Hifiman Deva Bluetooth Headphones

Product Information

Unlike the sound waves created by a conventional magnet, the special shape of Stealth Magnets enables the waves to pass through the magnets without generating interference. HIFIMAN’s advanced magnet design is acoustically transparent, dramatically reducing wave diffraction turbulence that degrades the integrity of the sound waves. If you are extremely sensitive to upper-treble, the HE400se might be fatiguing in the long run. Those who like airy treble should have no problem with this peakiness. I find this peak too much though and prefer to EQ it down (or modify the headphones, more on this below).

HiFiMAN Deva review: less wires, more fun - Soundphile Review

The HIFIMAN Deva Pro was sent to me by HIFIMAN in exchange for an honest review. No monetary exchange took place. This is 100% my honest opinion. 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. With very complicated music it sounds not AS accurate and spacious as many headphones on the market, but considering the price and once again, the wireless aspect, the Deva Pro plays in its own league, while all the other kids can just sit and watch.Unfortunately, the upper-midrange is quite intense. There is no noticeable frequency dip between 2-5kHz, resulting in a very up-front midrange. Such tuning also hampers soundstage depth and microdynamics. One more question, For Deva Pro Wireless, Are the DAC/AMP electronic components and the battery inside the headphone's ear cups ? or are they inside the Bluemini R2R ? Both of these issues are solved on the Deva Pro courtesy of the included BlueMini R2R module that can be detached as needed.

DEVA Pro with Bluemini R2R--Combining the Best of the HIFIMAN DEVA Pro with Bluemini R2R--Combining the Best of the HIFIMAN

The grille mod consists of basically removing the grilles from the cup. To do that, you have to detach the ring surrounding the grille and then the grille just pops out. This video is helpful if you’re unsure about how to go about it. The grille mod is simple to implement but offers tangible benefits. Good control and well-behaved, more reactive to multiple bass lines now, allowing for keeping them separated yet also in line, meaning the Deva Pro can handle pitch differences and not lose composure – a sure sign of the driver being able to keep up during more complex parts due to its better speed, resolve and driver control. 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.Does Deva Pro use stealth magnets ? what are the benefits of stealth magnets ? What other headphones use stealth magnets ? Bass starts rising from 30Hz and becomes noticeable around 40Hz. Bass response is pretty much flat. In BT mode there is more emphasis near the sub-bass it seems, though the bass sounds rolled-off after 35Hz in all three modes (Bluetooth, USB, and wired).

SE, Creative Aurvana Live! 2, Sennheiser PX 100-II, Panasonic RP-HTF600-S, Pioneer Steez 808, KOSS KSC75, KOSS KSC35. I personally use the Sonorous III the most, though in terms of resolution I’d say Deva Pro is the best among these.

Our Verdict

The Himalaya is rather neutral, faithful to the original source and does not run some kind of DSP to specifically match the Deva Pro. The Bluemini R2R dongle delivers about 230mw. I think they mean @18 Ohm, otherwise this would not make sense to me. Its bluetooth module (R2R) is also better, you lose less bass extension by using it. (In theory, you could use the new module with the old Deva for the same effect.) So, the actual build quality of the Deva Pro is pretty good, absolutely no complaints here. The headband regulation feels sturdy yet smooth, the weight distribution is excellent and every part that touches your skin feels pleasant. Also, they feel like they could take a beating, quite substantial in hand and not at all fragile. It feels more premium and durable than the 400se for example, as it should, considering the price gap. The connections used by Hifiman on the Deva Pro consist of a dual connection, one 3.5mm connector on each cup, however, the left cup also accepts a 3.5mm TRRS connector, which is how the Bluetooth module is connected. This is a system that allows the Deva Pro to be used with both the BT module and the normal cable that is included. It also opens the possibility of using other aftermarket cables of your choice. This is something that was a complaint from many with the Ananda BT, the fact that it could only be used via BT or USB, the Deva Pro solves this issue in a way that I find well thought out and implemented.
