If you want more playtime per charge, choose Anker Soundcore; if you need a compact, lightweight fit for small ears, choose TOZO A1. For big ears, neither model is specifically designed around a larger ear shape, so fit should be your first consideration; these are in-ear earbuds, not over-ear headphones.
• Anker Soundcore P20i: Its 10mm drivers, app-based sound options, and up to 10 hours of listening per charge are its biggest strengths. Its main trade-off is that its case-inclusive playtime is up to 30 hours, below TOZO’s stated 32 hours.
• TOZO A1: Its lightweight design is specifically described as suited to small ears, and its case provides up to 32 hours of total playtime. The trade-off is a shorter stated single-charge limit of up to 7 hours.
• Choose Anker Soundcore if longer sessions between case recharges, bass-focused sound options, or a compact case with a lanyard matter most.
• Choose TOZO A1 if low weight, a small-ear fit, water resistance, or more EQ presets matter most.
• Both use Bluetooth 5.3, have two microphones for calls, and let you adjust sound through a companion app.
The Soundcore P20i is the more appealing pick if your listening routine includes long stretches away from a charging case. It offers up to 10 hours on a single charge and up to 30 hours with the case, giving it a longer stated earbud-only run than the TOZO A1. A 10-minute charge is also specified to provide up to two hours of playtime, a useful detail if you realize the earbuds are low before heading out.
Sound is another reason to consider the P20i. Its 10mm dynamic drivers are described as delivering powerful sound with boosted bass, while the Soundcore app offers 22 EQ presets and customizable touch controls. There is also a gaming mode accessed through the app, plus a Find My Earbuds feature that can make a misplaced earbud emit a sound. Those features give you more ways to tailor everyday listening and handle small practical annoyances.
The charging case is described as compact and lightweight, with an attached lanyard that can be clipped to a bag or keys. Two built-in microphones work with an AI algorithm for calls. The earbuds also use Bluetooth 5.3 and sound isolation, rather than a stated active-noise-cancellation feature. That distinction matters: I would not choose these expecting a transparency mode or a specified noise-cancelling system.

Who should skip it: Skip the P20i if you want the smallest-ear-focused design described here, or if your priority is a stated IPX5 water-resistance rating.
The TOZO A1’s clearest fit advantage is its small, lightweight in-ear design. Each earbud is listed at 3.7 grams, and the product is described as being made for small ears with a low-profile shape. That may make it a more natural starting point for someone who finds many earbuds bulky. Still, the supplied details do not establish a special fit for big ears; a small-ear design is not automatically a better match for a larger ear.
TOZO specifies up to seven hours of playtime from the earbuds and up to 32 hours total with the charging case. The single-charge figure is shorter than Anker’s, but the stated total with the case is slightly higher. Bluetooth 5.3 supports wireless listening, while the TOZO app provides 32 EQ presets. The sound description emphasizes clear vocals, balanced mids, and bass, giving the A1 a more balanced stated profile than the P20i’s explicit emphasis on boosted bass.
For calls, the A1 has two microphones and ENC described as helping reduce background noise such as traffic and office sounds. It also has an IPX5 waterproof rating. These are practical features for everyday calls and situations where water resistance is relevant, though they do not establish that the earbuds are suitable for every activity or exposure. The case includes LED colors that indicate battery status.
Who should skip it: Skip the A1 if you want the longer stated listening time on a single charge or a quick-charge claim like the P20i’s.
• Longer listening between case visits → Anker Soundcore. Its stated single-charge playtime is up to 10 hours, compared with up to seven for TOZO.
• More stated total time with the case → TOZO A1. TOZO specifies up to 32 hours in total, while Anker specifies up to 30 hours.
• Bass-forward sound options → Anker Soundcore. Its 10mm drivers are described as producing boosted bass, and the app includes 22 EQ presets.
• More EQ presets → TOZO A1. It offers 32 presets through its app, compared with Anker’s 22.
• Small-ear-focused design → TOZO A1. Its lightweight, low-profile shape is specifically described as designed for small ears.
• A quick top-up before leaving → Anker Soundcore. Its stated 10-minute charging benefit is up to two hours of playtime.
• A stated water-resistance rating → TOZO A1. It carries an IPX5 rating; the Anker details provided do not list an equivalent rating.
• A lanyard on the case → Anker Soundcore. Its compact case includes one, which can be clipped to a bag or keys.
Buying Considerations
The phrase best headband headphones for big ears also points to a different kind of product than either model here. Neither is a headband headphone, and neither has a headband that surrounds the ears. Likewise, shoppers looking for transparency mode neckband headphones for big ears should note that these are true wireless earbuds, not neckband headphones, and the listed features do not specify a transparency mode.
For battery planning, compare both figures rather than looking only at the case-inclusive total. Anker’s advantage is the stated time per charge, which may suit a long commute or extended listening without reaching for the case. TOZO’s advantage is its slightly higher stated total with the case. These are manufacturer-provided playtime figures, not a guarantee of identical results for every listening pattern.
Calls and sound customization also point in different directions. Both have two microphones and app-based sound options. TOZO describes ENC for reducing certain background sounds during calls, while Anker describes an AI algorithm for voice pickup. The provided details do not give a direct measured comparison of call performance, so I would treat those as feature differences rather than proof that one will sound clearer in every environment.
Finally, consider the handling details you will actually use. The P20i offers a case lanyard, customizable touch controls, and Find My Earbuds. The A1 provides an LED battery-status indication on its case and an IPX5 rating. These features solve different everyday problems; the better match depends on whether you care more about keeping track of the case, checking its battery status, or having a stated water-resistance rating.
I would choose the Anker Soundcore P20i for its longer stated playtime per charge, quick-charge feature, and bass-focused sound options. For big ears, though, I would not assume either model will fit well based on the specifications alone; both are in-ear earbuds, and TOZO is specifically oriented toward small ears. If low weight and IPX5 water resistance matter more, I would choose the TOZO A1 instead.
Anker specifies up to 10 hours on a single charge and up to 30 hours with its case. TOZO specifies up to seven hours per charge and up to 32 hours with its case, so the winner changes depending on which figure matters to you.
The A1 is described as a lightweight design made for small ears. That does not establish how it will fit a person with big ears, so the listed information cannot guarantee a comfortable fit for that use.
The supplied details do not list a transparency mode for either product. They identify both as true wireless in-ear earbuds; Anker lists sound isolation, while TOZO lists ENC microphones for calls.
Both have two microphones and describe AI-related call features. Anker emphasizes voice pickup, while TOZO describes ENC as reducing background sounds such as traffic and office noise; the listed specifications do not provide a direct performance comparison.
