Oppo continues its collaboration with Danish audio specialist Dynaudio, launching the second generation of its headphones True wireless Enco X that we tested and appreciated. The Enco X2, sold for around 200 euros, promise excellent sound quality and very effective noise reduction. promise kept?
In terms of design, the differences between the first and second generation of headphones are minimal. However, we do notice that the Enco X2’s stem is wider, as can be seen in the photo below.
This can be explained by a new control system that consists of pressing on the sides of the stem, as in Apple’s AirPods Pro. Oppo has also provided volume control by sliding your finger up or down, but this is only done on a specific part of the stem (see photo below).
The manufacturer’s aim is to avoid triggering a command by accidentally touching the most accessible side of the wand and also by pressing on the ear. On the other hand, it will be necessary to grip the headphones from above in order not to exert unintentional pressure, which often happened to us at the beginning of the test.
The Enco X2 benefit from the same very good comfort and support as the Enco X. They come with three pairs of ear tips but unfortunately are still not waterproof. On the other hand, they are sweat resistant (IP54 certification). In addition, the tips have an antibacterial treatment for better ear hygiene and a filter that prevents earwax from entering the headphones.
The noise reduction boosts the bass
Another similarity between Oppo’s two generations of headphones: the use of two speakers (one for the treble and one for the bass) to improve the sound quality. The Enco X2s are equipped with the classic AAC and SBC audio codecs, but also with the high-resolution LHDC codec, a competitor to Sony’s LDAC (see below).
Note that activating the active noise reduction (ANC) leads to an increase in the bass in the 50 Hz range, while the frequency response measurement shows a drop in the treble from 10,000 Hz.
It is indeed the impression to be listened to. The sound is very warm with good bass response but sometimes lacks clarity and brilliance. Fortunately, this problem can be easily compensated for by enabling the feature golden sound (golden sound in English) of the HeyMelody application (see below). The quality then becomes excellent, with a perfect reproduction of the soundstage.
More detailed sound is possible with the LHDC high-definition codec, but we only saw a slight improvement in quality. In addition, this codec requires a compatible smartphone, such as a model … Oppo. The sound quality is also good when making calls, even in noisy surroundings. In fact, the Enco X2 uses bone conduction sensors to distinguish your voice from ambient noise during a call.
Now we come to the active noise cancellation (ANC), which we tested on the train and subway. It’s effective, but falls a little short of what Bose’s excellent QuietComfort Earbuds offer.
In particular, we’ve seen slightly better voice reduction compared to the Enco Xs, but don’t expect to find yourself completely isolated from your neighbors in a cafe or coffee shop open space. Note that choosing the right size earbuds is crucial to benefit from good noise cancellation.
Noise reduction affects endurance
Has Oppo made any progress on the endurance of its headphones? The response is mixed. Without noise reduction, the Enco X2s achieve an excellent score of 9:28 according to our measurements, compared to 8:14 for the Enco X. However, this is marred a bit when you activate the ANC, which seems to use more energy than the second generation. We then go from 7:56 for the Enco X to just 5:49 for the Enco X2, an acceptable result but well below the average of our measurements (around seven hours). However, Oppo’s headphones last longer than Apple’s AirPods Pro (4:39 with ANC and 4:48 without ANC).
Oppo announces a total autonomy of 22 hours with the charging case. It even reaches 40 hours if you disable noise cancellation. We appreciate the reduced size of the case, which easily fits in the pocket, as well as the compatibility with the Qi wireless standard.
There is a small advantage over the Enco X, it is no longer necessary to turn the headphones before inserting them. In fact, in the first generation, the tips are positioned outwards in the housing. It’s a pity, however, that the status diode is placed inside and is therefore not visible when the lid is folded down.
Very interesting features in the app
While Apple insists on not providing an Android application to use its AirPods, Oppo is more open. The manufacturer offers the free HeyMelody app for iOS and Android. It has two very useful features: a headphone fit test to check you have the right size eartip and a hearing test. In about three minutes, it determines your ideal audio profile (golden sound) by giving you a short audiogram. We actually noticed a significant improvement in sound quality after the test.
A real disappointment, however, is the equalizer, which only offers four presets. We would have liked to have been able to manually tune the frequencies.
In addition, while browsing the app, we found an option that activates the dual connection, that is, the multipoint Bluetooth. This allowed us to easily switch from an Android smartphone to an iPhone without having to disconnect and then reconnect.
The app also has a feature to customize the commands when you press the bars once, twice, or three times. The long press is reserved for noise cancellation, but a vertical swipe on the stalk gives you two choices: adjust the volume or change tracks.

Finally, the HeyMelody application allows you to enable or disable noise reduction but also control its intensity. You have three levels of adjustment (Max, Moderate, Soft) but also an intelligent mode. The amount of reduction then takes into account the intensity of the ambient noise, but it sometimes takes a few seconds for the adjustment to take place.
The verdict of the test
The Enco X2 are a very good alternative to Apple’s AirPods Pro, even on iOS. We were won over by the comfort, sound quality and effectiveness of the active noise cancellation.
On the other hand, it is a pity that the autonomy with active ANC is not better than that of the first generation. We also regret the lack of an equalizer with manual adjustment, even if the HeyMelody app makes up for this with the function golden sound and the practical insulation test.
The high-definition codec is not essential and unfortunately does not affect smartphones from major manufacturers such as Samsung or Apple. If you’re already happy Enco X owners, there’s no need to immediately replace them with the X2 model.
