Spending $80 on earbuds feels risky when a $15 pair sits on the next shelf over. That tension between the Earfun Free Pro 3 and the MINISO M66 OWS is exactly where budget buyers get stuck.
The Earfun Free Pro 3 vs MINISO M66 OWS comparison looks straightforward on paper. One costs more, has more features, and wins on specs. Done, right?
Not quite. These two earbuds belong to completely different design categories, and that changes everything about which one suits your life.
The Earfun Free Pro 3 is a traditional in-ear earbud with ANC. The MINISO M66 OWS sits outside your ear canal entirely. Comparing them without addressing that difference is like reviewing a sedan against a motorcycle using the same checklist.
The Form Factor Problem No Comparison Covers
Almost every comparison between the Earfun Free Pro 3 and the MINISO M66 OWS lines up specs in a table and declares a winner. That approach misses the single largest difference between these products: they don’t even go in the same part of your ear.
In-Ear vs Open-Ear: Two Different Listening Philosophies
The Earfun Free Pro 3 uses silicone ear tips that create a seal inside your ear canal. That seal is what makes ANC possible. It also traps heat, creates pressure, and can cause fatigue after a couple of hours.
The MINISO M66 OWS (Open Wearable Stereo) hooks around the ear and directs sound toward the canal without entering it. There is zero seal. Sound leaks out. Ambient noise gets in. And your ears breathe.
These are opposite approaches to the same problem. Picking one based on a spec sheet alone ignores the physical reality of wearing them.
Why This Matters for Daily Comfort
A sealed in-ear bud like the Earfun Free Pro 3 works great for commutes, flights, and noisy environments. But if your day involves sitting at a desk for six hours with earbuds in, that constant seal creates a stuffy, pressurized feeling. The MINISO M66’s open design eliminates that entirely.
I think the Earfun Free Pro 3’s ANC is overrated for desk workers, since SoundGuys measured only 10 to 30dB of noise reduction depending on the frequency range. That means high-pitched sounds like keyboard clatter and voices still cut through. At a desk, the MINISO’s open-ear awareness gives you a similar functional experience for a fraction of the price.
Earfun Free Pro 3 vs MINISO M66 OWS Sound Quality
Sound is where the price gap becomes audible. The Earfun Free Pro 3 runs on a Qualcomm QCC3072 chip with Bluetooth 5.3 and support for aptX Adaptive codec. That codec allows high-resolution audio transfer at up to 24bit/96kHz on compatible Android devices. iOS users miss out on aptX entirely.
The MINISO M66 OWS supports standard Bluetooth with SBC and AAC codecs. No high-res audio. No advanced codec handshake. The audio is clean enough for podcasts, calls, and casual playlists, but it lacks the detail separation you get on the Earfun.
Bass and Detail Separation
The Earfun Free Pro 3 packs 7mm wool composite drivers inside a sealed shell. That sealed environment lets bass frequencies build up properly. CNN Underscored’s review noted that tracks like Jon Batiste’s “Freedom” produced deep, punchy bass without distorting the overall mix.
The MINISO M66 OWS can’t match that. Open-ear designs lose bass by nature because there’s no seal to contain low-frequency vibrations. Expecting thumping bass from OWS earbuds is like expecting a convertible to keep rain out.
Call Clarity in Noisy Spots
The Earfun Free Pro 3 uses a 6-microphone array for call noise reduction. Multiple reviews note that while it handles light background noise reasonably well, louder environments cause muffling and bleed-through.
The MINISO M66 handles calls at a basic level. One or two microphones do the work, and noisy surroundings affect voice clarity faster. For quick calls in a quiet room, it works fine. For a 30-minute meeting while walking through a city, the Earfun is a better bet.

Battery, Charging, and Daily Convenience
Battery life matters differently depending on how long your listening sessions run. These two earbuds split nicely along that line.
| Feature | Earfun Free Pro 3 | MINISO M66 OWS |
|---|---|---|
| Per-charge playtime (ANC off) | Up to 7.5 hours | 4 to 6 hours |
| Total with case | Up to 33 hours | Around 20 to 24 hours |
| Charging method | USB-C + wireless charging | USB-C only |
| Low-latency mode | 55ms game mode via app | Standard latency |
The Earfun Free Pro 3 wins the battery race, especially with wireless charging as a bonus. If you drop it on a Qi pad at night, it’s always ready. The MINISO M66 relies on USB-C only, which is fine for most people but less convenient if you already have a wireless charging station on your desk.
Build Quality and Durability Over Time
The Earfun Free Pro 3 has an IPX5 water resistance rating, meaning sweat and light rain won’t damage it. The case is compact but slightly thick. Multiple long-term reviews mention the earbuds holding up well after months of daily use, with the ear hooks keeping them seated during movement.
The MINISO M66 OWS has a lighter build aimed at casual daily use. The materials feel more budget-conscious, and the open-ear hooks, while comfortable, may show wear sooner with rough handling.
One thing that matters more than people realize: ear tip replacement. The Earfun Free Pro 3 ships with multiple ear tip sizes, and replacements are easy to find.
The MINISO M66 doesn’t use ear tips at all (since it sits outside the ear canal), which means there are no parts to replace. That’s one less maintenance step to think about. Check the Earfun Free Pro 3 specs on the official site.
The Earfun Audio App vs No App at All
The Earfun Audio app gives you a 10-band EQ, touch control customization, ANC mode switching, firmware updates, and a game mode toggle. That’s a lot of control for a sub-$80 earbud.
The MINISO M66 OWS doesn’t have a companion app. The sound profile is fixed. Touch controls handle play, pause, and call functions. No EQ tweaking, no firmware updates.
This is where buyer personality splits hard. Some people love opening an app, adjusting five sliders, and testing different ANC modes. Others pop earbuds in, hit play, and forget about it. The MINISO caters to the second group.
When the App Makes a Real Difference
Here is where I’d push back on the common advice to “always pick the one with more features.” The Earfun Free Pro 3’s EQ matters because, according to multiple audio reviewers, the default tuning is bloated in the bass and messy in the treble out of the box.
The earbuds start sounding significantly better after EQ adjustments. That means the app isn’t a bonus feature. It’s a near-requirement to get the sound right.
If an earbud needs an app to sound good, that’s a design limitation dressed up as a feature.
Who Should Buy the Earfun Free Pro 3
The Earfun Free Pro 3 fits a specific buyer profile. The earbud suits people who need the following:
- Daily commuters dealing with bus, train, or city noise who want ANC to cut through ambient sound
- Android users who can take advantage of aptX Adaptive for better audio resolution
- Podcast and audiobook listeners who wear earbuds for long stretches and want extended battery life past 6 hours
- Gym-goers who need sweat resistance and a secure in-ear fit during movement
The $79 price tag is reasonable for all of that. Sales frequently drop it to $50 to $60 on Amazon, which makes it a strong mid-range pick. MINISO’s open-ear OWS models sit at the opposite end of the price range for a reason.
Who Should Buy the MINISO M66 OWS
The MINISO M66 OWS fits a different buyer:
- Desk workers and students who listen to music or podcasts for hours and want zero ear fatigue
- People who dislike in-ear pressure or get ear infections from sealed earbuds
- Casual listeners who don’t care about high-res audio codecs or EQ customization
- Budget-first buyers who would rather spend $15 to $25 and replace earbuds annually than invest $80 in a single pair
The open-ear design is the feature here, not a limitation. If staying aware of your surroundings while listening matters to you, the MINISO M66 does that by default without needing a transparency mode toggle.
Questions People Ask About Earfun Free Pro 3 vs MINISO M66 OWS
Q: Can the MINISO M66 OWS block out noise like the Earfun Free Pro 3? No. The MINISO M66 is an open-ear design, so it lets ambient sound in on purpose. There is no ANC and no passive isolation. If noise blocking is a priority, the Earfun Free Pro 3 is the only option between these two.
Q: Does the Earfun Free Pro 3 work well with iPhones? It works, but iOS devices can’t use aptX Adaptive. That means iPhone users lose the high-res audio codec advantage. The Earfun still sounds good over AAC, but the biggest audio upgrade is limited to Android.
Q: Are MINISO earbuds worth buying for daily use? For casual listening and calls, absolutely. MINISO OWS earbuds are lightweight, comfortable for long sessions, and cheap enough to replace without stress. The trade-off is weaker bass and no advanced sound tuning.
Q: How long do the Earfun Free Pro 3 last before needing replacement? Multiple long-term reviews report solid durability over 12 or more months of daily use. The IPX5 rating and build quality hold up well. Battery degradation over time is normal for any lithium-ion cell, so expect some capacity loss after 18 to 24 months.
Q: Is it worth paying more for ANC earbuds under $100? That depends entirely on where you listen. ANC on budget earbuds typically handles low-frequency humming well but struggles with voices and sharp sounds. Paying extra for ANC makes sense on buses and planes, but less so at a quiet desk.
Conclusion
The Earfun Free Pro 3 and MINISO M66 OWS solve different problems at different price points. Picking a winner between them without knowing your daily listening habits is a coin flip. The Earfun delivers better audio fidelity, longer battery, and noise control for $79.
The MINISO gives comfort-first, zero-fatigue listening for a fraction of that price. The smartest move is matching the form factor to your actual routine, not buying based on which spec sheet looks longer.
