If you want compact in-ear earbuds with customizable bass and a pocketable charging case, choose Anker Soundcore; if you need volume-limited, over-ear headphones for a child’s commute, choose EarFun K2. For commuting, the key difference is who’s wearing them: Soundcore suits an adult who wants portable personal audio, while EarFun is built around children’s listening and a more covering fit.
• Anker Soundcore P20i: Its standout is compact in-ear portability, with up to 10 hours of listening per charge and up to 30 hours with the case. The trade-off: it has no stated volume limit or wired listening option.
• EarFun K2: Its standout is a kid-focused over-ear design with volume limiting and up to 40 hours of battery life. The trade-off: it is a larger headphone rather than a small earbud that slips into a pocket.
• Choose Soundcore if you want lightweight earbuds, adjustable EQ, and a charging case for everyday travel.
• Choose EarFun if you’re choosing headphones for a child and prioritize volume limits, a foldable frame, and the option to connect with a cable.
The Soundcore P20i is a true wireless in-ear option for someone who wants a small listening setup for a commute, a walk, or a break between errands. Its 10 mm drivers are designed to deliver boosted bass, and the Soundcore app offers 22 EQ presets for adjusting the sound. You can also customize touch controls in the app, so there is some flexibility in how you manage playback.
Battery life is a practical strength. The earbuds are specified for up to 10 hours on a charge, with the case extending total listening time to 30 hours. A 10-minute charge is stated to provide two hours of playback. The case is compact and has an attached lanyard, giving you the choice of slipping it into a pocket or clipping it to a bag or keys. Bluetooth 5.3, two built-in microphones with an AI-based call feature, and a Find My Earbuds function round out the everyday-use package.

I’d consider the P20i if you want the compact form factor of earbuds and value bass adjustment, call features, and a case that adds listening time. I’d skip it for a child if your priority is a stated volume limit: the provided product information does not list one. It also has passive noise cancellation, not an advertised active noise-cancelling system, so it is not the pick here for someone specifically seeking active noise cancellation.
The EarFun K2 is not a small in-ear earbud. It is a foldable, over-ear Bluetooth headphone made for kids and teens, with soft memory-foam cushioning and an adjustable headband. The product information describes volume limiting at 85 or 94 dB. That gives parents a specific listening-safety feature to consider, though the listed information does not describe active noise cancellation.
For a child’s commute, the over-ear shape may be more suitable than tiny earbuds that can be misplaced, and the foldable design is intended to make packing easier. The K2 is rated for up to 40 hours of playback, with a stated recharge time of 2.5 hours. It also has a built-in microphone for calls or online learning, Bluetooth 5.4, and a 3.5 mm connection. That cable is useful when a wired connection is preferred or the battery has run down.
I’d look at the K2 for a family choosing a kids headset for commuting, school travel, or tablet use, especially when the volume limit and wired option matter. It is not the right match if you want discreet earbuds or a small case to carry in a pocket. Its over-ear design takes a different approach to portability: it folds, but it is still a headband-style headphone.
• Best for a compact commute kit → Anker Soundcore. The P20i earbuds and case are described as compact and lightweight, and the case has a lanyard for carrying on a bag or keys.
• Best for a child’s listening setup → EarFun K2. It is specifically designed for kids and teens, with an over-ear fit and a stated 85/94 dB volume limit.
• Best for longer listed battery life → EarFun K2. It is specified for up to 40 hours of playback. The P20i offers up to 10 hours per charge and up to 30 hours with its case.
• Best for customizable sound → Anker Soundcore. Its app provides 22 EQ presets, including bass-focused tuning, and allows touch-control customization.
• Best if you may need to listen by cable → EarFun K2. It includes a 3.5 mm connection and audio cable; the P20i is listed as wireless with no headphone jack.
• Best for a quick battery top-up → Anker Soundcore. Its stated 10-minute charging boost provides two hours of playback. The K2’s listed battery recharge time is 2.5 hours.
• Best for calls during study or travel → Either, for different users. The P20i has two built-in microphones and an AI call feature; the K2 has a built-in microphone intended for hands-free calls, including online learning.
• Best lightweight earphones for commuting → Anker Soundcore, if you want earbuds. The K2 is foldable and described as lightweight, but it remains an over-ear headphone rather than an in-ear option.
The distinction matters more than any single spec. Soundcore is the adult-oriented portable earbud choice in this comparison. EarFun is the child-focused headphone choice, with design details and controls aimed at a different listener.
My Verdict
For an adult who wants small in-ear earbuds and a compact case, the P20i is the closer fit. For a child, the K2 offers an over-ear design, a stated volume limit, and a cable option.
EarFun lists up to 40 hours of playback. Soundcore lists up to 10 hours on a charge and up to 30 hours with the charging case, plus a quick-charge feature that provides two hours of playback after 10 minutes.
The listed noise-control specification says none. It should not be treated as a noise-cancelling headphone based on the available product details.
The K2 is the more directly child-focused choice: it is designed for kids and teens and has a stated 85/94 dB volume limit. The P20i is an in-ear model whose listed features do not include a volume limit.
