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 this one. This model was sold exclusively in Japan and in limited quantities, making it a rare find. 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 a perfectionist. 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.
