• Sanluba's biggest strength: a 3.5mm gold-plated wired plug with an in-line remote and mic — zero charging, zero pairing, works with basically anything that still has a headphone jack.
• Sanluba's biggest trade-off: you're tethered to a cable, and there's no battery case or wireless freedom. It's old-school by design, and that's the point.
• YEAHBOX Popo Air Open's biggest strength: an open-ear clip-on design that doesn't block your ear canal, plus Bluetooth 6.0 and up to 18 total hours with the charging case.
• YEAHBOX Popo Air Open's biggest trade-off: it needs charging and a Bluetooth source, and the open-ear fit means you're trading some isolation for comfort and awareness.
• Pick Sanluba if you want simplicity, a cable, and universal compatibility. Pick YEAHBOX if you want wireless freedom and all-day comfort without shoving anything into your ear canal.
The Sanluba set leans hard into one idea: keep it simple and keep it wired. The 3.5mm plug is gold-plated and described as rust-resistant, which matters because a plug is the first thing to corrode on cheap earbuds. There's no Bluetooth, no battery, no pairing screen — you plug in and you're listening. For anyone who's tired of "my earbuds died mid-call" moments, that's the whole appeal.
The in-line remote is the practical hero here. A high-sensitivity mic filters ambient noise for calls, and the multifunction remote handles answer/reject, play/pause, volume, and track skipping without touching your phone. If you spend your day in Zoom, Skype, or online classes and language tests, having physical buttons you can find by feel is genuinely useful. The ergonomic 45° inclined design and roughly 3-gram-per-ear weight are built for long sessions — commuting, running, or a full workday — and the sound-isolation design reduces leakage while tightening up bass response.
Who should skip it? Anyone who's already cut the cord. If your phone dropped the headphone jack, or you want to move around a gym without a cable snagging, this isn't your product. The Sanluba is for the person who values a dependable, always-ready wired connection over wireless convenience — and who likes that the package includes two sets.
YEAHBOX goes the opposite direction. The Popo Air Open is an open-ear clip-on: it hooks over your ear without plugging the canal, so there's no pressure and no ear fatigue over long stretches. That clip-on shape is the reason people reach for open-ear buds in the first place — you can wear them for hours, and you stay aware of traffic, coworkers, or a doorbell in a way that sealed in-ears never allow.
Inside, dual dynamic drivers aim for balanced HiFi sound with rich bass, detailed mids, and clean highs, and a sealed acoustic design keeps your music from leaking into the room around you — handy in an office or library. Calls get a dual-mic setup with background noise reduction, which is the spec you want if you're on Teams or Zoom regularly. Connectivity is Bluetooth 6.0 with a stated 10-meter range and low-latency pairing, and the rated battery life is up to 6 hours per charge, extended to about 18 hours with the compact charging case.
The IPX5 rating is the workout-friendly detail: sweat and light rain are fine. It's also adult-oriented and comes with a one-year manufacturer warranty. Who should skip it? If you want maximum isolation, deep passive blocking of train noise, or you refuse to manage a battery, the open-ear approach works against you — by design you hear more of the world. And you'll need a Bluetooth source; there's no jack.
• Best for wireless freedom → YEAHBOX Popo Air Open. Bluetooth 6.0, a 10-meter range, and a charging case mean no cable at all.
• Best for "it just works" reliability → Sanluba Headphones Earphones. No battery to drain, no pairing — plug into any 3.5mm jack and go.
• Best for all-day comfort without ear-canal pressure → YEAHBOX Popo Air Open. The open-ear clip design avoids the plugged-up feeling entirely.
• Best for loud, isolating listening → Sanluba Headphones Earphones. Its sound-isolation design and in-ear seal push outside noise down; the open-ear YEAHBOX deliberately lets it in.
• Best for workouts and light rain → YEAHBOX Popo Air Open. IPX5 handles sweat and splashes; the Sanluba is a wired set better suited to stationary listening.
• Best for calls without a phone in hand → YEAHBOX Popo Air Open for wireless dual-mic calls, Sanluba if you prefer a physical in-line remote you can press by feel.
• Best for older devices, consoles, and MP3 players → Sanluba Headphones Earphones. The 3.5mm plug covers iPhones, iPads, Android phones, gaming consoles, and MP3/MP4 players.
• Best for battery-free, tangle-resistant durability → Sanluba Headphones Earphones. TPE cable construction and bending-test durability, with no charging case to lose.
My Verdict
No — that's the opposite of what you want. The YEAHBOX relies on a battery and case, rated at up to 6 hours per charge and about 18 hours total. If charging annoys you, the wired Sanluba never needs power at all.
They connect only through the 3.5mm plug, so a phone without a headphone jack won't work directly. They're compatible with devices that have a 3.5mm port — iPhones and iPads with a jack, Android phones, laptops, PCs, gaming consoles, and MP3/MP4 players.
By design, the YEAHBOX Popo Air Open is built for that — its open-ear clip doesn't block the ear canal, so there's no pressure or fatigue. The Sanluba is also lightweight at about 3 grams per ear, but it's an in-ear fit, so it seals the canal rather than sitting outside it.
The YEAHBOX Popo Air Open is rated IPX5, meaning it resists sweat and light rain, which suits workouts and commutes. The Sanluba is a wired in-ear set with no stated water-resistance rating, so I'd keep it away from heavy sweat or rain.
