KIMAFUN KM-G100-1 Wireless Headset Microphone

The KIMAFUN KM-G100-1 is a 2.4 GHz wireless headset microphone designed for fitness instructors and active users who need hands-free voice capture. Its waterproof and sweatproof construction protects the condenser element and headset frame during high-intensity movement. The package includes a 3.5 mm phone adapter and a 6.35 mm adapter for connection to amplifiers, mixers or outdoor speakers. A USB sound card is required for laptop or computer use.

Sustained load behaviour

The microphone delivers a sensitivity of 120 decibels and a signal-to-noise ratio of 80 decibels, maintaining clear voice reproduction throughout extended sessions. The 2.4 GHz link establishes automatically within two seconds and resists environmental interference during continuous operation. Waterproof materials on the gooseneck and wireframe prevent moisture ingress that could degrade audio quality over time. The system is built to endure repeated high-impact use without fatigue.

Installation and common issues

Connection is plug-and-play once the correct adapter is fitted to the receiver; no driver installation is needed. The most frequent setup problem is insufficient charging current — using a laptop USB port often fails to charge the transmitter and receiver fully, so a 5 V, 1 A to 2 A charger is required. Remember to power off both units when not in use to preserve battery health. A USB sound card must be sourced separately for computer input.
