If you want an open-ear pair with a real bass engine, a huge 42-hour total runtime and the convenience of wireless charging, choose Anker Soundcore AeroFit 2; if you need a featherweight clip-on design that never touches your ear canal, physical buttons you can't mis-press, and the newest Bluetooth standard, choose EarFun Clip 2.
• Anker Soundcore AeroFit 2 — biggest strength: a 20mm × 11.5mm racetrack driver with BassTurbo and LDAC Hi-Res audio, backed by 42 hours of total playtime and a wireless-charging case.
• Anker Soundcore AeroFit 2 — biggest trade-off: it's an ear-hook design with touch controls and no physical buttons, and the ear hooks plus case bring the set to 85 g — noticeably more to carry than a clip-on.
• EarFun Clip 2 — biggest strength: a 5.5 g-per-bud C-shaped clip with a nickel-titanium memory wire, Bluetooth 6.0, and 4-mic AI call clarity — it disappears on your ear and never enters the canal.
• EarFun Clip 2 — biggest trade-off: battery is shorter (11 hours per charge, 40 total, and only about 6 hours with LDAC on), and the charging case isn't covered by the IP55 rating.
• Who each pick is for: AeroFit 2 for listeners who prioritise sound depth, marathon battery and cable-free charging; Clip 2 for runners, commuters and glasses-wearers who want the lightest possible fit and tactile controls.
The AeroFit 2 is Anker's take on open-ear audio done big. The headline spec is the driver: a 20mm × 11.5mm racetrack-shaped dynamic unit paired with soundcore's BassTurbo tuning. Open-ear designs usually struggle to move air, so a driver this size is the whole point — it's how the AeroFit 2 chases "rich bass, clear mids, vivid treble" instead of the thin, tinny sound that gives open-ear a bad name. LDAC support pushes it into Hi-Res wireless territory, which matters if you stream from a service that actually serves high-bitrate files.
Comfort here comes from a double-curved surface and soft, adjustable ear hooks, with four adjustable positions so you can angle the sound toward your canal without plugging it. The 10-hour single-charge figure is genuinely strong for open-ear, and the case stretches that to 42 hours — enough that charging becomes a weekly chore rather than a nightly one. The case also supports wireless charging, which sounds minor until you've lived with a tangle of cables on a bedside table. Four beam-forming mics plus an AI algorithm handle calls, and IP55 covers sweat and rain.
Buy it if you want the most sound-focused open-ear experience of the two, you hate plugging in cables, or you take long calls and want the extra microphone array. Skip it if you want the absolute lightest thing on your ear, you prefer real buttons over touch, or you specifically want the latest Bluetooth generation. The 85 g total (buds plus case) and the ear-hook shape also make it the bulkier of the two to pocket.
The Clip 2 takes the opposite philosophy: get out of the way. Each bud weighs 5.5 g, and instead of hooking over your ear it clips on with a C-shaped bridge — 40° of ultra-soft silicone wrapped around a 0.5 mm nickel-titanium memory wire you can stretch and rotate to match your ear. Nothing enters the ear canal at all. EarFun says the bridge was tested through 20,000+ flexes, which speaks to the durability question anyone asks about a wire that gets bent daily.
Sound comes from a 12mm titanium-composite dynamic driver with a dual-magnetic circuit, plus LDAC and Hi-Res certification and EarFun's Spatial Stage processing for a wider stage. Here's the trade-off you need to know: with LDAC enabled, single-charge battery drops to about 6 hours, versus 11 hours on standard codecs. That's the cost of high-bitrate streaming on a small bud. Fast charging helps — 10 minutes gets you roughly 2.5 hours.
The feature list is unusually current: Bluetooth 6.0 with multipoint so you can hop from a tablet video to a phone call without re-pairing, Google Fast Pair for setup, IP55 on the buds (case excluded), and real-time AI translation across 100+ languages through the EarFun Audio App. Controls are physical push buttons, not touch — a deliberate choice that eliminates accidental taps mid-run. The 18-month warranty is also longer than the 90-day limited warranty on the AeroFit 2.
Buy it if you run, cycle or commute, wear glasses, hate things inside your ears, or want buttons you can find by feel in the dark. Skip it if you're a high-bitrate streamer who needs long single-charge endurance, or you want wireless charging.
• Best for bass depth and Hi-Res listening → Anker Soundcore AeroFit 2. A 20mm × 11.5mm racetrack driver with BassTurbo is simply more driver area than a 12mm unit.
• Best for all-day, all-week battery → Anker Soundcore AeroFit 2. 10 hours per charge, 42 total, versus 11/40 — and the Clip 2 falls to roughly 6 hours once LDAC is on.
• Best for the lightest fit → EarFun Clip 2. 5.5 g per bud and a memory-wire clip beat ear hooks for most people who find hooks fiddly.
• Best for running and workouts → EarFun Clip 2. The secure C-bridge, physical buttons and IP55 buds suit sweaty, jostling use better than touch controls.
• Best for calls in noisy places → EarFun Clip 2 on paper, with 4 mics and AI noise cancellation; the AeroFit 2 counters with 4 beam-forming mics and its own AI algorithm, so both are well equipped.
• Best for charging convenience → Anker Soundcore AeroFit 2. Wireless charging plus USB-style flexibility beats a cable-only case.
• Best connectivity and device switching → EarFun Clip 2. Bluetooth 6.0, multipoint and Google Fast Pair edge out Bluetooth 5.4.
• Best for travel and translation → EarFun Clip 2, if the 100+ language real-time translation via the app is something you'd actually use.
My Verdict
The AeroFit 2 lasts longer: 10 hours per charge and 42 hours with the case, versus 11 hours and 40 hours for the Clip 2. Note that the Clip 2 drops to about 6 hours per charge when LDAC is enabled.
For running, I'd lean Clip 2. Its 5.5 g clip-on design with a memory-wire bridge, IP55 buds and physical buttons are better suited to movement than ear hooks with touch controls.
Yes — both list LDAC and Hi-Res audio. The AeroFit 2 uses a 20mm × 11.5mm racetrack driver, while the Clip 2 uses a 12mm titanium-composite driver with a dual-magnetic circuit.
I don't quote prices here since they change often — check the current price on Amazon. On features alone, the AeroFit 2 gives you more battery and wireless charging, while the Clip 2 offers Bluetooth 6.0, an 18-month warranty and a lighter clip-on fit.
