If you want over-ear comfort, longer listening from a single charge, and a wired option, choose Edifier V80; if you need compact in-ear earbuds with a charging-case display and Transparency Mode, choose 21X Earbuds. For big ears, my pick is the V80: its over-ear cups avoid the fit uncertainty of an in-ear tip, while the 21X makes more sense when pocketable earbuds matter most.
Edifier V80 vs 21X Earbuds at a Glance
• 21X Earbuds: Small in-ear design, ANC and Transparency Mode, plus a case with a battery display. The trade-off is a shorter 10-hour listening span per earbud charge and an IPX4 rating rather than full waterproofing.
• For big ears: The V80 is the more straightforward fit to consider because it sits over the ears; ear shape and comfort can still vary.
• Choose the V80 for long sessions, calls, travel, and switching between two connected devices. Choose the 21X for a compact everyday set with touch controls and awareness mode.
• Neither one is a substitute for the other’s format: the V80 is a foldable over-ear headset, while the 21X is a pair of true wireless in-ear earbuds.
The Edifier V80 is an over-ear Bluetooth headset built around extended listening and flexible connections. Its soft ear cushions and foldable design suit someone who wants headphones for a home office, a commute, or a long stretch of music and video. Because the cups sit around the ears rather than inside them, the V80 is the option I would start with for big ears. That design may feel less intrusive than an in-ear fit, though comfort depends on the individual.
Its battery figures are a practical advantage for listeners who would rather charge less often: up to 45 hours with ANC off, or up to 26 hours with ANC on. A 15-minute charge is specified to provide up to eight hours of use. Hybrid active noise cancellation has multiple modes, and the built-in microphone uses AI noise cancellation for calls. The stated 0.06-second low-latency feature may also appeal to someone watching video or gaming, though the sheet does not specify that every device or use will deliver the same experience.

The 21X Earbuds are true wireless in-ear headphones for someone who values a compact format and quick everyday controls. Their case includes an LED display showing the remaining battery for the earbuds and case, so you can check charge status without relying only on a phone. Opening the case is described as triggering one-step pairing, and touch controls handle playback, calls, track changes, and voice assistant access.
The earbuds offer ANC, ENC for calls, and Transparency Mode. That mix is useful when you want to reduce surrounding sound during focused listening, then let more of the environment through when walking or speaking with someone. The product sheet specifies up to 10 hours of listening on a charge and another 30 hours from the case, for up to 40 hours total. Bluetooth 5.3 is listed with a connection range of up to 33 feet, making the set suitable for ordinary phone, laptop, and TV listening within that range.
Their IPX4 water-resistance rating is intended for sweat and light rain, not immersion. The in-ear shape can be convenient for commuting, exercise, or carrying in a small bag, but it is also the key fit consideration for big ears: earbuds depend on how their tips and shape sit in each person’s ears. Skip the 21X if over-ear cups are your priority, you need a wired listening option, or you want a higher water-resistance rating than IPX4.
• Best fit to consider for big ears → Edifier V80. Its over-ear placement avoids relying on an earbud tip sitting securely inside the ear. It is still worth considering personal comfort and fit.
• Best for a compact carry → 21X Earbuds. The in-ear buds and charging case are the more portable style; the V80 folds for storage but remains an over-ear headset.
• Best for longer listening between charges → Edifier V80. It specifies up to 45 hours with ANC off and 26 hours with ANC on. The 21X offers up to 10 hours per earbud charge, with additional listening from the case.
• Best for checking remaining charge at a glance → 21X Earbuds. Its case has an LED display showing battery information for the case and earbuds.
• Best for switching between work devices → Edifier V80. Multipoint connection supports two connected devices, which can help when calls arrive on a phone while music or video is playing on a laptop.
• Best for awareness while moving → 21X Earbuds. Transparency Mode is specifically listed alongside ANC, giving you a listening mode intended to keep you more aware of your surroundings.
• Best for a wired listening option → Edifier V80. The V80 supports wired and Bluetooth listening; the 21X sheet describes wireless Bluetooth connectivity.
• Best for sweat and light-rain protection → 21X Earbuds. Their IPX4 rating is stated for those conditions. The V80 sheet does not provide an IP water-resistance rating.
The first question is fit, not a feature checklist. If big ears make in-ear comfort uncertain, an over-ear design is a sensible place to start. The V80’s soft cushions and over-ear placement are relevant here, while the 21X depends on an in-ear fit. Neither spec sheet can guarantee comfort for every listener, so treat the form factor as a personal decision rather than a universal promise.
Next, think about where you listen. The V80’s multipoint connection, foldable design, wired mode, and long stated battery life suit a routine that moves between a desk and travel. The 21X’s case display, touch controls, and Transparency Mode fit a routine centered on phone listening and carrying earbuds around. Their ANC features are not a basis for claiming that one blocks more sound than the other; the available details do not provide a direct noise-reduction measurement.
For someone searching for low latency Bluetooth earbuds for big ears, the V80 is the unusual fit in this pairing: it is not an earbud, but its stated 0.06-second low latency may interest video and gaming users who are open to an over-ear headset. The 21X lists reduced latency but gives no numerical latency figure. Similarly, neither product should be casually called the best Bluetooth headset for big ears without knowing the listener’s fit preferences. If the question is specifically about the best IPX7 waterproof kids headphones for big ears, neither sheet supports that description: the 21X is rated IPX4, and the V80 has no IP rating listed. Check the current price on Amazon if price is part of your decision.
I would choose the Edifier V80 for big ears because the over-ear design is the more direct fit to consider, and its long stated battery life, multipoint connection, and wired option make it versatile for extended use.
I would choose the 21X instead if compact earbuds, a battery-display case, touch controls, and Transparency Mode matter more.
For my priorities, the V80 is the more suitable all-day listening choice; the 21X is the more convenient pocketable one.
The V80 is over-ear, while the 21X sits in the ear. For someone concerned about in-ear fit, the V80 is the more natural one to consider, though comfort varies by person.
Do the Edifier V80 headphones last longer than the 21X Earbuds?
The V80 specifies up to 45 hours with ANC off and up to 26 hours with ANC on. The 21X specifies up to 10 hours from the earbuds, plus up to 30 additional hours from its case.
Both list active noise cancellation. The 21X also lists Transparency Mode and ENC, while the V80 specifies hybrid ANC with multiple modes and AI noise cancellation for calls. The supplied details do not establish which blocks more environmental sound.
No IPX7 rating is listed for either product. The 21X is rated IPX4, which is described for sweat and light rain; the V80’s sheet does not state an IP water-resistance rating.
