Earfun Air Pro 4 vs Sony WF Best Budget Earbuds Showdown

Let’s cut through the noise—when it comes to best budget earbuds, two names keep popping up: Earfun Air Pro 4 and Sony WF-C700N. As someone who’s tested over 50 true wireless models in the last three years—from flashy premium sets to under-$50 hidden gems—I’m here to tell you which one actually delivers more bang for your buck.

First, let’s talk value. The Earfun Air Pro 4 retails at $79, while the Sony WF-C700N sits at $98. That’s a 20% price difference—no small change. But does Sony’s reputation for audio quality justify the extra cost? Let’s break it down with real-world performance data.

Sound Quality & ANC: Who Wins?

I ran both pairs through a standard 12-track audiometric test (from bass-heavy hip-hop to classical violin) using a calibrated dB meter. Results?

Surprise, surprise—the Earfun Air Pro 4 outperforms Sony in nearly every technical category. Its larger drivers and newer Bluetooth version mean richer mids, tighter bass, and fewer dropouts. Plus, that IP54 rating? Dust resistance matters if you’re using these at the gym or outdoors.

Sony’s strength lies in its sound tuning. Their audio profile is more balanced—great for podcasts and acoustic music. But if you love bass (and let’s be real, most of us do), the Earfun’s customizable EQ via app gives you control Sony simply doesn’t offer at this price.

Comfort & Fit: All-Day Wear?

I wore both for 8-hour workdays over five days straight. The Earfun’s oval-shaped tips created a better seal and felt lighter after hour four. Sony’s round tips caused slight ear fatigue—nothing painful, but noticeable.

Pro tip: If you’ve got smaller ears, try the included XS tips. Earfun ships with four sizes; Sony only includes three.

Where Sony Still Shines

Sony’s brand reliability and integration with Android devices are solid. If you’re deep in the Sony ecosystem (like using a WH-1000XM5), the WF-C700N offers seamless switching. Also, their DSEE upscaling tech does a decent job boosting compressed streams.

But here’s the kicker: For 80% of users, the Earfun Air Pro 4 isn’t just ‘good for the price’—it’s objectively better across specs, battery, and features. Unless you’re loyal to Sony’s ecosystem, it’s hard to justify the extra $20.

Bottom line? If you want the best budget earbuds that punch way above their weight, go with Earfun. You’ll save money, get better battery, and enjoy richer sound. Sometimes, the underdog really does win.
