Whether you're a music lover or a professional audio engineer, the KZ PR2 earphone delivers the performance and comfort you need to enjoy your music to the fullest.\n\n\nNewly Developed 13.2mm Real Planar Unit\nKZ PR2 is equipped with a newly developed 13.2mm real planar unit which brings faster response speed and better high-frequency performance. It replaces the voice coil structure with ultra-low resistance nano-silver electroplating lines.\n\n\n7+7 N52 Rubidium Magnet Array\nKZ PR2 is equipped with a double-sided array magnetic circuit system composed of 14 N52 rubidium magnets, which brings the magnetic circuit performance to an ideal level, has a stronger transient response, and brings exquisite and vivid on-site sound quality.\n\n\nHigh-Precision Nanoscale Silver-plated Diaphragm\nKZ PR2 has adopted a silver-plated nanoscale diaphragm which provides a great sound quality. Its circuit is plated on the diaphragm using a silver-plated process. The accuracy of the circuit needs to be controlled within 2 microns, resulting in higher technical requirements.\n\n\nExquisite Design and Craftsmanship\nAlloy one-piece die-cast front housing, made of high-density alloy material, has a delicate appearance and smooth feel. The semi-open exhaust design can effectively relieve the pressure of the cavity and control excess clutter reflection. Oxygen-free copper core with silver-plated surface can improve the efficiency of audio signal transmission.\n \n\n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_56e83424-1d8e-4a47-aca9-53f0019c6de1.jpg?v=1682581729","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_d0b87fa9-7d85-4e6d-81e1-11ddc9498372.jpg?v=1682581729","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3_072d4591-2d7f-4cf2-85ea-9298c7c425fa.jpg?v=1682581729","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_487a92be-f59c-45a6-8c4f-8fb4cd326d83.png?v=1682581729","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/8_9007a8e4-1e87-4780-8074-0cae80287383.png?v=1682581729","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_08ca06c6-5a05-43b0-9e5c-485b8aae59ab.png?v=1682581729"],"price":45,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.022Z"},"share_url":"https://firestarter.network/l/lst_mI18O2E-","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
