HiFiMAN Deva-Pro Over-Ear Full-Size Open-Back Planar Magnetic Headphone with Bluetooth Dongle/Receiver, Himalaya R2R Architecture DAC, Easily Switch Between Wired and Wireless, Bluetooth 5.0

Product Information

There is also a status LED at the bottom, though voice-prompts are there as well to let you know when the BlueMini has connected, disconnected, or put in pairing mode. This means that you will not get the low rumbling bass of other alternatives but that is not something that is really expected of an open back planar anyway. Compared to mainstream Bluetooth headphones, the Deva Pro are more resolving in the bass and treble and have better imaging.

Instruments such as the piano and the guitars sound rich and luscious, creating a relaxing ambience. However, this is marginal and fully compensated by the amazing sounding R2R system with above average naturalness and sonic culture. The saturation of the instruments is considerable, and the stage is not cramped, although it is wider, the depth can also delight.

Again, this is a small issue and I don’t want to overstate it, but I do also think this is responsible for some of the concerns I mentioned in the earlier sections.

HiFiMAN has a simplified look to all their product packaging nowadays, and the Deva Pro are no exception.I personally find that this style of headband does create a bit of a hotspot on the top of my head with extended use but for some reason, it doesn’t seem to be as uncomfortable (for me) over long periods as the Edition XS that I reviewed recently, possibly due to the cup shape and how the clamp to my face.

The headband is padded, has a metallic inner reinforcement and is covered with leatherette on the outside. The vocals are easily projected in front of you, the imaging of every single instrument is spot-on, they don’t get lost or compressed. The soundstage is impressive, with this open-back headphones you get an airy, resolute and detailed experience.What’s interesting here is that I would have thought one of the reasons for a new driver design would be to make it highly efficient and easy to drive for use with the small Bluetooth receiver, however when you use the Deva in wired mode, it actually requires a surprising amount of power (and current) - enough that I wouldn’t run it from a phone or a low powered amp.
