How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, fully submersible earbud you can actually swim laps with, choose AGPTEK IPX8; if you need a wireless, open-ear bud that keeps you aware of traffic and lasts through a whole week of workouts, choose WEIBEIQI Open Ear.
These two get compared a lot because both are pitched at swimmers, runners and gym people. But they solve completely different problems. One is a corded, sealed in-ear bud built to go underwater. The other is a hook-style wireless bud built to sit outside your ear canal and never leave you stranded without a charge. Below is how I'd split them, based on what each design and spec sheet actually tells a buyer.
• AGPTEK IPX8 — biggest strength: a genuine IPX8 submersion rating, meaning the inner nano-coating is specified to survive 1.5 metres of water for 30 minutes, plus a coiled cable that resists tangling and a bundled 1 m extension cable for reaching a device on the poolside.
• AGPTEK IPX8 — biggest trade-off: it's wired and in-ear. You're tethered to a 3.5 mm jack, there's no Bluetooth and no built-in battery, so it only works with devices that still have a headphone port.
• WEIBEIQI Open Ear — biggest strength: fully wireless with Bluetooth 5.4, an open hook design that leaves your ear canal clear, and a charging case that extends the buds to a claimed 60 hours in total.
• WEIBEIQI Open Ear — biggest trade-off: it's IPX7, not IPX8, so it handles sweat and rain but isn't specified for being submerged. The open fit also means less passive noise isolation by design.
• Who each is for: AGPTEK IPX8 for lap swimmers and anyone who wants zero charging anxiety; WEIBEIQI Open Ear for runners, cyclists and gym users who want wireless freedom and situational awareness.
The AGPTEK IPX8 is one of the few earbuds where the name isn't marketing fluff. The IPX8 rating means the internal nano-coating is designed to handle immersion — the spec sheet puts that at 1.5 metres for up to 30 minutes — and that single fact drives everything about who should buy it. If you swim laps, this is the category of product you want, because almost nothing else survives being fully underwater.
Sound-wise, the drivers are 10 mm dynamic units with a 20 Hz–20,000 Hz frequency range, 32 ohm impedance and a stated sensitivity of 32 ohm, with sound-isolation noise control and in-line touch controls. That's a conventional wired-earbud setup — nothing exotic, but it's the right architecture for the job, because there's no battery to run down mid-swim and no wireless dropouts when your head goes under.
Who should buy it: lap swimmers, triathletes in training, people who shower or bathe with music, and anyone who still keeps a 3.5 mm device around and wants an earbud that simply never needs charging. Who should skip it: if you've moved fully to a phone without a headphone jack, or you want to take calls on the move, this isn't the tool — the wired connection and lack of Bluetooth are hard limits, not quirks.
WEIBEIQI Open Ear: Who It's For
The WEIBEIQI Open Ear is the opposite philosophy. It's a wireless, hook-style bud — model YYK-Q16 — built around staying outside your ear canal entirely. The design brief here is comfort and awareness rather than isolation. Because nothing is plugged into the canal, you keep hearing traffic, gym announcements and the person next to you, and the spec sheet specifically calls out that the shape avoids the long-wear ear pain that sealed buds can cause.
The battery story is the headline. WEIBEIQI rates the buds at 10 hours of continuous playback, with a charging case that adds roughly 40 more for a total of about 60 hours, and a 1-hour Type-C charge refills the case. There's an LED digital display on the case so you can see the remaining power instead of guessing — a small thing that genuinely reduces the "are these dead?" anxiety before a run. Bluetooth 5.4 handles the connection with a stated range of up to 15 metres, and the low-latency link is aimed squarely at video, gaming and calls, which is where older Bluetooth versions tend to show lip-sync lag.
On hardware, WEIBEIQI lists a 14.2 mm vibration driver for bass and stereo output, a 0.7 mm memory-flex titanium alloy frame that bends to your ear shape, and medical-grade skin-friendly silicone. Weight is 0.26 oz, which is genuinely light for a hook design — the kind of number that matters on mile ten of a long run. Protection is IPX7, so sweat, rain and splashes are fine, but it isn't rated for swimming the way the AGPTEK is. There's a built-in microphone for calls and touch controls on the bud itself.
Who should buy it: runners, cyclists, walkers and gym users who want wireless freedom, long battery life and to stay aware of their surroundings. Who should skip it: swimmers who need real submersion protection, and anyone who wants strong noise isolation — the open design deliberately lets the world in.
• Best for swimming → AGPTEK IPX8. IPX8 with a 1.5 m / 30-minute immersion spec versus IPX7 splash-and-sweat protection.
• Best for battery freedom → WEIBEIQI Open Ear. 10 hours per charge plus a case that extends to roughly 60 hours total, versus a wired bud that needs no battery at all but must stay plugged in.
• Best for situational awareness → WEIBEIQI Open Ear. The open hook design keeps your ear canal clear; the AGPTEK's in-ear seal plus sound isolation does the opposite.
• Best for long-wear comfort → WEIBEIQI Open Ear. 0.26 oz with a titanium alloy frame and skin-friendly silicone, designed to avoid canal pressure over hours.
• Best for simple, no-charging reliability → AGPTEK IPX8. No pairing, no battery, no dropouts — plug into a 3.5 mm port and go.
• Best for calls and video → WEIBEIQI Open Ear. Built-in mic plus Bluetooth 5.4 with low-latency tuning; the AGPTEK has no microphone at all.
• Best for tangled-cable haters who still want wires → AGPTEK IPX8. The coiled cord plus the 1 m extension cable is a smarter wired setup than most.
• Best for water-adjacent but not underwater → WEIBEIQI Open Ear. IPX7 covers rain and heavy sweat, which is plenty for outdoor training.
If I had to pick one, I'd buy the WEIBEIQI Open Ear — for the simple reason that it fits more of my week. Most workouts happen on land, and the combination of 60-hour total battery, an open fit that keeps me safe near traffic, and Bluetooth 5.4 with a mic covers running, cycling, calls and gym sessions. The AGPTEK IPX8 is the better product for exactly one job, and it does that job better than almost anything: actual swimming. If laps are your main sport, buy the AGPTEK without hesitation. If they're a side activity, the WEIBEIQI is the more useful everyday bud. Either way, check the current price on Amazon before deciding, since the gap between them moves around.
Yes — that's its whole purpose. It carries an IPX8 rating, with the nano-coating specified to handle immersion in 1.5 metres of water for 30 minutes. It also ships with M/L swimming ear tips alongside standard S/M/L tips for normal listening.
I'd avoid full submersion. It's rated IPX7, which covers sweat, rain and splashes, but it isn't specified for being held underwater the way the AGPTEK IPX8 is. For running and gym work it's more than enough protection.
No, and that's intentional. The open-ear hook design leaves your ear canal clear so you stay aware of traffic and surroundings. The spec sheet lists noise control as none. If you want isolation, the AGPTEK's in-ear seal and sound-isolation technology is the better fit.
It depends on the job, not the spec count. The AGPTEK IPX8 gives you a sealed, submersible wired bud with no battery to die. The WEIBEIQI Open Ear gives you wireless freedom, a mic, and roughly 60 hours of total playtime. Match the one to how you'll actually use it, then check the latest price on Amazon for both.
