• PowerLocus biggest strength: Dual-mode design — Bluetooth 5.3 wireless plus a 3.5 mm aux jack, with 40 mm dynamic drivers, a built-in noise-reduction mic, and a foldable over-ear frame with memory-protein foam earcups.
• PowerLocus biggest trade-off: It's a heavier, closed over-ear headphone (roughly 150–165 g) that sits on your ears rather than leaving them open, so it blocks surrounding sound instead of letting it in.
• Jiunai biggest strength: Open-ear wired design with 15° adjustable over-ear hooks, a 90° right-angled 3.5 mm plug, 16 mm dynamic drivers, an in-line mic and controls, and a cord clip to cut cable drag.
• Jiunai biggest trade-off: Wired only — there is no Bluetooth and no battery, so you're tethered to whatever has a 3.5 mm jack.
• Pick PowerLocus if you want one headphone for flights, commuting, calls and desk work, and you value wireless freedom with an aux fallback.
• Pick Jiunai if you want a featherweight wired earbud for running, gym sessions, commuting or long calls where you still need to hear traffic and coworkers.
PowerLocus is built around flexibility. You get Bluetooth 5.3 for wireless listening and a 3.5 mm jack for wired listening, so the same pair covers a phone, tablet, laptop or an in-flight entertainment system. The 40 mm dynamic drivers and 32 ohm impedance are standard over-ear territory — enough to drive cleanly from a phone or a laptop headphone output without extra amplification. The spec sheet lists a 20 Hz–20,000 Hz frequency range, 15 hours of music playback and roughly 14–15 hours of talk time from a 400 mAh battery, with a 2.5-hour charge time. Bluetooth range is quoted at around 36 feet, which is generous enough to leave your phone on a desk and walk around a room.
Comfort is clearly the design priority. The earcups use memory-protein foam with a leather finish, the frame folds and stretches, and the whole thing ships with a protective case, a USB-C charging cable and the aux cable. At about 150–165 g it's light for an over-ear, and the fold-flat build makes it easy to toss in a bag. The noise-reduction microphone handles hands-free calls, and the controls cover call management.
Who should skip it: if you run or train hard and need to hear your surroundings, or if you simply don't want another battery to charge, this isn't the right shape or category. It's a closed over-ear, so it isolates rather than lets the world in.
Jiunai Open Ear: Who It's For
Jiunai solves a different problem: staying put. The 15° adjustable ergonomic over-ear hooks are designed to lock gently around the ear so the bud doesn't shift during high-intensity workouts, runs or commutes, and a small cord clip attaches to your clothing to reduce cable drag and the rustle that comes with it. The 3.5 mm plug is set at a 90° right angle, which is a genuinely practical detail — it keeps the cable tucked close to the device instead of sticking straight out and snagging.
The audio side is a 16 mm dynamic driver with 16 ohm impedance and 126 dB sensitivity. Low impedance plus high sensitivity means it's easy to drive from almost anything with a headphone jack — a phone, an iPod, a CD player, a laptop, or an airplane seat. The open-ear design is the point: you hear your music and your surroundings at the same time, which matters on a road run, in a shared office, or when someone is trying to get your attention. In-line controls with a microphone cover calls and playback without reaching for your phone.
The build mixes ABS, silicone and TPE — sensible materials for something meant to flex and survive sweat — and it ships with replacement ear tips and a zipper carry case. Warranty is listed at 3 months, which is short compared to PowerLocus's 24-month coverage, so treat this as an active-use accessory rather than a long-term daily driver.
Who should buy it: runners, gym-goers, cyclists, commuters, students, office and remote workers who want lightweight wired earphones that stay put and keep them aware of traffic, announcements and coworkers. Who should skip it: anyone who wants wireless freedom, noise isolation, or a single pair for flights and focused listening.
• Best for wireless freedom → PowerLocus Over-Ear Headphones. Bluetooth 5.3 with roughly 36 feet of range and 15 hours of playback.
• Best for wired-only simplicity → Jiunai Open Ear. No battery, no pairing, no charging — plug the 3.5 mm jack in and go.
• Best for long listening sessions → PowerLocus Over-Ear Headphones. Memory-protein foam earcups and a foldable, stretchable headband built for extended wear.
• Best for running and the gym → Jiunai Open Ear. 15° adjustable ear hooks plus a cord clip designed to stop the bud from shifting.
• Best for staying aware of your surroundings → Jiunai Open Ear. The open-ear design deliberately leaves your ear canal unblocked.
• Best for flights, commuting and calls → PowerLocus Over-Ear Headphones. Sound isolation, a noise-reduction mic and a protective travel case.
• Best for low-power devices → Jiunai Open Ear. 16 ohm impedance and 126 dB sensitivity make it easy to drive from almost any 3.5 mm source.
• Best for build and support confidence → PowerLocus Over-Ear Headphones. A 24-month warranty versus 3 months.
In my opinion, PowerLocus Over-Ear Headphones is the better buy for most people, because it does more jobs. The aux cable means it never becomes useless when the battery runs out, and Bluetooth 5.3 means you're not stuck with a wire the rest of the time. Foldable over-ear comfort, a protective case, a mic for calls and a 24-month warranty round it out as a genuine all-rounder.
If your priority is running, sweating and hearing the world around you, I'd take Jiunai Open Ear instead — that's what the open-ear hooks and cord clip are built for. Just go in knowing it's wired-only with a 3-month warranty. Check the current price on Amazon for both before you commit.
FAQ
how to make aux cable with headphones
how to use wired headphones without headphone jack
You need an adapter, because a 3.5 mm plug needs a 3.5 mm socket. If your phone or laptop only has USB-C or Lightning, use the matching dongle or adapter for that port. PowerLocus Over-Ear Headphones give you an easier route here: it pairs over Bluetooth 5.3, so you can skip the jack entirely and only use the aux cable on devices that actually have one.
how do i connect my wired headphones to my phone
With Jiunai Open Ear, just push the 3.5 mm plug into the phone's headphone jack — the 90° angled connector keeps the cable flat against the phone. If your phone has no jack, use a USB-C or Lightning adapter. With PowerLocus Over-Ear Headphones you have two options: slide the power switch to pair over Bluetooth, or connect the included aux cable to the 3.5 mm jack.
Only PowerLocus Over-Ear Headphones has a battery — a 400 mAh cell rated for about 15 hours of music and 14–15 hours of talk time, charging in about 2.5 hours via USB-C. Jiunai Open Ear has no battery at all; it's fully passive and runs entirely off the 3.5 mm connection, so there's nothing to charge.
