• amzluv Replacement Ear Hooks — biggest strength: a soft silicone clamp-style loop that lets you re-seat a single-ear headset on either ear instead of replacing the whole thing.
• amzluv Replacement Ear Hooks — biggest trade-off: it is a spare part, not a headset. Buy it expecting sound and you will be disappointed.
• Sunffice Open Ear Headphone — biggest strength: an all-in-one open-ear earpiece with an ENC mic, IPX5 waterproofing and long battery figures.
• Sunffice Open Ear Headphone — biggest trade-off: it is strictly single-ear, so anyone wanting stereo music gets one channel only.
• Who each pick is for: amzluv for the tinkerer keeping an old headset alive; Sunffice for the driver, courier or caller who wants one ready-to-go earpiece out of the box.
Think of this as a repair kit, not a gadget. The amzluv ear hook is a small silicone loop in black, sized around 2.3 x 1.1 x 0.15 inches, and it comes as a set of three. Its entire job is to replace the worn, snapped or lost over-ear hook on a single-ear Bluetooth headset. You push the neck of your headset into the neck of the hook, rotate it to the angle that suits your ear, and wear it on the left or the right. That is the whole product.
The material choice matters here. Silicone is soft and flexible, which is exactly what you want pressing against the back of your ear for an hour-long call. The brand describes it as environmentally friendly and non-toxic, and notes that it may not look identical to your original manufacturer hook — but it still does the job. That honesty is worth something, because replacement hooks rarely match an OEM part cosmetically.
Compatibility is broad but specific. amzluv lists Plantronics models plus brands like Newbee, Link Dream, Glazata, Kendir, TOORUN, Hawksbill and YW YUWISS. The one hard limit: this fits single-ear headsets only. It will not work with wireless earbuds or over-ear headphones. If that is what you own, skip it. If you have a trusty single-ear headset whose hook has given up, this is the sensible fix — and with three in the pack, you have spares for the next time one goes. A one-year manufacturer warranty backs it up.
The Sunffice Open Ear Headphone is the opposite kind of purchase: a complete, self-contained earpiece. It uses a bone conduction driver in an open-ear shape, so nothing sits inside your ear canal. That non-in-ear design is the headline feature, and it is genuinely useful — you keep ambient sound around you while you talk, which matters on a bike, on a job site or walking through traffic. The rotatable earhook lets you flip it between left and right, and at just 9 grams you are meant to forget you are wearing it.
For calls, there is an ENC microphone that filters background noise, and the spec sheet promises clear conversation in loud places. Controls are physical buttons on the earpiece: play/pause, answer/reject, and a summon for Siri or another voice assistant. There is a nice practical touch — you can switch the voice prompt language between Chinese and English by pressing the function button once while the earpiece is unpaired.
Battery is where this thing stands out on paper. Sunffice quotes up to 720 hours of standby, up to 48 hours of talk time and 26 hours of listening, with a 1.5-hour charge via the included Type-C cable. Bluetooth 5.2 gives a stated 15-metre range, and iOS shows the battery level on screen. IPX5 means sweat and rain are not a problem. It works with Android, iOS and Windows, and the colour here is pink with a plastic enclosure. One warning the brand repeats: this is a single-ear headphone, and only one is in the box.
Who should skip it? Anyone expecting a pair. This is one earpiece for calls, driving, workouts and work — not a stereo listening setup.
Side-by-Side: Which Should You Choose?
• Best for a complete, ready-to-use earpiece → Sunffice Open Ear Headphone. No old hardware required.
• Best for long call sessions → Sunffice Open Ear Headphone. The quoted talk-time figure is measured in days of standby and dozens of hours of calls.
• Best for sweat and rain → Sunffice Open Ear Headphone. IPX5 waterproofing versus a part with no water rating at all.
• Best for keeping your ear canal open → Sunffice Open Ear Headphone. The open-ear, bone conduction design is built around awareness.
• Best for low-commitment spending → amzluv Replacement Ear Hooks. It is a small accessory with three pieces in the pack, so check the current price on Amazon before deciding.
• Best for left/right flexibility → both. Each one rotates to fit either ear.
• Best for people who own wireless earbuds or over-ear headphones → neither. amzluv explicitly excludes those, and Sunffice is a single-ear earpiece.
If I had to pick one, I would buy the Sunffice Open Ear Headphone. In my opinion it is the more complete product: it solves the whole problem in one box, with an ENC mic, IPX5 protection, Bluetooth 5.2 and battery figures that comfortably cover a working day of calls. The amzluv ear hooks are a smart, cheap fix — but only if you already own a single-ear headset worth saving. If you do, buy the hooks. If you do not, buy the Sunffice.
A single earpiece. The brand states clearly that only one headphone is in the package, along with a Type-C charging cable and a manual.
Only if it is a single-ear Bluetooth headset. amzluv lists Plantronics plus brands like Newbee, Glazata, Kendir, TOORUN, Hawksbill and YW YUWISS, and explicitly rules out wireless earbuds and over-ear headphones.
The Sunffice, based on its specs — it has an integrated ENC microphone designed to filter background noise. The amzluv hooks have no electronics at all.
The Sunffice is designed for exactly that: an open-ear fit that keeps you aware of your surroundings, IPX5 for sweat and rain, and button controls for hands-free calls. The amzluv hooks just hold a headset on your ear.
