Nice vintage small speakers made for Radio Shack. These are Optimus model AMX 10. Speakers are powered by electric cord or total of 8 C batteries. Power cord included. Battery compartment appears clean. Overall in good used condition. Everything works fine. The plug/jack works fine in for example your smartphone. I would usually use, to plug in my phone and listen to satellite radio. No original box only partial packaging bottom. Selling speakers,power cord and attached jack cord as is. Please see pictures for overall condition. All sales are final. No returns accepted. No refunds. Thanks.
