How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of open-ear clip earbuds that double as a jewelry accessory you can restyle to match your mood, choose soinfo Open Earphones; if you need a workout-ready set with a purse-shaped charging case, a battery readout and splash resistance, choose Alfu Clip.
• soinfo Open Earphones — biggest strength: detachable accessory ear clips (diamond-studded earrings in the box) plus ENC noise cancellation on calls and Bluetooth 5.4.
• soinfo Open Earphones — biggest trade-off: no water-resistance rating is listed, so heavy sweat or rain is a question mark.
• Alfu Clip — biggest strength: IP5 splash resistance and up to 16 hours of total battery life, with a digital display on the case so you can see the charge level.
• Alfu Clip — biggest trade-off: no noise cancellation is listed, and the charging case is bulkier by design because it's styled like a small purse.
• Pick soinfo Open Earphones if you want jewelry that happens to play music and clear phone calls matter to you.
• Pick Alfu Clip if you want one set for gym sessions, runs and long days, and you'd rather glance at a battery number than guess.
The soinfo Open Earphones are built around a simple idea: the earbud is also the accessory. Each earbud weighs just 4.5g, and the "clip on" open-ear shape sits outside your ear canal instead of plugging it. The detachable accessory ear clip is the headline feature — you can run them plain on a commute and then snap on the included diamond-studded earrings when you want them to read as jewelry. That's a genuinely unusual bit of flexibility, and it's the reason this pair stands out from the crowd of look-alike open-ear buds.
On the tech side, the sheet lists Bluetooth 5.4 with a 10-meter working range, a Φ10 mm speaker, and a balanced armature driver. There's ENC noise cancellation on the mic, which the listing says blocks around 90% of background noise for calls — that's a claim from the manufacturer, but ENC is a real and well-established technique for cleaning up voice pickup, so it's a sensible thing to expect on calls rather than in your music. The buds use 35mAh cells each with a 400mAh charging case, and charge time is listed at 1.5 hours. Supported profiles cover HSP, HFP, A2DP and AVRCP, which is the standard set for music plus hands-free calling.
Alfu Clip: Who It's For
The Alfu Clip takes the same open-ear clip concept and aims it squarely at active women. The butterfly ear clip is the styling hook, and the charging case is shaped like a small purse with a digital display — so instead of a vague blinking light, you get an actual number for the remaining power. It's a small thing that makes a real difference on a busy morning when you're deciding whether to grab the case.
The specs back up the sporty positioning. Bluetooth 6.0 is listed, which is a newer generation than the 5.4 on the soinfo pair, and the frequency range is given as 20 Hz – 20,000 Hz. The battery average life is 16 hours, delivered through the charging case, and the rating is IP5 splash-resistant — enough for sweat and light rain per the description. The enclosure is plastic and silicone, and the ear clip is described as small and ultra-light, with a fit that never enters the ear canal. Because nothing blocks your ears, you keep awareness of traffic and surroundings, which is exactly what you want on an outdoor run. There's also a one-year warranty listed, and the set includes ear cushions.
Buy them if you train, run or commute outdoors and want one pair that handles sweat, keeps you aware of your surroundings, and doesn't need charging anxiety. Skip them if clear hands-free calls in noisy places are your main use — no noise control is listed here at all, so the soinfo's ENC mic is the better bet for that job. Also skip if you want a case that slips into a pocket unnoticed: a purse-shaped case with a display is charming, but it's not the smallest thing to carry.
• Best for workouts and sweat → Alfu Clip. IP5 splash resistance plus a secure clip fit is the combination you want when you're moving.
• Best for phone calls in noisy places → soinfo Open Earphones. ENC noise cancellation on the mic is the only call-cleanup feature between the two.
• Best battery confidence → Alfu Clip. 16 hours total with a digital display on the case beats guessing.
• Best as a fashion piece you can change up → soinfo Open Earphones. Detachable ear clips mean one pair covers both understated and bold looks.
• Best for the newest Bluetooth generation → Alfu Clip. Bluetooth 6.0 versus 5.4 on the soinfo set.
• Best for the lightest feel and glasses wearers → soinfo Open Earphones. 4.5g per bud with a design explicitly described as fitting around glasses.
• Best as a ready-to-give gift → either, honestly. Both ship in presentation packaging; soinfo leans jewelry-box, Alfu leans purse-and-butterfly.
• Best for outdoor safety and awareness → tie. Both are open-ear, so neither seals your ear canal.
In my opinion, the Alfu Clip is the one I'd buy for most people, because splash resistance and a 16-hour total battery with a visible charge readout solve the two things that actually annoy you day to day. The open-ear clip fit, the awareness of your surroundings and the one-year warranty make it the more practical everyday companion. That said, if your day is built around calls and you want earbuds that read as jewelry you can swap in and out, I'd point you to the soinfo Open Earphones — the ENC mic and the detachable ear clips are genuinely useful, not gimmicks. Check the current price on Amazon before you commit, since value is the one thing specs can't tell you.
Alfu Clip. It's the only one of the two with an IP5 splash-resistance rating, and its description specifically calls out running, gym workouts and light rain, plus a fit that stays put with glasses on.
Yes — ENC noise cancellation is listed for the microphone, which is about making your voice clearer on calls rather than muting the world around you. The Alfu Clip lists no noise control at all.
Alfu Clip, at up to 16 hours of total battery life, and its charging case has a digital display showing remaining power. The soinfo pair uses 35mAh buds with a 400mAh case and a 1.5-hour charge time, but no total runtime is given.
Both are packaged for gifting. soinfo comes in a luxury gift box with diamond-studded earrings; Alfu pairs butterfly ear clips with a purse-style case. Pick soinfo for a jewelry-first gift, Alfu for someone who'd use them at the gym.
