AKG old and new professional headphones side-by-side comparison
I am an AKG fan and have owned the AKG Professional Headphones flagship K702, the AKG Professional Monitor Headphones K240DF and the AKG Generation Entry Classic Earbuds K314P before owning the Q701. AKG has a noble Austrian pedigree. Its sound direction has always been known for its natural fidelity, clarity and nobility. So what's the style of this new AKG flagship Q701?
I've had the Q701 for about a week now and have been working overtime to boil it during that time. According to the AKG manual, the Q701 needs 1000 hours of boiling time. Couldn't really wait that long. Up to the actual test, I have boiled the unit for about 120 hours, boiling method: pink noise + big dynamic symphony. The so-called pink noise is the murmur of a radio without a station.
As the saying goes, a single tree does not make a forest. No AB, All Gods. For this test, I also moved out 2 opponents, one being the K702 and the other being the K240DF - both being the best of the AKG professional headphones.
Generally speaking, AKG headphones are notoriously hard to push, which means that AKG headphones, when you want to play them well, are hard! This is true from the K501 and K601 to the K701 and K702, and even less so for the classic 600Ω K240 series.
When the Q701 series appeared, it was based on the concept of "easy push". So, for this test, we'll start with the lowest-end $100 MP3. Due to the difficulty of pushing the K240DF, the Q701 will be compared to this classic on the final desktop system.
A hundred dollars mp3 and SONY HD5
Have a hundred dollar plundered American RCA brand mp3 on hand. Because the push is so small, the Q701 still has to be cranked up to the top to come out loud, despite its mere 62Ω impedance. The good thing is that the Q701 has no bad sound, but the sound is a bit on the soft side. And K702 picks up and is more of a gas.
The Sony hd5 pushes straight through and works a little better than that $100 mp3, but still doesn't drive the Q701 adequately. The sound that came out was also very average, let's just say it didn't make a bad sound.
Second, the computer integrated sound card
I have a computer with integrated sound card ALC662 under which all volumes are added to the top. Both the Q701 and the K702 make a lot of noise. This time a difference emerged. K702 still looks scattered, while Q701 is starting to flex its muscles!
The violin under the Q701 has a clear sense of string rubbing, the low end starts to coalesce and the volume is spot on, the vocals seem a little warm and the sound is lively and the soundstage is extended. The feel of a high-end headset is starting to show through.
III. State of Music Xuan Yuan II
This sound card was a powerhouse of the year for Razorback. The quality is not up to HIFI level, but it still has strengths that should not be underestimated.
On the Regulus II, the Q701 further shows her great strength. The sound is transparent and clear, with a wide soundstage, and very accurate expression of the classical sound when listening to small compilations. The female vocals, in particular, are delicate and beautiful, and Faye Wong's ethereal voice is soothing.
The K702's strength is also starting to show, but the K702's high-frequency burr is more serious, the midrange vocals are farther away compared to the Q701, the three frequencies are more balanced, and the low-frequency texture is good in terms of volume.
Four, SONY HD5+AURORA
The Sony hd5 + AURORA ear amps are a combination that features good quality, good rhythm, and pushing power that is considered superior in a walkman device. Usually, the author uses it mainly to push ER4S.
With both headphones pushed, the volume knob on the earphones was set to the 1 o'clock position, well above the 150Ωer4s.
Under this system, the K702's sound is clear, delicate and dynamic, with the first signs of dominance. Probably due to the limited thrust, various aspects such as positioning, conjunctions, and the strength of low frequencies seem weak, while the sound seems indescribably ethereal and comfortable, listening to Faye Wong is really great. Unfortunately the vocals are slightly further away.
Q701 in this system, three frequency balance, comfortable vocals, sound field is also quite wide, low frequency is slightly scattered, volume is rich, violin has good sense of string rubbing, overtones and details. It's quite a bit better than the K702.
V. ARK MX + GEMINI MX
This is a system that is considered a telling combination in PCHIFI. And this system is characterized by high quality, faithful reproduction of the recording without adding MSG to the sound.
As a whole, both the K702 and Q701 retain the delicate, fresh and gorgeous sound direction of the AKG, a flavor that can be fully appreciated from the body of the entry-level K314P as well. Both headphones are generally well-balanced, high quality and have excellent resolution in all three frequencies. The K240DF, on the other hand, seems very austere, with barely a hint of coloration, giving the most faithful sound. Here are some specific differences.
Q701
Of the three headphones, I personally feel that the one with the most tonal coloration is also the warmest, with a bit of a warm sound. The vocals are closer together, as the midrange is a little tinted, and the vocals, especially the female vocals, are very warm and comfortable, yet different from the Japanese kind of sultry feel. Instead, it adds some moistness while retaining the original flavor. The smaller classical performance is more on point, with a good violin performance.
Compared to the K702, it is a bit weaker in terms of big dynamics, especially on "A Sister Drum", and the Q701 has the weakest dynamics of the three.
In addition, the Q701 is lacking in its ability to handle large compilations of classical. Maybe these have something to do with the Q701 not being fully boiled.
But one thing that struck me about the Q701 is that it's easy to forget about the equipment, forget about the separation of the three frequencies, forget about locating the soundstage junction, and go listen to music in peace. This is similar to the K240DF.
K702
The K702 is actually the one headset that most resembles the Little Four, more so than the DT880. She has a clean and clear voice and a delicate sound. It has a good command of large classical compilations, with a wide soundstage, accurate positioning and a rich image. More importantly, it also has a good "hall feel". The small compilation Classic K702 also has a very realistic sense of space and airiness. The volume and texture of the low frequency dive far exceeds that of the K240DF and overshadows that of the Q701.
But the vocals are kind of a hard part of the K702 not too much, the vocal conjunctions are far away and not as rich in emotion as the Q701.
K240DF
The K240DF sounded accurate and the soundstage, while not as large as the 2 headphones above, was most comfortable and natural. The 240DF has a thicker midrange, with accurate and clear vocals. The small compilation of classics is very tasteful.
The downside is that there is less low frequency volume and the high frequencies are also slightly darker compared to the first two. But the biggest thing about these headphones is the naturalness and authenticity. Not bad for the most retained studio monitor of the year!
conclude
While all are professional use headphones, all three have good HIFI-ness, especially the Q701 and K702. Q701 more emphasis on ease of pushing, which makes even without too good front-end, but also able to listen to Q701 very well, which allows users of headphones have a good value for money, a better discrete sound card, you can push the Q701 tiger, which makes the K701, K601, K501 these headphones is unimaginable. In contrast the K702, although a standalone sound card with accompanying equipment can also make her sound a bit better. But play with caution without a very good front end.
Although the Q701 is better pushed, he is after all a big headset, the source that serves her can not be too bad, because good headphones can clearly reflect the shortcomings of the front end. Therefore, I still recommend that children who buy the Q701 use as good a front end as possible to make the best use of her strength.
Talking about pop music
In the test, I deliberately tried some popular songs: "Love for Sale", "Above the Moon", "Ningxia", etc
The Q701 is also spot on for pop songs, as there is a large amount of low end, and the volume in the low end of these songs can be described as absolutely awesome, with a very good sense of ambience. The limitations of recording pop music itself, though, also limit the Q701's play. The K702 & K240DF, on the other hand, are less suited to this type of music.
Also on K701
Since my friend next to me doesn't have a K701 on hand, there's no way to compare them under the same platform. But the K701 has been dabbled with a few times at jaben and taken down by an ear each time. The feeling is: meaty, sticky, and stained. In short, it's just unnatural and uncomfortable.
But I've heard that the various versions of the K701 are different, and each individual of the same version is different. Probably my bad luck. The K701 just doesn't make me love it.
