{"type":"firestarter.listing","listing":{"id":"lst_ubXiJpJc","product_name":"FiiO x JadeAudio JM21 Android 13 Hi-Res Music Player","category":"DAP (Digital Audio Player)","description":"Android 13 Hi-Res music player\nThe JadeAudio/FiiO JM21 is a slim Android 13 Hi-Res music player built around a Snapdragon 680 platform and a fully balanced audio stage with dual Cirrus Logic CS43198 DACs. It is made for daily listening with streaming apps, local files, and reliable portable power—plus a bit of extra care for audio purity when you use third-party players or a USB DAC.\nSnapdragon performance that stays out of the way\nThe JM21 uses a Snapdragon 680 built on a 6nm process with an 8-core Kryo 265 CPU up to 2.4GHz, which helps the player feel quick when you are browsing libraries, switching apps, or managing downloads. The efficient platform also supports long listening sessions without constantly thinking about battery.\nAndroid 13 with the apps you actually use\nThe JM21 runs a customized Android 13 open-source system, giving you access to common streaming services and everyday audio tools. Install what you want—Spotify, Apple Music, and other apps—then control playback the same way you would on a phone, but focused on audio playback.\nDual CS43198 DACs with a balanced output stage\nInside is a fully balanced audio architecture using two Cirrus Logic CS43198 DACs and two SGM8262 op-amps. The balanced headphone output is rated up to 700mW + 700mW, which is useful if you rotate between sensitive IEMs and harder-to-drive over-ears and want headroom without hauling a separate amp.\nThin, light, and built for pockets\nAt 6.46 x 4.17 x 1.77 in (16.41 x 10.59 x 4.50 cm) package size and an item weight of 10.6 oz (300 g), the JM21 stays easy to carry. The player itself is described as 13mm thin and 156g (5.51 oz), which makes one-handed use feel natural when you are commuting, walking, or moving around the house.\nBattery life that covers a full day of listening\nFiiO quotes up to 12.5 hours of battery life, which fits a typical day—morning playlists, afternoon work, and evening listening without hunting for a charger. The JM21 uses a built-in lithium polymer battery, ","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697336.png?v=1769027409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1220503228.jpg?v=1770812888","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697335.jpg?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697328.jpg?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697331.jpg?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697330.jpg?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697329.jpg?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697325.jpg?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697327.jpg?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697326.jpg?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697334.jpg?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697333.png?v=1770237332","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dap-digital-audio-player-fiio-x-jadeaudio-jm21-android-13-hi-res-music-player-1217697332.png?v=1770237332"],"price":259.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:56.101Z"},"share_url":"https://firestarter.network/l/lst_ubXiJpJc","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
