Designed to integrate with hard hat systems, these protective headphones enable clear communication for crew members working in proximity to heavy machinery, power distribution equipment, or high-SPL concert venues.\u003c\/p\u003e\u003cp\u003eThe dual over-the-ear speaker configuration provides passive isolation that allows engineers and technicians to monitor assistive listening feeds without removing hearing protection. With a frequency response optimized for speech intelligibility rather than music reproduction, the LA-409 ensures that safety announcements, cue systems, and intercom feeds remain intelligible even when background noise would otherwise mask critical communication.\u003c\/p\u003e\u003cp\u003eThe 99 cm cable with 3.5 mm TRS connector allows direct connection to ListenTALK receivers and other assistive listening systems commonly deployed in stadiums, convention centers, and industrial training facilities. Rugged construction withstands the demands of daily use in harsh environments where standard consumer headphones would fail.\u003c\/p\u003e","brand":"Listen Technologies Corporatio","offers":[{"title":"Default Title","offer_id":52449774076088,"sku":"117327","price":154.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/117327_LISTEN-LA-409_ALT01sqr.jpg?v=1783615630","url":"https:\/\/soundpro.com\/products\/listen-technologies-la-409","provider":"SoundPro","version":"1.0","type":"link"}
