{"product_id":"er15b","title":"ER15B Solid Plug\/Attenuator","description":"\u003cp\u003eSolid Replacement Filter for Musicians Earplugs High-Fidelity Hearing Protection replacement filters\u003c\/p\u003e\n\u003cp\u003eSolid buttons are available for use with Musicians Earplugs. Some earmold labs offer a solid molded button, while others seal the diaphragm of a standard button with epoxy. When the sound channel of the earmold is plugged using a solid or sealed button, the total attenuation is dependent on the button plus the earmold seal. Etymotic's sealed-diaphragm button provides approximately 30 dB attenuation (5 dB more than the ER-25) based on measures performed at E-A-R Cal Laboratories, Indianapolis, IN, using the ANSI standard Real Ear Attenuation at Threshold (REAT) method. A solid earmold provides greater attenuation than a Musicians Earplug with a sealed or solid button in the sound channel.\u003c\/p\u003e","brand":"Etymotic","offers":[{"title":"Default Title","offer_id":49684618674314,"sku":"ER15B","price":5.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/4144\/8586\/files\/product_e_r_er15b_450.jpg?v=1783406419","url":"https:\/\/etymotic.com\/products\/er15b","provider":"Etymotic","version":"1.0","type":"link"}
