Jess Image S4 in-ear headphones evaluation

Probably because of the second-generation listing, Klipsch made a big adjustment to the S4 price, the current price is 299 yuan, and once sold at more than 500. This headset sells well, and there is a metal storage box, plus The price fell into sensitive areas, and the Klipsch brand made the headphones that came out in 2009 more attractive. In fact, the S4 is already the most sold headset in Klipsch.

S4 is made of plastic material, silver and black color matching [also silver and white], silver part plating treatment, black part is sprayed with high-gloss coating, so the ear shell looks sparkling, slightly publicized.

The acoustic structure is closed, and the in-ear headphones rarely have an open design. According to the e-commerce sales page, the S4 speaker uses a double neodymium design. What is neodymium? The crucible is a metal that is more active than sodium. It can't be used in magnet alloys, so this is a wrong way to write. The real material is neodymium iron boron magnet, a magnet commonly used in tweeters and earphone speakers. The dual magnet design is mainly to provide a better diaphragm. Control, in theory, will make the sound more stable.

The speaker has a diameter of 8.5 mm, which is not a large diameter. For this reason, the S4 is designed to be smaller and the weight is controlled. In terms of wearing, the comfort is better. Wen Xuanzhong has always emphasized the HiFi sound quality. The award, beautifully worded, mentions that the speaker has a very wide frequency range, but this is out of touch with the sense of hearing, and the S4's obvious high frequency is bleak, which we will mention later.

Designed for Walkman devices, the S4 has an impedance of 18 ohms and a sensitivity of 110 dB. The adaptability should be very wide, but too high sensitivity encounters noise floor, which may be exaggerated, but it can be used with common high-quality players. For the convenience of storage, S4 comes with a white metal storage box, which adds value and is more convenient to use.

S4 is not very good, the sound is mellow, and it took 50 hours to start to improve. In the process of listening, we use Apple Nano 6, vivo Xplay 3S and other audio equipment.

Low-frequency performance: S4 is not a balanced earplug. Its low-frequency performance is very prominent. It can even be described as exaggerated. The highlight is not only the frequency response, but its low-frequency sense is obviously high-profile design, but it does not lose too much strength and maintains the impact. There is even some flexibility, so the low frequency doesn't sound soft and weak. The low frequency is very flattering. If you have a preference for this low frequency, you will soon like it. A variety of styles, especially when enjoying some percussion, will feel enjoyable, strong but not rushing, although the details are lost, but the whole atmosphere is very good, the ability to create low-frequency atmosphere is the most prominent feature of S4, this feature is There will be an overwhelming advantage in the performance of some rock music electronic music. Performance "Bjork-All is Full of Love", "Essay - Ghost Taigu - Sogaku", "Essay - Hans Zimmer-The Rock.Hummell Gets The Rockets 》 This kind of music also has a good performance, at this price is rare. Although S4 is really easy to drive, but on the more powerful sound source equipment, the low frequency can perform better. , performance is low The frequency is slightly thinner, but the intensity control is better, and the low frequency layering is better.

High-frequency performance: contrary to the characteristics of low-frequency highlights, the high frequency of S4 is obviously dark, which we think is too dark. This leads to the lack of high-frequency details, which affects the judgment of the overall resolution. More important Yes, this kind of obviously dark high frequency, listening to a lot of music, especially the more low-frequency songs, there will be a feeling of boring, this feeling gives people a negative emotional impact. Do not mention extension, S4 does not It is suitable for talking about this. As for all kinds of strings, for S4, it is just a make-up. The advantage of the darker high frequency is that listening to metal acoustic instruments is not so tired. If it is improved, it is improved. The evidence, we do not agree.

Intermediate frequency performance: What is the performance of the S4's intermediate frequency under the obvious low frequency and obvious dark high frequency pinch? The medium frequency of the S4 is somewhat picky. Under the influence of high frequency, its bright style vocal performance is obviously affected. The performance is not enough brightness, old-fashioned, not enough spirit, while the male and female mid-bass are obviously better, warm and heavy, and the human flavor is added. The effect of low frequency on the intermediate frequency is also great. If you appreciate the vocals of the near-singing, It is found that the mid-frequency of S4 has a little enchanting warm color, but with the sound of low-frequency instruments, the frequency is gradually affected, blurred, drowned and so on.

The advantages and disadvantages of S4 are outstanding. The bass lovers will give praise, the high frequency will definitely give bad reviews, the biased tuning makes S4 become very picky, or listen to the lyrics of the lyrics, or listen. Listening to the small composing vocals, if the compilation is too big, the whole will appear a bit messy. If you want Wanjin oil to be wild, S4 is not suitable. Under its low frequency boost, the atmosphere is very characteristic, the sound field can expand the width, but The height is not enough, it is flat, and it has a good image. Under the small compilation, it can also separate the orientation of the instrument. It is very characteristic and not comprehensive. This is our evaluation of S4.
