At present, there are many brands involved in the IoT ecological layout in the market, but among them, there are very few brands that really focus on the acoustic level. Most brands emphasize its tool attributes in smart audio-visual products, while ignoring its sound core. OPPO, as an early manufacturer engaged in the development of Blu-ray players and audio equipment, has not forgotten its original dedication to sound for smart devices in the IoT ecosystem. From the series of TWS products launched before, OPPO’s control over sound quality Far better than other brands. The most eye-catching is OPPO Enoc W51. The extremely high cost performance basically makes other true wireless headphones at the same price boring, sweeping the market in one fell swoop.
OPPO’s construction of the IoT ecosystem will certainly not stop there. The more high-end OPPO Enco X is officially launched. It not only has the dual blessing of Dynaudio joint tuning and DBEE 3.0 acoustic system, but also active noise reduction and wireless charging at the functional level. No shortage. Of course, OPPO Enco X is not only a high-quality noise reduction true wireless earphones, but also one of the important entrances to the OPPO IoT ecosystem. Through the control and empowerment of sound, OPPO allows users to seamlessly switch smart scenes with the help of headphones , To achieve real-time control and experience of the interconnection of smart devices.
After getting along for a while, I want to share with you my views on this strategic product.
▎Classic continuation, excellent texture
For OPPO, most consumers nowadays should remember its brand tone of “pursuing aesthetics”, and the products launched in recent years also have good appearance performance.
As a high-end flagship true wireless earphones product, the overall texture of the OPPO Enco X earphones is quite good. The outer side of the charging box is decorated with a metal frame, and the Dynaudio Logo on the back also highlights the sound quality attributes of this product. It has to be said that the true wireless earphoness launched by several mobile phone brands have achieved a good level of product texture.
Compared with OPPO Enco W51, OPPO Enco X adopts the structure of earplugs upright. It is very convenient to open the charging case cover with one hand, and the damping is also very good, not loose or tight. The earplug part adopts the current common handle design, the earplug handle is thin and short, and a special diaphragm is used on the outside, which will have a dazzling light and shadow effect under sunlight, which is quite individual.
Like many other in-ear true wireless headphones, OPPO Enco X also provides earplugs of different sizes, and in order to ensure that users can choose the most suitable size, there is also a “fitness test” function in the software. A special audio frequency is used to judge the leakage situation, so as to ensure that the effect of active noise reduction is at the best level.
The quick control of OPPO Enco X is touch type, and the operation area is outside the earplug handle. Clicking and sliding correspond to different functions, which can also be set freely in the software. Basically, the functions used in daily life can be covered, such as volume adjustment, Switch songs, switch the noise reduction mode, etc. It should be noted that the noise reduction mode switch of OPPO Enco X only supports two modes, the default is strong noise reduction and transparent, if you need to change to weak noise reduction, you need to Make adjustments in the settings.
It seems that the software settings have been mentioned many times above, and this is also an aspect of the OPPO Enco X earphones experience. Mobile phones that support ColorOS 7.0 or above can directly set up OPPO Enco X in the Bluetooth interface. For other Android models, you need to download an App called “Huanlu”, which is not currently supported by iOS. In addition, I still recommend using OPPO mobile phones to connect to OPPO Enco X. On the one hand, the delay rate will be better, with a minimum of 94ms. On the other hand, the user experience level will be more mature, such as fast support. Pairing and other functions, and when it comes to the software settings, the interface design of the “Huanlu” App for non-OPPO models is a bit casual, unlike OPPO’s official software development level. I hope it can be improved in subsequent version upgrades.
In general, the overall product texture and experience of OPPO Enco X are quite good. Compared with OPPO Enco W51, it has improved many experience-level loopholes.
▎Good noise reduction, stable connection
The OPPO Enco X earphones uses the BES2500 dual-core digital Bluetooth noise reduction chip specially customized to Hengxuan Technology to realize the active noise reduction function, which is better than the direct use of the integrated function of the Bluetooth chip. For this feature, I also specifically selected four scenarios to test the experience specifically, and used AirPods Pro as a reference product to see how OPPO Enco X actually performed:
❶ An airplane scene with a child sitting next to him
OPPO Enco X has a very good attenuation effect against the low-frequency noise of aircraft engine roar, and it is not weak in actual comparison with AirPods Pro. Both basically have close noise reduction levels in this frequency band, and both can make people disturbing. The aircraft noise is reduced to a feeling similar to the air outlet of a hotel, and with light music, it can basically meet the needs of daily business trips. However, this time I was testing with a child sitting next to me. This is basically a “hell-level” test difficulty for many noise-canceling earphones products. Compared with AirPods Pro, OPPO Enco X is more difficult for mid-frequency noise. The attenuation will be slightly better, and the human voice will appear to be turned into the ear through a door, but after all, it will not be able to match the sharp high-frequency noise attack of children. In this kind of noise environment, it is estimated that only head-mounted Noise-canceling headphones can come in handy.
❷ Noisy subway car scene
Although many people like to use airplane scenes to test noise reduction headphones, in my opinion, the noise environment of subway cars is more suitable for testing the performance level of noise reduction headphones. The noise of subway operation, the noise of crowd discussion, and the disturbing noise of mobile phones. This kind of complex noise environment requires a lot of algorithmic accumulation for a noise reduction earphones. Compared with AirPods Pro, the noise reduction effect of OPPO Enco X is more direct for noise processing, and the resulting weakness is more obvious, but the disadvantage is that the ear pressure is not as comfortable as the AirPods Pro, and it will be slightly oppressive Feeling, but the experience has little effect, and the music is basically no sense at the beginning.
❸ The cross street scene in the urban area
The cross street intersection in the urban area is not only a good place to test the noise reduction effect, but also an excellent place to test the stability of the true wireless earphones connection. The OPPO Enco X earphones still has a good noise reduction effect against the tire noise of road traffic. After wearing it, I can hardly feel the noise of the vehicle. And I stood at the crossroad for a few minutes without any connection problems. The stability is OK. Guarantee. In addition, I found that OPPO Enco X’s control of wind noise is quite good. Even in the strong noise reduction mode, the wind noise of OPPO Enco X is not particularly obvious. It is in the acceptable range. If you are particularly If you care about wind noise, you can switch to the weak noise reduction mode or transparent mode of OPPO Enco X to reduce the impact of wind noise.
❹ Indoor scenes playing light music
Among the four test scenarios, only this scenario has the lowest noise decibel, but it is precisely this relatively comfortable indoor environment that is the most common use scenario for most people. I personally recommend that you turn on the weak noise reduction mode indoors, the ear pressure will be reduced, and the low-decibel noise indoors is also sufficient, taking into account the comfort and tranquility. In this environment, I can also get a glimpse of the noise reduction style of OPPO Enco X earphones. Similar to the previous OPPO Enco W51 earbuds, OPPO’s noise reduction algorithm is very direct. There is a way to directly add a few layers of glass between the sound and your ears. The environment noise is weakened, and the distance between the surrounding voices is extended, as if to pull you out of it, the technique is very simple and neat. As for the transparent mode, although it does not achieve the almost-nothing “monster-level” level like AirPods Pro, the overall performance is enough to satisfy me. The surrounding sound is not excessively distorted due to algorithm processing, but it is only in weakening the earplugs. If you haven’t done it to the extreme, you can still feel listening to the sound with your ears blocked.
In fact, we can basically see from the above four scenes that OPPO Enco X earphones perform very well in terms of noise reduction performance. Even in the face of AirPods Pro, which sells for more than twice the price, they are not weak in some scenarios. .
Of course, all noise-reducing true wireless headphones have a little problem more or less at present. This is a problem that everyone is facing at this stage. For example, AirPods Pro will disconnect from time to time or appear abnormal when connected. Happening. OPPO Enco X headphones also have similar problems. In actual tests, it is found that the noise reduction state of OPPO Enco X in strong noise reduction mode sometimes becomes unstable. This instability is a bit similar to the feeling of dynamic adjustment. I can perceive the change in noise reduction intensity. It will not last long and will return to normal in a few seconds. Although it has no major impact on the experience, I still hope that OPPO engineers can improve it through OTA software upgrades. Experience details are also very important.
▎Dynaudio tuning, high quality low frequency
Although OPPO Enco X is a noise reduction true wireless earphones, its most prominent feature is actually the sound quality level.
The structure of the sound unit of the OPPO Enco X is very special. It adopts a dual-unit coaxial design, consisting of a superconducting magnetic planar diaphragm unit and a three-layer composite diaphragm moving coil unit. The former is responsible for the high frequency part, and the latter is Responsible for the middle and low frequencies, the acoustic system OPPO calls it “DBEE 3.0 Dynamically Balanced Sound Engine”. There are not many true wireless earphones on the market that use coaxial design, and many of the coaxial design earplugs use a dual unit design of moving iron and moving coil, equipped with a flat diaphragm and moving coil coaxial design. There should be only OPPO Enco X for wireless headphones.
The unique acoustic structure makes the sound of OPPO Enco X really interesting. The low frequency can come down and the high frequency can go up. Dynaudio’s tuning process is also quite natural in connection. Especially worth mentioning is the low frequency part of OPPO Enco X, which is more solid than many true wireless earphones, and it can be retracted and placed quite freely. In terms of timbre style alone, I personally think that OPPO Enco X has a strong popular taste. This style is derived from its strong and powerful low-frequency texture and warm atmosphere. It follows the sound-resistant route in the sense of hearing.
However, even so, the sound of OPPO Enco X headphones is not a balanced type. The low frequency and high frequency will be more prominent than the mid-frequency part, which indirectly leads to the improvement of OPPO Enco X’s vocal processing. Slightly far away, and the voice is brighter, a little irritating, especially when listening to some Japanese female voices.
Due to the use of LHDC audio coding, OPPO Enco X can also guarantee a certain level of sound quality under wireless connection. Although I personally do not think that high bit rate wireless transmission is a necessary condition for good sound, at least it can have a better sound foundation. For the rich details, OPPO Enco X gave me the same sense of hearing. The sound performance is quite clean, especially when listening to some lossless music, you can clearly perceive the difference from streaming music. If you are concerned about the sound quality of true wireless headphones, then it is recommended that you choose a device that supports LHDC to connect to OPPO Enco X. Currently, OPPO models that support this encoding technology include Find X2, Find X2 Pro, Reno 4 SE, A72 5G Wait, other models need subsequent OTA updates to be supported.
Of course, even with the AAC encoding connection, I don’t think the sound of OPPO Enco X is degraded. For wireless audio products with mature tuning, no matter which audio encoding transmission is used, the listening level is OK.
Among the many true wireless earphones I have heard, OPPO Enco X is indeed a product of the first echelon. I am impressed by its high-quality low frequency. It is rare that this kind of sound performance can appear in a true wireless earphone. According to OPPO’s official survey, today’s consumers are most concerned about the sound quality of true wireless headphones, and OPPO Enco X is a way for OPPO to respond to consumer expectations.
▎Building an ecology, a comprehensive choice
OPPO’s strategic deployment of IoT will focus on three scenarios: personal entertainment, sports and health, and home scenarios. The recently released OPPO Enco X, OPPO Watch RX and OPPO Smart TV series are the ecological entrances in these scenarios.
As a representative of personal entertainment, OPPO Enco X is more than just a true wireless earphones. It shoulders an important part of the OPPO ecosystem, such as the entertainment switch from mobile phones to TV, the identity switch from earphoness to smart homes, and more Function switching from entertainment to health, etc. Do you think OPPO just wants to make a full-featured noise reduction true wireless earphones? No, they see farther, and the products are more abundant.
Regardless of the product level or the ecological level, the significance of OPPO Enco X to the market is not to be glimpsed. I once said that OPPO Enco W51 is basically the only option at the same price, and OPPO Enco X, which is priced at $179, is quite strong at the same price. The competitor is very worth recommending to users of Android phones.
As the title says, OPPO Enco X is not only a full-featured, almost no shortcoming noise reduction true wireless earphones, it is also OPPO’s full ambition for the IoT ecosystem. True wireless earphoness have undergone three changes from the beginning to the present. The first time greatly improved the connection stability, the second time the wireless charging function was added, and the third time was the addition of active noise reduction technology, and this fourth change Personal guess is probably the use of intelligent scenarios.
Obviously, this is the direction OPPO Enco X is heading.
