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

Yet, some might say that this Pro version looks a bit pale compared to the luxurious brown-silver color combination of the original.

For bass and mids, this difference in detail is maybe not as noticeable but I think that’s just because treble frequencies often have an easier time of indicating these issues. Introduction​Looking at how big Hifiman has grown over the last few years it’s not a surprise, that they’re pointing their heads towards new and interesting segments of the audio market.

Personally, that’s not something I’ve fully seen the advantage of yet, but for those who really care about it, this may be a suitable solution. I haven't tested with applications like Neutron or UAPP which supposedly can bypass the internal volume software of the host device but with streaming services like Tidal and Qobuz you get the volume limit, so this is something to consider if you plan on using it this way.

So for example, if something has a congested type of sound, it can be improved by adding elevations or recessions to make it sound more normal.The battery life is about 8 hours, and this module packs some meat, driving the Deva Pro very effortlessly and with authority. The stealth magnet sticker points to the revised driver design of this model—more on the driver redesign later in the Sound section. As I mentioned above, the bottom of the module houses the microphone, a status LED, the USB-C port and a single button.

As always, they have not requested anything at all and I will include a link to the Deva Pro on the official Hifiman site because I feel that it is the least I can do. Of course despite being a wireless headphone, it is not suitable for outdoor use due to the fully open design and the loose fit. Today, it all changes, as the Deva Pro is just a vastly upgraded Deva, something I thought wasn’t going to happen in a while. In addition it offers multiple ways to enjoy its sound, be it USB, BT or the power of your own amps.First of all – the Deva Pro is not tuned as the rest of Hifiman’s lineup, just like the original Deva. Apart from that, the Deva sounds very similar for detail retrieval to their older HE-400i (one of their older headphones), or perhaps HE-4XX from the Drop collaboration. Build quality is very similar to HE400SE that I have tested as well and nothing much to shout out about, it keeps the weight light and it works, so that’s fine by me. My previous experience with the HE400SE and RE400 was very successful and resulted in many hours of listening.
