It brings HiFiMAN’s NEO “supernano” diaphragm and Stealth Magnets, from a family that includes the flagship Susvara, to a comfortable, easy-to-drive design. Use it with the supplied cable like any hi-fi headphone, or plug the Bluemini R2R module into the left earcup for LDAC and aptX HD Bluetooth through HiFiMAN’s own Himalaya R2R DAC.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/hifiman-deva-pro-open-back-planar-magnetic-headphones-with-bluetooth-attachment-photo-hero.jpg?v=1791346651\" alt=\"HiFiMAN Deva Pro planar magnetic headphones with the Bluemini R2R\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eNEO supernano diaphragm\u003c\/h3\u003e\n\u003cp\u003eHiFiMAN’s NEO supernano diaphragm (NsD) is 80% thinner than its previous designs, for a fast response and a detailed image with lush, full-range sound.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/hifiman-deva-pro-open-back-planar-magnetic-headphones-with-bluetooth-attachment-photo-nsd.jpg?v=1791346657\" alt=\"The NEO supernano diaphragm of the HiFiMAN Deva Pro\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eAcoustically invisible Stealth Magnets\u003c\/h3\u003e\n\u003cp\u003eConventional magnets disturb the sound waves passing through them.

Inside is HiFiMAN’s Himalaya, an ultra-small R2R (resistor-ladder) DAC built on a non-oversampling concept, with low energy consumption and high sample rates. HiFiMAN measures it at a 120dB signal-to-noise ratio and 0.0022% THD while using about 20mW, a small fraction of what typical DAC chips draw. The Bluemini R2R weighs 25g, gives 6 to 7 hours per charge and measures 114dB SNR; when you don’t need it, unplug it and listen wired without the extra weight.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/hifiman-deva-pro-open-back-planar-magnetic-headphones-with-bluetooth-attachment-photo-bluemini.jpg?v=1791346665\" alt=\"The Bluemini R2R Bluetooth module of the HiFiMAN Deva Pro\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/hifiman-deva-pro-open-back-planar-magnetic-headphones-with-bluetooth-attachment-photo-himalaya.jpg?v=1791346670\" alt=\"The HiFiMAN Himalaya R2R DAC in the Bluemini R2R\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/hifiman-deva-pro-open-back-planar-magnetic-headphones-with-bluetooth-attachment-photo-snr.jpg?v=1791346673\" alt=\"Signal-to-noise ratio of the HiFiMAN Himalaya R2R DAC\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/hifiman-deva-pro-open-back-planar-magnetic-headphones-with-bluetooth-attachment-photo-phone.jpg?v=1791346677\" alt=\"HiFiMAN Deva Pro with the Bluemini R2R and a phone\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eWired, two ways\u003c\/h3\u003e\n\u003cp\u003eEach earcup has a 3.5mm socket for the supplied dual-sided 3.5mm TRS cable.
