What it is & who it's for
The Soundpeats Air4 Pro are the latest attempt by the budget audio brand to prove you don't need to spend $200 to get a genuinely good pair of true wireless earbuds. With a list price of around $60, they promise hybrid active noise cancellation, wireless charging, and a sound profile tuned by the folks at Knowles. For anyone who's tired of earbuds that sound like tin cans or fall out of your ears during a jog, these are squarely aimed at you.
I've been using them for two weeks as my daily drivers—commuting on the subway, working in a noisy coffee shop, and taking calls on the go. They're not perfect, but they've made me question why I ever spent more than $100 on earbuds. Here's the honest breakdown.
Specs at a glance (manufacturer-claimed)
| Metric | Soundpeats Air4 Pro |
|---|---|
| Bluetooth | 5.3 |
| Microphones | 6 |
| Drivers | 12mm dynamic + Knowles balanced armature |
| Water resistance | IPX5 |
| Codecs | LDAC (Android), AAC (iOS) |
| Earbud battery (ANC on) | ~5.5 hr |
| Total battery with case | ~20 hr |
| Case recharges | ~2.5× |
| EQ | 5-band custom |
Sound Quality: The Star of the Show
The Air4 Pro sound impressive for the price. The dual-driver setup—a 12mm dynamic driver for bass and a Knowles balanced armature for treble—delivers detailed, energetic sound that rivals earbuds twice the price. Bass is punchy but not overwhelming, mids are clear, and highs sparkle without turning harsh.
LDAC support lets you stream hi-res audio on Android, and the difference is noticeable on tracks with complex instrumentation. On iPhone you're limited to AAC, which still sounds good. The default tuning is a slight V-shape, but the companion app's EQ lets you dial it in.
ANC and Transparency: Surprisingly Effective
The hybrid ANC is effective. It won't silence a jet engine, but it tames the low-frequency rumble of a subway car or office HVAC well enough that you can focus without cranking the volume to dangerous levels.
Transparency mode is above average, letting in enough ambient sound to catch an announcement or hold a quick conversation without removing the earbuds. There's a slight hiss in quiet environments, but it's not a dealbreaker at this price.
Comfort and Controls: Almost There
The Air4 Pro are lightweight and comfortable for extended wear. Angled nozzles and soft silicone tips create a secure seal—I ran 5K without a single adjustment—and the IPX5 rating handles sweat and light rain.
Touch controls are responsive and customizable via the app, but the touch surface is too sensitive; I accidentally paused music while adjusting the fit. The app is basic but functional: EQ presets, ANC modes, and firmware updates.
Key limitations (the parts the marketing doesn't cover)
- Call Quality Is Subpar The microphones pick up your voice clearly in quiet rooms, but in any wind or background noise, callers complained of muffled audio and echo. If you take calls on busy streets or in open offices, these will frustrate you.
- Build Quality Feels Cheap The glossy plastic case and earbuds are fingerprint magnets and feel less premium than the price suggests. The case hinge has a bit of wobble, and I worry about long-term durability.
- No Multipoint Connection You can only connect to one device at a time. Switching between your phone and laptop requires manual disconnection and re-pairing, which is annoying if you work across devices.
How it compares
Compared to the Anker Soundcore Liberty 4 NC (around $80), the Air4 Pro offer better sound detail and LDAC support, but the Liberty 4 NC have superior ANC and call quality. The EarFun Air Pro 3 (around $50) are a closer competitor—they lack the dual-driver clarity but have a more robust app and better battery life. If you're an iPhone user, the Air4 Pro's LDAC advantage is moot, and the AirPods Pro 2 (at triple the price) still win on seamless integration and transparency.
Who should buy / skip
Worth considering if:
- You're an Android user who wants hi-res audio on a budget
- You prioritize sound quality and ANC over call clarity
- You need a comfortable, secure fit for workouts and commutes
Look elsewhere if:
- You make a lot of phone calls in noisy places
- You need seamless multi-device switching
- You want a premium-feeling, durable case
The Isaac Standard verdict
3.5 / 5. The Soundpeats Air4 Pro are a rare case where a budget brand delivers on its headline promises. Sound quality and ANC are genuinely impressive for $60, and comfort is top-notch. The poor call quality and flimsy build are real compromises. If you can live with those, these are a steal. If not, spend a bit more on the Liberty 4 NC or save up for the AirPods Pro 2.
Frequently asked
Do the Soundpeats Air4 Pro work with iPhones?
Yes—they connect via Bluetooth and sound good, but LDAC is Android-only. On iPhone you get AAC, which is fine, but you miss the hi-res advantage.
How is the battery life in real-world use?
About 5.5 hours with ANC on, close to the 6.5-hour claim. The case adds roughly 2.5 charges, putting total battery at around 20 hours. Wireless charging works, but it's slow.
Are these good for running?
Yes—the fit is secure and the IPX5 rating handles sweat. Just watch the touch controls; you may accidentally pause your music while adjusting them.
Can I use the companion app to adjust the EQ?
Yes. The Soundpeats app offers EQ presets and a 5-band custom EQ. It's basic but functional, with touch-control customization and ANC mode selection as well.
