Early model handheld satellite XM radio receiver.  Needs a subscription and earphones.  Comes with base and power supply, and antenna on a long lead.  Batteries are old  and would need replacing if it wasn’t on the plug-in base… (It was used in my office when I was working…)

$20 to ship.  As is, and you would have to find out if you can still use it with the Sirrius/XM system still before you bought it…
