If you want compact, in-ear earbuds with bass-forward sound and app controls, choose Anker Soundcore; if you need an open-ear clip-on design for big ears and want to stay aware of nearby sounds, choose TOZO OpenEarRing Open Ear.
Anker Soundcore vs TOZO OpenEarRing Open Ear at a Glance
• Anker Soundcore P20i: In-ear fit, 10 mm drivers, 22 EQ presets, and up to 30 hours of playback with the case; trade-off: the in-ear design is not open-ear.
• TOZO OpenEarRing Open Ear: Clip-on open-ear fit, 32 EQ modes, and up to 40 hours with the case; trade-off: its open design does not provide sound isolation.
• Choose Soundcore if you want a small case, customizable touch controls, and a conventional earbud fit.
• Choose TOZO if you prefer not to plug your ears and want to keep more awareness of your surroundings.
Soundcore P20i is the conventional choice in this comparison: each earbud sits in the ear, and its 10 mm dynamic drivers are designed to deliver bass-forward sound. The Soundcore app adds 22 EQ presets, including options for adjusting the listening character, plus customizable touch controls. There is also a gaming mode in the app and a “Find My Earbuds” feature that can make a misplaced earbud emit a sound.
The battery figures make it a practical option for days when you do not want to charge after every short listening session. Anker lists up to 10 hours from the earbuds and up to 30 hours total with the case. A 10-minute quick charge is stated to provide two hours of playback. The case is compact and has an attached lanyard, which gives you another way to carry it besides slipping it into a pocket.

TOZO OpenEarRing takes a different approach. Its clip-on design sits around the ear rather than sealing into the ear canal, leaving you more aware of sounds around you. That can make sense for a walk, a workout, or listening while doing tasks at home or at work. TOZO also describes the design as suitable for glasses wearers, and lists each earbud’s weight as 5.1 grams.
Its feature set includes 32 EQ modes through the TOZO app, touch controls, Bluetooth 5.4, and a stated connection range of up to 15 meters. The earbuds are listed for up to 10 hours of playback on a charge, with up to 40 hours total when the case is included. The charging case has a digital display, and charging uses Type-C.
The main trade-off is inherent to the open-ear format: it does not isolate outside noise. That may be welcome if you want to remain aware of traffic or nearby conversation, but it is less suited to someone seeking a sealed listening experience. If your priority is blocking out surroundings, or if you want a conventional in-ear shape, Soundcore is the clearer fit.
• Best for an open-ear fit → TOZO OpenEarRing. Its clip-on design leaves the ear canal unsealed, while Soundcore P20i sits in the ear.
• Best for bass-forward listening → Anker Soundcore. Its 10 mm drivers are specifically described as delivering boosted bass.
• Best for staying aware of nearby sounds → TOZO OpenEarRing. The open-ear design lets ambient sound remain part of your listening environment.
• Best for sound isolation → Anker Soundcore. Its listed noise control is sound isolation; TOZO lists no noise control.
• Best for the most EQ choices → TOZO OpenEarRing. It offers 32 EQ modes in the app, compared with Soundcore’s 22 presets.
• Best for stated total battery life → TOZO OpenEarRing. Its case-and-earbud total is up to 40 hours, versus up to 30 hours for Soundcore.
• Best for a quick battery top-up → Anker Soundcore. Its stated 10-minute charge provides two hours of playback.
• Best for a compact case with an attached carry option → Anker Soundcore. Its case is described as compact and includes a lanyard; TOZO’s case instead adds a digital display.
For big ears, the choice is not simply which earbud is smaller. It is whether you prefer an earbud inside the ear or a clip-on shape around it. TOZO’s open-ear construction may appeal if in-ear pressure is what you want to avoid, but fit is personal; the stated design alone cannot guarantee comfort for every ear.
My Verdict
I’d choose TOZO OpenEarRing if I were buying specifically for big ears and wanted an open-ear fit that avoids plugging the ear canal. Its clip-on design, glasses-wearer focus, and longer stated total playback make that the more convincing match for that need.
I’d choose Soundcore P20i instead for bass-forward in-ear listening, a compact lanyard case, and a quick-charge option. My pick for the stated big-ear use case is TOZO, with the caveat that open-ear listening does not isolate outside noise.
TOZO OpenEarRing is the more natural fit to consider if you want an open-ear clip-on design rather than an earbud inside the canal. Soundcore P20i is in-ear, so the better choice depends on which style feels more suitable to you.
Neither product lists a transparency mode. TOZO’s open-ear design leaves you more aware of surrounding sounds by design; Soundcore lists sound isolation as its noise-control type.
Which has longer battery life, TOZO or Anker Soundcore?
TOZO says its clip-on earbuds are designed with glasses wearers in mind and weigh 5.1 grams each. That design may be worth considering if you want to avoid an in-ear fit, though comfort will depend on your ears and how the frame sits.
