If you want discreet earbuds with stated playtime and automatic reconnection, choose Xmenha Smallest Invisible Earbuds; if you need a low-profile design specifically described for small ear canals and side sleeping, choose Unremittingly mini earphones ，Mini. For a big head, neither is an over-ear option: both sit inside the ears, so the decision comes down to the in-ear fit and features you need.
• Xmenha’s biggest strength: The product details specify 6–7 hours of playtime per charge and up to 35 hours with the charging case. Trade-off: There’s no stated water-resistance rating.
• Unremittingly’s biggest strength: Its low-profile shape is described as suited to small ear canals and lying on your side, and it has an IPX5 rating for sweat, splashes, and light rain. Trade-off: The provided details don’t specify battery life or Bluetooth version.
• Fit and discretion: Both are tiny, in-ear designs. Xmenha emphasizes a very small, barely noticeable profile; Unremittingly makes the small-canal and side-sleeping use cases more explicit.
• Controls and pairing: Xmenha lists one-key controls and describes automatic reconnection after the first pairing. Unremittingly lists touch controls but does not provide the same pairing detail.
• Who should choose Xmenha: Someone who wants stated battery figures, straightforward controls, and a discreet earbud for everyday listening.
• Who should choose Unremittingly: Someone who prioritizes a small-canal fit, side-sleeping comfort, and a stated level of sweat and splash protection.
Xmenha is the more spec-specific choice for someone who wants a miniature earbud without giving up a clear idea of listening time. Its product information lists 6–7 hours of playtime from the earbuds and up to 35 hours when the charging case is included. The listed charging time is 1.5 hours. Those figures make it easier to plan for a workday or a longer stretch away from a charging point, though actual use can vary.
The setup is also described in practical terms. For the initial connection, take the earbuds out of the case, turn on Bluetooth, and pair with “X21.” After that, opening the charging case is described as prompting the earbuds to reconnect to the phone used previously. The earbuds use Bluetooth 5.1 according to the description, while another feature listing identifies Bluetooth 5.0. That discrepancy means I would treat the exact Bluetooth version cautiously. Either way, the listed details support wireless pairing with iOS, Android, and Windows devices.

Unremittingly is more direct about two use cases: small ear canals and listening while lying on your side. Its slim, low-profile in-ear body is described as sitting close to the ear rather than protruding. The product description says the shape is intended to avoid pressure against a pillow, which makes it a more targeted option for someone who listens to music, white noise, or audiobooks in bed.
That fit description may also appeal to someone who finds larger earbuds uncomfortable. The product is presented as lightweight and snug for small ear canals, with touch controls for answering calls, pausing or playing audio, and changing songs. Those are useful basics for everyday listening, although the provided specifications do not say how long the battery lasts, how quickly it charges, or how long the case extends listening time. If battery planning is a deciding factor, that missing information matters.
Its clearest additional feature is an IPX5 rating, described as protection against sweat, splashes, and light rain. That can be relevant for commuting or workouts where moisture is a concern. It is not a reason to assume the earbuds are suitable for swimming or immersion; the supplied description only supports sweat, splashes, and light rain. Skip Unremittingly if you need published battery-life figures before choosing.
• Best for stated battery life → Xmenha Smallest Invisible Earbuds. Its listed figures are 6–7 hours per charge and up to 35 hours with the case. Unremittingly’s supplied details don’t include comparable numbers.
• Best for side sleeping → Unremittingly mini earphones ，Mini. Its slim shape is specifically described as designed to reduce pillow pressure when lying on your side.
• Best for small ear canals → Unremittingly mini earphones ，Mini. The product is explicitly presented as a fit for smaller canals. Xmenha is described as very small, but the provided details don’t make the same specific fit claim.
• Best for a stated moisture rating → Unremittingly mini earphones ，Mini. IPX5 is listed for sweat, splashes, and light rain. Xmenha’s supplied details don’t state a water-resistance rating.
• Best for automatic reconnection details → Xmenha Smallest Invisible Earbuds. The description explains that the earbuds reconnect to the previously paired phone after the case is opened.
• Best for simple listed call and playback controls → Either, with different control styles. Xmenha describes one-key operation; Unremittingly lists touch controls. Choose based on which control approach sounds more convenient to you.
• Best for a discreet in-ear profile → A close call. Both are described as mini and low-profile. Unremittingly emphasizes a flush shape, while Xmenha emphasizes that the earbuds are very small and barely noticeable.
• Best over ear headphones for big head → Neither. Both products are in-ear earbuds, not over-ear headphones. If your concern is headband pressure or over-ear sizing, these designs don’t address that issue.
Start with fit, not the word “invisible.” Both products are compact in-ear models, but small earbuds do not automatically fit every ear comfortably. Unremittingly makes the clearest claim for small ear canals and side sleeping. Xmenha emphasizes a tiny profile and long-wear comfort. Those descriptions can help narrow the choice, but they can’t guarantee a comfortable fit for a particular person.
Next, think about where you’ll use them. For a commute or a workout where sweat and light rain may be part of the day, Unremittingly has the more relevant stated feature: IPX5 protection. For long stretches of listening, Xmenha gives you more planning information through its stated playtime and case total. If you listen in bed, the pillow-pressure design claim gives Unremittingly a more specific reason to consider it.
Controls are another small but meaningful difference. Xmenha’s one-key approach is described for calls and playback, including a double click to move to the next song. Unremittingly uses touch controls for common actions. Neither set of supplied details says how the controls behave with every phone or app, so treat these as descriptions of the intended basic functions rather than a promise about every setup.
Sound expectations deserve restraint, too. Xmenha lists a dynamic driver, a frequency range, and a graphene diaphragm in its description. Those are pieces of product information, not a substitute for listening impressions or a guarantee of a particular sound signature. Unremittingly’s supplied information focuses more on fit, moisture protection, and convenience than on audio specifications. If you’re choosing mainly for detailed sound quality, the information here doesn’t establish a clear winner.
Finally, don’t mistake either design for an over-ear solution. People searching for the best over ear headphones for big head may be trying to solve a headband-fit problem. These earbuds avoid a headband altogether, but they still depend on a comfortable fit inside the ear. Similarly, the phrase memory foam ear cushions earbuds for big head doesn’t describe either product: neither product’s supplied details mention memory foam or ear cushions. And neither listing provides a transparency mode, so shoppers looking for the best transparency mode true wireless earbuds for big head should look for a model whose details explicitly confirm that feature.
I’d choose Xmenha if I wanted the more clearly documented listening schedule: up to 6–7 hours per charge and up to 35 hours with the case. I’d choose Unremittingly if small-canal fit, side sleeping, or an IPX5 rating mattered more than battery figures. For a big head, I’d make the decision based on ear fit rather than head size, since both are in-ear designs. My pick is Xmenha for its more complete battery and pairing details.
FAQ
Which earbuds are better for side sleeping?
Do Xmenha earbuds last longer than Unremittingly?
Xmenha lists 6–7 hours of playtime per charge and up to 35 hours with the charging case. The supplied Unremittingly details do not include battery-life figures, so there isn’t enough information here to compare total listening time.
They have an IPX5 rating, described as protection from sweat, splashes, and light rain. The supplied details do not claim that they can be submerged or used for swimming.
Neither is an over-ear headphone, so headband size is not the deciding factor.
