If you want a single pair of headphones that a teen can wear all day, fold up, and use wirelessly or with a cable, choose PowerLocus Over-Ear; if you need something small, cute, and pocketable that disappears into a backpack and never tangles, choose Fsjun Cat Earbuds. Both are aimed at the same buyer — a teenager, or a parent shopping for one — but they solve completely different problems, and picking the wrong one is the fastest way to end up with a gift that sits in a drawer. Below I break down what each one actually does well, where each one falls short, and which one I would pick depending on how your teen listens.
• PowerLocus Over-Ear — biggest strength: a full over-ear design with 40mm dynamic drivers, Bluetooth 5.3, a 3.5mm wired fallback, and a foldable build with a protective carrying bag. It is the more versatile and more grown-up-feeling of the two.
• PowerLocus Over-Ear — biggest trade-off: it is a bulky, 9.6-ounce headphone in a single Gold finish, and the 15-hour battery life means it needs charging far more often than a case-based earbud setup.
• Fsjun Cat Earbuds — biggest strength: a genuinely pocketable in-ear set with a cat-themed LED charging case, Bluetooth 5.4, touch controls, and up to 28 hours of total playtime from the case.
• Fsjun Cat Earbuds — biggest trade-off: no wired option at all, no noise control, and a shorter half-year warranty — it is a fun accessory first and a serious listening tool second.
• Who each is for: PowerLocus Over-Ear suits the teen who wants one do-everything headphone for music, gaming, calls and travel; Fsjun Cat Earbuds suit the teen who wants something small, stylish and easy to carry that also makes a great gift.
The PowerLocus Over-Ear is the more traditional of the two, and that is exactly its appeal. It uses 40mm dynamic drivers with a 110Hz–20,000Hz frequency range and a 32-ohm impedance, tuned toward deep bass and what the brand describes as dynamic power sound. For a teen listening to pop, hip-hop, gaming audio or YouTube videos, that is a sensible tuning — it is not trying to be a reference monitor, it is trying to sound full and enjoyable at normal volumes.
The real story here is flexibility. This headphone works over Bluetooth 5.3 with roughly a 10-meter range, but it also accepts a 3.5mm aux cable, so your teen can keep listening on a wired connection when the battery is flat. It also supports FM radio and Micro SD/TF card playback, which is unusual at this tier and genuinely useful for a kid who wants offline music without tying up a phone. It can pair with two devices at once, so switching between a laptop and a phone is less annoying than it sounds.
Comfort and durability are clearly priorities in the design. The earcups use soft protein foam with a faux leather cover, the sides extend to fit both adults and children, and the whole thing folds down into the included protective carrying bag. At 9.6 ounces it is not featherweight, but it is a normal over-ear weight. The built-in microphone uses noise-cancelling CVC technology for calls, and the package includes the headphone, the cable, the case and a USB charging cable. Battery life is listed at 15 hours with a 2.5-hour charge time, and the warranty runs a full 24 months.
Who should buy it: a teen who wants one headphone for everything — homework, bus rides, gaming, phone calls and family trips — and who would rather carry a bag than a case. Who should skip it: anyone who wants something invisible in a pocket, anyone who dislikes on-ear pressure over long sessions, and anyone set on a color other than Gold.
The Fsjun Cat Earbuds go after a completely different instinct. These are true in-ear buds with 13mm dynamic drivers, a 20Hz–20,000Hz range and 32-ohm impedance, running Bluetooth 5.4 with a stated transmission range of up to 50 feet. That is a wider range than the PowerLocus on paper, and Bluetooth 5.4 plus Class 2 transmission power is aimed squarely at stable connections with minimal dropouts.
The headline feature, though, is the case. It is a cat-themed design in Purple with a built-in LED battery display, and it is the reason a teen will actually want to carry these. Total playtime is quoted at up to 28 hours with the case and about 5 hours per charge, with a 3-hour charge time. For a school day plus an evening, that is more than enough, and the LED readout means your teen can see remaining power instead of guessing.
Controls are touch-based: tap to play or pause, skip tracks, take calls, or trigger a voice assistant. They work with Siri and other assistants and connect across iOS, Android and Windows. The buds are designed to sit naturally in the ear canal for a secure fit, and at 35 grams for the set they are dramatically lighter than an over-ear. The package includes the earbuds, a Type-C charging cable and a manual.
Side-by-Side: Which Should You Choose?
• Best for battery flexibility → Fsjun Cat Earbuds. Up to 28 hours with the case and an LED power display beats a single 15-hour charge.
• Best for never running out of power → PowerLocus Over-Ear. The 3.5mm aux cable means music keeps playing at 0% battery.
• Best for comfort over long sessions → PowerLocus Over-Ear. Over-ear protein foam cups spread pressure instead of pushing into the ear canal.
• Best for portability → Fsjun Cat Earbuds. 35 grams in a pocket-sized cat case versus a 9.6-ounce folding headphone and bag.
• Best for calls and voice assistants → Fsjun Cat Earbuds. Touch controls, assistant activation, and Bluetooth 5.4 with up to 50 feet of range.
• Best for offline and legacy sources → PowerLocus Over-Ear. FM radio and Micro SD/TF card playback are things the earbuds simply cannot do.
• Best for a gift that lands → Fsjun Cat Earbuds. The cat-themed design and pastel-purple case are the whole point for the right teen.
• Best for long-term peace of mind → PowerLocus Over-Ear. A 24-month warranty against a half-year one is a meaningful difference for teen use.
My Verdict
Yes — the extendable sides fit both adults and children, the cups are soft protein foam, and the 3.5mm wired mode is a real safety net for a teen who forgets to charge things.
No. They are wireless only, with no headphone jack, so all listening depends on the battery. Expect roughly 5 hours per charge and up to 28 hours with the case.
The PowerLocus uses larger 40mm drivers tuned for deep bass; the Fsjun uses 13mm drivers with a balanced tuning. Larger drivers generally move more air, but fit matters more than size for in-ears — the Fsjun's in-canal seal can make small drivers sound fuller than expected.
