How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single-ear, voice-controlled headset for calls, driving and work, choose Heayzoki Earpiece; if you need an open-ear, clip-on pair for running and outdoor training with a touch screen and a charging case, choose TANFESO Open Ear Clip.
• Heayzoki Earpiece — biggest strength: a single in-ear headset with an ergonomic tilt, soft ear hooks, voice control and an LED digital power display, built around talking and wearing it for hours. Biggest trade-off: it is one ear only, in-ear, with no water-resistance rating and no charging case in the box.
• TANFESO Open Ear Clip — biggest strength: a featherweight 0.18 oz clip-on pair with an intelligent touch screen, Bluetooth 5.4, IPX7 waterproofing, a charging case and bone conduction drivers. Biggest trade-off: open-ear sound leaks in ambient noise by design, it is touch-controlled rather than voice-controlled, and the warranty is short at two months.
• LED digital display: both products put a digital readout on the power source — Heayzoki on the earpiece itself, TANFESO on the charging case.
• Choose Heayzoki Earpiece if you take a lot of calls, drive for a living, or want one ear free and hands-free voice commands.
• Choose TANFESO Open Ear Clip if you run, cycle, lift, sweat heavily, or want to keep both ears open to traffic and surroundings.
• One line each: Heayzoki is the talk-first headset; TANFESO is the move-first training pair.
The Heayzoki Earpiece is a mono Bluetooth headset — one earpiece, in-ear, held in place with soft ear hooks that adjust to your ear. The housing sits at an ergonomic tilt angle, which is the detail that matters most here: a tilted single-ear headset tends to sit stably without pressing on one spot, and the spec sheet calls it painless to wear. For anyone who keeps a headset on through a long shift, that comfort angle is the whole point.
On the audio side, Heayzoki describes a three-frequency balance with stereo surround processing, treble, steady bass and sub-bass. That is marketing language, so treat it as a design intent rather than a promise — a single 13 mm dynamic driver in one ear cannot produce true stereo separation, because stereo needs two channels. What it can do is deliver full-range sound into one ear, which is exactly what you want for spoken word: calls, navigation prompts, voice notes. Bluetooth 5.2 with a stated 10 m range (the description mentions up to 15 m in open space) covers phone-in-pocket and phone-on-desk distances comfortably.
The features that actually sell this one: voice control for hands-free operation, and an LED intelligent digital display that shows remaining power instead of making you guess from a blinking light or a beep. Charging is about 1.5 hours per the specs, roughly 2 hours per the description, off a built-in lithium-ion battery the sheet calls large-capacity. In the box: the earpiece, a charging cable, an ear cover and a manual.
TANFESO Open Ear Clip: Who It's For
The TANFESO Open Ear Clip is the opposite philosophy. It is a clip-on pair — the M100 — that hooks over your ear with soft silicone and never enters your ear canal. The spec sheet lists the driver type as bone conduction, and the weight as 0.18 oz, which is genuinely light for something that stays on through running, dancing or wearing glasses. The streamlined sinking design is there specifically to keep the clips planted when you move.
Two features separate it from a generic open-ear set. First, the intelligent touch screen — you tap the display to control music and calls instead of hunting for buttons, and that same screen handles the LED digital display for power. Second, Bluetooth 5.4 with a stated 33 ft range and an auto on-and-connect behaviour when you lift the buds out of the case, which is the newest Bluetooth version in this comparison and the one most likely to hold a stable, low-latency link.
Then there is the case. The TANFESO ships with a portable charging box plus a USB-C cable, so recharging happens in your bag rather than at a wall. It carries an IPX7 waterproof rating, meaning it is built to survive sweat and rain in a way the Heayzoki sheet makes no claim about. There is a built-in mic with noise reduction for calls, and the colour on the sheet is purple.
The trade-off is inherent to the design: open-ear means you hear the world. TANFESO frames that as the safety benefit — approaching cars on a run or ride — and it is, but it also means wind, traffic and gym noise compete with your audio. If you want isolation, this is the wrong category. Also note the warranty is listed at two months.
Buy it if you train outdoors, sweat hard, want both ears free of canal pressure, or want a case and waterproofing. Skip it if you mostly take calls in an office, want voice control, or need maximum isolation.
Side-by-Side: Which Should You Choose?
• Best for calls and voice control → Heayzoki Earpiece. Voice control is its listed control method; TANFESO is touch-only.
• Best for battery convenience → TANFESO Open Ear Clip, because it includes a portable charging case; Heayzoki relies on a cable and its on-earpiece LED display.
• Best for newest Bluetooth → TANFESO Open Ear Clip with Bluetooth 5.4 and a stated 33 ft range versus Heayzoki's 5.2 and 10 m.
• Best for one-ear, wear-all-day use → Heayzoki Earpiece. A single tilted in-ear unit with adjustable hooks is simpler to live with at a desk or in a car.
• Best for situational awareness → TANFESO Open Ear Clip. It does not plug the canal, so you keep hearing your surroundings.
• Best for durability against sweat and rain → TANFESO Open Ear Clip, on the strength of the IPX7 rating alone.
• Best for a mono music listener who wants full-range sound in one ear → Heayzoki Earpiece, with its 13 mm dynamic driver.
• Warranty consideration → TANFESO lists two months; Heayzoki's sheet lists no warranty term at all, so neither is a long-term coverage story.
If I had to pick one, I would buy the TANFESO Open Ear Clip (B0H18CVJH3) — for most people shopping this category, the combination of IPX7 waterproofing, Bluetooth 5.4, a 0.18 oz clip-on fit, a charging case and a touch-screen display covers more real situations than a single-ear headset does. The one case where I would go the other way is if your day is built around phone calls, driving and hands-free voice commands: there, the Heayzoki Earpiece's voice control and single-ear design fit the job better. In my opinion, the TANFESO is the broader buy and the Heayzoki is the specialist buy. Check the current price on Amazon before deciding, since neither sheet gives a figure here.
Yes. Both products here are consumer electronics — wireless audio devices with built-in rechargeable batteries, Bluetooth radios and control electronics. The Heayzoki Earpiece runs Bluetooth 5.2; the TANFESO Open Ear Clip runs Bluetooth 5.4 with a touch screen and charging case. Both are battery-powered and need charging, which is what puts them firmly in the electronics category.
Can you connect earbuds to a TV?
That is a personal call, and the sheets only give you one option each. The Heayzoki Earpiece is listed in black; the TANFESO Open Ear Clip is listed in purple. If you specifically want black or white, Heayzoki is the black option here, and neither sheet offers a white variant.
The TANFESO sheet says yes by design — 0.18 oz, soft silicone ear hooks, an ergonomic surround and streamlined sinking shape meant to hold on through running, dancing or wearing glasses. It is also IPX7 waterproof, so sweat and rain are covered. Heayzoki lists no water-resistance rating and no sport fit claims beyond its adjustable ear hooks.
