No box or instruction manual. Operation confirmed and initialized. I planned to use this a few times for testing audio equipment, but I ended up using something else, so this is an unused item. I removed the insulation sheet and powered it on only once to confirm operation. This is a full-fledged heavy bass model, and it's rare to find one this light. It's a good product that doesn't cause fatigue when worn. No noise cancellation. Accessories: Type-C cable JVC Kenwood official page: https://www.jvc.com/jp/headphone/lineup/ha-xc62t/
