SoundPEATS Engine 4 Review 2026: Planar Magnetic TWS at Just ¥299

The SoundPEATS Engine 4 delivers a genuine planar magnetic driver in a true wireless form factor for just ¥299 ($41) — a price that would typically only get you entry-level dynamic driver earbuds. With LDAC support, 8-hour battery life, and a 97% positive rating across 20,000+ JD.com reviews, these earbuds are redefining what “budget audiophile” means in the Chinese TWS market. The catch? No ANC and only passive isolation.

Design & Build Quality

The SoundPEATS Engine 4 follows the brand’s recognizable angular design language. Each earbud weighs just 4.5g — impressively light for a planar magnetic TWS, given that planar drivers typically require more mass than dynamic drivers. The fit is secure and comfortable for extended listening sessions, though the stem-based design may protrude slightly more than compact rivals.

The charging case is where the budget price shows. While functional and compact enough to slip into a pocket, the plastic construction lacks the premium feel of competitors at similar price points. The hinge has a slight wobble, and the lid doesn’t snap shut with the satisfying thud of more expensive cases. That said, it gets the job done — USB-C charging is present, and the 32-hour total battery means you won’t be reaching for a charger often.

IPX4 water resistance covers sweat and light rain, making them suitable for gym sessions, but we wouldn’t recommend wearing them in a downpour.

Sound Quality: The Planar Magnetic Difference

This is the Engine 4’s killer feature. Let’s talk about what planar magnetic drivers actually do.

Most TWS earbuds use dynamic drivers — essentially tiny speakers with a cone attached to a voice coil inside a magnetic field. Planar magnetic drivers work differently: a thin, flat diaphragm with embedded conductive traces sits between two arrays of magnets. When current passes through those traces, the entire diaphragm moves uniformly, driven across its whole surface rather than being pushed from the center.

The practical result? Faster transient response, lower distortion, and much better detail retrieval. Where dynamic drivers can sound congested in complex passages, planar magnetics maintain separation between instruments. The bass hits with speed and precision rather than boom and bloom. The midrange is open and natural. High frequencies extend cleanly without the piercing quality some affordable dynamic drivers produce.

On the Engine 4 specifically, the 14.2mm planar driver delivers sound that genuinely rivals wired IEMs in the ¥200–500 range. Vocal clarity is outstanding — breath details and subtle reverb tails that get lost on most TWS earbuds are clearly audible. Instrument separation in busy rock tracks and orchestral pieces is a genuine step above anything with a conventional dynamic driver at this price.

The catch is isolation. Without ANC, you’re relying entirely on the passive seal of the silicone tips. In a quiet room or home office, that’s fine — the sound quality shines. On a noisy Beijing subway or a busy Shanghai street, external noise bleeds through significantly. At moderate volume, much of that micro-detail gets masked by ambient noise. These are best enjoyed in controlled environments.

Battery & Connectivity

Battery life is a strong point: 8 hours per charge puts the Engine 4 ahead of most ANC-equipped TWS earbuds, which typically manage 5–6 hours with ANC on. The charging case adds three additional full charges for a total of 32 hours.

Bluetooth 5.3 provides reliable connectivity with low latency. The real highlight is LDAC support — Sony’s high-resolution audio codec that transmits up to 990 kbps, nearly three times the bandwidth of standard AAC or SBC. On the Engine 4, LDAC connection stability is excellent. Users report consistent connectivity even with the phone in a pocket or bag, with dropouts being rare.

For LDAC to work, you’ll need a source device that supports it (most modern Android phones do; iPhones do not). If you’re on iOS, the earbuds fall back to AAC, which is still good but doesn’t leverage the planar driver’s full resolving ability.

“It sounds like wired IEMs but without the cable. The clarity is addictive.” — Xiaohongshu audiophile

Value

“¥299 for planar magnetic TWS is insane value. Normally you’d pay ¥500+ just for wired planar IEMs.” — Xiaohongshu

“Build quality is solid but the charging case feels slightly cheap. For the sound quality though, I’ll take it.” — Xiaohongshu

ANC Compromise

“No ANC is a shame, but the sound quality makes up for it.” — JD verified

“Good for home or office use. Not enough isolation for commuting.” — JD verified

“Passive isolation works okay in quiet environments. If you need noise cancellation, look elsewhere.” — Xiaohongshu

Xiaohongshu Community Feedback

The Xiaohongshu audiophile community has embraced the Engine 4 as a gateway product — a way to experience planar magnetic sound without the investment typically required. Threads comparing the Engine 4 to wired IEMs under ¥500 are common, with most commenters agreeing the Engine 4 holds its own or beats similarly priced wired options for sheer detail retrieval.

A common recommendation on the platform: pair the Engine 4 with foam ear tips for improved passive isolation. Users report that Comply-style foam tips reduce ambient noise noticeably, making the earbuds more usable in noisier environments without sacrificing comfort.

vs Engine 3: The Engine 4’s planar driver is a clear step up in sound quality, justifying the ¥70 premium. If sound quality is your priority, the Engine 4 is worth the upgrade.

vs QCY Melobuds ANC: The Melobuds offer ANC and solid LDAC support for ¥50 less. You’re trading ANC for the planar driver’s superior detail. Choose based on your listening environment.

vs Edifier TWS1 Pro 2: A more balanced all-rounder with ANC at a lower price, but the dynamic driver cannot match the Engine 4’s resolving ability. The Edifier is the safer pick for commuters; the Engine 4 is for audio enthusiasts.

Who Should Buy

• Budget audiophiles wanting to experience planar magnetic sound without spending ¥500+
• Home and office listeners who prioritize sound quality over noise isolation
• LDAC-capable Android users who want high-resolution wireless audio on a budget
• Wired IEM converts looking for a wireless upgrade without sacrificing detail

Who Should Skip

• Daily commuters who need ANC to block subway/bus noise
• iOS users (no LDAC support limits the sound quality advantage)
• Users who prioritize ANC — look at QCY Melobuds ANC or Edifier TWS1 Pro 2 instead
• Those who want a premium-feeling case — the plastic charging case may disappoint

FAQ

Is the SoundPEATS Engine 4 worth ¥299?

Absolutely. The planar magnetic driver alone makes this exceptional value. Comparable wired planar IEMs cost ¥400–800. Getting that driver technology in a TWS form factor with LDAC for ¥299 is a genuine bargain.

Does the Engine 4 have active noise cancellation?

No. The Engine 4 relies entirely on passive isolation from the ear tips. It works well in quiet environments but struggles in noisy public spaces. Consider foam tips to improve isolation.

Can I use LDAC on iPhone?

No. iOS does not support LDAC. The Engine 4 will use AAC on iPhones. The sound quality is still good, but you miss the high-resolution advantage.

Gold Verdict

The SoundPEATS Engine 4 is a specialized product that excels brilliantly in its lane. For ¥299, you get planar magnetic TWS that sound better than most earbuds at twice the price — provided you can live without ANC. The charging case is the weakest link, but when you’re listening to music, the case sits in your pocket, and the planar drivers in your ears deliver a listening experience that rivals wired audiophile gear.

This isn’t the best all-rounder TWS at ¥299. But if pure sound quality is your north star, nothing in this price bracket touches the Engine 4. It’s a statement product from SoundPEATS: planar magnetic audio is no longer a luxury reserved for the deep-pocketed. It’s ¥299, and it’s wireless.

The Engine 4 earns a Gold rating for delivering genuinely enthusiast-grade sound at a mass-market price, even with its ANC omission.
