If you want tiny earbuds with longer total playback from the charging case, choose Loluka Invisible Earbuds Sleep; if you need sleep earbuds with passive noise reduction and a power display, choose ANSTEN Sleep Headphones. For airplane travel, I’d lean toward Loluka for its discreet, single-ear option and longer case-supported listening, while ANSTEN makes more sense when a soft, sealed fit for side sleeping matters most.
Loluka Invisible Earbuds Sleep vs ANSTEN Sleep Headphones at a Glance
• ANSTEN’s biggest strength: soft silicone tips and passive noise reduction, with a case display for checking battery power. Its main trade-off is up to four hours of continuous playback per earbud.
• Choose Loluka if discreet size, single-ear use, and more total playback between case charges are priorities.
• Choose ANSTEN if side-sleeping comfort, sealed ear tips, and passive noise blocking matter more than longer individual listening sessions.
• These are both compact Bluetooth earbuds, but their designs point toward different routines. Loluka emphasizes small size, flexible single-ear use, and a case that extends overall playback. ANSTEN puts more emphasis on soft silicone, noise masking, and comfort when lying on your side. Neither product lists active noise cancellation, so neither should be treated as a way to silence an airplane cabin completely.
Loluka is the more discreet option of the two. Its very small, lightweight in-ear design is intended to sit securely in the ear, and the product information describes the fit as suitable for longer wear. That may appeal to someone who dislikes bulky headphones or wants an earpiece that is less noticeable during work, travel, or quiet listening. The product lists a rounded tip and touch controls, with one-key operation for playback and calls.
The battery figures suit people who can make use of the charging case between listening periods. Loluka lists up to five hours of playback from a single charge and up to 35 hours with the case’s additional charging capacity. Those are different kinds of endurance: five hours is the stated single-session limit, while 35 hours represents the combined use supported by the case. For a long travel day, the extra case capacity could be useful if you can pause and recharge the earbuds between stretches of listening.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-18 · 8 min read · Independent comparison
Who should skip it: Skip Loluka if passive noise blocking is a must; its listed noise control is none, and it does not claim active noise cancellation. Also think carefully about the five-hour single-charge limit if you want uninterrupted listening for longer than that.
ANSTEN is the more sleep-focused design. Its soft silicone ear tips and ergonomic fit are described as suitable for lying on your side without putting pressure on the ears. That detail matters if you listen in bed and find that larger headphones or protruding earbuds press uncomfortably against a pillow. The product is still an in-ear device, but its stated emphasis is on soft cushioning and a sealed fit rather than on being nearly unnoticeable for general everyday wear.
Its noise approach is passive. Sealed ear tips and passive noise reduction are intended to reduce unwanted sound, while a noise-masking system can pair with audio to make distractions less prominent. This is not active noise cancellation. For an airplane passenger, that distinction is important: the listed design may help mask or soften some surrounding noise, but it should not be expected to electronically cancel cabin sound.
ANSTEN lists up to four hours of continuous playback from one earbud. The charging case is described as providing up to 40 hours of battery life, and its digital power display lets you check the case’s battery level. The display is a practical convenience when you want to know whether the case needs charging before a night’s sleep or a trip. Bluetooth 5.3 and a listed 15-meter range round out the connectivity details. Touch controls handle music and calls, and the product says the controls do not make a sound when touched.
Who should skip it: Skip ANSTEN if you need more than four hours of uninterrupted listening from a single charge or expect active noise cancellation. Its case-supported total is substantial on paper, but that does not remove the need to recharge the earbuds during a long listening stretch.
• Best for longer playback from one charge → Loluka Invisible Earbuds Sleep. It lists up to five hours per earbud, compared with up to four hours for ANSTEN.
• Best for longer stated case-supported playback → ANSTEN Sleep Headphones. Its case is described as providing up to 40 hours, compared with Loluka’s listed 35 hours with the case.
• Best for using one earbud at a time → Loluka Invisible Earbuds Sleep. The product specifically says either earbud can be selected for standalone use.
• Best for side sleeping → ANSTEN Sleep Headphones. Its soft silicone tips and fit are described with side-sleeping comfort in mind.
• Best for passive noise reduction → ANSTEN Sleep Headphones. It lists sealed tips and passive noise reduction; Loluka lists no noise control.
• Best for checking case battery at a glance → ANSTEN Sleep Headphones. Its case includes a digital power display.
• Best for airplane travel when discreet size and case-supported listening lead → Loluka Invisible Earbuds Sleep. Its small design and up-to-35-hour case-supported playback are useful considerations, though it does not list noise reduction.
• Best for Bluetooth version on the spec sheet → ANSTEN Sleep Headphones. It lists Bluetooth 5.3, while Loluka lists Bluetooth 5.1.
For movies, either could be considered as a compact Bluetooth listening option, but the stated playback limit matters if you plan to watch for several hours without a break. Loluka’s five-hour single-charge figure gives it a modest advantage over ANSTEN’s four-hour figure for that kind of session. Neither sheet specifies a dedicated movie mode, so I would not assume either has a special feature for syncing dialogue or video.
Neither is an over-ear model, so shoppers searching for the best comfortable on ear headphones for focus or the best USB-C charging over ear headphones should note that these picks do not match that form factor. The supplied information does not specify a USB-C charging connection, either. These are small in-ear Bluetooth earbuds, with the choice coming down mainly to discreet everyday use versus sleep-oriented fit and passive noise reduction.
I would choose Loluka Invisible Earbuds Sleep for airplane travel if my priorities were a tiny in-ear design, the option to use one earbud, and longer playback per charge. Its 35-hour case-supported figure is useful for planning, but it does not mean 35 uninterrupted hours in the ears.
I would choose ANSTEN instead for sleeping on my side or for a sealed fit that offers passive noise reduction. In my opinion, Loluka is the more flexible travel pick; ANSTEN is the more focused bedtime pick.
Think about how you listen before deciding. If your trip involves several hours of continuous audio, compare the individual playback figures first: Loluka lists up to five hours, while ANSTEN lists up to four. Case-supported totals are useful for repeated listening with breaks, but they are not a substitute for a longer single-charge runtime.
Also consider what you mean by “noise reduction.” ANSTEN’s passive design relies on sealed tips and fit, while the product explicitly says it does not have active noise reduction. Loluka lists no noise control. If your main goal is to block cabin noise, these specifications do not establish that either pair will fully meet it.
For sleep, fit is personal, but the stated design gives ANSTEN the clearer case for side sleeping. For a discreet earpiece that can be used one ear at a time, Loluka has the more directly relevant feature. If you want to compare current purchasing details, check the current price on Amazon; the specifications here do not determine which option is the better value for you.
