{"type":"firestarter.listing","listing":{"id":"lst_TZfIcBRB","product_name":"TRN TA3","category":"Earphones/IEMs","description":"\n\n\n\nA union between rigidity and pliability Results in an amazing sound performance\nTRN's first dual dynamic driver equipped with Knowles balance armature. Our acoustics engineers tuned the TA3 in accordance with the characteristics of both dynamic drivers and balance armature, so that these two types of drivers complement each other. The ultra-wide frequency response of the two dynamic drivers and the excellent resolution of the balance armature are brought together to create exhilarating music experiences.\n\n\n\n\n\nDual dynamic drivers + Knowles balance armature 3-way hybrid configuration\nTRN TA3 comes equipped with 10mm beryllium-coated dual-magnetic dynamic driver responsible for low frequency. A 6mm titanium-coated dynamic driver for mid range and upper-mid range frequency. Knowles 33518 balance armature for treble. Complimented by an advanced, custom-tuned frequency crossover network, TA3 is able achieve deep punchy bass, clear vocals and exceptional resolution without harshness\n\n\n\n\n\n\nCombining Zinc alloy and resin to create an elegant aesthetic appearance\nThe Zinc alloy faceplate utilizes five-axis CNC machining to ensure high precision operation and better surface finishing. The ergonomics housing cast with imported semi-transparent resin. Together, they give an exquisite and luxurious sonic presentation\n\n\n\n\n\nElectronic + Passive dampener sound tuning methodology Truly restore the high-fidelity sound\nTRN TA3 adopts conventional electronic crossover and passive sound dampeners to accurately and evenly distribute the bass, mid-range and treble regions. The implementation of both dual dynamic drivers and balance armature helps achieve coherency throughout the entire frequency spectrum.\n\n\n\n\n\n4 Core Silver-Plated Copper Wires\nTA3 adopts 4 core silver-plated copper wounded and oxygen-free copper braided cable. Such configuration has the advantages of both silver-plated copper and oxygen-free copper. It effectively gives fullness to the sound. Resolution is greatly enh","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1-2_b913ab5f-248e-4619-87ed-9b3a7e775927.jpg?v=1677481555","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_7467c6e9-eb65-46b8-9f24-a9642c5a67d4.jpg?v=1677481520","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1-3_602412f3-756e-48ca-b28f-f5f115b17f3c.jpg?v=1677481520","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/6_bb65c5e6-f0a3-43da-914b-1eaa5ee79d80.jpg?v=1677481520","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/7_5afda6cb-43ac-47c3-b72c-fdac70f14040.jpg?v=1677481520","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_748fca75-6fa4-4032-a004-f33475294e6b.jpg?v=1677481480","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/2_c2fa5bde-626b-44a6-a4cd-fb1fb47638ea.jpg?v=1677481480","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/3_162266f2-bbb4-4c7d-b674-6c188b8da98b.jpg?v=1677481480","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/4_dd5e1984-7109-4ef9-afd0-89e56d748637.jpg?v=1677481480","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/5_3c71f6ec-9726-4f1d-b804-2be1fe4b838d.jpg?v=1677481481"],"price":58,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.052Z"},"share_url":"https://firestarter.network/l/lst_TZfIcBRB","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
