The images depict the headphone prototype and do not reflect the final product.\nCOMING SOON: Fully Modular Headphone System\nThe Zenfones are built around one simple idea: change is constant. Your listening habits evolve. Your favorite genre changes. Components wear out. The Zenfones embrace that reality with a fully modular headphone platform designed for fast customization, easy repairs, and long-term adaptability. Magnetic ear pads swap in seconds, drivers can be changed with a simple interchangeable system, and every component is built as a discrete, replaceable part.\nBuilt for change\nThe Zenfones are designed to evolve alongside your listening preferences. Elsewise Audio is developing multiple driver and ear pad options, each tuned for different genres, tonal balances, or listening priorities. Whether you want a more relaxed presentation for long sessions or a more energetic sound for electronic music and rock, the system gives you the flexibility to reconfigure your headphones without replacing the  platform.\nMagnetic ear pad system\nThe magnetic ear pad system allows you to swap pads in a couple of seconds without tools or frustrating mounting rings. Different pad materials and shapes can dramatically influence comfort, staging, bass response, and treble character. The Zenfones make those adjustments fast enough to encourage experimentation. \nQuick-swap driver design\nInstead of treating the drivers as permanently fixed components, the Zenfones treat them as part of the larger interchangeable system. Swapping one set for another is incredibly simple, allowing you to move between different sound signatures, genres, and listening priorities in seconds.\nRepairable by design\nEvery part of the Zenfones is a discrete, replaceable component. If something wears out or breaks, you can replace the individual part, simplifying maintenance, extending product life, and giving you direct own","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-headphone-apos-x-elsewise-audio-zenfones-modular-headphone-system-1240691572.jpg?v=1779993730","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-headphone-apos-x-elsewise-audio-zenfones-modular-headphone-system-1240691571.jpg?v=1779993669","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-headphone-apos-x-elsewise-audio-zenfones-modular-headphone-system-1240691570.jpg?v=1779993610"],"price":1500,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:55.771Z"},"share_url":"https://firestarter.network/l/lst_tzfetkV6","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
