If you want sleep-focused earbuds with a stated four-hour listening time per earbud and simple touch controls, choose ANSTEN Sleep Headphones; if you need a tiny design for side sleeping and want Bluetooth 5.4 for listening to audio and video, choose MZQYRVK Mini Invisible Sleep. For video calls, I’d lean toward MZQYRVK for its stated call use and newer Bluetooth version, while ANSTEN has clearer call-control details.
• ANSTEN’s biggest strength: soft silicone tips, passive noise reduction and touch controls that can answer calls; its main trade-off is a stated playtime of up to four hours per earbud.
• MZQYRVK’s biggest strength: a small, discreet in-ear design and Bluetooth 5.4; its main trade-off is that the provided specifications don’t state a playback time or describe its call controls in detail.
• Choose ANSTEN if you want sleep-oriented noise masking, a displayed case battery level and clearly specified playback time.
• Choose MZQYRVK if you prioritize a tiny profile for side sleeping and want to use earbuds for music, videos and casual calls.
ANSTEN is the more explicitly sleep-oriented option. It uses soft silicone ear tips and a rounded in-ear shape, with a design intended to stay comfortable when lying on your side. Its noise reduction is passive: the seal of the ear tips helps limit unwanted sound, and audio can provide additional masking. It does not have active noise cancellation, so don’t expect it to electronically erase surrounding noise.
The stated listening time is up to four hours for a single earbud. The charging case has a digital power display, and the earbuds use Bluetooth 5.3. Touch controls handle tasks including changing or pausing music and answering calls. Those features make ANSTEN a straightforward pick for someone who wants a compact bedtime listening setup and a quick way to take a call without reaching for a phone.

MZQYRVK emphasizes a small, discreet profile, with a soft silicone loop intended to help the earbuds sit securely while you lie on your side. It is presented for sleep, naps, travel and quiet rest. The case has a digital display that shows the left and right earbud battery levels separately, which offers a more detailed view than a single general battery indicator.
The earbuds use Bluetooth 5.4 according to the feature description, and the product is described as suitable for music, videos, casual mobile games and calls. It also supports using one earbud on its own. That flexibility could suit someone who wants one device for a bedtime podcast, a video on the go and occasional voice chat.
For video calls, MZQYRVK makes the more direct multi-use case, but there’s no detailed microphone specification or call-control description to confirm how it will perform in meetings. Treat the Bluetooth and call-use claims as features, not a guarantee of clearer calls. Skip it if you want a clearly stated listening time or if you prefer the straightforward touch controls and sleep-focused noise-masking details offered by ANSTEN.
• Best for a stated listening duration → ANSTEN Sleep Headphones. The listed figure is up to four hours per earbud. MZQYRVK’s supplied information does not specify playback time.
• Best for Bluetooth version → MZQYRVK Mini Invisible Sleep. Its feature description says Bluetooth 5.4, compared with Bluetooth 5.3 for ANSTEN.
• Best for touch controls → ANSTEN Sleep Headphones. Touch controls are described for music and answering calls; MZQYRVK lists button control.
• Best for checking each earbud’s charge → MZQYRVK Mini Invisible Sleep. Its display is described as showing left and right earbud power separately. ANSTEN also has a digital case display, but the sheet doesn’t specify separate levels.
• Best for sleep-focused noise masking → ANSTEN Sleep Headphones. It has sealed ear tips and passive noise reduction, though not active noise cancellation.
• Best for one-earbud listening → MZQYRVK Mini Invisible Sleep. Its product details explicitly describe independent mono-earbud use.
• Best if you want sleep comfort to lead the decision → either, for different reasons. Both describe soft silicone and a side-sleeper-friendly form; ANSTEN gives a clearer playtime figure, while MZQYRVK stresses its tiny profile.
• Best wireless headphones for video calls → neither is a sure thing from the available specifications. MZQYRVK is explicitly positioned for calls and office voice chat; ANSTEN specifies touch-to-answer. Neither sheet provides enough microphone detail to promise a particular call experience.
The phrase “best rechargeable open ear earbuds for video calls” may sound appealing if you want to hear your surroundings, but neither of these is an open-ear design. Both are in-ear earbuds. Likewise, I wouldn’t call either one the best sweatproof kids headphones for video calls: the provided information does not specify sweat resistance or a child-focused fit. Those are important distinctions if calls are your main use rather than bedtime listening.
I’d choose MZQYRVK if my main goal were a discreet pair for sleep that could also handle casual video and voice use. Its Bluetooth 5.4 feature and stated call use give it the more flexible pitch for video calls, although the missing playback-time and microphone details keep my recommendation measured. If I wanted a sleep-first pair with a stated four-hour listening duration and touch-to-answer controls, I’d pick ANSTEN instead. For video calls specifically, my choice is MZQYRVK Mini Invisible Sleep, based on the use cases described—not on any promise of superior microphone quality.
Both are described as small in-ear designs with soft silicone intended to make side sleeping more comfortable. ANSTEN gives more detail about its silicone ear tips and passive noise reduction; MZQYRVK emphasizes its tiny, discreet profile and silicone loop.
MZQYRVK is explicitly described for calls and office voice chat, while ANSTEN specifies touch controls for answering calls. Neither product sheet gives detailed microphone specifications, so the information does not establish which will sound clearer to other people.
No active noise cancellation is specified for either model. ANSTEN explicitly states that it uses passive noise reduction, relying on the ear-tip seal rather than ANC. Don’t expect either pair to electronically cancel surrounding sound based on these details.
ANSTEN lists up to four hours of continuous play for a single earbud. The provided MZQYRVK information does not give a playback-duration figure, so there isn’t enough detail for a direct battery-life comparison.
