With a 4.9 mm bore that fits most IEMs—including models from AKG, Audio-Technica, JVC, and more—these tips seal out noise, reduce fatigue, and stay comfortable through daily wear. Washable and reusable, they’re built for real-world use.\nComfortable foam that lasts\nDekoni’s slow-rebound memory foam contours to your ear canal without collapsing, maintaining its shape even after long hours. Built for daily use, it delivers consistent comfort. Plus, they’re washable with cold soap and water and dry quickly with a paper towel or air-dry. \nUniversal compatibility\nThe 4.9 mm inner bore matches the most common IEM nozzles, so these tips fit gear from AKG, Audio-Technica, Jaybird, Beyerdynamic, Beats, Denon, JVC, Monster, and other. One set covers virtually anything you already own.\nEffective passive isolation\nMemory foam creates a snug seal that reduces ambient noise. Rather than exaggerating bass, this isolation clarifies midrange and high frequencies so you hear more detail in your music.\nDurable and reusable\nThe high-density foam resists compression over time, and when it gets dirty, a cold-soapy wash is all it takes to restore it.\nProduct highlights\n\nCompatible with IEMs using standard 4.9 mm bores\n\nSlow-rebound memory foam for lasting comfort\n\nWashable and reusable—cold soap and water recommended\n\nThree pairs per pack (Small, Medium, Large options)\n\nOuter diameters: 11.2 mm (S), 13 mm (M), 14 mm (L)\n\nBore: 4.9 mm; height: 10.6 mm\n\n\nSpecs\n\nColor: Black\n\nTube opening: 4.9 mm inner bore\n\nHeight: 10.6 mm\n\nOuter diameter: 11.2 mm (S), 13 mm (M), 14 mm (L)\n\n\nWhat’s included\n\n3 pairs of Mercury memory foam tips (same size per pack)\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634377.png?v=1751070400","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634389.jpg?v=1751070535","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634386.jpg?v=1751070526","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634376.png?v=1751070179","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634383.png?v=1751070418","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634384.png?v=1751070520","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634379.png?v=1751070405","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634392.jpg?v=1751070763","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634385.jpg?v=1751070525","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634390.jpg?v=1751070537","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634391.jpg?v=1751070760","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634387.jpg?v=1751070528","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634375.png?v=1751070177","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634381.png?v=1751070412","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634382.png?v=1751070415","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634374.png?v=1751070173","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634378.png?v=1751070402","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634380.png?v=1751070410","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-dekoni-dekoni-audio-etz-mercury-premium-memory-foam-isolation-earphone-tips-mercury-4-9mm-1175634388.png?v=1751070532"],"price":24.99,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.479Z"},"share_url":"https://firestarter.network/l/lst_m0bD0zOU","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
