OPPO Enco X4 reach Italy at €219.99. The phone decides which features you get
Lossless audio, translation and battery claims need their conditions attached. Bluetooth pairing alone does not unlock the full feature list.
OPPO's Enco X4 earbuds have an Italian price and a long feature list, but the phone in your pocket decides how much of that list you can actually use. The Italian store lists them at €219.99. Their most eye-catching audio claim, lossless transmission up to 2.3Mbps, has a narrower compatibility condition than ordinary Bluetooth pairing.
On its Italian product page, OPPO specifies a Find X10-series phone with a MediaTek processor for that maximum lossless connection. That detail matters more than a broad statement that the earbuds work with Android and iOS. Connecting, configuring and accessing every advertised function are different levels of compatibility.
Follow the audio all the way to the ear
Lossless describes whether the audio data survives a particular part of the journey without lossy compression. It does not, by itself, establish that an earbud sounds better. The original recording, the source supplied by the music service, the wireless connection and the acoustic fit each belong to the listening experience. A better transport cannot restore detail that the source never supplied.
Nor does a transmission rate measure noise cancellation or comfort. Someone buying for a train commute may value a reliable seal and useful cancellation more than a codec mode their current handset cannot enable. Someone already using the specified Find X10 hardware has a different calculation. That is why this is an ecosystem decision as well as an audio purchase.
OPPO describes a dual-driver, dual-DAC design tuned with Dynaudio. Those are construction and tuning details, not independent listening results. They give the product a clear acoustic proposition without proving how it compares with similarly priced alternatives in a particular listener's ears.
Read battery life with the listening mode attached
The product page's detailed battery table is more useful than its largest number. OPPO lists these laboratory figures for the earbuds alone:
| Listening mode | Claimed playback |
|---|---|
| AAC, noise cancellation off | 13 hours |
| AAC, noise cancellation on | 6 hours |
| LHDC, noise cancellation on | 5.5 hours |
These are manufacturer figures, not our measurements. The same page lists up to 53 hours with the charging case in AAC with cancellation off. That total combines listening and subsequent recharges; it does not describe one uninterrupted session with the buds in your ears. OPPO's introductory battery prose is inconsistent about cancellation, so the mode-labelled table is the useful reference here.
The distinction is practical. A long journey with cancellation enabled should be planned around the relevant single-charge figure, with allowance for real use, rather than the case total. Turning a headline feature on may change another headline specification. That is a tradeoff worth seeing before purchase, not discovering at the departure gate.
Buy the features your phone can deliver
The Italian listing removes uncertainty about whether this is merely an overseas product announcement. It does not make the same price or configuration universal outside Italy. Buyers elsewhere should use their local listing, and Italian buyers should still check the precise phone and software requirements for the functions they want.
For wireless audio, the most revealing specification is sometimes a footnote. Enco X4's value depends on the intersection between what the earbuds offer and what the connected phone supports. The right comparison starts with that intersection, not with the longest feature list.
