Oppo Enco X4 Launch: Dynaudio Sound, AI Translation, Specs

Oppo launched the Enco X4 earbuds in China today, September 22, 2026, alongside the Find X10 phones and the Watch S2, built around a Dynaudio-tuned sound system and a new AI real-time translation feature (design and colors first confirmed via Gizmochina’s pre-launch report). This is the fourth generation of Oppo’s collaboration with the Danish loudspeaker maker, and the metallic-trim redesign plus the translation feature are the two things actually worth paying attention to here, rather than treating this as a routine annual refresh.

What’s actually new

Oppo is calling out “lossless Dynaudio sound quality” as the headline audio claim, continuing the co-engineering partnership it’s used on the Enco X series for several generations now — Dynaudio’s involvement has consistently been Oppo’s way of differentiating its earbuds from the sea of similarly-specced true wireless buds on the market, rather than competing purely on noise-cancellation numbers. Alongside the sound tuning, Oppo added scenario-based intelligent noise cancellation, meaning the earbuds are meant to adjust their cancellation profile based on what you’re actually doing — commuting, working in an office, or exercising — instead of applying one blanket ANC setting everywhere.

The bigger functional addition is AI real-time translation, a feature that’s been showing up across more premium earbuds this year as on-device AI processing gets fast enough to handle it without a noticeable lag. Oppo hasn’t detailed exactly which languages are supported or whether the feature requires an internet connection, so treat the capability as confirmed in concept but not yet fully specified.

Design and colors

The Enco X4 gets a visual upgrade too — Oppo describes it as looking more high-end than the outgoing Enco X3s, with new metallic trim on the case and buds. It’ll launch in three colorways: Soft White, Natural Pure Pink Gold, and Romantic Elegant Titanium Gray, a lineup that leans toward a more premium, jewelry-adjacent aesthetic than the sportier color palettes a lot of competing earbuds use.

Why the Dynaudio partnership keeps being the story

It’s worth understanding why Oppo keeps leaning on the Dynaudio name generation after generation rather than developing an in-house sound identity the way some competitors do. Dynaudio has decades of reputation in home and studio audio, and partnering with an established acoustics brand gives Oppo instant credibility with audiophile-leaning buyers in a category where sound quality claims are notoriously hard to verify from a spec sheet alone. Whether that translates into a genuinely better listening experience than earbuds without a name-brand partnership is something that really only shows up in side-by-side listening tests, but it’s a smarter marketing angle than just quoting driver size and frequency response numbers that most buyers can’t meaningfully interpret anyway.

The AI translation feature is the more interesting long-term bet. Real-time translation has been a “coming soon” promise on earbuds for a few years now, with mixed real-world results — latency, accuracy across language pairs, and how naturally the translated audio actually sounds have all been sticking points on earlier attempts from other brands. If Oppo’s implementation genuinely works well in daily use rather than just demo conditions, it could become a meaningful differentiator; if it’s laggy or limited to a handful of major languages, it’ll end up as a check-box feature most buyers never actually use.

It’s also a reminder that the earbuds category has gotten a lot more competitive on features beyond raw sound quality this year — vivo’s Buds Clip, which launched just a day earlier, took a completely different approach by leaning into fashion-accessory styling over spec-sheet bragging rights. Between translation features, scenario-aware ANC, and open-ear fashion designs, “just play music well” has clearly stopped being enough to stand out in this segment.

What Oppo hasn’t confirmed yet

A few specifics that matter for a buying decision are still missing from today’s launch details: driver size, battery life and case charging figures, codec support (whether it includes something like LDAC or Oppo’s own high-res codec for the “lossless” claim to actually mean something technical rather than just marketing language), and pricing. “Lossless” is a word that gets used loosely in earbuds marketing — it can mean anything from genuine hi-res codec support down to simply “we didn’t compress the audio further than the source file,” so I’d wait for Oppo’s full spec sheet or an independent teardown before taking that claim at face value.

Pricing will also matter a lot here. The Enco X series has historically sat in the upper-mid-tier of Oppo’s earbuds lineup, priced above its standard Enco Air and Enco Buds lines but below dedicated audiophile-focused earbuds from companies like Sony or Bose. Where the X4 lands within that band, and whether the new translation feature pushes the price up meaningfully from the X3s, isn’t public yet.

Frequently asked questions

What is Dynaudio’s role in the Oppo Enco X4?

Dynaudio, a Danish loudspeaker and audio engineering company, co-tunes the sound profile of the Enco X series, a partnership Oppo has continued across multiple generations to differentiate its earbuds on audio quality rather than spec-sheet numbers alone.

Does the Enco X4 support real-time translation?

Yes, Oppo confirmed an AI real-time translation feature at launch, though it hasn’t detailed which languages are supported or whether the feature requires an active internet connection.

How is the Enco X4 different from the Enco X3s?

Oppo says the Enco X4 has a more premium look with new metallic trim, plus scenario-based intelligent noise cancellation and the new AI translation feature, none of which were part of the X3s generation.

Is the Oppo Enco X4 available outside China?

Not as of today’s launch. Oppo confirmed the China release date but hasn’t announced international availability, similar to the Watch S2 that launched alongside it.

How much do the Oppo Enco X4 cost?

Oppo hasn’t published pricing as of today’s launch. Based on where the Enco X series has historically sat in Oppo’s lineup — above its budget Enco Air and Enco Buds models — expect a mid-to-premium price once official numbers are confirmed.
