If you want compact wireless earbuds with bass, app-based EQ, and long battery life for work from home, choose Anker Soundcore; if you need wired over-ear headphones with a built-in mic and a volume limit for a child, choose EarFun K3. These products are built for different listeners, so the key choice is whether you want personal wireless earbuds or kid-focused headphones for calls, classes, and listening.
• Anker Soundcore P20i: Strongest for wireless convenience, bass-forward listening, and flexible sound settings; its trade-off is that it is an in-ear model, not a child-sized over-ear headset.
• EarFun K3: Strongest for a wired, foldable over-ear design with an 85/94 dBA volume limit and a built-in mic; its trade-off is that it has no wireless connection or noise-control feature.
• Choose Anker Soundcore if you want earbuds for your own music, calls, and everyday portable use.
• Choose EarFun K3 if you want a child-focused headset for schoolwork, travel, or online classes.
• For a shared work-from-home setup, the decision hinges on whether the adult wants wireless earbuds or the child needs wired headphones with a volume limit.
The Soundcore P20i is the more flexible pick for an adult who wants small, wireless earbuds for music, calls, and everyday listening. Its 10 mm drivers are designed to give sound extra bass, while the Soundcore app offers 22 EQ presets and customizable touch controls. There is also a gaming mode in the app, so it can suit someone who switches between music and mobile games.
Battery life is a practical strength on paper: the earbuds are specified for up to 10 hours on a charge, with up to 30 hours when the case is included. A 10-minute charge is listed as providing two hours of playtime. The case is compact and has an attached lanyard, which may be handy if you want to carry it on a bag or keys. Bluetooth 5.3 and a stated 10-meter range support untethered listening, while two microphones and an AI algorithm are intended to help pick up your voice on calls.

I’d choose the P20i for an adult who values portability, wireless listening, and sound customization. I’d skip it if the main buyer is a child who needs an over-ear fit and a defined volume limit. It does list passive noise cancellation, but the supplied information does not establish an active noise-canceling system, so I would not choose it expecting electronic noise cancellation.
The EarFun K3 is not a direct style match for the P20i. It is a wired, over-ear kids’ headphone with a built-in microphone, a 3.5 mm jack, and a foldable design. Its 85/94 dBA volume-limit feature is the clearest reason to consider it for a child. It is also described as suitable for calls and online classes, where the built-in mic can support two-way communication.
That makes the K3 an obvious fit for a child using a compatible tablet or other device with a headphone jack. The wired connection avoids charging the headphones, but it also means the listener is physically tethered to the device. The available specifications list no noise-control feature, so I would not expect it to block surrounding sound electronically. Its foldable construction is useful for packing, though the supplied details do not establish a case or wireless option.
For the work-from-home scenario, the K3 makes more sense as a child’s headset during a lesson or call than as an adult’s all-purpose headphones. A parent searching for crystal clear calls kids headphones for work from home may find the built-in mic and volume limit relevant, but no microphone specification guarantees a particular call quality. I’d pass if you specifically need Bluetooth, earbuds, or headphones with a stated noise-control function.
• Best for wireless listening → Anker Soundcore. The P20i connects over Bluetooth 5.3, while the K3 uses a wired 3.5 mm connection.
• Best for a child’s volume-limited headphones → EarFun K3. It offers an 85/94 dBA volume limit and an over-ear design intended for kids.
• Best for calls or online classes with a child → EarFun K3. It has a built-in microphone and a wired connection suited to a device with a headphone jack.
• Best for adjusting sound to personal taste → Anker Soundcore. Its app includes 22 EQ presets and customizable touch controls.
• Best for avoiding a charging routine → EarFun K3. It is wired, so it does not depend on a headphone battery for listening.
• Best for longer listening away from an outlet → Anker Soundcore. The stated playtime is up to 10 hours on a charge and up to 30 hours with the case.
• Best for someone looking for sleep headphones for work from home → Neither is an obvious match. The P20i sits in the ear, while the K3 is an over-ear wired headset; the supplied details do not establish either as a sleep-specific design.
One point worth keeping straight: “clear calls” is not a feature that makes these two interchangeable. The P20i’s two microphones and AI algorithm are aimed at voice pickup for calls, while the K3’s built-in mic targets children’s calls and online classes. Neither specification gives a guarantee for every room, device, or background-noise situation.
My Verdict
In my opinion, I’d buy the Anker Soundcore P20i for my own everyday use: it combines wireless convenience, app-based EQ, bass-focused drivers, and substantial stated battery life. For work from home, it is the more versatile pick if I want compact earbuds for calls and listening between tasks. I’d choose the EarFun K3 instead when the buyer is a child who needs wired over-ear headphones, a built-in mic, and a volume limit.
Yes. The P20i connects over Bluetooth 5.3. Its listed battery life is up to 10 hours from the earbuds, with up to 30 hours when the charging case is included.
The K3 is an over-ear wired model with a built-in microphone, a 3.5 mm jack, and an 85/94 dBA volume limit. Those features suit a child using a compatible device for lessons, though the device needs a headphone jack or a compatible connection.
They are designed for different call scenarios. The P20i has two microphones and an AI algorithm intended to help pick up the wearer’s voice; the K3 has a built-in mic for calls and online classes.
The P20i lists passive noise cancellation, while the K3 lists no noise-control feature. The supplied information does not show active noise cancellation for either model, so don’t assume either will electronically cancel surrounding noise.
