This is a lot of 4 Elegiant plug and play desktop computer microphones, model EGM-03.  They are connected to your computer by a wired USB cable.  They have a flexible goose neck and an anti-slip stable base.  It doesn't look like any of them have ever been taken out or used before, so they're in good shape.  The boxes have a little wear to them here and there, but it's nothing major.  Thanks for looking!
