The TOA WH-4000A is a unidirectional electret condenser headset microphone developed specifically for aerobics instructors, fitness coaches, and gym presenters who need reliable hands-free audio in high-movement, high-perspiration environments. Its cardioid pickup pattern focuses on the speaker while rejecting ambient noise, making it effective in reverberant gym and studio spaces where off-axis sound rejection matters.

Designed as a sports-optimized variant of the WH-4000H, the WH-4000A features moisture ingress protection and an adjustable headband with dual ear hooks to maintain position during dynamic instruction. It connects directly to the TOA WM-5325 wireless transmitter and the WM-D5300 digital wireless transmitter via a 3.5 mm monaural plug, drawing power from the transmitter with no separate battery required. For fitness facilities and houses of worship running TOA 5000 Series wireless systems, this mic fills a specific niche that general-purpose headsets do not address.
