Multiple units, mixed architecture, even wire are armed to the teeth today, but also with a "flagship of the same model" dynamic unit to dare to come out of the world, should be considered by everyone to be "ignorant fearless", right? However, sennheiser IE600 in-ear headphones (hereinafter referred to as IE600), which is what I see you in the PConline evaluation room today, is what I do. Combined with the price point, I believe everyone wants to know whether the IE600 with a 7mm TrueResponse dynamic unit alone can have the capital of the outstanding.
Sennheiser IE600 technology and external analysis
If you pay attention to the IE900 previously released by Sennheiser, then you should be familiar with the saying "TrueResponse dynamic unit". After consulting the official Sennheiser website, we found that although the Sennheiser IE600 and IE900 use the same shape design, they have very different processes and acoustic structures.
First, let's focus on the process of creating the entire cavity. Previously, the IE900's unibody aluminum cavity, which was precision milled by a five-axis CNC machine tool, was enough to make people sigh Sennheiser's ingenuity. Coming to IE600, Sennheiser is still striving for excellence in cavity manufacturing, this time using 3D printing technology based on metal powders.
If you are interested in the mechanical manufacturing process, then the answer given by Sennheiser should be no stranger. Compared with common 3D printing technologies, Sennheiser calls this 3D printing process Heraeus amorphous metal technology. Shells manufactured by this technology are able to achieve zirconium alloy hardness and flexural strength three times that of high-performance steels. At the same time, this technology prevents the formation of metal crystals through impact freezing technology, resulting in a glossy smooth surface with extraordinary corrosion resistance and scratch resistance. To put it bluntly, the cavity of IE600 is really "hard and rigid", but the feel and ear touch still make people feel comfortable.
The Amorphous Metal Chamber of the IE600 was produced in Germany, and thanks to the joint efforts of computers and human hands, the excellent physical properties and the unique style of the smooth cavity were finally taken into account. This is not only for the sake of appearance, but also for the sake of Sennheiser's sound cavity design to achieve his goals. The IE 600 is equipped with D2CA dual resonator technology to capture and attenuate masking frequencies in similar frequency bands to ensure sound resolution. Although it does not sound as powerful as the ultra-broadband three-cavity sound absorber (X3R) used in IE900, manufacturers who have the ability to control the design of the sound cavity are indeed worthy of everyone's respect and expectation.
After looking at the cavity process and sound cavity technology, let's take a look at what accessories Sennheiser has included for the IE600. In the package we can find a storage box, which includes a 3.5mm unbalanced interface and a 4.4mm balanced interface of the wire. Both wires have earhooks, like it or not is a matter of opinion, our group of editors have glasses members said that the earhook design can just get stuck in the spectacle legs, wearing is still quite stable. In addition, IE600 is also the use of Fidelity Plus MMCX interface, to upgrade the cable for IE600, it is best to ask the merchant can not support.
In addition to the wire, the box also has two kinds of ear tips, silicone and memory foam, both of which are available in three sizes, large, medium and small, to suit different ear shapes. Speaking of ear tips, let's talk about what it takes to wear them before we start sharing the audition experience.
When we evaluated IE900 before, we mentioned that even if it is an "old driver", it is still necessary to find an angle when wearing it. This situation also exists in IE600. Through the appropriate size of the silicone sleeve, to achieve a "seemingly incomplete" point, just stuck in that position, you can enjoy the sound of achieving the design goal, and have a certain degree of wearing stability. On the other hand, if you feel that the voice is strange, or the wear is unstable, then the teenager still needs to find an angle
Sennheiser IE600 subjective audition and summary
Now that "sound to the design goal" is mentioned, how exactly does the Sennheiser IE600 in-ear headphones perform? To be honest, when we first started, we were a little surprised. When we experienced IE900 before, it felt like condensing HD800 in it. The IE600 that has just opened the sound makes us feel that this is the sound that is adjusted based on the IE900.
Clear to aggressive line sense, clean frightening sense of hierarchy and transients, diving deep enough but the sense of volume is not much low frequency, although the sense of boundaries is strong but has a longitudinal performance of the sound field, IE600 This initial sound experience ah, let people feel that this is not Senhai at all, but more cater to the trend of young people like to listen to EDM/ACG nowadays.
However, the interesting thing about the dynamic headphones is that after experiencing the pot machine, the sound may have a relatively large change. After more than 50 hours of casserole, the IE600 also followed this normal. Compared with the first time to open the sound, the first thing that makes people feel the change is the performance of the low frequency.
The IE600 low frequency after the casserole machine has weakened the depth of diving, and there is no punch-to-flesh impact, it has become looser, and has a relatively diffuse overtone performance. Having said that, the low frequency of IE600 is not "hufi", and it is really good to hold it, which is a performance that can set off the atmosphere. Whether it's orchestral pop music or some classical music, the IE600's low-frequency performance provides a good sense of atmosphere without too strong an impact on the music as a whole. The texture of this low frequency means that IE600 is very confident to stand at the 4K price.
Due to the influence of the low frequency, the mid-frequency performance represented by the human voice is also relaxed and stretched. Listening to some slow pop music and tasting the performance of the singer, we can find that the singer's spitting expression is more rounded and comfortable, and there will be no "unclear wording" hufi state. Although the vocal density at this time is not very high, thanks to the sharpness of the vocal lines at the opening of the sound can be retained, the vocal performance of the IE600 can be both relaxed and appreciated, and can also be carefully considered.
From the perspective of medium and low frequency performance, the IE600, which is gradually stabilizing, is a warm and atmospheric sound, which means that its high-frequency performance will not be how gorgeous it is emphasized, or how strong the extensibility is. "Texture" is the purpose of the high frequency of IE600, and when listening to the string performance of the IE600 playback, we can even imagine the texture of the instrument with both hands. This kind of high-frequency performance that touches people's hearts through texture, combined with reasonable arrangement and high-quality recording, can really "poison" the listener coldly, making people fall in love with this headset more and more.
The huge contrast between the front and back of the cooker also makes us look at the performance of the IE600 - it is not so much based on the sound of the IE900, but rather a pop enhancement version of the HD650. Why? Compared with IE900, the soundstage of IE600 is indeed a circle smaller, and the sense of boundaries is relatively strong, but IE600 relies on its excellent longitudinal soundstage and high performance in in-ear headphones, combined with warm but not "hufi" layered expression, making people feel as if they are in a warm live performance occasion and want to gently swing their bodies with music.
summary
Why did we give this experience such a title? That's because in the past decade or so, Sennheiser's TWO product lines, HD/IE, which start with "6", will bring intoxicating pop performance. If you are reading the article long enough or have played with enough headphones, you may wish to review the performance of the HD600/IE6/IE60 to confirm whether it is in line with this observation.
With the passage of time, IE600 not only inherits the excellent pop performance of the "6" products, but also enhances the performance of sound lines and layering in response to the needs of the times, in line with the current trend of the world pop music scene mostly arranging music in a fusion way, and the recording quality is also constantly improving. If you always like the sound characteristics of dynamic headphones and want the quality performance not to be outdated, then the IE600 is a choice worth considering.
