If you want to turn a wired car stereo, home speaker or old pair of aux headphones into a Bluetooth device — and you care most about long battery life for video calls and music — choose Golvery V5.4; if you need actual headphones on a kid's head, with a microphone for video calls and online classes, choose QearFun Kids Unicorn. Those are two very different jobs, even though both show up when people search for aux wired headphones. One is a tiny adapter that adds wireless freedom to gear you already own. The other is a complete kids headset for video calls, school and travel. Let me break down which one actually fits your situation.
• Golvery V5.4 — biggest strength: Bluetooth 5.4 receiver with 3.5mm AUX and RCA output, 20 hours of playtime, and it keeps streaming while charging.
• Golvery V5.4 — biggest trade-off: It is not a headset. It is a 13 g adapter, so you still need your own wired headphones, speaker or stereo to hear anything.
• QearFun Kids Unicorn — biggest strength: A complete over-ear kids headset with a built-in HD mic, 60-hour battery, 3-level volume limit (74/85/94dB) and wired mode as a backup.
• QearFun Kids Unicorn — biggest trade-off: It is built for kids (ages 3–20 per the manufacturer), so it is not the tool for upgrading an adult hi-fi or car stereo.
• Who each pick is for: Golvery V5.4 → anyone modernizing a wired speaker, car aux input or wired headphones. QearFun Kids Unicorn → parents who want a safe, mic-equipped headset for a child.
The Golvery V5.4 is a Bluetooth receiver, not headphones. That single fact decides everything. You plug its 3.5mm AUX or RCA output into something that already makes sound — a car stereo aux input, a home speaker, a wired headphone — and it receives audio wirelessly from your phone. The upgraded Bluetooth 5.4 chipset with the A2DP profile is there for stable connectivity and clear Hi-Fi streaming, which is exactly what you want when the adapter is buried in a glovebox or sitting behind a speaker.
The feature I'd actually lean on is the 20-hour battery. A 240mAh lithium battery, a 2-hour USB-C charge, and roughly 20 hours of playback is a genuinely useful ratio for a device this small. Better still, it can keep working while it charges, so a long video call or an all-day road trip doesn't have to end because the adapter died. It also reconnects to the last paired device automatically when that device's Bluetooth is on, and it can hold a dual connection to two phones — handy if you and a partner share one car stereo. Controls are touch-based buttons, and the whole thing weighs 13 g with a plastic enclosure, so it disappears in a pocket.
Who should buy it: someone with good wired audio gear and no Bluetooth. A car with only an aux jack. A bookshelf speaker. A pair of wired headphones you love but want to untether. Anyone who wants the best waterproof neckband headphones for video calls should look elsewhere — this isn't a neckband, and it isn't waterproof. Who should skip it: anyone who needs a microphone, a headset, or volume limiting for a child. Golvery V5.4 has no mic and no kid safety features. It is a receiver, pure and simple.
The QearFun Kids Unicorn is the opposite kind of product: a finished, wearable headset aimed squarely at children. It's an over-ear design in a Unicorn Pink finish with 40mm dynamic drivers, a 20Hz–20KHz frequency range and 32 ohm impedance — modest, sensible specs for a kid's headphone rather than an audiophile one. The point here isn't reference-grade sound. The point is a safe, comfortable, hard-to-break headset that a child will actually keep on their head.
The headline feature is the 3-level volume limit with a hidden parental button: 74dB for toddlers, 85dB for everyday listening, and 94dB for noisy places like airplanes. If you've ever watched a kid quietly max out the volume on a normal headset, you understand why that hidden control matters. Comfort is handled with soft breathable PU ear cushions and a steel-reinforced adjustable headband sized for ages 3–20. The build is ABS, leather and plastic, and the manufacturer describes it as ready for drops and twists. There's also a 1-year manufacturer warranty.
For school and calls, the built-in HD microphone is the key spec — it's what makes this a kids headset for video calls rather than just a music toy. Bluetooth 5.3 gives a stable connection to iPads, tablets and Chromebooks within about 10 meters, and the 60-hour battery with a 1.5-hour charge time means it survives a school week without drama. Passive noise cancellation helps a little in a busy classroom. And the 3.5mm jack matters more than people think: in wired mode it works with anything, including a laptop or a handheld console with no Bluetooth at all. The foldable design and gift packaging make it an easy present.
Who should buy it: parents of kids roughly 3 to 20 who need a headset for online classes, family calls, tablets and travel. Who should skip it: adults who want serious sound quality, and anyone trying to add Bluetooth to a stereo — this is not that product.
Side-by-Side: Which Should You Choose?
• Best for a child's hearing safety → QearFun Kids Unicorn. A parent-controlled 74/85/94dB limit with a hidden button is something Golvery simply doesn't offer.
• Best for video calls with a microphone → QearFun Kids Unicorn. Built-in HD mic; the Golvery adapter has no mic at all.
• Best for upgrading a car or home stereo → Golvery V5.4. 3.5mm AUX and RCA output, dual phone connection, Bluetooth 5.4.
• Best for long trips and travel → QearFun Kids Unicorn. Foldable, 60-hour battery, over-ear comfort for kids.
• Best open ear headphones for video calls → neither, honestly. These are an over-ear kids headset and a plug-in receiver; if open-ear is a hard requirement, keep looking.
• Best for people who already own great wired headphones → Golvery V5.4. It makes them wireless without replacing them.
• Best for a school bag → QearFun Kids Unicorn. Wired mode is the safety net when Bluetooth isn't allowed or the battery is low.
In my opinion, most people searching this comparison should buy the QearFun Kids Unicorn — because if you're shopping "kids unicorn headphones," you almost certainly need an actual headset for a child, with a mic for video calls, a volume limit, and a wired fallback. I'd only pick Golvery V5.4 if your real goal is to add Bluetooth to a wired speaker, car stereo or pair of aux headphones. Decide which problem you actually have, and the choice is easy.
how to make aux cable with headphones
You don't need to build anything. If you have wired headphones with a 3.5mm plug, plug them straight into your phone, laptop or tablet's aux jack — or into a Bluetooth receiver like the Golvery V5.4 to make them wireless. The QearFun Kids Unicorn also has a 3.5mm jack, so it works the same way in wired mode.
how to use wired headphones without headphone jack
Many phones have dropped the headphone jack, but the QearFun Kids Unicorn and most wired headphones still connect via their 3.5mm plug to a laptop, tablet or console that has a jack. For a phone with no jack, a Bluetooth receiver such as the Golvery V5.4 lets you stream wirelessly to your wired headphones instead.
how do i connect my wired headphones to my phone
Plug the 3.5mm plug into the phone's aux port if it has one. If it doesn't, pair the Golvery V5.4 with your phone over Bluetooth, then plug your wired headphones into the adapter's 3.5mm output. The QearFun Kids Unicorn connects wirelessly over Bluetooth 5.3 and can also run in wired mode.
Yes — it offers a 94dB setting specifically for loud environments, alongside the gentler 74dB and 85dB levels. The parent-controlled hidden button keeps kids from changing it. For everyday listening, 85dB is the sensible middle setting.
The QearFun Kids Unicorn, clearly. It's a complete over-ear headset with a mic, volume limiting, 60-hour battery and wired mode. The Golvery V5.4 has no microphone and no headband — it's an adapter, not something a child wears. Check the current price on Amazon before deciding.
