• PowerLocus Headphones — biggest strength: A full over-ear headset with Bluetooth 5.3, a 3.5mm aux jack, FM radio and Micro SD playback, a hard 85dB volume cap for kids, and up to 15 hours of wireless playtime.
• PowerLocus Headphones — biggest trade-off: It's a single pair of headphones built around children, so it's less useful if you're an adult trying to revive a wired set you already own.
• YGKSAA 4PCS — biggest strength: Four USB-C-to-3.5mm adapters with a built-in DAC chip, plug-and-play, so any old wired headphones work on USB-C phones, tablets and laptops.
• YGKSAA 4PCS — biggest trade-off: It's a passive adapter, not audio gear — no headphone jack on your device means it's useless, and Apple headphone mic/volume controls aren't supported.
• Who each pick is for: PowerLocus for parents buying a safe first headset; YGKSAA for anyone with a drawer of wired headphones and a jackless device.
The PowerLocus over-ear headset is a self-contained listening device. It runs Bluetooth 5.3 with a rated range around 12 meters (roughly 33 feet), and it also accepts a 3.5mm aux cable, so wired mode is always there as a fallback when the battery runs down. Inside are 40mm dynamic drivers with 32-ohm impedance, and the whole thing weighs just 165g. The included hard-shell carry case weighs 90g, and the frame folds, so it slides into a backpack or suitcase without a fight.
For parents, the headline spec is the 85dB maximum volume limit. That's the feature that makes this a kids' headphone rather than a general-purpose one. The ear cups are over-ear with protein foam and faux leather, so they surround the ear rather than press on it, which helps with passive sound isolation on a bus or a plane. The headband is padded too. This is the kind of headset a child can wear for a long car ride or a flight without constant adjusting.
Who should buy it: a parent or gift-giver who wants one box that covers safe volume, wireless freedom, a wired backup, and offline playback. Who should skip it: an adult who wants neutral, full-volume audio for critical listening, or anyone who just needs to adapt existing wired headphones — the volume ceiling is a deliberate child-safety feature and would be a limitation for grown-up use.
YGKSAA 4PCS: Who It's For
The YGKSAA 4PCS is not a headphone at all. It's a four-pack of USB-C-to-3.5mm-female adapters, each with a single USB-C port on one end and a 3.5mm jack on the other. The job is simple: your device has USB-C and no headphone jack, your headphones have a 3.5mm plug, and this little dongle bridges the two.
The spec that matters most is the built-in DAC chip. Digital audio coming out of a USB-C port has to be converted to an analog signal the headphones can actually use, and that conversion is what the DAC does. YGKSAA describes it as a high-resolution chip that shields current interference and cuts music noise. A compact 3.5mm socket is designed to grip the plug firmly rather than wiggle loose in a pocket. It's plug-and-play — no drivers, no software, no setup. Plug the 3.5mm jack in first, then the USB-C end, and adjust volume on the device the first time you use it.
Compatibility is broad but has real limits, and you should read them before buying. YGKSAA lists Samsung S20/S20+/S20 Ultra, Pixel 4/4/4XL, iPhone, iPad, MacBook, Google Pixel and other USB-C devices. Two caveats are spelled out clearly: phones that already have a 3.5mm headphone jack are not supported (there's nothing for the adapter to add), and Apple headphone microphone and in-line volume controls don't work through it. Devices with recording functions — microphones and sound cards — need a level-4 interface, and a three-level plug is playback-only. The set also covers 12 months of warranty support.
Who should buy it: anyone with a USB-C phone, tablet or laptop and a favorite pair of wired headphones, earbuds or an aux cable for a car stereo. Four adapters means one for the bag, one for the desk, one for the car, one as backup. Who should skip it: anyone whose device still has a real headphone jack, or anyone expecting Apple's mic and remote buttons to work.
• Best for safe listening with kids → PowerLocus Headphones. The 85dB cap is the whole point.
• Best for reviving existing wired headphones → YGKSAA 4PCS. It converts USB-C devices into 3.5mm-ready ones.
• Best for battery life and wireless freedom → PowerLocus Headphones. Up to 15 hours wireless, about 2 hours to charge, and wired mode with no limit at all.
• Best for plug-and-play simplicity → YGKSAA 4PCS. No pairing, no charging, no drivers.
• Best for travel with a child → PowerLocus Headphones. Foldable frame, padded over-ear cups, and a hard-shell case in the box.
• Best for multiple devices or households → YGKSAA 4PCS. The four-count pack spreads across phones, tablets and laptops.
• Best for console or TV audio → PowerLocus Headphones. Bluetooth with PS4/PS5/Xbox/Switch support, though you may need a separate Bluetooth transmitter for some of them.
• Best for an adult who wants loud, uncolored sound → neither, honestly. PowerLocus caps volume for safety, and YGKSAA adds no sound of its own.
In my opinion, the right pick depends entirely on which problem you actually have. If you're buying for a child, I'd go with PowerLocus Headphones — the 85dB limit, the foldable build, the 165g weight and the four listening modes make it a genuinely complete gift, and the aux jack means it still works when the battery is flat. If you're an adult with a USB-C phone and a beloved pair of wired headphones, the YGKSAA 4PCS is the smarter buy: it costs little, needs no setup, and four adapters mean you'll never be caught without one. I wouldn't buy YGKSAA expecting headphones, and I wouldn't buy PowerLocus expecting adult-grade volume. Match the tool to the job and you'll be happy either way.

how to use wired headphones without headphone jack
You need an adapter that converts your device's USB-C port into a 3.5mm jack — exactly what the YGKSAA 4PCS does with its built-in DAC chip. Plug the 3.5mm end of your headphones in first, then the USB-C end into the phone or tablet, and adjust the volume on the device the first time. No drivers or software are required.
how do i connect my wired headphones to my phone
If your phone still has a 3.5mm jack, just plug straight in — the YGKSAA adapter isn't supported on those. If your phone is USB-C only, use the YGKSAA dongle: 3.5mm jack in, USB-C plug in, play. Note that Apple headphone microphone and in-line volume controls won't work through this adapter.
how to make aux cable with headphones
You don't need to build anything — a 3.5mm aux cable fits the 3.5mm jack on the YGKSAA adapter and the aux input on a car stereo or speaker. PowerLocus Headphones also run in wired aux mode, so a standard 3.5mm cable works with them directly. Three-level plugs are playback-only; recording devices need a level-4 interface.
what's the difference between these two for kids
PowerLocus is a complete over-ear kids' headset with an 85dB volume limit, Bluetooth 5.3, aux, FM and Micro SD playback, and up to 15 hours of wireless use. YGKSAA is only an adapter, so it adds no volume protection and no sound of its own. For a child, the PowerLocus is the safer pick.
