The HiFiman Deva Pro magneto-planar headphones are built using the proprietary Stealth Magnets technology – this is a grille of acoustically invisible “invisible magnets” (as they were called in HiFiman). This design is immune to parasitic interference – according to HiFiman, “reduces the turbulence of wave diffraction, which degrades their integrity.”
The Deva Pro’s HiFiman Neo “supernano” (NsD) diaphragm is 80% thinner than the previous model, the HiFiman Deva . According to the manufacturer, it will provide fast response and detailed audio stage with great full-range sound. The cost of new items in comparison with the previous model has increased by about 10%.
HiFiman Deva Pro can work like ordinary cable headphones – for this, 3.5 mm jacks are provided – both in unbalanced and balanced versions. The second connection option is the “compact but cool” Bluetooth / USB-module (DAC) Bluemini R2R.
It also connects to headphones, making the left cup slightly (25g) heavier. Inside – a compact DAC with Himalaya R2R architecture and a dynamic range of 118 dB. Oualcomm Bluetooth module supports LDAC, aptX HD, aptX, AAC and SBC codecs.
Deva Pro provides a frequency range of 20 Hz – 20 kHz with an impedance of 18 ohms and a sensitivity of 93.5 dB. On a single charge of the Bluemini R2R battery, the headphones are ready to work in wireless mode for about 8 hours.
In the US, HiFiman Deva Pro headphones will cost $ 330.
