SILVERSONIC SN-3000 wired headphones with an over-ear design. - Brand: SILVERSONIC - Model: SN-3000 - Type: Wired headphones - Design: Over-ear - Accessories: Original box Thank you for viewing. These are retro headphones from the Showa to early Heisei era, owned by my grandfather. They haven't been used much, so they are relatively clean, but they are old due to the long storage period. Please check the photos for the condition. Also, I haven't been able to confirm the operation as I don't have the means to do so. Please consider these as junk items, suitable for those who can maintain them themselves, or for use as antiques or collectibles. bedphone Showa Retro Showa Retro Vintage Vintage Modern Retro goods
