Anker Soundcore vs EarFun Free 2S at a Glance
• Anker Soundcore Q20i — biggest strength: hybrid ANC built on four microphones, with 40 hours of playback with ANC on and 60 hours in normal mode. A five-minute top-up buys you roughly four more hours.
• Anker Soundcore Q20i — biggest trade-off: it's a 9.12-ounce over-ear with memory foam protein-leather cushions, which lands right where the arms of your glasses sit. ANC also works over Bluetooth only and pauses in wired mode.
• EarFun Free 2S — biggest strength: an in-ear bud at 3.99 g per side, IPX7 waterproof, 30 hours of total playtime with the charging case, and zero pressure on your frames.
• EarFun Free 2S — biggest trade-off: no active noise cancellation. You get passive sound isolation from the ear tip and nothing more.
• Buy the Anker Soundcore if you want real silence on a commute, long desk sessions, and automatic switching between a laptop and a phone.
• Buy the EarFun Free 2S if you wear glasses all day, work out, take calls on the move, or simply can't tolerate a headband.
The Q20i is Anker's take on the do-everything commuter headphone, and the design brief is unusually clear. Internal and external mics work together to knock down ambient noise — offices, trains, busy streets. Anker's own materials describe up to 90% ambient noise reduction, and the four-mic hybrid setup is the mechanism behind that claim. You toggle between ANC, Normal and Transparency either with a button or inside the soundcore app, which also gives you EQ presets, a custom EQ curve and built-in white noise.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The hardware is genuinely substantial. 40 mm dynamic drivers, a 20 Hz–40,000 Hz frequency range, 16-ohm impedance, Bluetooth 5 with a 10-meter range. BassUp pushes low end in wireless mode, and there's a real bonus for travelers: plug in the included 3.5 mm AUX cable and you unlock Hi-Res certified audio — though ANC switches off the moment you go wired. Dual-device pairing is the quiet hero here. Laptop and phone stay connected at once, and audio hops to whichever one needs you, so an incoming call doesn't wreck your flow. Charging takes about two hours, the warranty runs 18 months, and the finish is a blue faux-leather over-ear shell.
Who should buy it? Remote workers, commuters, students in loud libraries, and anyone who wants one pair of headphones to cover work and home listening. Who should skip it? Glasses wearers who get sore behind the ears after an hour, gym-goers — no water-resistance rating is listed — and anyone who wants earbuds that disappear into a pocket.
The Free 2S solves the problem the Q20i creates. Because it sits inside your ear canal with a rounded-tip in-ear fit, there is no headband, no clamping force, and nothing resting on the arms of your frames. If you've been hunting for earbuds with a microphone for glasses wearers, this is the design that removes the conflict entirely rather than trying to cushion around it.
The spec sheet is aimed squarely at everyday carry. A 7 mm composite dynamic driver tuned for deep bass with detailed mids and treble, 32-ohm impedance, a 20 Hz–20 kHz range, and Bluetooth 5.2 for stable pairing and auto-reconnect to the last device. The four built-in mics are explicitly pitched at hands-free calling: they isolate the frequencies of your voice and suppress surrounding noise, which matters when you take calls outdoors or in a car park. The EarFun app adds multi-EQ adjustment, custom touch controls, a battery readout and a game mode that lowers latency for video and mobile gaming.
Durability and charging are the practical wins. IPX7 waterproofing means rain and sweat aren't a concern, so these can live in a gym bag. You get USB-C and wireless charging — genuinely convenient if you already drop a phone on a pad every night. Battery figures are 7 hours per charge with 30 hours total from the case.
Who should buy it? Glasses wearers first and foremost, plus runners, cyclists, commuters who want a pocketable pair, and anyone who takes a lot of voice calls. Who should skip it? Frequent flyers who want engine drone cancelled rather than muffled, people who prefer the open feel of an over-ear cup, and anyone who wants a wired fallback — there's no headphone jack here at all.
Side-by-Side: Which Should You Choose?
• Best battery life → Anker Soundcore. 40 hours with ANC on, 60 hours in normal mode, plus a five-minute fast charge worth about four hours.
• Best for noisy commutes and shared offices → Anker Soundcore. Hybrid ANC plus a transparency mode when you need to hear the announcement.
• Best for workouts, sweat and rain → EarFun Free 2S. IPX7 waterproofing versus no listed water rating on the Anker.
• Best for calls on the move → EarFun Free 2S. Its four mics are specifically described around voice pickup; the Anker's four mics are described around noise cancellation.
• Best for switching between laptop and phone → Anker Soundcore. Simultaneous dual-device connection with automatic handoff.
• Best for extra bass → Anker Soundcore for sheer depth via BassUp; the EarFun's sealed in-ear fit gives more perceived punch at lower volume. If you're after the best extra-bass wireless earbuds for glasses wearers specifically, the in-ear seal does a lot of the work.
• Best for charging convenience and travel kit → a split decision: the EarFun wins on wireless charging, the Anker wins on in-flight use thanks to the 3.5 mm AUX cable.
For glasses wearers, I would buy the EarFun Free 2S. The reasoning is simple and it isn't about specs on paper — it's about the one thing you can't change: a headband and sealed ear cups sit directly on your glasses, while an in-ear bud doesn't. Add IPX7, wireless charging, four mics for calls and a 3.99 g per-side weight, and you have a pair you'll actually forget you're wearing. The Anker Soundcore Q20i is the better tool when silence and battery are the job — commute, office, long desk days — so if you only wear glasses occasionally and crave ANC, go that way instead. Everyone else: the EarFun is my pick.
FAQ
They work, but the seal is the issue. The memory-foam cushions need to fully cover your ears for ANC to perform, and glasses arms break that seal slightly. Loosening the headband helps; a perfect seal with glasses on is unlikely. That's the honest structural trade-off versus an in-ear design.
Anker, clearly. The Q20i lists 40 hours with ANC on and 60 hours in normal mode, with a five-minute fast charge giving about four extra hours. The EarFun Free 2S lists 7 hours per charge and 30 hours total with the case. If charging is your pet peeve, the Anker is the easier companion.
Not really — both list adult sizing, and the EarFun is listed for adults and teens. Neither is scaled for small heads or built with child-safe volume limits. If you're shopping the best kids headphones for glasses wearers, look at models explicitly designed for children rather than adapting an adult pair.
One last practical note: I deliberately haven't quoted any pricing here, because it moves and this is a spec-based comparison. Check the current price on Amazon for both before you commit — the value gap between an over-ear ANC headphone and a $—sorry, between these two categories is wider than the feature lists alone suggest.
