If you want a complete, kid-safe wireless headphone that also works over a 3.5mm aux cable, choose PowerLocus Headphones; if you need a replacement aux cord to run wired audio into a set of Sony wireless headphones you already own, choose Asobilor 4.9FT.
• PowerLocus Headphones — biggest strength: a full headphone, not an accessory. Bluetooth 5.3, a 3.5mm aux mode, FM radio, Micro SD playback, a mic, and a hard 85dB volume ceiling for kids.
• PowerLocus Headphones — biggest trade-off: the 85dB cap and kid-focused tuning mean it isn't built for adults chasing loud, critical listening, and TV/console wireless use may need a separate Bluetooth transmitter.
• Asobilor 4.9FT — biggest strength: a purpose-built 4.9FT aux cable with high-purity copper and gold-plated male-to-male 3.5mm connectors, sized for Sony WH-series headphones.
• Asobilor 4.9FT — biggest trade-off: it makes no sound on its own. It's a cable, so it only helps if you already own compatible headphones.
• Who each pick is for: PowerLocus for parents buying a first real headphone for a child; Asobilor for Sony WH-1000X / WH-CH / WH-XB owners who lost or wore out the stock aux cord.
The PowerLocus P2 is a kids' over-ear headphone that happens to be unusually flexible about how it plays. It runs Bluetooth 5.3 with roughly 33ft / 10m of wireless range, and it also accepts a 3.5mm aux cable, an FM radio signal, and a Micro SD card. That last part matters more than it sounds: a child can keep using it on a long car ride or a flight even when the battery is flat, because wired mode has no runtime limit. Wireless playtime is quoted at 15 hours, with a 2-hour charge time via the included USB cable.
Safety is the headline feature. Volume is capped at 85dB, which the brand describes as a widely used safe listening standard for children. For parents, that's the whole pitch — clear stereo sound with some bass presence, but no way for a kid to crank it into hearing-damage territory. The 40mm dynamic drivers and 32-ohm impedance make it easy to drive from a phone, tablet, or laptop, and the soft protein-foam ear cushions plus padded headband are sized for smaller heads. It folds flat, ships with a hard-shell carry case, and weighs 165g, so it disappears into a backpack.
Who should buy it: a parent who wants one headphone that covers school, travel, and tablet time, and who values the volume limit over raw loudness. Who should skip it: adults who want an audiophile-grade or noise-cancelling headphone, anyone who needs low-latency wireless with a TV or console out of the box, and anyone who finds an 85dB ceiling too quiet for their taste.
The Asobilor 4.9FT is a single-purpose product, and it's honest about that. It's a 4.9FT (1.5m) grey aux cable with 3.5mm male-to-male connectors, designed as a replacement cord for Sony WH-1000XM6, XM5, XM4, XM3, WH-CH510, CH710N, CH700N, and WH-XB910N wireless headphones. If you own one of those and you've lost the original cable — or the original got chewed up in a bag — this is the direct fix.
The build is where the value sits. High-purity copper conductor with gold-plated connectors is aimed at stable, low-loss signal transfer, which is what you want when the whole point of the cable is to bypass Bluetooth and feed analog audio straight into the headphone. The PVC jacket plus strain relief at the ends is the part that usually fails on cheap cords; Asobilor explicitly designs against bending fatigue, and PVC's heat resistance helps if the cable lives in a hot car or a cramped laptop bag. The 1.5m length is the sweet spot for desk and couch use — long enough to reach a laptop or a controller, short enough that it isn't a tangled mess.
Who should buy it: Sony WH-series owners who need a spare or replacement aux cord, plus anyone who wants a clean analog connection for wired listening, gaming, or flights where Bluetooth is banned or unreliable. Who should skip it: anyone who doesn't own compatible headphones, and anyone expecting it to add features — there's no inline mic or remote on this cable, so it's audio transmission only.
Side-by-Side: Which Should You Choose?
• Best for a child's first headphone → PowerLocus Headphones. The 85dB limit is the reason to buy it.
• Best for battery life and untethered use → PowerLocus Headphones. 15 hours wireless, plus unlimited wired playback.
• Best for plug-and-play with no charging at all → Asobilor 4.9FT. A cable never needs a battery.
• Best for multiple listening sources → PowerLocus Headphones. Bluetooth, aux, FM radio, and Micro SD give a kid four ways to listen.
• Best for travel and storage → PowerLocus Headphones. It folds flat and comes with a hard-shell case.
• Best for a small, cheap fix to a lost accessory → Asobilor 4.9FT. One job, done with copper and gold plating.
• Best for durability under daily flexing → Asobilor 4.9FT. PVC jacket and strain relief are built for repeated bending.
In my opinion, these two aren't really competitors — they solve different problems, and the right answer depends on what's already in your bag. If you're buying a headphone for a kid, I'd take the PowerLocus Headphones: the 85dB limit, the foldable over-ear design, the carry case, and the four listening modes make it the more useful purchase for a family. If you already own a Sony WH-series headphone and just need the wire back, I'd take the Asobilor 4.9FT — a copper-and-gold-plated cable with strain relief is exactly what a replacement aux cord should be. Check the current price on Amazon before you commit, since that's the one thing that could tip an otherwise close call.
how to make aux cable with headphones
You don't need to make one — you connect an existing cable. A headphone with a 3.5mm jack, like the PowerLocus P2 in aux mode, takes a standard male-to-male 3.5mm cord such as the Asobilor 4.9FT and plugs straight into a phone, tablet, laptop, or MP3 player. Just make sure both ends are 3.5mm and the headphone is switched to wired mode.
how to use wired headphones without headphone jack
Use an adapter. Many phones and tablets have dropped the 3.5mm socket, so you'd pair a 3.5mm-to-USB-C or 3.5mm-to-Lightning adapter with your cable. The Asobilor 4.9FT ends in a standard 3.5mm male plug on both sides, so it works with whatever adapter your device needs.
Plug the cable into the headphone, then into the phone's 3.5mm port — or into an adapter if the phone has no jack. On the PowerLocus P2, switch off Bluetooth so the headphone reads the analog signal. Volume is then controlled from the phone and the headphone's own volume control.
Does the Asobilor 4.9FT work with non-Sony headphones?
It uses standard 3.5mm male-to-male connectors, so it fits any device with a 3.5mm aux port. Asobilor lists it specifically for Sony WH-1000XM6/XM5/XM4/XM3, WH-CH510/CH710N/CH700N, and WH-XB910N, so fit and finish are tuned for those models.
