Worked perfectly to extend a Logitech Harmony IR blaster.
Used as a Mono cable to extend 2.5mm microphone for security system or 2-way radio. Please note, this is a Mono cable not Stero cable, the connector is 2.5mm instead of 3.5mm
Wored as an extension for the charging Cable for some wireless headphones like jbl Synchros E30 E40 E40BT E50BT J56BT S300 S300I S300a S500 S700 S400BT,AKG headphones and Harman Kardon BT Premium headphones
