The Surefire EP4 Sonic Defender Plus earplugs are designed to protect your hearing while maintaining a low-profile fit that sits flush against your ear, making them highly effective for use under a tight motorcycle helmet.\u003c\/p\u003e\n\u003cp\u003eThe EP4 features a triple-flanged stem made from soft, hypoallergenic medical-grade polymer, providing a secure seal for maximum noise reduction. The \"Plus\" designation indicates the inclusion of integrated filter caps. When the caps are left open, the acoustic filter allows safe ambient sounds—like sirens, traffic, and in-helmet comms—to pass through while blocking harmful noise spikes. When closed, the earplugs deliver a Noise Reduction Rating (NRR) of 24 dB for maximum protection during high-speed highway touring or track days.\u003c\/p\u003e\n\u003ch4\u003eFeatures:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eFilter Caps:\u003c\/b\u003e Integrated attached caps allow you to switch between situational awareness (caps open) and maximum noise isolation (caps closed) without removing the earplugs.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eEarLock Retention Rings:\u003c\/b\u003e Patented retention rings lock the earplugs securely into the concha bowl of your ear, preventing them from dislodging when pulling a helmet on or off.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eTriple-Flanged Stem:\u003c\/b\u003e Provides a deep, secure seal specifically suited for standard to larger-sized ear canals.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eLow-Profile Design:\u003c\/b\u003e Sits flush within the outer ear, preventing uncomfortable pressure points against the helmet liner.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHypoallergenic Material:\u003c\/b\u003e Manufactured from a medical-grade polymer that is soft, durable, and resistant to sweat and earwax for long-lasting comfort.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eWhat's in the Box:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e1x Pair of Surefire EP4 Sonic Defender Plus Earplugs (Black \/ Medium)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Detachable Polymer Lanyard\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Hard Plastic Carrying Case\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment Notes:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSizing:\u003c\/b\u003e This specific part number features the \"Medium\" EarLock ring, which fits the concha bowl of 85% of adult users.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eStem Design:\u003c\/b\u003e The EP4 utilizes a triple-flanged stem. \u003ci\u003e(If you have smaller ear canals, the double-flanged Surefire EP3 may provide a better fit).\u003c\/i\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ci\u003e\u003c\/i\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e EP4 earpiece will not provide hearing protection if the noise-reducing filter is removed from the ear plug assembly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 style=\"white-space: pre-wrap; text-align: center;\"\u003e\n\u003cbr\u003eExplore all Ear Protection options available\u003cbr\u003eat TMBR MOTO: \u003ca title=\"Shop for motorcycle earplugs at TMBR MOTO.\" href=\"https:\/\/www.tmbrmoto.com\/collections\/earplugs\"\u003e\u003cspan style=\"color: rgb(215, 65, 35);\"\u003e\u003cstrong style=\"color: rgb(215, 65, 35);\"\u003eCLICK HERE\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\n\u003c\/h4\u003e\n\u003cp class=\"\" style=\"white-space: pre-wrap;\"\u003e\u003cbr\u003e\u003ca href=\"mailto:info@upshiftonline.com\" target=\"\"\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/a\u003e\u003cmeta charset=\"utf-8\"\u003e\u003ca href=\"mailto:info@upshiftonline.com\" target=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0578\/8722\/8063\/files\/MADE_IN_USA_BAND_568_2048x2048.jpg?v=1658167811\" style=\"float: none;\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp class=\"\" style=\"white-space: pre-wrap;\"\u003e\u003cbr\u003ePart Number: EP4-BK-MPR\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0622\/5720\/1317\/files\/EAR_BANNER.jpg?v=1783966520\" alt=\"\"\u003e\u003c\/p\u003e","brand":"Surefire","offers":[{"title":"Default Title","offer_id":42610530451621,"sku":"SURE-FIRE-SNC-DEF-MED","price":21.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0622\/5720\/1317\/products\/SureFire_EP4_Sonic_Defender_Plus_Ear_Plugs.jpg?v=1787158038","url":"https:\/\/www.tmbrmoto.com\/products\/surefire-ep4-sonic-defender-plus-earplugs-black-medium-ep4-bk-mpr","provider":"TMBR MOTO","version":"1.0","type":"link"}
