If you want compact wireless earbuds with bass, long battery life, and app controls, choose Anker Soundcore; if you need wired, kid-focused on-ear headphones with an 85 dB volume limit, choose EarFun S1. For sleeping, neither is a dedicated sleep design: Soundcore’s in-ear shape is the closer fit, while EarFun S1 sits over the ears and connects by cable.
The key difference in this earfun vs anker earbuds comparison is that these are not two versions of the same product. Soundcore P20i is a wireless earbud set for everyday listening and calls. EarFun S1 is a wired children’s headphone set designed for school, travel, and listening at a limited volume.
• Anker Soundcore P20i: Its strengths are up to 10 hours of listening from the earbuds, up to 30 hours with the charging case, and customizable EQ. Its trade-off is that it has no stated active noise cancellation or sleep-specific design.
• EarFun S1: Its strengths are an 85 dB volume limit, foldable on-ear design, and a standard 3.5 mm wired connection. Its trade-off is that it is a children’s headphone, not a wireless earbud.
• Choose Soundcore if you want a compact Bluetooth option for music, calls, and everyday carry.
• Choose EarFun S1 if you are buying for a child and prioritize a volume limit, a wired connection, and foldable storage.
The Soundcore P20i is the more natural choice if you specifically want earbuds. Its in-ear design keeps the listening setup compact, and Bluetooth 5.3 means there is no headphone cable to connect to your phone or tablet. The case is also described as small and lightweight, with a lanyard attached. That makes it easier to keep with everyday essentials than a larger over-ear-style set.
For music, the P20i has 10 mm dynamic drivers and a sound profile that emphasizes bass. The Soundcore app adds 22 EQ presets, so you can adjust the listening profile rather than being limited to one default setting. The app also lets you customize touch controls, and its “Find My Earbuds” function can make a misplaced earbud emit a sound. These features are useful if you want some control over listening and handling without carrying a separate audio player or wired accessory.
Battery life is one of its clearest practical strengths: the earbuds are listed for up to 10 hours on a charge, with up to 30 hours total when the case is included. A 10-minute quick charge is stated to provide two hours of playtime. The P20i also has two microphones and an AI-based call feature intended to pick up your voice, which gives it a more obvious role for calls than the EarFun S1. It supports single-earbud use, too, which can be useful when you want one ear free.

For sleep, the P20i is the closer match of these two because it is an in-ear product rather than an on-ear headphone. But that does not make it a purpose-built sleep earbud. The provided details describe sound isolation, not active noise cancellation, and offer no sleep-specific shape, comfort claim for side sleeping, or noise-masking feature. If your search is for the best noise cancelling wireless earbuds for sleeping, these specs do not establish that the P20i provides active noise cancellation.
Who should skip it: Skip Soundcore if you need a child-focused 85 dB limit, a wired 3.5 mm connection, or confirmed active noise cancellation.
EarFun S1 is a different kind of product altogether. It is a wired, on-ear headphone designed for kids, with an adjustable headband and a stated 85 dB volume limit. That limit makes the product’s intended audience and use especially clear: it is built for children’s listening, including schoolwork, online courses, travel, music, and audiobooks. It does not offer the wireless convenience or pocket-sized earbud form of the P20i.
Its 40 mm drivers are intended to deliver stereo sound for speech, music, and video. The product information describes clear mid and high frequencies alongside bass, though it does not specify an adjustable EQ or a companion app. Instead, the focus is on a straightforward wired setup: the standard 3.5 mm connector can be used with devices that have a matching headphone port. That can be convenient for a compatible tablet or computer, but it is a constraint if the device has no 3.5 mm jack.
The S1 folds and has 90-degree rotating earcups, and the listed weight is 118 g. Those details point to a portable design that can be packed away more easily than a rigid, non-folding headset. Its soft earcaps and adjustable headband are intended to help with fit during listening. Still, these are on-ear headphones, so they sit on the ears rather than inside them. That makes them a poor choice for anyone seeking compact earbuds or something designed for sleeping.
The volume limit is the most distinctive reason to consider the S1. Its intended role is not to compete with a wireless adult earbud set on battery life, app controls, or call features. It is a simple wired option for a child, with sound output limited to the stated level. If you want the best bluetooth earbuds for sleeping, this is not a match: it is wired, on-ear, and designed for children rather than sleep listening.
Who should skip it: Skip EarFun S1 if you need Bluetooth, in-ear earbuds for sleep, or a product for adult everyday calls.
• Best for wireless listening → Anker Soundcore. The P20i connects over Bluetooth 5.3; the EarFun S1 uses a wired 3.5 mm connection.
• Best for a child-focused volume limit → EarFun S1. Its stated 85 dB limit is a key part of its design.
• Best for longer listening between charges → Anker Soundcore. It is listed for up to 10 hours per earbud charge and up to 30 hours with the charging case.
• Best for app-based sound adjustments → Anker Soundcore. Its app offers 22 EQ presets and customizable touch controls.
• Best for school or travel packing → EarFun S1. Its earcups rotate and fold, and its listed weight is 118 g.
• Best for calls → Anker Soundcore. It has two built-in microphones and an AI-based call feature; the EarFun S1 is a wired kids’ headphone without a listed call-focused microphone feature.
• Closer fit for sleep listening → Anker Soundcore. Its in-ear form is more plausible for this use than the S1’s on-ear design, but neither product’s listed features establish that it is made for sleeping.
• Best for a device with a 3.5 mm jack → EarFun S1. Its wired plug suits compatible devices, while the P20i connects wirelessly.
I’d choose the Anker Soundcore P20i for everyday adult listening because it is actually an earbud, offers Bluetooth, and combines a long listed battery life with app EQ and call microphones. It is also the more plausible of these two for sleeping, although I would not call it a dedicated sleep or noise-cancelling model based on the available features. For a child who needs a wired set with an 85 dB limit, I’d choose EarFun S1 instead.
Before deciding, check who will use the headphones and what device they will connect to. The P20i is aimed at wireless listening and needs charging; the S1 relies on a 3.5 mm port. A device without that jack will not fit the S1’s stated connection without a compatible adapter, which is not listed as included.
Think about the physical form, too. Earbuds sit in the ear, while the S1 rests on the ears and has an adjustable headband. If you are comparing options for sleeping, that difference matters more than a feature checklist: neither product is described as having a sleep-specific design, and the provided Soundcore details do not claim active noise cancellation. The S1’s 85 dB limit is relevant for its kid-focused use, but it does not turn it into a sleep headphone.
Finally, distinguish convenience from intended purpose. Soundcore has the edge for carrying a small wireless case, customizing sound, and taking calls. EarFun S1 is the more straightforward choice for a child using a compatible device, with foldable storage and a stated volume cap. If product cost is part of your decision, check the current price on Amazon rather than relying on an old figure; the right choice still comes down to fit, connection type, and who will use it.
The P20i is the closer fit because it is an in-ear wireless earbud; the S1 is an on-ear children’s headphone with a cable. Neither product is described as sleep-specific, and the P20i’s listed sound isolation does not establish active noise cancellation.
No. EarFun S1 is a wired headphone with a 3.5 mm connection. It is suitable for devices with a matching headphone jack.
The P20i is the only one of the two with a stated battery life: up to 10 hours from the earbuds and up to 30 hours with the case. The EarFun S1 is wired, so it does not use a rechargeable battery for wireless playback.
No. It is a children’s on-ear headphone with a headband. The Anker Soundcore P20i is the in-ear earbud option in this comparison.
