How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear, wireless set that keeps you aware of your surroundings while you move between classes, choose Anker Soundcore V20i; if you need a plug-in wired pair with real in-ear isolation and a cable that never needs charging, choose BZINK H89. Both are built for school, but they solve completely different problems — one is for staying tuned in to the world, the other for shutting it out.
• Anker Soundcore V20i — biggest strength: open-ear design with four adjustable hook positions, so nothing plugs your canal and you keep hearing what's around you.
• Anker Soundcore V20i — biggest trade-off: it's fully wireless with no headphone jack, so it needs charging and a Bluetooth source.
• BZINK H89 — biggest strength: wired 3.5 mm connection with in-ear sound isolation and three sizes of eartips for a sealed, stable fit.
• BZINK H89 — biggest trade-off: the cable ties you to your device, and it has no battery, no Bluetooth, and no open-ear awareness.
• Who Anker Soundcore V20i is for: students who move around campus, want to hear announcements and traffic, and hate swapping batteries or cables.
• Who BZINK H89 is for: students at a desk or laptop who want isolation, a reliable plug-in connection, and zero charging anxiety.
The V20i is an open-ear design, which is the whole point of it. Instead of pushing a tip into your ear canal, it hangs on adjustable hooks that rotate into four positions, so you can dial in the fit that stays put for your ears. In my opinion that's the standout feature here — the adjustability is what makes open-ear actually workable for long stretches, because you're not fighting a one-size shape all day. Sound comes from 16 mm dynamic drivers with titanium-coated domes and Anker's BassUp processing, and there's a customizable EQ if you want to tweak the balance.
For school use, the appeal is awareness. You can walk a hallway, cross a parking lot, or sit in a lecture hall and still hear your surroundings. That's also why open-ear designs get searched as open ear earbuds for school — they're the pick when you don't want to be sealed off from the room. The four-mic array with AI enhancement handles calls, the touch controls keep things buttonless, and the IP55 rating means sweat and light rain aren't a dealbreaker. Battery-wise you get about 8 hours per charge and up to 36 hours with the case, and the case itself tops up in roughly 2.5 hours. Bluetooth 5.4 with multipoint lets you stay connected to two devices at once, which is genuinely handy if you hop between a phone and a laptop.
Who should skip it? If your priority is blocking out a noisy room — a loud cafeteria, a crowded bus — this isn't the tool. There's no noise control at all here, and open-ear by definition lets the world in. Someone who wants deep isolation, or who wants to plug into a 3.5 mm jack with no charging involved, should look elsewhere.
The H89 goes the opposite direction. It's a wired in-ear monitor with a 3.5 mm plug, so it works with anything that has a headphone jack — a laptop, a desktop, a tablet, an older phone. No pairing, no battery, no charging case. You plug it in and it plays. The housing is a high-density PC plastic that BZINK describes as smooth and lightweight, and the ergonomic in-ear shape is built to sit without pressure. You also get three sets of soft eartips, which matters a lot if you've ever struggled to get a consistent seal.
Sound is handled by an 11 mm PET polymer diaphragm, tuned for fuller bass, a wide sound field, and clear vocals. Impedance is 20 ohm with 99 dB sensitivity, so it'll get loud easily off a phone or laptop jack. The noise control here is passive sound isolation — the eartip seal itself. That's the real difference from the Anker pair: this one is designed to keep sound in and the room out. Remote media controls sit on the cable, so you're not reaching for your device to pause. It carries a 1-year warranty.
Who should skip it? Anyone who wants to move around freely. The cable is a leash, and there's no Bluetooth option at all. If you want to hear traffic, announcements, or a professor while you walk, the isolation works against you. And if your device has no 3.5 mm jack, this simply won't connect without an adapter.

For school, I'd buy the Anker Soundcore V20i. In my opinion, the open-ear design is the smarter fit for a campus day — you keep your awareness, you're not tethered to a cable, and the adjustable hooks plus 36-hour case life mean it just works from morning to evening. The BZINK H89 is a genuinely good wired option if you're parked at a laptop and want isolation and a jack that never needs charging, and its price is low enough that you should just check the current price on Amazon to judge the value yourself. But if you're moving between classes, the V20i wins.

The trick is the eartip, not the cable. The BZINK H89 ships with three sets of soft eartips, so try each size and pick the one that creates a light seal without pressure. A proper seal both holds the bud in place and improves the isolation the H89 is built around.
how to put earbuds in your ear
For an in-ear model like the H89, gently pull the top of your ear up and back, slide the tip into the canal, then let the ear settle. For an open-ear model like the Anker Soundcore V20i, you don't insert anything — you hook it over the ear and rotate the hook through its four positions until it feels stable.

Fit is everything, and both products address it differently. The H89 relies on the right eartip size for a sealed, in-canal hold, while the V20i uses four adjustable hook positions to lock onto the outer ear. Pick the adjustment that removes pressure points — that's usually the one that stays put.

The same principle applies across brands: a correct eartip seal beats any trick. If you're comparing to a wired set, note that the H89 gives you three tip sizes to work with, while an open-ear design like the V20i skips the canal entirely and uses adjustable hooks instead — so the "staying in" problem is solved by shape rather than tips.
