If you want a two-pair setup for discreet daytime listening and side-sleeping, choose Xmenha Mini Invisible; if you need a single sleep-focused pair with a stated eight-hour battery life, choose Piegricdiat Sleep Earbuds. For study, Xmenha’s mix of low-profile mini earbuds and short-stem earbuds is the more flexible option, while Piegricdiat puts more emphasis on sleep mode and a long continuous-wear session.
• Xmenha Mini Invisible’s strength: two pairs for different situations, including mini earbuds for side-sleeping and short-stem earbuds for daytime use. Trade-off: the supplied details do not state battery life for either pair.
• Piegricdiat Sleep Earbuds’ strength: a sleep-focused design, sleep mode, and a stated average battery life of eight hours. Trade-off: it is a single-pair setup rather than two pairs for switching between uses.
• For study: Xmenha offers more ways to choose a low-profile or short-stem fit; Piegricdiat may suit someone who prioritizes extended wear and disabling earbud buttons.
• Choose Xmenha if you want two styles and a discreet option for work, study, or side-sleeping.
• Choose Piegricdiat if sleep features, Bluetooth 5.3, and a stated eight-hour battery life matter most.
Xmenha is unusual because the set includes two specialized pairs rather than one. The mini earbuds are intended for side-sleeping, while the short-stem pair is meant for daytime use. That division gives you a practical way to choose between a low-profile fit for lying down and a different shape for work, commuting, or study. If you are looking for open ear earbuds for study, note that these are in-ear earbuds, not open-ear headphones.
The discreet design and noise-isolating tips are aimed at focused listening without a conspicuous profile. For study, that may appeal if you want a compact in-ear option for listening to audio while working through notes or studying in a shared setting. The product information lists Bluetooth 5 and a balanced armature driver, but it does not give a battery-life figure. Its two-pair arrangement allows you to switch while one pair recharges, though that is not the same as a stated total runtime.

Piegricdiat is the more sleep-centered design. Its stated features include soft silicone eartips and caps, a sleep mode that disables the earbud buttons, Bluetooth 5.3, and an average battery life of eight hours. The sleep-mode detail is especially concrete: once enabled, you control the earbuds through your phone rather than the earbud buttons. That can matter when you are lying on your side and want to reduce accidental button presses.
For study, the single-pair design may appeal if your priority is a long stretch of listening without frequent charging. The product information also describes a built-in noise-reduction microphone and claims clearer calls, so it may be worth considering if call capability matters alongside listening. Still, a microphone specification does not establish that calls will be crystal clear in every room or with every phone. If you are searching for crystal clear calls in ear earbuds for study, treat the microphone as a potentially useful feature, not a guarantee of call quality. The same goes for crystal clear calls kids headphones for study: the supplied information does not establish a specific result for children or a particular listening environment.
I’d lean toward Piegricdiat if sleep mode, Bluetooth 5.3, and a stated eight-hour battery life fit your routine. I’d look elsewhere if you want two separate pairs for switching between sleep and daytime use, or if you need a detailed battery comparison across multiple earbuds. Its product information lists pink and IPX6 waterproofing, but the description’s underwater-use claims should not be mistaken for details about call quality or suitability for every activity.
Side-by-Side: Which Should You Choose?
• Best for a two-pair setup → Xmenha Mini Invisible. The set includes a mini pair for side-sleeping and a short-stem pair for daytime.
• Best for sleep mode that disables earbud buttons → Piegricdiat Sleep Earbuds. The feature is designed to prevent accidental button presses, with phone control remaining available.
• Best for choosing between two earbud styles → Xmenha Mini Invisible. Its pairs are intended for different use situations.
• Best for Bluetooth 5.3 → Piegricdiat Sleep Earbuds. Xmenha lists Bluetooth 5.
• Best fit for discreet daytime use as well as sleep → Xmenha Mini Invisible. Its features specifically describe a daytime short-stem pair alongside the sleep-oriented mini pair.
• Best if a built-in noise-reduction microphone is a priority → Piegricdiat Sleep Earbuds. Its supplied details mention one; Xmenha’s do not.
• Best if you want a listed IPX6 rating → Piegricdiat Sleep Earbuds. That specification is provided for Piegricdiat, not Xmenha.
For study, I’d choose Xmenha Mini Invisible if I wanted the flexibility of two pairs: a mini option for lying down and a short-stem option for daytime listening. That variety is its strongest practical advantage.
I’d choose Piegricdiat instead if a stated eight-hour battery life and button-disabling sleep mode mattered more to me than having two styles.
My overall pick is Xmenha for the broader mix of study, work, and side-sleeping use, with the important caveat that its battery life is not specified.
Both products describe features for side-sleeping. Xmenha includes a mini pair intended for that use, while Piegricdiat describes soft silicone tips and a sleep mode. The better fit may come down to which shape feels comfortable in your ear.
Which has longer battery life?
Piegricdiat lists an average battery life of eight hours and says it can be used continuously for more than six to eight hours. The supplied information does not state battery life for Xmenha, so there is no supported runtime comparison between the two.
No. Both are described as in-ear earbuds. Xmenha offers a low-profile mini pair and a short-stem pair, but neither product is identified as an open-ear design.
Piegricdiat’s product details mention a built-in noise-reduction microphone, while Xmenha’s supplied details do not specify a microphone. That makes Piegricdiat the more clearly documented option for calls, but the information does not guarantee crystal-clear call performance.
