Thank you for viewing. This is the t3-01, a popular wooden-grained headphone from Tago Studio. I purchased it in 2022 and have been using it with the SONY wm1z, which is also currently listed. I used it quite a bit when I first bought it, but in the last 1-2 years, I've only used it for about an hour a month. I estimate that I've used it for about 100 hours, so I think you can still enjoy the aging process. I believe all the accessories are included (cosmetic box, dedicated carrying case, warranty documents, 3.5mm unbalanced cable, 6.6mm jack). As a bonus, I'll also include the genuine 4.4mm balanced cable, a 4.4 balanced to 3.5 unbalanced output conversion jack that I purchased for around 5000 yen, and two headphone stands: a Sanwa Supply headphone stand and a clamp-type headphone holder. It seems that the straight-type jack for the balanced cable is currently discontinued. I haven't used it much, and I've handled it with care, so I think it's in good condition. Also, the serial number is a lucky "5555," which is a nice little bonus. As this is a high-value item, I will pack it carefully and ship it. Thank you for your consideration. The list price is below for your reference. t3-01 ¥69300 T3-01 Headphone Cable φ4.4mm 5-pole plug Balanced T3-CB41 ¥16500 Balanced to Unbalanced Converter 5000 Headphone holder, stand About 3000 yen?
