In recent years, earphones have become the second battlefield after smart phones. Before that, hardware manufacturers such as Xiaomi Meizu launched earphones in succession. Later, celebrities such as Wang Feng and Jay Chou took part in them. The headphone industry has received unprecedented attention. As the only music hardware brand invested by Netease Cloud Music at present, Yinv IN-VOICE launched its first product IVOC-100 music headphones (hereinafter referred to as Yinv IVOC-100). Today, let's find out.

In view of the fact that IVOC-100 is similar to Sony's h.ear on series in design and positioning, the author has asked MDR-100A for comparison.

1： Appearance and workmanship

In appearance, Sony's MDR-100A uses bright colors to take a dynamic and lively route, while the IVOC-100 chooses a low-key and luxurious style. The khaki yellow we got is more like champagne gold than yellow.

The sound cavity design of IVOC-100 water drop type, together with the sexy metal single arm, is unique in shape and neat in details, highlighting the original texture of metal.

Sony MDR-100A adopts the traditional oval design without too much decoration, and the consistency of plastic and metal colors also highlights its superb production process.

In terms of wire material, high grade OFC oxygen free copper is used for audio voltage, and only one key is set to reduce the distortion and loss of audio signal. What the author appreciates more is that the plug is designed to prevent dragging, which is convenient for daily use.

Sony's headphone cable uses the design of noodle cable, which is not easy to entangle and is more convenient for users to store.

2： Wearing comfort

Here we can see that IVOC-100 can stretch and rotate nearly 180 degrees, which can adapt to different people. The inner side of the head beam is perforated to ensure breathability and comfort.

The leather part of the IVOC-100 earmuff is soft and comfortable, while the sponge filled part has good flexibility, and the performance is satisfactory.

The adaptive ergonomic design of IVOC-100 is very practical. It can be worn directly on the head and adjusted slightly. In fact, after wearing it, the sense of fit is self-evident, and the beautiful appearance is no pressure even on the street.

While the MDR-100A needs to adjust the head beam first during the wearing process, and it still needs to be adjusted after wearing to be more comfortable.

The earmuff MDR-100A performs well, the cortex feels full, and the sponge filled part has moderate elasticity, without any discomfort after wearing.

However, the MDR-100A benefits from its lighter weight, which makes it less oppressive to the head and more suitable for long-term wear.

3： Auditory perception test

In order to give full play to the strength of the earphones, the author has spent 150 hours on the two earphones, and the front end uses the iPhone 7 (equipped with a Lightning-3.5mm converter) with Netease Cloud Music as a reference. It should be noted that both IVOC-100 and MDR-100A are equipped with 40mm dynamic loops, and the frequency response ranges are 10Hz-5000Hz/5Hz-60000Hz respectively, It is beyond the 20-20000Hz range of human ear. The Hi end team of Yinv uses IR pulse response technology for tuning and is equipped with dynamic air damping technology; Sony, on the other hand, has adopted technologies such as diaphragm titanium coating and CCAW coil in tuning, both of which have made great efforts.

Overall impression:

IVOC-100 can be said to be a "toxic" earphone, which controls the voice in place, and is tuned to medium and high frequencies. The overall style is gentle oriented. This makes it easy for users to be attracted by the singer's voice when listening to songs without hearing fatigue due to being too aggressive. The overall standard is really good. The high frequency is relatively warm, and the medium and high frequency stretch is moderate. As a pair of headphones with a crowdfunding price of only 499 yuan, it is really hard to control the tri band. In contrast, MDR-100A is more like a partial college student. Its tuning style is more suitable for listening to rock, pop and other tracks. Its rich low-frequency and aggressive mid-frequency performance can give users a different listening experience.

High frequency performance:

In the high-frequency part, the author chose UNICORN by Hiroyuki Zeno as a well received small compilation track in recent years, which can well demonstrate the high-frequency quality of earphones.

As a closed earphone, the sound field of IVOC-100 still gives the author a lot of surprises. Although it is not comparable to the open earphone, it is commendable to be able to make the sound field so wide. The fast response speed in the transient response makes the control of IVOC-100 quite correct, while the MDR-100A is inferior in high frequency, It is easy to get out of control when pressing with a loud voice, resulting in obvious burr feeling. On the other hand, IVOC-100 benefits from the excellent pronunciation unit, which is very good in parsing. The exquisite details and good extension bring users a rich sense of hierarchy, while the MDR-100A is a bit "fuzzy".

Intermediate frequency performance:

In terms of intermediate frequency, the author chose Lin Junjie's Keyword. The right background music and Lin Junjie's unique singing are very suitable for testing the performance and analytical power of intermediate frequency.

Because IVOC-100 and MDR-100A are both closed design, their dynamic performance in IF is relatively limited. In terms of voice, IVOC-100 will be more attentive and full, with good connection between middle and high frequencies, balanced and delicate, while MDR-100A will be tighter and less relaxed. When listening to the voice, the author prefers IVOC-100, whose voice is very ear grabbing, and the user has a very good sense of substitution at once. However, the MDR-100A is more likely to make the user feel tired due to its slightly aggressive voice performance due to excessive sound pollution. In contrast, IVOC-100 is more durable and deserves praise.

Low frequency performance:

In the low-frequency part, the author chose Frankmusik's Wrecking Ball. The dynamic music style is very suitable for testing the low-frequency control of headphones.

In terms of low frequency, IVOC-100 and MDR-100A adopt two different calibration methods. In terms of low frequency, IVOC-100 tends to go from point to point, controlling both quality and quantity within a reasonable range. The transient is fast, and the sense of quantity is just right. Although the dive is shallow, the elasticity is still very correct. On the other hand, MDR-100A is a form of expression from fist to meat. Although it really feels at the beginning of listening, it does not control the amount of low frequency well. Often, one more frequency of low frequency will easily cause a blockbuster, and the elasticity is relatively loose. The most important thing is that its low frequency will also cover the medium and high frequency, causing loss of details. On the whole, the MDR-100A is more likely to create a refreshing atmosphere for users when listening to rock, pop and other tracks due to its low frequency sense of volume, while the IVOC-100 is more balanced.

4： Summary

In general, as one of the senior brands in the headphone industry, Sony's MDR-100A tuning style has more obvious tendencies and performance characteristics. For users who like rock and pop songs, the beautiful appearance of MDR-100A should impress many young people. The tuning method of IVOC-100 tri band balance and the tuning of partial monitoring allow it to take into account most of the music styles. The luxurious appearance and solid materials can create a good wearing feeling for users. With a crowdfunding price of only 499 yuan, the quality performance of IVOC-100 is really worth more than money, and it is fully capable of meeting the needs of first burning earphones, Musicians who have the desire to upgrade their sound quality may want to try it, or they may get unexpected surprises.
