The wait is almost over. OPPO is ready to unveil the Enco X4 on September 22, and the earbuds have already revealed more than just their new look.
The design, three colour options, and key audio features are now being promoted, while several important hardware details remain behind the curtain.
OPPO Enco X4 Launch Date and Design Are No Longer a Mystery
The OPPO Enco X4 will make its global debut in China on September 22, alongside the company’s upcoming Find X10 series and Watch S2. The launch places OPPO’s new premium TWS earbuds at the centre of its broader ecosystem push.
The company has also begun revealing the Enco X4’s design ahead of the event, giving us a clear look at its compact in-ear form and charging case. Importantly, the China debut should not be confused with confirmed international retail availability. OPPO has yet to announce India or wider global sales details.
Three Enco X4 Colours Have Been Listed
The current China listings reveal three finishes:
| OPPO Enco X4 colour | Status |
| Soft White | Confirmed |
| Pink Gold | Confirmed |
| Titanium Grey | Confirmed |
These colours should be treated as the currently revealed China lineup rather than proof of global availability. OPPO has not yet detailed international retail plans for the Enco X4.
Dynaudio, Smarter ANC and Premium Audio Take Centre Stage
Dig a little deeper, and there’s more going on under the hood. OPPO is officially promoting the Enco X4 around Dynaudio audio technology, lossless sound and intelligent noise cancellation.
The earbuds are being positioned as a premium audio product rather than a routine successor. Dynaudio branding also continues the collaboration associated with OPPO’s higher-end Enco X family.
The other major focus is intelligent, scenario-based ANC, suggesting that the noise-cancellation system is designed to adapt to different listening environments rather than relying on a single fixed cancellation profile. However, OPPO has not yet disclosed the performance figures needed to quantify the upgrade.
What Is Confirmed?
| Feature | Current Status |
| Dynaudio audio | Officially promoted |
| Lossless audio | Officially promoted |
| Intelligent/scenario-based ANC | Officially promoted |
| Exact ANC reduction | Unknown |
| Driver specifications | Unknown |
| Codec support | Unknown |
That distinction keeps the marketing claims separate from specifications that can only be verified after OPPO publishes the complete sheet. AI Real-Time Translation Is Now Officially Promoted
AI Real-Time Translation Is Now Officially Promoted
This is where the Enco X4 gets more interesting. Unlike earlier reports that treated AI real-time translation as a leak, OPPO is now officially promoting the translation capability as part of the Enco X4’s feature set.
What remains unclear is the technical and regional fine print. OPPO has not yet provided complete details on the number of supported languages, supported language combinations, processing method, or whether every translation feature will be available in every market.
Earlier reports had specifically pointed towards English and Simplified Chinese translation, but those details should not automatically be expanded into a complete language list without official confirmation.
| AI translation detail | Status |
| AI real-time translation | Officially promoted |
| Specific supported languages | Not fully detailed |
| English/Simplified Chinese support | Previously reported |
| Full language list | Unknown |
| Exact implementation | Unknown |
| Regional availability | Unknown |
This makes the Enco X4’s AI pitch more substantial than the earlier leak cycle suggested, but there are still enough unanswered questions to wait for OPPO’s September 22 presentation.
TDRA Certification Adds Another Piece
The Enco X4 has also appeared in the TDRA certification database under model number ETEM2, providing another indication that the product has moved through regulatory channels ahead of its debut.
The certification itself does not reveal the complete hardware specification. It is therefore useful context, but not a substitute for OPPO’s official specification sheet.
What We Still Don’t Know?
This is where the Enco X4 story remains incomplete. Despite the growing list of confirmed features, OPPO has yet to reveal several specifications that will matter to buyers.
| Specification | Status |
| Price | Not announced |
| Battery Capacity | Unknown |
| Earbud battery life | Unknown |
| Driver configuration | Unknown |
| Audio codecs | Unknown |
| Maximum ANC performance | Unknown |
| IP rating | Unknown |
| India availability | Unconfirmed |
| Global availability | Unconfirmed |
These details will ultimately determine how the Enco X4 stacks up against other premium TWS options. For now, the strongest confirmed story is its combination of Dynaudio audio, lossless sound, intelligent ANC, and officially promoted AI translation.

The Enco X4 Completes OPPO’s September 22 Ecosystem Push
The Enco X4 isn’t arriving alone. OPPO’s September 22 event is shaping up as a wider ecosystem launch, with the Find X10 series, Watch S2 and new premium earbuds sharing the spotlight.
That gives the Enco X4 a clear role: it becomes OPPO’s flagship audio companion for the new hardware generation, rather than simply another standalone TWS refresh.
With the design and colours already out in the open, the September 22 event now has one major job left: to fill in the technical gaps.
Final Thoughts
OPPO has officially put Dynaudio audio, lossless sound, intelligent ANC and AI real-time translation on the Enco X4’s feature map, while price, battery, drivers, codecs and international availability remain unanswered. September 22 fills the remaining gaps.
