Electret Stereo Hi-Fi Microphone N8404 Set

This is a vintage Hi-Fi Stereo Electret Microphone System, model N8404, likely dating from the 1970s or early 1980s. The set is presented in its original cardboard box which features a brown exterior and an orange flocked interior tray molded to hold the components securely. The kit includes two cylindrical condenser microphones with black matte finishes and polished chrome or silver-toned tops. The microphones are connected by integrated grey cabling to a central battery or control module. The module is labeled 'HI-FI STEREO ELECTRET MICROPHONE SYSTEM' in a white sans-serif font. Also included are two plastic swivel mounting brackets. The microphones appear to be constructed from a combination of metal and high-impact plastic. Notable features include the stereo configuration designed for wide-field audio pickup, a common consumer-grade audio high-fidelity accessory of its era. The condition appears to be excellent, categorized as 'New Old Stock' or lightly used, with no visible corrosion in the battery compartment or fraying of the wires. The packaging shows minor shelf wear on the edges but maintains vibrant graphics and clear text. This system represents the transition of audio recording technology into the consumer hobbyist market during the late 20th century.
