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.\u003c\/p\u003e\u003cp\u003eDesigned 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.\u003c\/p\u003e","brand":"TOA ELECTRONICS, INC","offers":[{"title":"Default Title","offer_id":52446693458104,"sku":"67097","price":82.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/67097_TOA-WH-4000A-UHF-Wireless-Aerobics-Headset-Microphone_ALT01sqr.jpg?v=1789137096","url":"https:\/\/soundpro.com\/products\/toa-wh-4000a","provider":"SoundPro","version":"1.0","type":"link"}
