INTRO
Welcome to the review of the Hifiman R9. In the previous reviews of youtube we saw the headphone tank, the Dt1990 pro. In this video we are going to look at an overlooked Hifiman model, the Hifiman R9. A closed overe ear model with a dynamic driver. Yes. You have heard well about dynamic driver and the company Hifiman... I say this because Hifiman is a brand that focuses on magnetic planar driver headphones. This Hifiman R9 joins some iconic dynamic drive models from the company. Their first dynamic headphone was the HE-300, a model launched in 2011. Although it was undoubtedly a good product, it was not destined to turn the audio world upside down, mainly because of the market it was aimed at.
So after many years Hifiman announced the R-10D and R-10P, and it was one of the most controversial announcements. Based largely on the legendary Sony MDR-R10 with its huge, asymmetrical earcups, Hifiman sure caught a lot of attention. Some time has passed, and Hifiman has released another model in this line, the HE-R9, which we are going to review today. It should be noted that it is a headset that can also be used with the bluemini R2R device to make it wireless. Obviously this analysis has been done using a cable. In fact, I don't have that accessory since my pack was so-called wired.
The Hifiman R9 has a current price of no more than €250, although it can be found on the website itself for less. I want to highlight that the launch price was about €600 and in recent months it has been progressively reduced until it is below €300. The inclusion or not of the receiving device can increase the price.
UNBOXING SECTION
he packaging is very simple. A subtle cardboard box where the headset comes. We have a hard foam for the headphones, which is used as padding during transportation. This is a very nice touch, as it can be used as a stand for headphones.
On the other hand, and almost to finish we have a rubbery cable that complies along with the classic 6.3mm adapter. The cable is not bad but I don't think it is anything out of this world either. Don't expect a case or carrying bag for the headset.
In short, we have a very similar package in terms of accessories compared to the Edition xs, for example.
The
design of the headset is certainly peculiar. As mentioned at the beginning of this review, the headphones are heavily influenced by the legendary Sony MDR-R10, widely considered to be one of the best headphones ever made. I do not recommend the headset for use outdoors as they are too conspicuous and large. However, they are very light at 328 grams…or rather; They feel very light. The slightly padded headband is not too tight and distributes the weight better than the Edition xs, a headset that used the same headband and the pads, being so large, fit very well. In general, I classify them on par with the Dt1990 pro or the Sivga Sv021/Sv023 in terms of comfort since I don't notice any fatigue with them on and I could go two hours straight without noticing any discomfort.
The
construction seems quite solid to me. It is true that they are not all metal, in fact the cups feel somewhat plastic but the whole thing feels more than solid and well built. The mix of materials such as the hybrid synthetic leather and nylon pads, CNC aluminum for the gimbals and plastic pivot blocks together with those pronounced red cups give a feeling, quite subjective, of better construction for example than planar models like the Edition Xs or original Ananda which feel somewhat more delicate.
The Hifiman R9 is classified as an innovation using some of the technology that was already innovative.
We have what Hifiman calls Topology Diaphragm." A diaphragm that was used in the R10-D. It's basically a special diaphragm with a nanoparticle coating applied to its surface. The result is a more natural and detailed sound.
The depth of the cups is to ensure that the sound waves from the transducer do not collide as much with the typical space problems that flatter closed headphones suffer from. Smaller closed cups tend to create unnatural echoes.
All this must be added to the Bluemini R2R module. It's built around an R2R DAC, which for the size and price of this little accessory is simply mind-blowing. Hifiman is releasing more and more headphones that can be used with the Bluemini R2R, and it's a fantastic way to increase the functionality and value of their products...but how does it sound?
The R9 is a big, bold, warm-sounding headphone that deviates greatly from what Hifiman usually offers. But before talking about the sound, clarify that...
Isolation
We have pretty standard passive isolation inside closed-back type headphones. In fact, despite being closed, we did not notice that it insulated much, possibly due to the strength of the headband, which is not very high. The leakage or sound that leaks is not very loud and it behaves like a closed headphone. It will barely be heard outside unless you have a very loud volume...I do not recommend listening to music at high volume.
The signature
Will a powerful amplifier be needed?
There is nothing dramatic about amplification. The drivers are 32Ω and 100dB, so the R9 is easy to drive. Just grab whatever DAC and amp you have and use the R9s. With the Ifi hip dac through the normal 3.5mm output, which gives more than 250mw at those 32 ohms, 100% of the headphone is used.
SOUND SECTION – TECHS
In the sound scene we have one of its key points. I will be brief, it is perceived as an open earphone. We have a wide…very wide soundstage. Above all, I highlight it on the Y axis, that is, in height. On the kind of sounds like classical.
The instrumental separation is not far behind... it is another of its strong points, as is the soundstage. It has a large separation between the instruments, resulting in a very precise image and a very convincing 3D effect.
Definitely; Most of the open-back headphones I've reviewed in recent years reached good soundstage levels, but seeing a closed-back do things like this is impressive. If you are looking for closed headphones with a wider range than an open one, look no further.
SOUND SECTION – BASS
Let's start with the bass. The R9 has a closed back and uses a dynamic controller, so you should expect a fun and enjoyable type of experience…and it is. The HE-R9 is a king of fun when it comes to low frequencies, resulting in a very different sound signature than what I'm used to with the rest of their line.
The R9 shines the most with electronic, metal, rock and hip-hop music. The R9's bass feels big and makes the headphones vibrate when listening to some bass-heavy tracks at a moderately high volume. However, do not think that it is exaggerated or that it lacks control, as that would have been far from the truth. The R9 has a great understanding of low frequencies, delivering an exceptional amount of dynamics and texture. It doesn't extend as low as the best planars, mainly due to the limitations of the driver technology...
SOUND SECTION – MIDS
The midrange is quite warm, especially considering that we are talking about Hifiman headphones. The entire midrange is smooth and very pleasant to listen to, so it continues that fantastic fun factor that the bass offers, giving you great mids when it comes to long listening sessions.
Vocals on the R9 end up sounding melodic, rich and yet natural, with added body. Everything sounds big and bold on the R9. It has the ability to put you directly into the music and make you dance, offering a very rich, smooth and colorful presentation.
SOUND SECTION – TREBLE
While it will never sound harsh or unpleasant, you can get quite different results depending on the system you are going to use the R9 with.
The overall treble presentation is again smooth and romantic, with good detail. It has enough power to make your electronic or metal tracks sound prominent and very dynamic, but at the same time, it won't bother you with peaks or unnecessary false sharpness.
All in all, the treble doesn't sound too forward, so you'll have fun even while listening to poorly mastered albums. It's just a different flavor, a more "classic" approach to the treble, that has that sweet timbre and great body to the sound. What's also worth noting is that the treble extends quite high.
SUMMARY SECTION
Before recommending or not recommending this headset, I would tell you to try it first. It's something I recommend doing with all headphones, but with this one more so. I find many opposing opinions which make me think of some batch in poor condition, defective unit, bad amplification... My opinion about this R9 is that it is simply the most complete closed headphone that I have tried ahead of the Sivga sv021 or the Focal Elegia itself.
A fun headphone to listen to, with a very large stage, excellent instrumental separation, natural timbre and on top of that, comfortable. For me, his discovery was more than positive.
Yes, the bass has a tendency to bleed the lower midrange slightly, but I think that's a good thing in this case, providing vocals that add richness and natural warmth.
I would call the R9 a rich sounding headphone that is fun, yet relaxed overall. It's also not intense in any specific area, which may sound ironic, but I don't know how else to explain it. This model is aimed at people who simply like to have fun and enjoy their music, especially the more dynamic genres. Hifiman already has many headphones that are perfect for everything, very universal and with an excellently technical sound, the R9 is something different...yes, I recommend it.
¡See you in next videos & reviews!
What the HE-R9 does have is potential. There's nothing wrong with the drivers. These can be used as a good starting point for anyone willing to spend the time to modify them. It took JM Audio eight tries to get something they think is worthwhile, so if you are going to keep the original cups, you've got your work cut out for you in modding, but that is part of the fun. I'd suggest going the route I took, which was removing those ridiculous, cavernous, echoey plastic cups and replacing them with wooden cups. Turning them into semi-open headphones lets the drivers have the air they need.
