● We do not accept any complaints about odors. Please purchase only if you understand this. I have had chronic rhinitis for 40 years and cannot smell anything. I cannot accurately describe whether the items for sale have an odor or not, so I have decided not to mention it. ● I have confirmed the output from both the left and right channels. For details, please see here → http://www.smci.jp/s/headp/page/cd900st?ima=2643 And also, for reference → https://www.sony.jp/headphone/products/MDR-CD900ST/?srsltid=AfmBOoqB7Kp0tIyVjyOWvtjAvegrDDnNGFDLAdBFOr3DGa4pHIJAVGz7 ● Regarding the appearance, there are no major scratches or chips, but there is a feeling of use. The ear pads were starting to show wear, so I have replaced them with new compatible ones. Well, as for the appearance, it is based on my personal subjective opinion, and there may be other scratches that I have not noticed, so ultimately, please refer to the images and make your own judgment. Thank you for viewing.
