This is one of my collection of minidisc player, recorders.  The MZ-N510 player, recorder looks very nice.  There are very few signs of wear or use.  Excellent.  This has been tested and works as it should.  No issues. 

I'm also including a few nice items that would cost a lot if purchased separately: 

Sony headphones, look unused

AC power adapter

Arm band holder for minidisc player, cool, green!

Line in optical cord

AA battery

6 minidiscs, 3 new in wrapping, 3 have good music on them
