This is a Final Sonorous III, kept at home. I own several types of headphones, and since I mainly used another pair, the usage time was about 1 hour per month on average. I used them in a non-smoking, pet-free environment. I tested the sound before listing, and there were no problems. I believe the condition is relatively good, with few cracks in the headband and ear pads. Please refer to the photos for details and make your purchase decision. The items included are the outer box, cable, and the main unit. (Everything in the photos is included.) These headphones are relatively monitor-oriented, with beautiful mid-high frequencies, and I think they are particularly suitable for listening to female vocals and songs with few instruments. Please note that this item is also listed on other flea market sites, so it may be sold out.
