How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a foldable, kid-friendly over-ear pair that can also run wired when the battery dies, choose PowerLocus Over-Ear; if you need marathon battery life and a tighter on-ear fit with speedy USB-C charging, choose Amazon Renewed JBL Tune 510BT. That's the short version. The longer version matters a lot when you're shopping teen headphones, and it matters even more if the person wearing them is chasing good sound — the kind of listener who reads about head phones for audiophiles and wonders whether an over-ear or an on-ear design gets closer to that ideal. Neither of these is a reference-grade rig. But each one solves a different problem, and picking the wrong one is the whole reason you're stuck.
• PowerLocus Over-Ear — biggest strength: a true over-ear fit with protein-foam ear cushions, a foldable frame with stretchable sides, and four ways to listen (Bluetooth, 3.5mm aux, FM radio, microSD).
• PowerLocus Over-Ear — biggest trade-off: roughly 15 hours of playback per charge and a 2.5-hour charge time, so heavy daily users will be plugging in often.
• Amazon Renewed JBL Tune 510BT — biggest strength: up to 40 hours of wireless playtime, a 2-hour charge over USB-C, and a 5-minute top-up that adds about 2 hours of music.
• Amazon Renewed JBL Tune 510BT — biggest trade-off: it's an on-ear design with no audio jack at all, so once the battery is empty there's no wired fallback, and it's a renewed unit covered by a 90-day limited warranty rather than a new-product one.
• Who each is for: PowerLocus for a teen who wants one pair for the bus, the house and the flight, with a cable as a safety net; the renewed JBL for a teen who mostly streams, hates charging cables, and wants the lightest possible thing on their head.
The PowerLocus P1 is built around flexibility. It's an over-ear headphone, which means the cushions sit around the ear rather than pressing on it — a meaningful difference for a teenager who wears headphones for three hours of homework and then two hours of gaming. The earpads are soft protein foam wrapped in faux leather, and the sides stretch, so the same pair fits a younger kid and an adult. It folds up too, and it ships with a protective carrying bag, which is the difference between a pair that survives a backpack and one that doesn't.
Where it gets interesting is the input list. Bluetooth 5.3 is the primary path, with a stated range of about 10 meters, and it can hold a connection to two devices at once — phone and laptop, say. But you also get a 3.5mm aux cable in the box, so at 0% battery you keep listening. On top of that there's FM radio and microSD/TF card playback, which is genuinely unusual at this tier and handy if your teen wants music without tying up a phone.
Buy it if your teen needs one headphone for everything and you want a wired escape hatch. Skip it if they'll wear it six hours a day and you don't want to think about charging — 15 hours per charge and 2.5 hours to refill is the weak spot here.
Amazon Renewed JBL Tune 510BT: Who It's For
The JBL Tune 510BT is a different philosophy entirely. It's an on-ear headphone — the cups rest against the ear instead of surrounding it — which makes it smaller and lighter at 160 grams. For a teenager, that lightness is the point: it disappears on the head in a way bulkier over-ears don't. The trade-off is pressure. On-ear designs can start to ache after a couple of hours, and there's no way to adjust that beyond how the headband sits.
Battery is where this one runs away with it. JBL rates up to 40 hours of wireless playback, recharged in about 2 hours over USB-C, and a 5-minute emergency charge buys roughly 2 more hours. For a teen who forgets to charge anything, that's the single most practical spec on this page. Bluetooth 5.0 handles streaming and can switch between two devices so a call doesn't get missed, and the stated wireless range is 100 meters — far beyond what you'd realistically need indoors, but it means dropouts are unlikely.
Sound is JBL's "Pure Bass" tuning, driven by dynamic drivers with 32-ohm impedance, 103.5 dB sensitivity and a 20 Hz to 20 kHz range. That full reach down to 20 Hz is why bass-heavy tracks hit harder here than on the PowerLocus. Controls are physical buttons on the ear cup, including a multi-function button that summons Siri or Google Assistant. There's no 3.5mm jack, so this is wireless-only.
The renewed angle deserves a straight explanation. These are pre-owned units that were returned or traded in, then inspected and tested by Amazon-qualified suppliers to work and look like new, and sold under the Amazon Renewed program. If something's wrong, the Amazon Renewed Guarantee covers replacement or refund. The manufacturer warranty listed is 90 days limited. That's a shorter safety net than PowerLocus offers, and it's the honest cost of going renewed.
Buy it if your teen streams constantly, wants minimal weight and hates charging. Skip it if they need a wired option, prefer the feel of cushions around the ear, or you want the longest possible warranty.

If I were buying for a teenager, I'd pick the PowerLocus Over-Ear. Here's my reasoning: kids lose chargers, forget to plug things in, and treat headphones roughly. The wired fallback means the headphones never become useless, the over-ear fit is more forgiving for long sessions, and the 24-month warranty is a real cushion. The renewed JBL wins on battery and bass reach, and if your teen is the type who streams nonstop and never wants a cable, it's the smarter buy. But if you're shopping teen headphones for someone who's starting to care about sound — the way people do when they search for the best bluetooth open ear headphones for audiophiles or hunt for earbuds for audiophiles — remind them that at this level, fit and battery matter more than spec sheets. Neither is an audiophile product. Both are good everyday tools. The PowerLocus is the more forgiving one.
Renewed means the unit was returned or traded in, then inspected and tested by Amazon-qualified suppliers to work and look like new, sold under the Amazon Renewed program. You get a 90-day limited warranty and the Amazon Renewed Guarantee for replacement or refund. It's a reasonable path if you want the JBL design without paying new-product money — check the current price on Amazon and compare.
Yes. They include a 3.5mm aux cable, so you can listen wired even at 0% battery. They also support FM radio and microSD/TF card playback, which the JBL does not offer at all.
On the specs, the JBL reaches down to 20 Hz while the PowerLocus bottoms out at 110 Hz, so the JBL's Pure Bass tuning should dig deeper. The PowerLocus counters with 40mm drivers and a bass-forward tuning of its own, but the low-end extension favors JBL.
The PowerLocus pairs with phones, tablets and laptops over Bluetooth, but connecting to a TV or Nintendo Switch requires an additional Bluetooth transmitter. The JBL uses standard Bluetooth 5.0, so it pairs with Bluetooth-enabled devices; a Switch without Bluetooth audio needs a transmitter too.
