Planar Magnetic drivers offer rich imaging, wide dynamics, and a soundstage that doesn’t feel boxed in. It’s powered by HIFIMAN’s stealth magnet system, an ultra-thin diaphragm, and the modular Bluemini R2R dongle, which slips into the left earcup and delivers hi-fi sound through a tiny R2R DAC.\n\nStealth magnets for less distortion\n\nConventional magnets can often get in the way of the sound waves they’re supposed to be helping. HIFIMAN’s Stealth Magnets don’t. They’re shaped to reduce diffraction and acoustic interference, allowing the diaphragm to move freely. That means cleaner transients, less distortion, and an open, natural sound.\n\nUltrathin diaphragm for faster transients\n\nHIFIMAN’s NsD (supernano diaphragm) is 80% thinner than previous designs. That gives it less mass to move—which in turn means faster impulse response, lower distortion, and a more detailed image across the frequency spectrum. Transients are crisp, bass stays tight, and vocals come through with lifelike clarity.\n\nWired or wireless\n\nThe DEVA Pro supports both dual-sided 3.5mm TRS and single-sided 3.5mm TRRS cables (left socket). The TRRS jack is also used to connect the Bluemini R2R dongle, which converts the DEVA Pro into a fully wireless headphone. The dual-socket design gives you flexibility to use the cables you already own—or to switch between wired and wireless as needed.\n\nR2R DAC in your earcup\n\nThe Bluemini R2R is a self-contained Bluetooth DAC and amplifier with a true resistor ladder (R2R) DAC built in. Based on HIFIMAN’s proprietary HIMALAYA DAC architecture, it skips oversampling entirely for a more natural signal path and analog-like smoothness. At just 20mW power draw, it’s also extremely efficient.\n\nClean signal with low power\n\nThe HIMALAYA DAC in the Bluemini draws far less power than conventional Sigma Delta DACs—only 20mW—while matching or ","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354858.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354859.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354860.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354869.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354868.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354867.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354866.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354865.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354864.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354863.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354862.jpg?v=1768586754","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-deva-pro-planar-bluetooth-headphones-1170354861.jpg?v=1768586754"],"price":199,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.629Z"},"share_url":"https://firestarter.network/l/lst_OJLcvm9s","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
