is there any solution for my concern.
my iball pulse BT4 bluetooth headphone is not working with dell vostro 1540
Have you tested other BT (bluetooth) devices on the Vostro 1540? What BT device is installed in the Vostro 1540? What operating system are you running? You should check with iball- Chat for support and setup of their product. Assuming you read through its User Manual for troubleshooting steps.
