This provides ample power for a wide range of headphones, ensuring dynamic headroom and distortion-free performance.\n\n\nJAN6418 Tube Output\nUnlike conventional dongle DACs, the XI2 integrates dual JAN6418 tubes, blending the warmth and musicality of analog sound with modern digital precision. The tubes are discreetly housed inside the body, with two side windows offering a subtle visual glow.\n\n\nCompact Screen &amp; User Interface\nMaintaining the 0.87-inch OLED screen and intuitive UI from the XI1, the Beta XI2 allows users to monitor playback formats, volume, and settings with ease, ensuring convenience in a portable form factor.\n\n\nRefined Design\nWhile similar in style to the XI1, the Beta XI2 adopts a slightly longer and wider chassis to accommodate its upgraded components. The design balances elegance and durability, making it a stylish yet functional portable DAC solution.\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3_ONIX_XI2_1.png?v=1757054089","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3ONIXXI2_2.jpg?v=1757054089"],"price":349,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.685Z"},"share_url":"https://firestarter.network/l/lst_PaueQv1F","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
