About two years after the debut of the Enco X, flagship true wireless headphones (TWS) considered among the best on the market for the category (which we reviewed at the time), Oppo relaunches with the second generation: the Enco X2. In a thriving sector such as that of in-ear earpieces, where the outputs follow one another at a fast pace and manufacturers do not skimp on improvements and refinements, to make their choice fall on one or the other model is today very difficult. Price or design, functionality or audio quality, all the factors are now weighed indiscriminately: much depends on taste, personal needs and the functions available.
We had quickly put our hands on it at the Mobile World Congress 2022 and the curiosity was so great, given the wait. After a few weeks of use, I will tell you about my experience in this review.
The appearance of the Enco X2 is a great déjà-vu: not only for the similarity with the previous model, from which it differs for some additional details, but also for the obvious reference to the style of the Apple, a trend that today also unites other TWS manufacturers and therefore not surprising (I, personally, like it a lot). The oval case, which guards and recharges the earphones at the same time, has a glossy white finish that does not retain fingerprints but that gets dirty rather easily, a problem also shared by other models with similar materials and coloring. Despite the absence of quality materials – it is still polycarbonate – the build quality is good and the case appears robust, with an impeccable magnetic closure, thanks to a well-firm hinge that avoids the risk of accidental openings and falls of the earphones.
The Enco X2 are easily carried and placed in your pocket without excessive bulk; as on the previous model, the case is in fact flat (only 22.7 mm thick), an aspect that many will like. The weight of the case is quite low, with its approximately 47g.
Even the earphones are reminiscent of the old Enco X, while maintaining their individuality: I appreciated the small silver details on the ends and the very short stems for the discretion (they are much less noticeable), the ergonomics and the right interlocking with my ears (a little less for the touch controls, but I will come back to this later), assisted by a really well built anatomical main body. Useful and elegant also the inserts that differentiate the cap for the right ear from that for the left, black in the version supplied by us.
The in-ear fit is excellent: the inevitable ear tips, hated by many but loved by as many (including myself), fit perfectly into the auricle and do not stress the ear even after prolonged listening sessions, as long as you choose the right size among the many in the package. The headphones also remain well embedded in the ear even in case of sustained movement of the head and body, a not negligible aspect if you usually use them during sports or in situations of particular dynamism. I found them generally comfortable, also because the weight of the individual earphones is only 4.7g and is well distributed, thanks to the presence of the stems.
Pairing the headphones with a device is very simple: if you use an Android smartphone, just open the case near the device to see the pairing pop-up appear on the display. For iOS, however, you will need to download the HeyMelody app, which includes additional information about the earphones and has a pleasant and intuitive interface. The Enco X2 can connect to two devices at a time, a typical high-end option that lately is starting to embrace even the lower ranges.
The touch controls placed on the stems produce good haptic feedback and are based on the gestures of the “Squeeze”, the so-called “pizzicata”, unlike other TWS models that work by tap (which I, personally, prefer). It will take a single press to play or pause a song or reattach the call, double to move to the next track (or reject a call), triple to return to the previous track, extended to activate, deactivate or adjust noise cancellation, and so on. To adjust the volume directly from the earbuds, a possibility difficult to find on most of the competition, you have to slide your finger up and down instead.
The earphones are receptive and the controls intuitive, however the reduced length of the stems, although commendable from an aesthetic and ergonomic point of view, limits the field of action, making input a little more difficult.
I’ll get straight to the point: the Enco X2 sounds really good. The yield is remarkable with any musical genre: crystal clear high frequencies, balanced but not exaggeratedly deep bass and soft mids that make listening well detailed.
The credit goes to an acoustic system that boasts the collaboration, now multi-year, of the Danish speaker manufacturer Dynaudio, the optimization of the noise cancellation system, the presence of the Hi-Res mode and the Improvements on the SoC side, which include a refinement of the internal structure of the DAC chip and the introduction of a higher quality audio inductor.
To go even further into technical detail, the internal architecture of the Enco X2 is composed of a coaxial system with dual SuperDBEE (Dynamic Bass Enhace Engine) drivers, 11 mm dynamic drivers and 6mm balanced membrane drivers, combined with integrated ultra-light diaphragms and a quadruple magnet planar tweeter that guarantee even higher performance. In addition, the new LHDC 4.0 protocol has increased the wireless audio transmission rate to 900 kbps/24 bit/96 kHz, about three times higher than traditional technologies. Bluetooth is in version 5.2.
The performance on the call is also excellent: the voice of the interlocutor resonates clear and clear, as well as ours, thanks to the dual noise-canceling microphone of each headset and the new bone conduction sensors that are able to capture the vibrations of the voice to return a clearer sound even in particularly noisy environments.
