The product will plug into the 1/4" jack socket of a musical instrument or audio equipment and transmit wirelessly to an FM receiver headphones. The emission frequency must not drift. See attachment for example similar to requirement. (note that no power indicator LED is required). There must be virtually no delay - bluetooth solutions already rejected. A milestone payment of 20% will be paid on delivery of one functioning PCB for customer testing before remaining PCBs supplied.
