EarFun Free 2S Review: The Best Value Earbuds?

---

The original EarFun Free 2 was already one of the safest budget recommendations around, so when the Free 2S landed, I was curious—but also a little skeptical.

Usually, “S” upgrades come with a higher price tag or a list of changes you barely notice in daily use.

After spending time with the EarFun Free 2S, I can confidently say this is one of those rare updates that actually matters.

EarFun fixed some of the biggest limitations of the original model, refined the sound, and somehow kept the price firmly in budget territory.

At around $60 retail—and often closer to $30 with discounts—these earbuds are aiming straight at the “best value” crown.

So, are they really that good? Let’s get into it.

Design & Build

At first glance, the Free 2S doesn’t look dramatically different from the Free 2. The charging case is almost identical in size and shape, which is no bad thing—it’s compact, pocket-friendly, and feels solid enough for daily use.

Around the back, you still get USB-C charging and a pairing button, while a single LED on the front gives you a quick idea of the battery status.

The earbuds themselves, though, tell a slightly different story. EarFun has cleaned up the design by moving away from the teardrop-style touch surface of the original.

The Free 2S now uses a fully circular touch area, which looks simpler and, more importantly, feels more consistent when you’re tapping controls.

One subtle but important change is underneath. The charging pins have been redesigned with a deeper contact area and stronger magnetic connection.

In real-world use, this means the earbuds snap into place more reliably and are less likely to suffer from charging issues over time. It’s not flashy, but it’s exactly the kind of upgrade that improves long-term reliability.

Fit-wise, these are small, lightweight earbuds that sit comfortably in the ear. Even during longer listening sessions, I never felt the need to take them out for a break, which is more than I can say for some bulkier budget options.

App Support

This is, without question, the most important improvement over the original Free 2.

The Free 2S finally works with the EarFun app, and that changes the entire experience. With the original model, what you heard out of the box was what you were stuck with. Now, you can actually tailor the earbuds to your taste.

Inside the app, you’ll find preset EQ modes along with custom equalizer options, firmware updates, and control over features like low-latency gaming mode. That alone makes the Free 2S feel far more modern and flexible than its predecessor.

What I like most is that you’re not forced to use the app all the time. Once you’ve set things up the way you like, the earbuds remember your settings, so you can just enjoy your music without constantly tweaking anything.

Controls

Touch controls on budget earbuds can be hit or miss, but EarFun has done a solid job here. Right out of the box, the Free 2S gives you access to all the essentials: play and pause, track skipping, volume control, and even toggling gaming mode.

The touch surface is responsive without being overly sensitive, which means fewer accidental taps when adjusting your earbuds. If the default layout doesn’t suit you, the app lets you customize controls, which is still surprisingly rare at this price point.

Connectivity and Durability

The Free 2S uses Bluetooth 5.2, and connection stability has been rock-solid in my testing. Pairing is quick, and once connected, I didn’t experience random dropouts or sync issues.

Support for aptX is another welcome bonus. While it won’t magically turn these into audiophile earbuds, it does help with cleaner sound and reduced compression, especially if you’re using a compatible Android device.

For outdoor use, the IPX7 rating is a standout feature. These earbuds are fully waterproof, not just splash-resistant. Rain, sweat, or even an accidental drop into water won’t phase them. That kind of durability is still uncommon in this price range and makes the Free 2S an easy recommendation for workouts or daily commuting.

Call Quality

For phone calls and video chats, the Free 2S does a respectable job. The microphones pick up your voice clearly in quiet environments, and noise reduction helps keep background sounds under control when you’re out in public.

This isn’t broadcast-quality audio, but that’s not the expectation here. What matters is that people on the other end can hear you clearly, and in my experience, the Free 2S delivers on that front.

---

Sound Quality

This is where the Free 2S really separates itself from the original Free 2.

The older model leaned heavily into bass, sometimes to the point where it overshadowed the mids and treble. With the Free 2S, EarFun has clearly reworked the tuning. The bass is still powerful and satisfying, but it no longer dominates the entire sound signature.

Vocals come through cleaner and more detailed, whether you’re listening to male or female singers. Treble has been lifted just enough to bring out subtle details without sounding harsh or fatiguing. The result is a brighter, more balanced sound that works across a wider range of genres.

Soundstage and imaging have also improved. Instruments feel more spread out, and it’s easier to pick out where different elements are coming from. For a pair of budget earbuds, the overall presentation is impressively spacious.

With the app’s EQ options, you can push the sound in different directions if you want more bass or extra clarity, but even straight out of the box, the tuning feels well-judged.

Battery Life and Charging

Battery performance is exactly where it needs to be. You’ll get around seven hours of playback from the earbuds themselves, with the charging case pushing total listening time to roughly 30 hours.

Wireless charging is supported, which still feels like a luxury feature at this price. Being able to drop the case onto a Qi charger and walk away is genuinely convenient.

Fast charging is another feature I’ve come to appreciate more than I expected. A quick 10-minute top-up gives you about two hours of playback. If you’re rushing out the door and realize your earbuds are dead, this can be a real lifesaver.

Final Thoughts

The EarFun Free 2S is proof that you don’t need to spend a fortune to get excellent wireless earbuds. It nails the essentials—clear, balanced sound, long battery life, full waterproofing, and handy app customization—while staying incredibly affordable.

It may skip features like ANC or multipoint, but for most users, it delivers everything that really matters.

If you want reliable, versatile earbuds that punch well above their price, the Free 2S is hard to beat.
