OPPO Enco X Review: good and competitive True Wireless earbuds in 2021

Oppo Enco X

Oppo, a Chinese manufacturer, is known for its smartphones, but has also been specializing in audio solutions for several years. Among these solutions we have the Oppo Enco Xnoteworthy, True Wireless Bluetooth headsets or earbuds.

They have active noise cancellation, cost approximately € 179 in UK and their premise is identical to that of Apple’s AirPods Pro, a product where they are inspired by design and some of the attributes. They are well built and the audio quality is already quite good.

Oppo Enco X first impressions and unboxing

Oppo Enco X

The box impresses with attention to detail, graphics and quality. It is accompanied by the Quick Start Manual, legal documentation, two pairs of extra pillows in sizes S and L, in addition to the short USB-A to USB-C cable for loading. All accessories and components are carefully packed in the box.

The presentation of the items is taken care of and meets the placement of this product on the market. It is an advanced audio solution.

Oppo Enco X Highlights

  • Active powerful noise cancellation (ANC)
  • Wireless charging
  • Good autonomy – up to 24 hours with the box – 4 hours (average) with earphones
  • Very satisfactory sound quality
  • Good build quality (IP54) and presentation


Active noise cancellation (ANC) is easily the biggest asset. They are lightweight and very comfortable to use, even for long periods thanks to their rounded shape. The stem is small, being relatively discreet.

It was by using these Bluetooth True Wireless earbuds during working hours with more people around that I discovered the capabilities of its ANC, adjustable on two levels, in addition to the Transparency Mode – and also being able to be disabled.

There are therefore four levels available to the user, adjustable from the Bluetooth Settings Menu on Oppo smartphones, or via the HeyMelody app, for other smartphone brands.


THE Transparency mode uses the three microphones present on the outside of the earbuds to amplify the surrounding sound. This allows the user to hear conversations better, in addition to being aware of the surroundings, recommended when walking on the street, for example.

The Enco X have low-latency Bluetooth connection, the Binaural Low-Latency Bluetooth that makes them (almost) usable for competitive games like PUBG Mobile. The delay is minimal, but it still manages to be noticeable.


For Enco X, Oppo has established a partnership with Dynaudio, Danish manufacturer of audio solutions founded in 1977, with the brand’s logo prominently displayed. The presence of this branding clearly visible in the earphones.

Another strong point is the wireless box charging. They support the Qi standard and this means that you can charge them on virtually all wireless chargers on the market.

With a charger wireless from Xiaomi I managed to load the box with the included earbuds, in about four hours, to four and a half hours. I felt that it was not easy to hit the correct position to start wireless charging, but that will also depend on each user’s charger.

For faster charging just plug the USB-C cable into the port on the bottom of the box. With a USB-C adapter, charging is faster. In two hours, in two and a half hours we managed to have a full charge in the box and earphones.


As a rule, I always put earbuds in the box when I wasn’t using them to always have some charge. Note that the box has an external LED that varies between green, yellow and red to indicate the battery status of the earbuds and the box itself.

Sound quality improves considerably when using the High Definition Codec (LHDC), although this is only available on some top smartphones. They also feature AAC codec, available in the settings of most smartphones.


It is worth noting that when activating the AAC codec, the battery life of each earbud is approximately four hours. By disabling this audio transmission option via Bluetooth in high quality, autonomy goes up to 5 hours, or even more.

Still regarding the autonomy, from the box we can expect 3 full charges of the earphones, possibly 4 depending on the type of use. These are good values ​​that also increase the portability and versatility of this product.

Using the Enco X earphones is comfortable


The earphones are relatively discreet, with a small stem and rounded main body. When used, this main body rests comfortably outside the ear, without causing fatigue when used for long periods.

This is an issue where I am particularly judicious. The minimum discomfort is enough to make me look for another solution. And, in this case, I can only say well about the Oppo Enco X. They are lightweight, relatively ergonomic and have extra cushions (2 pairs).

They do not cause discomfort during the 4 or more hours in which their autonomy allowed me to use them, therefore, they pass with distinction in this point.

Touch controls are not exactly intuitive


The design of the Oppo Enco X is very similar to that of the AirPods Pro and this turns out to be a positive point. They are beautiful True Wireless earbuds, well built in this shiny polycarbonate plastic and relatively discreet in the ear, with small stem.

However, as it is effectively small and slender, our fingers have a reduced area to touch. And when we play in a small area, we end up groping a little by chance.

This may not be important for some users, it was not a hindrance in my case, but for those who value touch controls, it is something to consider.


There are three types of controls – touch – main, as shown in the image above. Each of these are adjustable by the user, and can trigger different actions. The most useful and intuitive is to drag up or down to increase or decrease the volume, respectively.

By touching and holding the pressure for 1 second, we switch between ANC modes. By touching and holding the pressure for at least 3 seconds, we switch to another device – the earphones can connect to more than one device at the same time.

Audio quality is the most important point in earphones

Most of the time we use them we will be listening to music, so audio quality is the most important aspect when buying. Aspect in which the OPPO Enco X show the benefit of the partnership with DynaAudio.

The tuning, the balance of frequencies is very good. It is possible to discern various instruments, even on a reduced and closed sound stage. The bass is there, without drowning out and distorting the mids and trebles. Harmonization is well accomplished.

We are not going to compare Bluetooth True Wireless headsets with headphones of similar price, or higher. These are different realities, but I still had a good surprise with the audio quality in these Buetooth earbuds.


After testing and using similar solutions with Bluetooth earbuds, audio quality never seemed to be the strong point. With Enco X I felt greater sound fidelity. It is possible to listen to music with quality in wireless headsets.

Sound performance will also be perceived differently depending on the user’s favorite type of music. Through Spotify, also with the quality set to the maximum, this tends to be the playlist in high rotation.

In summary, you will be positively surprised by the level of detail that can be removed from this gadget that fits in your pocket. They are an extremely versatile solution for listening to music anywhere, or for making phone calls.

The quality of phone calls is excellent


Equipped with three external microphones, the Oppo Enco X allows you to speak clearly and hear well who is on the other side. The ambient noise is reduced so as not to cause distractions and we hear the other person perfectly. On the other hand, the feedback is also positive, even when the wind hits the earphones. There, we already have some distortion, but at tolerable levels.

For anyone planning to answer calls, or like to talk in this hands-free mode, this is a good solution. Clear voices, with good volume and definition, being easy to use.

Synchronization is as simple as opening the box


With the Bluetooth connection active on the phone just open the Oppo Enco X box and the following window will appear – image above. This on Oppo smartphones, or other devices that have already installed the HeyMelody application, for control.

Oppo Enco X manage quickly if they are paired with multiple devices and will know which one is playing audio. In that case, they immediately connect to the source that is sending the signal. They work without fail at this point.

Stable Bluetooth connection between smartphones and computers


Synchronization is very fast, both on computers and smartphones. This was another aspect that surprised me about Bluetooth headsets, an area where others are easily shuffled.

The Bluetooth connection to the smartphone never failed, or fell by itself, without also taking me too far from the source. They are great earphones to use, with no worries about more calls.

In case we need to pair the earphones with another device we have a physical button (unique) on the earphone box.

Conclusion: they are excellent Bluetooth earbuds, not perfect


The only drawback is touch controls. The result of a small area to touch the stem of the earphones and a limited range of options for actions – we have four types of touch with some possible behaviors. This is the only obvious imperfection of the Oppo Enco X.

The audio quality it was a good surprise. The construction quality is very good, with metal permeating the box and good quality plastic, shiny and with a touch of elegance throughout the product. Have IP54 certification.

They are extremely versatile and in this format – Bluetooth earbuds – the active noise cancellation is really effective. Autonomy is slightly above average – between 4 to 5 hours – and wireless charging is a good addition.

They are very good for answering calls and support good codecs for transmitting audio via Bluetooth. It is a really successful product that is placed, precisely, in the segment premium of Bleutooth True Wireless headsets.

Oppo Enco X are available in stores in UK at a recommended price of € 179, or through Amazon.ES from 161.99 euros. They are an excellent alternative to AirPods Pro and considerably more affordable.
