• ZKBSIAXD Earbuds — biggest strength: a 60-hour total runtime (8 hours per charge plus 52 more in the case) with an LED display that shows the exact battery percentage of both the buds and the case, so you are never guessing before a long session.
• ZKBSIAXD Earbuds — biggest trade-off: the in-ear design physically seals your ear canal, which means you hear less of what is going on around you — not ideal on a busy bank or a shared boat.
• STUPIDYIN Open Ear Headphones — biggest strength: the ear-hook, open-ear shape sits over the ear without blocking the canal, so ambient sound comes through while 14.2mm dynamic drivers push the audio in.
• STUPIDYIN Open Ear Headphones — biggest trade-off: 30 hours total playtime (6–7 hours per charge) is roughly half the ZKBSIAXD runtime, and open-ear designs inherently leak more sound into the space around you.
• Who each pick is for: ZKBSIAXD for the angler who wants long, private listening sessions and a locked-in fit; STUPIDYIN for the angler who wants to stay aware of the environment and wears headphones for hours without pressure in the ear.
The ZKBSIAXD Earbuds are built around two ideas: long runtime and a secure seal. On paper that is a 10mm dynamic driver covering a 20Hz–20kHz frequency range, Bluetooth 5.4, and a claimed 15-meter wireless range. The frequency range is the standard full-band spec you want for music, and the 10mm driver is a sensible size for a punchy, balanced in-ear sound rather than a thin one.
The battery story is where these stand out. Eight hours on a single charge, then 52 more from the case, for a 60-hour total. That is a genuinely long runway — enough for a multi-day trip without hunting for a wall outlet. The LED digital screen on the case showing the exact percentage for both the earbuds and the case is the kind of detail that matters more than it sounds: you know before you leave whether you are topped up.
For fishing specifically, the in-ear fit with three sizes of silicone tips (S/M/L) is a real advantage when you are moving — casting, walking a shoreline, working a boat deck. A sealed tip stays put and it also mutes wind and water noise, so a podcast or a call comes through cleanly. The noise-cancelling microphone helps on the call side if you take a work call mid-trip, and IPX4 means sweat and light rain are not a problem.
Who should buy it: anyone who wants long battery life, a private listening experience, and a fit that does not shift during activity. Who should skip it: if your priority is hearing your surroundings — other boats, traffic at the ramp, someone calling your name — the sealed in-ear design works against you, and you should look at open-ear instead. The touch controls are sensitive and easy to use, but they do take a session or two to learn.
The STUPIDYIN Open Ear Headphones take the opposite approach. The S25 uses an ergonomic ear-hook design that rests over the ear without entering the canal, and the whole point is awareness. You get your music, and you also get the ambient world — footsteps, voices, a car pulling up behind you. For anything outdoors, that is not a gimmick, it is a safety feature.
The audio side is more interesting than you might expect from an open-ear set. The 14.2mm dynamic drivers are noticeably larger than the 10mm units in the ZKBSIAXD, and larger drivers generally move more air, which is why STUPIDYIN can credibly claim bass that most open-ear designs lack. Directional audio transmission is meant to focus sound toward your ear and reduce leakage, though with an open design some leakage is unavoidable — that is physics, not a defect.
Battery is 30 hours total with 6–7 hours per charge, and the case has a glossy finish with a real-time LED display from 0 to 100%. That is a clear step down from the ZKBSIAXD's 60 hours, but for daily commutes, gym sessions and shorter outings it is more than adequate. Bluetooth 5.4 with dual microphones and noise-reduction algorithms handles calls well, and the 10-meter rated range is fine for normal use, though shorter than the ZKBSIAXD's 15 meters.
The comfort argument is the strongest one. Because nothing presses into the ear canal, all-day wear is genuinely pain-free for people who find in-ears irritating after an hour or two. The flexible hooks hold the buds in place during running, hiking and casting. The beige, plastic build is understated rather than flashy, and the package includes a cable and user manual.
Who should buy it: outdoor athletes, runners, cyclists, and anyone who wants music while staying aware of their surroundings — including anglers who fish near traffic, other people, or moving water. Who should skip it: if you want isolation, deep bass in a sealed environment, or the longest possible battery life, the ZKBSIAXD is the better fit.
• Best for battery life → ZKBSIAXD Earbuds. 60 hours total (8 + 52) versus 30 hours (6–7 per charge) is a decisive gap for multi-day trips.
• Best for staying aware of your surroundings → STUPIDYIN Open Ear Headphones. The open-ear hook design leaves the canal clear, so ambient sound comes through.
• Best for a secure, isolated fit during movement → ZKBSIAXD Earbuds. Three sizes of silicone tips seal the ear and stay in place while casting, walking or working a deck.
• Best for all-day wear without ear fatigue → STUPIDYIN Open Ear Headphones. Nothing presses into the canal, which is the main reason people abandon in-ears.
• Best for bass from an open design → STUPIDYIN Open Ear Headphones. The 14.2mm drivers are the larger units here, and larger drivers move more air.
• Best for private listening → ZKBSIAXD Earbuds. A sealed in-ear fit keeps your audio to yourself; open-ear designs always leak some sound outward.
• Best for wireless range → ZKBSIAXD Earbuds. A rated 15 meters versus 10 meters on the STUPIDYIN.
• Best for call clarity in a noisy spot → both, with a caveat. Each has noise-reducing microphones, but the ZKBSIAXD's sealed fit also blocks incoming noise for you.
If I were buying for fishing, I would take the STUPIDYIN Open Ear Headphones. Fishing happens outdoors, often near water, other people or traffic, and being able to hear what is around you while you listen is worth more than an extra 30 hours of battery. The open-ear hook design is also more comfortable for a long day on the bank, and the 14.2mm drivers mean you are not sacrificing much on sound.
That said, my recommendation flips if your trips are long, your priority is battery life, or you want a sealed, private listening experience — in that case the ZKBSIAXD Earbuds are the smarter buy, and the 60-hour total runtime with the percentage display is genuinely hard to argue with. In my opinion, the deciding question is simple: do you want to hear the world, or shut it out?
For most fishing situations, yes — in my opinion. Open-ear designs leave your ear canal clear so you can hear traffic, other anglers and moving water, which matters for safety outdoors. In-ear models like the ZKBSIAXD give you isolation and a stronger seal, which is better if you want to block the world out.
ZKBSIAXD. It offers 8 hours on a single charge plus 52 hours in the case for 60 hours total, while the STUPIDYIN S25 gives 6–7 hours per charge and 30 hours total. Both cases have LED displays showing the remaining percentage.
They should hold up better than most open-ear sets because they use 14.2mm dynamic drivers — larger than the 10mm drivers in the ZKBSIAXD — and larger drivers move more air. Directional audio transmission also aims sound toward your ear, though some leakage is normal with any open design.
Yes. Both use Bluetooth 5.4 with noise-reducing microphones, and both support touch controls. The ZKBSIAXD seals your ear, so you also hear less background noise yourself, while the STUPIDYIN keeps you aware of your surroundings. Neither is a wired set, so latency depends on your device.
Both are rated IPX4, which covers sweat and light rain. Neither is rated for submersion, so do not wear either pair while swimming or if you expect to be fully soaked.
