Anyone who has played headphones should know Sennheiser. Sennheiser has created many classic headphones. In addition to the king of the headphones ORPHEUS, HD800, IE800, IE80, which are familiar to enthusiasts, have recently ushered in corresponding upgrades. The more comprehensive sound experience of the HD800S has been recognized by the majority of enthusiasts. The IE80S, which was unveiled at IFA in September this year, has gradually become a new hot spot. It is an update of the classic model IE80.
In fact, I was still looking forward to getting IE80S. After six years or so, the changes in the earphone market can be said to be earth-shaking. Can the newly launched IE80S still reproduce the glory of the year?
The simplicity of IE80S packaging has changed a lot from the previous transparent style. This time IE80S is featuring a new and elegant design and a professional sound experience. Although I don't understand some German texts on the outer packaging, I can still read some parameters about the parameters under the back. In addition, this time IE80S also comes with a COMPLY memory sponge cover, which is also the C set commonly referred to in China, and is marked on the wrapping paper.
This time, the accessories of IE80S are not as elegant as the previous IE80, but they are fuss about practicality. A portable cloth bag can more easily carry the IE80S to the user's side anytime, anywhere. In addition to the carrying case, there are three pairs of different sizes of silicone sleeves, three pairs of small and different double layer silicone sleeves, three pairs of different sizes of C sets, and a pair of earers, a tuning stick and a manual.
The appearance of IE80S is similar to that of IE8/IE80, but it is not the same. The left and right lines are marked with red on the right channel. This color is a common recognition method. The IE8/IE80 has a flat surface treatment on the back, and the IE80S has a slightly protruding part in the back cavity. This protruding part makes the earplug look more layered and more three-dimensional. At the same time, Sennheiser also designed its own logo and IE8 series of tuning holes, the surface of the raised part still uses the IE80 brushed stainless steel metal surface design, as if in front of the IE80 design. The raised portion of the cavity portion also provides better protection of the core component of the earbud unit.
There is such an imprint on each cavity of the IE80S. Below is the model number. The above number is not very clear. The numbers on the left and right sides of the cavity are the same. There are left and right imprints on the cavity, and the filter mesh of the guide hole is made of a metal mesh cover, which is very dense. IE80S uses the unique change mode of Sennheiser IE8/80 series. There are many upgrade lines designed for IE8 and IE80 on the market. With the arrival of the balanced port era, I don’t know whether the official accessories of Sennheiser are Will follow up.
The IE80S inherits the design of the IE8/IE80 series of adjustable low frequency air switches, which are achieved by changing the air flow inside the headphones. When it is adjusted to the minimum scale (the factory default is this scale), the vent hole is closed at this time, and the air pressure inside the earplug cavity cannot enter more air balance chamber. The vibration of the diaphragm greatly affects the low frequency due to the agitation of the gas. The amount. So according to this principle, IE80S can achieve a variety of different low-frequency effects by adjusting this low-frequency air switch. The longer the scale is, the more the low-frequency air switch opens, and the more air that enters, the higher the amount of low-frequency.
The IE80S line is relatively thick, reliable, and the wire is slightly harder. It is estimated that it will be softer for a while. The wire stalk handle has a small similar serial number. In the part of the plug changed from the original bend to the straight insert, the whole wire can be used with the ear-winding device attached to the accessory, which feels a lot younger and more fashionable.
Overall, IE80S still maintains many excellent designs from the previous ones, and on this basis, many improvements have been made. The change on the back side and the red mark on the wire have become the biggest difference between the IE80S and the previous IE80. The more layered cavity shell and the convenient wire-to-user connection are all signs that the IE80S is more mature in design. IE80S pursues a more stylish and mainstream look, no longer like a purely industrial product.
IE80S In order to achieve the coordination of the compact in-ear headphones and dynamic unit sound quality experience, IE80S dynamic range system has a wide range of sound, high accuracy of reproduction and good sound clarity. In order to achieve the highest level of sound quality in a compact cavity, the IE80S has been re-established on the original earbuds and units via nearly six years of development and sound tuning by Sennheiser's professional engineers and acoustic experts in Germany. Design or improvement. To quote the official, it is "to challenge the quality limit of Hi-END in-ear headphones again." The IE80S has a frequency response range of 10-20 kHz, a sensitivity of 116 dB, and an impedance of 16 Ω. The official also emphasizes that the passive noise reduction of the earphone can reach 26 dB.
The opening of IE80S was a little disappointing. The new plug was not as ideal when it was used. The first time it was heard, it would be scared by the low-frequency sense of the face. The problem IE80S before IE80 still exists. Because it is a new earplug, especially the pure dynamic earplugs need a slap to have a more realistic sound experience. I kept turning on the computer to IE80S day and night, and now this IE80S has gone through more than 120 hours of downtime.
The style of IE80S is very popular with Sennheiser IE8/IE80 series. It highlights the high-frequency resolution and low-frequency volume and dive. The position of the instrument and vocals on the intermediate frequency is relatively prominent, and the sound field is complete. These are all perfect inheritance and repair on IE80S. Here we used the MR1 player and the iPhone 8 Plus+ patch cord to listen to the sound of the IE80S.
First of all, IE80S has achieved the unique looseness and natural feeling of Sennheiser in the extremely high frequency part. Unlike the sound of many earphones nowadays, IE80S will not let you feel the harshness of the metal texture. The relatively high-frequency style of IE80S is also extended to the high-frequency part. The high-frequency of IE80S is relatively slack, and there is still no burr when using a player with high resolution and high-frequency relative stimulation. IE80S has the advantages of some traditional earplugs, that is, in the case of large dynamics, the high-frequency resolution is excellent. At the same time, the high-frequency transient of IE80S is also very good. This is a point that many moving earplugs are more difficult to achieve. .
The IF of the IE80S is slack and natural. The IF of the IE80S is relatively full and very tensiony. However, the overall soft style makes it an illusion that people are vocal in the appreciation of some vocal music. This time, the IF of the IE80S can better cope with some big dynamic music. The rich level of the intermediate frequency and the high resolution make the level and sound between the instrument and the instrument very delicate. This also makes the IE80S face all kinds of music. And OST music has more advantages. The vocal position of the IE80S is different from that of many earphones. It is not attached to the ear, and it is sufficiently open to the level of the instrument to have a very good distinction.
The low frequency of IE80S has been greatly improved after the downtime, the sound will be much more refined, the low-frequency dive and volume advantage is still very obvious, but the low-frequency resolution is still not ideal, the layering still can not be compared with the high-end earplugs on the market. ratio. In the face of large dynamic music with low transient speed requirements, the advantages of IE80S are very obvious. The relatively soft, low-frequency low-frequency will be worse on mobile phones with relatively small thrust, and even the basic control will be lost. Under the high quality and better thrust player, the low frequency of IE80S will be much more refined.
The IE80S is a very good single-unit dynamic earplug. It is a very good driver for the mainstream smartphone, and the audio solution of the current mainstream smartphone can promote IE80S. The overall resolution of the IE80S is still good, and the low-frequency resolution is slightly insufficient. The sound field of IE80S is very good, loose, natural and has excellent sound image. IE80S can also achieve more low-frequency sense by adjusting the bass air switch. In fact, I think that one file is enough, so other gears are not tested.
The IE80S offers two different sets of earbuds in the double and C sets. The double-sleeve makes the overall style of the sound more slender, and the vocals are more prominent, making the style of IE80S more neutral. The C set makes the low-frequency image solid, the high-frequency resolution and information volume are reduced, and it will become more exciting when listening to some rhythmic music.
IE80S is relatively omnivorous, and can listen to a wide range of music, especially good at dynamic OST, the new century, all kinds of music, and the ordinary pop music, especially those hip-hop and rap that are more obvious. Music and the most popular electronic music now have a good sound experience.
As mentioned at the beginning of this article, the earphone market has undergone earth-shaking changes. The quality of domestic earplugs has sprung up, and some emerging brands of the dark horse have frequently entered this market, while at the same time, the market space left for veteran manufacturers has become more and more limited. . The IE80S official positioning is high-end portable in-ear earphones, which combines the portable size and excellent sound and professional functions into the IE80S, and balances between them.
IE80S has greatly improved the two products of IE8/IE80, and it has become a highly completed product. This is the maverick of the traditional series of Sennheiser products. In the face of the current market changes, IE80S is still full of "de taste" sound is still very competitive. As for the lack of balanced interface, the lack of Hi-Res playback capability can only expect the performance of the more high-end IE800S.
