If you want a foam-based way to improve the fit of compatible wired or wireless earphones for a big head, choose COMPLY 100; if you need complete wireless earbuds designed for side sleeping, choose Amikovee Sleep Earbuds. The key difference is what you are buying: replacement tips for earbuds you already own, or a separate Bluetooth earbud set with a charging case. Neither is a universal fit, so compatibility and comfort needs should guide the decision.
• COMPLY 100’s biggest strength: body-heat-activated memory foam is designed to conform to the ear canal, helping create a secure seal and reduce background noise. Trade-off: these are replacement tips, not headphones, and fit only select compatible earphones.
• Amikovee Sleep Earbuds’ biggest strength: a small, in-ear wireless design with touch controls, adaptive noise cancellation, and a charging case. Trade-off: the listed earbud battery life is 3.5 hours, so longer listening depends on the case and charging breaks.
• Choose COMPLY 100 if you already have compatible earphones and want to change their fit or seal.
• Choose Amikovee if you want a standalone Bluetooth option for sleep, travel, or everyday listening.
• For a big head, neither product changes headband size: COMPLY 100 may help with ear-canal fit, while Amikovee avoids a headband altogether.
COMPLY 100: Who It's For
The seal matters for more than stability. COMPLY says the foam is intended to isolate background noise and support bass and clarity at lower listening volumes. That makes these tips worth considering if you already like your earphones but struggle with fit, pressure, or distractions around you. They may also suit someone searching for bone conduction headphones for big head if the real issue is earbud comfort rather than headband fit—but these are not bone-conduction headphones. They are foam tips for compatible in-ear earphones.
Compatibility is the first practical check. The tips are listed for select Etymotic Research, ISOtunes Pro, Westone, Klipsch, and Jays models, among others. That does not mean every earphone from those brands will fit. Confirm that your specific model is compatible before buying. The large size is another consideration: the sheet identifies the pack as large, but does not provide a range of ear-canal sizes or an adjustment system.
Care is straightforward but worth noting. The foam can be gently cleaned with warm water and a soft cloth; alcohol-based cleaners and lotions should be avoided because they can damage the material. The main trade-off is that COMPLY 100 does not provide audio, Bluetooth, noise-control electronics, or a charging case. It modifies the fit of earphones you already own.
Who should skip it: Skip COMPLY 100 if you need a complete wireless headset, if your earbuds are not compatible, or if large foam tips are not the size you need.
Amikovee Sleep Earbuds are a complete in-ear Bluetooth set rather than an accessory for other headphones. Their small, curved design is described as intended for side sleepers, with a multi-point fit intended to hold the earbuds in place. For someone who finds a headband awkward or uncomfortable, that in-ear format may be a more relevant starting point than conventional over-ear headphones. It also makes these a possible option for someone looking for the best wireless headphones for big head without a headband pressing around the head.

The sleep focus is paired with features for other settings. Adaptive noise cancellation is listed for reducing surrounding noise, while Ambient Aware mode is described as a way to hear more of the environment, such as when jogging. Touch controls let the wearer switch modes without using a wired remote. These functions make the earbuds more versatile than a sleep-only accessory, though the listed features do not establish how much noise they block in any particular room.
Battery details need a close read. The earbuds are listed with 3.5 hours of average battery life, and the charging case with 20 hours of average battery life. The case has an LED power display, and the product information lists a two-hour charge time; the feature description also says Type-C recharging takes 60 minutes. Because those stated recharge times differ, I would check the included instructions for the exact charging expectation. In practical terms, the case adds charging capacity, but a single earbud charge is not a full night of continuous use based on the stated average.
Bluetooth 5.4 and one-tap pairing are listed, along with touch control and a 10-yard wireless range. The 13 mm dynamic drivers are paired with a stated 20 Hz–20,000 Hz frequency range. Those specifications describe the audio hardware, but they do not by themselves guarantee a particular sound character or fit. The product also includes a one-year manufacturer warranty. Its trade-off versus COMPLY 100 is that it is a full electronic product with limited stated earbud runtime per charge, rather than a simple fit upgrade for a set of compatible earphones.
Who should skip it: Skip Amikovee if you want replacement tips for earphones you already own, need a stated volume limiter, or require more than 3.5 hours of earbud runtime between charging opportunities.
Side-by-Side: Which Should You Choose?
• Best for improving the seal on compatible earphones → COMPLY 100. Its heat-activated memory foam is designed to mold to the ear canal and hold the earphone more securely.
• Best for a complete wireless setup → Amikovee. It includes Bluetooth earbuds, touch controls, adaptive noise cancellation, and a charging case.
• Best for someone who already owns compatible earbuds → COMPLY 100. You keep your existing audio device and change only the ear tips.
• Best for side-sleeping use → Amikovee. Its compact, curved in-ear design is specifically described for side sleepers.
• Best for avoiding a headband → Amikovee. It is an in-ear wireless design, though the listed information does not guarantee a fit for every ear.
• Best for a personalized foam fit → COMPLY 100. Body heat activates the foam so it can conform to the ear canal.
• Best when you want an ambient-awareness option → Amikovee. Ambient Aware mode is listed for situations such as jogging.
• Best for keeping the listening setup simple → COMPLY 100. There is no Bluetooth pairing or charging case to manage, but you must already own compatible earphones.
Before choosing COMPLY 100, identify the exact earphone model you plan to use. The compatibility list covers selected models and brands, not every earphone with a similar shape. Also consider whether large tips suit your ears. The foam’s moldable design is meant to improve the seal, but that does not remove the need for a suitable starting size. If the tips do fit, their passive isolation and secure grip may be more useful to you than buying a separate headset.
Fit claims should also be separated from head size. A big head can make headbands feel restrictive, but neither product is a headband. COMPLY 100 changes the fit of compatible in-ear earphones; Amikovee supplies its own in-ear buds. Neither sheet gives a head-size range, nor does either specify adjustable earbud sizing. For shoppers who want the best wireless headphones for big head, the useful question here is whether you prefer an in-ear design—not whether either product has a larger headband.
Finally, compare what each purchase actually replaces. COMPLY 100 is a small set of foam tips, not a standalone listening device. Amikovee is a wireless headset set with a case, but its battery and charging details matter to how you plan to use it. If you are weighing value, check the current price on Amazon using the page’s price button, then compare it with what you already own and the features you will use. No price alone can settle the fit and runtime trade-offs.
My Verdict
In my opinion, I would choose Amikovee Sleep Earbuds if I needed a complete wireless option for side sleeping and did not want a headband. I would choose COMPLY 100 only if I already owned compatible earphones and wanted a better-sealing foam tip.
For a big head, I would not treat either product as a guaranteed fit solution: both sit in the ear, and neither provides a head-size specification. My final pick for the broader sleep-and-wireless use case is Amikovee, with the 3.5-hour earbud runtime firmly in mind.
No. COMPLY 100 is a pack of replacement foam tips for select earphones. Amikovee is a complete Bluetooth earbud set with a charging case.
Amikovee is specifically described as having a compact in-ear design intended for side sleepers. COMPLY 100 may change the fit of compatible earphones, but it is not itself a sleep earbud or a complete headset.
Volume limiting is not listed among the provided features. If that function is essential, verify it directly before choosing these earbuds; the available details do not confirm that they include it.
The listed average battery life for the earbuds is 3.5 hours, with 20 hours of average battery life stated for the charging case. The case provides additional charging capacity, rather than extending one uninterrupted earbud charge to 20 hours.
