{"type":"firestarter.listing","listing":{"id":"lst_mwpakVil","product_name":"7HZ Sonus","category":"Earphones/IEMs","description":"\n\n\n\nFlawless Integration of Technology\nThe 7Hz Sonus was meticulously designed around a single balanced armature (BA) driver combined with a powerful dynamic driver (DD). The difficulty in many hybrid IEM’s is achieving a continuous and uniform sound. The Sonus focused on achieving the perfect singularity to mitigate this issue. With careful acoustic and electrical engineering, the Sonus achieves a coherent union of the BA and DD drivers. This means that in timbre, tonality, and technicalities the sound is completely synergistic across the whole frequency spectrum, revealing layers of audio nuances in every note.\n\n \n\n\n\nPrecision Unleashed\nThe 7Hz Sonus boasts a complete coverage of the full frequency spectrum, from 10Hz to 20,000Hz. This mean every audible note and micro details are captured and faithfully reproduced to your ears. The deep-reaching lows also means drums and bass lines are powerfully delivered, resulting in the most resounding bass impact and speed. With a remarkable total harmonic distortion (THD) of under 1%, the 7Hz Sonus combines delicate details with a strong bass presence.\n\n\n\n\n\nInspired by Nature’s Harmonious Design\nThe 7Hz Sonus was conceived from inspirations from the symphonies within the natural world. If you listen carefully to the natural beauties of the outdoors, you can hear the music of nature, filled with both melodies and harmonies. The Sonus encapsulates this beauty by bridging art and science. Like the layers of leaves in a forest, the combination of the BA and DD drivers provides rich layering in the music, allowing every note to be heard.\n\n \n\n\n\nArtistry in Ergonomic Construction\nThe 7Hz Sonus is designed for long comfortable listening sessions. The front chamber is composed of medical-grade materials that optimize sound propagation as well as a safe contact point for your skin. The back is composed of aviation-grade lightweight aluminum, which makes for a durable, yet light casing. The shape of the Sonus is precision designed and","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0643.jpg?v=1692779283","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0663.jpg?v=1692779282","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0655.jpg?v=1692779282","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0645.jpg?v=1692779280","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0446.jpg?v=1692779280","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0442.jpg?v=1692779281","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0440.jpg?v=1692779282","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0433.jpg?v=1692779280","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0423.jpg?v=1692779281","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0419.jpg?v=1692779280","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0413.jpg?v=1692779281","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/203A0412.jpg?v=1692779283"],"price":59.99,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:46.844Z"},"share_url":"https://firestarter.network/l/lst_mwpakVil","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
