{"type":"firestarter.listing","listing":{"id":"lst_dIt3i0vf","product_name":"DDHiFi BC150B-490","category":"Audio Cable","description":"\n\nDual-Connector Design for Enhanced Audio Quality\nThe decision to employ dual connectors for the BC150B-490 is rooted in ensuring consistent sound across both left and right speakers of the HD 490 PRO. While a single-sided connector could achieve balanced sound, the dual-connector setup maintains audio integrity, preventing any perceived thinness due to the headphone's built-in head beam wiring.\n\n\nMini-XLR 4Pin Connector with Latching Mechanism\nSennheiser's choice of the Mini-XLR 4Pin connector for the BC150B-490 upgrade cable reflects a commitment to professional-grade reliability. However, prolonged use may result in slight wear and tear, such as minor peeling of the lacquer finish on the part inserted into the headphone socket, caused by repeated plugging and unplugging.\n\n\nAccurate and Detailed Monitoring Capability\nThe HD 490 PRO headphones demand a high level of driveability to deliver optimal performance. Utilizing the BC150B-490 balanced 4.4mm cable transforms these monitoring headphones into versatile music headphones. Compared to the 3.5mm single-ended plug, the balanced cable enhances listening comfort and enriches both low and high-frequency details, enhancing the overall audio experience.\n\n\nEnhanced Longevity and Reliability\nDesigned with durability in mind, the BC150B-490 ensures prolonged performance under demanding conditions. This reliability makes it an ideal choice for audiophiles and professionals seeking consistent and high-quality audio reproduction over time.\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/BC150B-490-JPG02.jpg?v=1718345966","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/BC150B-490-JPG05.jpg?v=1718345966","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/BC150B-490-JPG01.jpg?v=1718345966","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/BC150B-490-JPG03.jpg?v=1718345966","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/BC150B-490-JPG04.jpg?v=1718345966"],"price":139.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:46.063Z"},"share_url":"https://firestarter.network/l/lst_dIt3i0vf","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
