, and more. I think this is a very user-friendly item for both primary and secondary use. These headphones are designed for monitoring, with a three-dimensional sound and excellent original sound fidelity. The clamping force is a bit strong, but the weight is light, so the fit is good, and the sound isolation is also good. ● Weight: Approximately 220g ● Single-sided cable ● Foldable Please refrain from purchasing if you are concerned as this is a used item. The box and instruction manual are not included. ------------------------------------------------ ＜Features＞ ■ Professional monitor headphones that meet the demands of studio engineers and professional DJs working on-site. ■ High original sound reproduction and balanced, flat sound quality from low to high frequencies, faithfully reproducing the original sound. ■ High sound isolation that is not affected by surrounding sounds even in a high-volume environment. ■ Thick, soft ear pads for comfortable wearing even during long hours of work.
