This is a JH Audio JH10X3 PRO Universal Limited. I used it a few times after purchasing it, but I'm selling it because I bought other earphones and stopped using it. This model was sold only in Japan and in limited quantities, making it a rare and valuable pair of earphones. With 3BA drivers (1 for low frequencies, 1 for mid frequencies, and 1 for high frequencies), the overall sound connection is good, and I think you can feel a natural sound range. There are no scratches or discoloration on the main unit, and the sound quality is also fine, but this is a subjective assessment, so please refrain from purchasing if you are extremely concerned about the condition or are very sensitive. Also, please note that the box is torn. There are no pets or smoking in the environment. Please check my profile before purchasing. Also, please understand that I do not offer any warranty after purchase.
