Design & Case
EarFun isn’t trying to reinvent anything here—and honestly, that’s fine.
The case is made of lightweight matte plastic, pocket-friendly, and clean. The lid has a satisfying lock when opened fully (a tiny detail I always appreciate), and the single LED on the front keeps battery info simple.
On the back sits the USB-C port, and yes—the case supports Qi wireless charging, a feature many $200 earbuds still skip.
Pop the lid and you’ll see a small pairing button in the middle. The earbuds themselves stick to the familiar stem design, with a slightly larger stem than the AirPods Pro but still far from anything bulky or awkward. They’re light, well-balanced, and stay put without constant readjustments.
Fit & Comfort
The Air S fits like a textbook stem-style earbud. They disappear into your ears after a few minutes, and EarFun includes four sizes of eartips, which help nail the seal.
For gym workouts, I usually prefer something with an ear hook, but for everyday walking, commuting, and desk use, the Air S works perfectly fine.
Touch controls are responsive and customizable through the EarFun app. Out of the box, I found the layout a little limiting—no way to go back to the previous track—but a quick trip to the app fixed that.
Once remapped, I could control volume, tracks, ANC modes, and playback without ever touching my phone.
App & Features
The EarFun Air S pairs with the EarFun Audio App, giving you far more control than what you get straight out of the box. The app is clean, lightweight, and easy to navigate, making it simple even for first-time users.
Inside the app, you can customize the sound with a full EQ, choose from preset sound profiles, and fine-tune the audio to match your listening style. The app also lets you toggle Noise Cancellation, Ambient Mode, and Normal Mode with a single tap.
Gamers will appreciate the dedicated Low-Latency Gaming Mode, which reduces audio delay for smoother gameplay. You can also remap touch controls, update the firmware, and check battery levels for each earbud individually.
Overall, the EarFun Audio App adds meaningful features that enhance usability and give you deeper control over your earbuds without feeling complicated.
ANC & Transparency Mode
This was the part that surprised me the most. Most sub-$100 ANC earbuds barely knock out low-frequency hum—air conditioners, bus engines, the usual.
The Air S takes it a step further.
It handles low-end noise well and manages to dampen human voices more than expected. No, it doesn’t reach Sony or Bose levels, but it gets you shockingly close considering the price bracket.
The transparency mode is impressive too—clear, usable, and without the static or hiss that budget models often suffer from. It leans slightly digital, but perfectly fine for talking without removing the earbuds.
Call Quality
Four microphones help keep calls clean and understandable. Voices stay crisp, and background noise is reduced enough to remain functional in busy environments.
You’re not getting AirPods Pro call clarity, but it’s absolutely more than serviceable for daily calls or meetings.
Sound Quality
This is where the EarFun Air S really flexes.
Right out of the box, the sound signature is bold:
- Heavy, punchy bass
- Bright, lively treble
- Forward mids that put vocals right in front of you
It’s the kind of sound that makes everything—pop, EDM, rock, metal—feel energetic. The bass has real depth, even dropping into sub-bass territory with a gentle rumble. Guitars have weight, drums hit with authority, and vocals sit confidently on top of the mix.
If you prefer a flatter, reference-style sound, you’ll need to adjust the EQ. But if you enjoy a dynamic, room-filling profile, these hit the sweet spot without any tweaking.
And yes—they get loud. Much louder than the AirPods Pro. I rarely pushed them past 70–80% volume.
Battery Life
On a full charge, you’re looking at around six hours of playback with ANC off. Total listening time with the case jumps to about 30 hours. That’s perfectly in line with other ANC earbuds at this price, and better than some premium brands.
The only drawback?
There’s no fast charging. You’ll need roughly an hour to top up the earbuds.
Still, wireless charging softens the blow, and in daily use, it never felt like a real inconvenience.
Final Thoughts
After spending real time with the EarFun Air S, it’s hard to point to any other earbuds in this price range that deliver this combination of features, sound, and everyday usability.
You’re getting strong ANC, wireless charging, multi-point pairing, aptX support, a customizable app, lively audio, a comfortable fit, and battery life that holds up well.
Yes, you miss out on fast charging and the transparency mode isn’t quite premium-tier, but those feel like small trade-offs considering what you’re paying.
If someone asked me today for the best earbuds under $70, I’d honestly say the EarFun Air S without hesitation. They’re not just good for the price—they’re simply good.
