◯ This is an auction for the Audio-Technica ATH-R70x headphones. The device itself powers on and plays audio well. There are no noticeable scratches or stains upon visual inspection, but since it has been stored by a non-professional, I am listing it as "slightly scratched or stained." Please understand. ◯ The sound quality is clear as advertised, and I believe it's fair to call it a "masterpiece of monitor headphones." I felt that it particularly shines with balanced connections. It was once my reference headphones, but I am selling it as part of decluttering. For more details, please search for reviews of the "ATH-R70x" on Kakaku.com, etc. ◯ In addition to the main unit, the outer box, the cord (1.8m / φ3.5mm gold-plated stereo mini plug), the φ6.3mm gold-plated stereo conversion plug adapter, and the pouch are all included. As a bonus, I will include a balanced cable (4.4mm, 2m long) purchased from Amazon. ◯ The headphone stand is not included. ◯ When purchasing, please understand that this is a used item stored by a non-professional, and please refrain from returns or claims.
