For around $300, you’re getting:
A full-sized planar magnetic headphone. We’ll get into why that’s important later.
The Bluemini Adapter for your phone, which also doubles as a separate Amp/DAC.
A balanced 3.5mm detachable cable. We’ll get into why that’s cool as well. Do be aware that you will need a cable like this if you want a fully balanced connection. HIFIMAN’s cable itself is only “balanced” going into the cup. The other end is a traditional single-ended connection.
USB-C to USB-A Charging Cable that you can also use from the Bluemini into your PC.
A well-designed user guide.
That’s a whole heck of a lot of value for your money. Most headphones out there come with maybe a ¼” adapter and a case if you’re lucky. As much as I love AKG headphones, my 702 and 612 came with pretty bare bones. For what I paid, it was a tad disappointing.
The DEVA really satisfies like a Snickers.
YOU’RE NOT YOU WHEN YOU’RE HUNGRY!
You can do just about anything with it:
You can use it wirelessly with a phone, using either the Bluemini or something like a FiiO BTR5.
You can use it wired on your desktop, with the supplied Amp/DAC, or with a separate Amp/DAC of your choosing. They aren’t too hard to drive but do happen to be fairly inefficient, meaning they require quite a bit of power from an amp to reach an acceptable listening level. Something like a FiiO K5 Pro is my preferred desktop homie.
Because the cable is detachable, you can use it as a gaming headphone with something like the Boom Pro and a Creative G6 on your console. You can also use an attachable Mod Mic if you want.
It has a built-in microphone for calls.
The previous generation HIFIMAN headphones were above average in terms of comfort, but the DEVA takes it to another level. I’ve been listening to it since Spring of 2020, and haven’t once had to take it off my head or adjust it one single time due to discomfort, for any reason whatsoever.
This is perhaps the most comfortable headphone I’ve ever worn out of over 100 at the time of this review, right up there with a Beyerdynamic or Philips SHP9500.
The clamp is just right, the headband padding never digs, and the cups are large enough to envelop your ears. It does tend to slide a bit at times, but that’s a minor nitpick and does not apply to how it actually feels when I’m wearing it.
I’m giving this its own section because it’s super important to understand how far HIFIMAN has come from where they were.
At one point, the quality control issues with their headphones got so bad that Audio Advice here in my hometown dropped them from their lineup. I personally had problems with Ananda’s connection cutting out on the right or left side of the earcups, and it was super frustrating, to say the least given how much I enjoyed the sound.
The 400 series models were also known for breaking down, whether it be the bale, the shoddy yokes, the pads coming unglued, etc.
With the new generation DEVA and 2020 revision 400i, most of that has been rectified. No more connection issues, no more build issues. I will caution you about the earpads, as it still looks like they’re attached in the same less than ideal way, but as long as you’re not constantly swapping them out you should be fine.
Dekoni makes pads that HIFIMAN should manufacture themselves, but that’s a rant for another video.
The headphone has functioned flawlessly for me since Spring of 2020, and it’s built like a tank without being too heavy. It really feels just right on my head and I can’t say enough good things about it.
The best quality about the DEVA is how it portrays well-recorded music. I’ve always said that planar magnetic headphones do tend to outperform their dynamic counterparts, and that sentiment certainly holds true here. What is a Planar Magnetic Driver?
Specifically, Instrument Timbre is the one quality about a planar that makes it stand out from the crowd. What is Timbre? Everything sounds tonally correct, giving you a true sense of how an instrument may sound in real life vs. the way it sounds through a conversion process.
The bass and mid-range on HIFIMAN headphones are also exemplary, and they respond well to EQ if you want to be all Metal571 about it.
I will caution you on the treble, as it’s a bit hissy at times. Still, you can EQ it down if you want and to be honest, it kind of goes away the more you listen. That’s a phenomenon for another video as well. YEAH WOO!!
So why not pick one up today? You won’t regret it. If you do, I’ll eat my sock. AND THAT AIN’T HAPPENING, HOMIE!
