If you want an open-ear design that keeps you aware of traffic, your surroundings and your training partner while you listen, choose Monster Open Ear AC225; if you need maximum playtime, active noise cancelling and a charging case you can actually control without touching your phone, choose QJF Earbuds.
• Monster Open Ear AC225 — biggest strength: a true clip-on open-ear build with 13mm dual-composite drivers, directional audio that limits leakage, Bluetooth 6.0 and IPX6 water resistance.
• Monster Open Ear AC225 — biggest trade-off: open-ear means you get no active noise cancelling, and the promised 36 hours only arrive with the charging case (8 hours per charge).
• QJF Earbuds — biggest strength: a smart touch screen built into the charging case for volume, tracks, EQ and noise modes, plus ANC, 60 hours total playtime and Bluetooth 5.4.
• QJF Earbuds — biggest trade-off: the sealed in-ear fit blocks your surroundings, and each charge only lasts about 6 hours before the case is needed.
• Who each pick is for: Monster for runners, cyclists and commuters who want awareness and a secure clip-on fit; QJF for travellers, office workers and gym-goers who want quiet, long battery and full control on the case itself.
The Monster Open Ear AC225 is built around a specific idea: you should hear your music and your environment at the same time. Each earbud weighs just 5.1g, and the adaptive bridge is designed to self-conform to the shape of your ear, so the earbud clips on rather than plugs in. That's a meaningful difference if you've ever had in-ear tips loosen up mid-run or start to ache after an hour. The design also plays nicely with glasses and other accessories, which is a detail open-ear shoppers usually learn to care about the hard way.
On the audio side, Monster uses 13mm dynamic drivers with dual-composite diaphragms, tuned for punchy bass and clean highs. The directional audio technology is the interesting part — it channels sound toward your ear canal and limits how much leaks out, which is what lets you keep the volume up in a quiet office without broadcasting your playlist to the room. There's also ENC on the microphone, which reduces background noise on your end of the call. On paper that's a sensible match for windy streets, busy gyms and outdoor calls.
Who should buy it? Anyone who prioritises situational awareness, a pressure-free fit and a clip-on design that survives movement. Who should skip it? If you want to shut the world out on a plane or in a noisy open office, this isn't the tool — there's no active noise cancelling here, and open-ear designs let ambient sound in by nature. Note also that the 36-hour figure is a case-inclusive number, not per-charge.
QJF Earbuds: Who It's For
The QJF Earbuds go the opposite direction. These are in-ear headphones with active noise cancelling, and the headlining feature is a smart touch screen on the charging case. That screen lets you change volume, skip tracks, toggle noise cancellation, switch EQ modes and locate a misplaced earbud — all without pulling out your phone. If you've ever been on a packed train with your phone buried in a bag, you already understand why that's appealing.
Battery is the other headline. QJF quotes roughly 6 hours per charge and 60 hours total with the case, with a 1-hour charge time and Type-C fast charging. That's a big total figure for travel, long shifts or a week of short commutes between top-ups. The case itself is part of the product's identity here — it's a control surface, not just a battery box.
The fit is ergonomic and lightweight, and the enclosure uses thermoplastic elastomer, which is a soft, grippy material commonly chosen for earbuds that need to stay put. IPX5 water resistance covers sweat and splashes, so running, gym sessions and daily wear are all in scope. Bluetooth 5.4 handles pairing and connection stability, and touch controls on the buds cover calls, music and volume. The frequency response is listed up to 20,000 Hz with 16-ohm impedance, and the warranty runs to 2 years.
Who should buy it? Travellers, commuters, office workers and gym-goers who want noise cancelling, long total playtime and case-level control. Who should skip it? If you need to stay aware of traffic or your surroundings, the sealed in-ear fit and ANC work against you — that's the exact opposite of what an open-ear design is for.
• Best for situational awareness and outdoor safety → Monster Open Ear AC225. The clip-on open-ear design leaves your ear canal open, so traffic, cyclists and announcements still reach you.
• Best for noise cancelling and quiet focus → QJF Earbuds. ANC plus a sealed in-ear fit is the combination for flights, trains and open-plan offices.
• Best for total battery life → QJF Earbuds. 60 hours with the case beats the Monster's 36 hours, though the Monster lasts longer per single charge at 8 hours versus about 6.
• Best for a secure, pressure-free fit over long sessions → Monster Open Ear AC225. At 5.1g per bud with an adaptive bridge, nothing is pushed into your ear canal, and the clip-on shape coexists with glasses.
• Best for control without your phone → QJF Earbuds. The touch screen on the case handles volume, tracks, EQ and noise modes directly.
• Best for the newest wireless standard and range → Monster Open Ear AC225. Bluetooth 6.0 with a listed 12-metre range is the more advanced spec on paper; QJF uses Bluetooth 5.4.
• Best for water resistance → Monster Open Ear AC225. IPX6 is rated higher than the QJF's IPX5, which matters for heavy sweat and rain.
• Best for buyers who want a longer warranty on paper → QJF Earbuds. The QJF carries a 2-year manufacturer warranty versus Monster's 1 year.
• On price: neither sheet lists pricing, and I won't guess. Both are mainstream-priced categories, so check the current price on Amazon before deciding — the button on this page takes you there.
In my opinion, the Monster Open Ear AC225 is the better buy for most people shopping this comparison, because the open-ear clip-on format solves a problem that in-ear buds can't: it lets you stay present in the world while you listen, and the 8-hour single-charge runtime plus IPX6 and Bluetooth 6.0 make it a genuinely practical everyday pair. I'd steer toward the QJF Earbuds instead if your priority is silence and stamina — ANC, a touch-screen case and 60 hours total is a compelling combination for travel and office work. Match the design to your day, not the spec sheet to your ego.
FAQ
Yes. QJF lists active noise cancellation along with a smart touch screen for switching noise modes. The Monster Open Ear AC225 does not offer ANC — it uses ENC on the mic for calls only, which is a different thing.
It depends how you measure. The Monster gives 8 hours per charge and 36 hours with the case; the QJF gives about 6 hours per charge and 60 hours total with the case. So QJF wins on total, Monster wins on a single uninterrupted session.
Both are, in different ways. Monster is IPX6 with a clip-on fit that keeps your ears open for traffic and gym surroundings. QJF is IPX5 with an ergonomic in-ear fit and ANC for treadmill focus. If you run outdoors near roads, I'd lean Monster.
