The HiFiMAN DEVA Pro is much more than just a simple upgrade, whether listening via wired or via Bluetooth with the new Himalaya R2R DAC. It features the Stealth Magnet technology, which also was recently introduced in the new Arya headphone.
This magnet technology is acoustically transparent, dramatically reducing wave diffraction turbulence that degrades the integrity of the sound waves. Resulting in a greater accuracy of the  the sonic output. Another positive result of the Stealth Magnets design is that the DEVA Pro is easier to drive, offers better imaging thus creating a more accurate soundstage.
The DEVA Pro comes with the new Bluemini that is now equipped with HiFiMAN’s own DAC chip the HIMALAYA. which features the R2R architecture. A chip composed of an array of resistors with a new algorithm reduces power handling between the chip and peripheral components. As a result, signal-to-noise ratio, total harmonic distortion, and energy consumption are at their most efficient and cost-effective. The Bluemini dongle supports high-resolution codecs such as LDAC and aptX-HD, making it well-suited to most currently available high-definition streaming devices. Playback time is 8 hours.
In addition to its wireless connectivity, the Bluemini R2R dongle can be used as a powerful integrated DAC/amp for audiophile-grade performance from smartphones and other low-power devices simply by connecting a USB-C cable. A built-in amplifier module provides more than 200 mw per channel, and the two-channel high-fidelity DAC/filter ensures exceptionally detailed sonic output, no matter the source.
The DEVA Pro has an impedance of 18 ohms, sensitivity is rated 93.5dB, and it weighs 360 grams. A double-sided 3.5mm balanced input accepts stereo cables and the Bluetooth R2R dongle.
