• Avantree HF027 — biggest strength: a 3.5m coiled cable plus a 2m extension cable, so you can sit across the room from a TV or move around an office without unplugging anything.
• Avantree HF027 — biggest trade-off: it only works with a 3.5mm audio output jack, has no inline volume control, and the microphone needs a splitter on PCs with separate mic and headphone jacks.
• Orancu Earbuds — biggest strength: up to 8 hours per charge and roughly 40 hours total with the charging case, plus wireless and USB-C charging and an LED case display.
• Orancu Earbuds — biggest trade-off: no jack at all — everything runs over Bluetooth, and the case needs a wireless charger you supply yourself if you go that route.
• Who each pick is for: Avantree HF027 for TV, PC and keyboard players who want zero pairing and zero charging; Orancu Earbuds for phone, tablet and gym users who want no cables.
The HF027 is a problem-solver, not a fashion statement. Its whole reason for existing is distance. The 3.5m coiled cable stretches when you need reach and retracts when you don't, and Avantree throws in a separate 2m extension cable so you can run the line from a TV across a room without sitting on the floor. If you've ever wished you could keep watching a show while you walk to the kitchen, this is the design answer.
Sound-wise, the specs are plain and honest: 32 ohm impedance, a dynamic driver, and a 20Hz–20kHz frequency range, with soft silicone tips that isolate outside noise and a collar clip to keep the cable from yanking the earbuds out. No batteries, no pairing, no latency. You plug in, you listen. That matters for anyone who has fought with a TV that won't hold a Bluetooth connection, or a video game where audio lag ruins the timing. The package includes the earbuds, the extension cable, a cable clip and spare ear tips, with a carrying case in the box.
Who should buy it: TV watchers who don't want to disturb anyone else, PC and laptop users, and musicians or hobbyists plugging into an electronic keyboard or drum set. Who should skip it: anyone whose TV only has optical or coaxial output, anyone with a phone that dropped its headphone jack without an adapter, and anyone who wants volume control on the cable — there isn't any. PCs with separate audio and mic jacks will need a splitter to use the mic. These are real limitations, and Avantree lists them openly, which I respect.
The Orancu A12 goes the opposite direction: nothing plugs in, everything pairs. Take the buds out of the case and they connect automatically; the first time you just pick "A12" on your device, and after that they reconnect on their own. Bluetooth 5.1 handles the link, and the compatibility list covers iOS, Android and most Bluetooth-enabled devices — which is the closest thing to "works with everything" you get without a cable.
The battery story is the headline. Eight hours on a single charge, and the case holds enough for roughly three to four more rounds, putting total playtime near 40 hours. The case itself has a digital LED screen showing the case's remaining percentage plus four separate indicators for each earbud's charging status, so you're never guessing. It charges over USB-C or wirelessly — though the wireless charger isn't included, so that's on you if you want it.
For movement, the ear hooks are the point. They loop over your ear to hold the buds in place during workouts, and the IPX5 rating means sweat and splashes aren't a problem. Three sizes of ear tips are included so you can match your ear canal. Physical push buttons mean you won't accidentally skip a track by brushing your ear. There's a built-in mic for calls, and a low-latency mode aimed at gaming and video. Who should buy it: runners, gym-goers, commuters, and anyone who wants one pair for phone, tablet and laptop without thinking about wires. Who should skip it: people who need zero-latency wired audio, anyone who dislikes charging routines, and anyone who wants active noise cancellation — the sheet lists noise control as none.
• Best for reaching across a room → Avantree HF027. The coiled 3.5m cable plus 2m extension is unmatched for TV distance listening.
• Best for total freedom of movement → Orancu Earbuds. No cable at all, with ear hooks that keep them planted.
• Best for battery life → Orancu Earbuds. Up to 8 hours per charge and about 40 hours with the case; the HF027 needs no power whatsoever.
• Best for zero setup → Avantree HF027. Plug into a 3.5mm audio output and you're done — no pairing, no charging, no reconnection quirks.
• Best for workouts and sweat → Orancu Earbuds. IPX5 water resistance and a sport-focused hook design; the HF027 is a sit-down listening tool.
• Best for gaming and video timing → Avantree HF027. Wired audio means no wireless latency to worry about.
• Best for using one pair on phone, tablet and laptop → Orancu Earbuds. Bluetooth handles the switching; the HF027 needs a compatible 3.5mm jack or an adapter on every device.
• Best for TV without disturbing others → Avantree HF027. Sound-isolating tips plus long reach make it the natural late-night pick.
In my opinion, most people shopping this comparison should buy the Orancu Earbuds. The reason is simple: "all devices" in 2026 usually means a phone, a tablet and a laptop, and Bluetooth covers all three with nothing to plug in — plus you get the battery display, the ear hooks and roughly 40 hours of total playtime. I'd pick the Avantree HF027 instead if your priority is a television or a desktop setup where a wire is genuinely better, or if you're tired of charging and pairing altogether. For a TV across the room, the long coiled cable is the feature that actually solves your problem, and no wireless bud can match that simplicity.
how to disconnect headphones from all devices
Turn the headphones off or place them back in the charging case, then open your device's Bluetooth settings and remove or "forget" the pairing entry. On the Orancu A12, keeping the earbuds in the case and away from the device stops them reconnecting. The Avantree HF027 has no pairing at all — unplug the 3.5mm jack and it's disconnected.
how to make headphones forget all devices
The reliable method is to clear the pairing list on the device side: go to Bluetooth settings and delete or forget the headphone entry. Doing this on every device that has ever paired with the Orancu A12 prevents automatic reconnection. Because the HF027 is wired, there is nothing to forget — it has no stored connections.
how to unpair headphones from all devices
Unpairing is per-device, so repeat the "forget this device" step on each phone, tablet or computer. If old devices keep grabbing the connection, turn their Bluetooth off temporarily. The Orancu A12 reconnects automatically after the first pairing, so removing the entry on each device is what stops that behavior.
how to listen to two devices at once with headphones
Listening to two sources simultaneously isn't something either model advertises. The Orancu A12 pairs to one Bluetooth device at a time and reconnects automatically to the last one used, so you'd switch rather than listen to both. The Avantree HF027 takes a single 3.5mm input, so it plays one source at a time as well.
