QYGCKJ ERAZER XF23 is my pick among dssb earbuds for a library because its open-ear design can keep audio available without sealing off your surroundings. Acjohtin is the runner-up if your priority is a low-profile fit for sleep and a quieter bedtime environment.
• QYGCKJ ERAZER XF23 — best for library listening while staying aware of nearby activity; pick this if you want open-ear audio plus translation, calls, and music in one set.
• Acjohtin Invisible Sleep — best for bedtime and side sleeping; pick this if its flat in-ear shape and white-noise support suit your nighttime routine.
• EXZHIG Earbuds — best for calls and everyday wireless listening; pick this if you want six microphones, touch controls, and a stated 35-hour battery life.
• Yworlln AI Translation Earbuds — best for multilingual travel and meetings; pick this if you want several translation modes and an LCD power display.
The QYGCKJ ERAZER XF23 is my choice for a library-minded shopper who wants to hear audio without fully closing off the surrounding environment. Its open-ear design is the key distinction here. For quiet study, that can be useful when you want a lecture or language lesson playing while remaining aware of people moving nearby. It is not a substitute for headphones designed to block room noise.
This is a multifunctional set rather than a simple pair of music earbuds. The listed features include music playback, phone calls, and real-time translation, with support for 165 languages. The translation modes include a shared setup intended for two people to wear the device and converse across languages. That makes the XF23 more relevant to language practice, travel, or multilingual conversations than a typical library-only pick.
The product information specifies Bluetooth 5.4 and 16 mm dynamic speakers. In everyday terms, it can connect wirelessly to a phone or laptop, and its larger listed driver size is intended for stereo listening. The sheet describes the sound as having balanced mids and clear highs, but it does not provide independent sound measurements. I would treat the audio claims as a feature description, not a guarantee of how it will sound in a particular room.
The trade-off is focus. Open-ear listening can leave nearby sounds audible, which may be welcome for awareness but less helpful if you need to concentrate in a noisy space. Translation also depends on a compatible device and the relevant modes, so the XF23’s broader feature set may be unnecessary if you only want ordinary wireless headphones for library study. I recommend it for someone who values situational awareness and translation in the same device.
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

Acjohtin Invisible Sleep is designed around a different job: keeping earbuds low-profile and comfortable for bedtime. Its flat in-ear shape and soft silicone tips are meant to sit gently in the ear, with the product description specifically positioning the design for side sleepers. If you tend to listen to calming audio in bed, that shape is more directly relevant than an open-ear design or sport-focused earbuds.
The listed functions include Bluetooth audio, AI white-noise support, and a translation feature described as a one-month experience. The white-noise function is presented as the continuing sleep-oriented feature. The tips are also intended to create a gentle seal and reduce unwanted background sounds, including snoring and household noise. That is passive noise reduction from the fit, not a promise of silence.
The specifications list Bluetooth 6.1, touch control, and an average battery life of five hours. The included charging case is wireless-chargeable, and the set includes two sleep earbuds and a cable. For someone who listens as they settle down, the battery figure is worth considering: it is a more limited listed runtime than the longer-running options here. A compact sleep-focused set may still be a better fit than a larger all-purpose pair if sleeping comfort is the main concern.
The trade-off is that this is the most specialized option in the group. Its flat form and white-noise focus make more sense for bedtime than for commuting, calls, or library listening where you may want broader audio features. The translation function also has a stated limited experience period, unlike the always-available white-noise feature. I would choose Acjohtin for sleep comfort, not as my general-purpose pick for a study session.
EXZHIG’s earbuds are the straightforward everyday-listening option in this group. They use a semi-in-ear design, which sits partly outside the ear canal rather than relying on a fully inserted silicone tip. That could suit someone who finds deeper in-ear fits uncomfortable. The shape is also described as suitable for workouts, though the product sheet does not specify a particular fit for every ear.
For calls, EXZHIG lists six microphones and ENC noise cancellation. The stated purpose is to help make voices clearer and reduce distracting background noise, including wind during outdoor activities. Those features may be useful for calls between classes or a quick conversation during a commute. They do not amount to a claim that the earbuds will silence a library or cancel all surrounding sound.
The listed 13 mm dynamic drivers are intended for stereo playback, while Bluetooth 5.4 provides wireless connectivity. Touch controls handle functions such as volume, tracks, calls, and voice assistants. A charging case with an LED power display is included, and the stated average battery life is 35 hours. That combination makes this a practical choice for someone who wants music, calls, and fewer interruptions to recharge.
The main trade-off is that this model does not offer translation features or a sleep-oriented shape. Its semi-in-ear design may also allow more ambient sound through than a snug, sealing in-ear fit—helpful for awareness, but not ideal when you want strong passive isolation. If your search is for the best gaming headset for library use, I would not treat these as a dedicated gaming headset: the listed features focus on calls, music, and wireless listening, not gaming-specific functions. I recommend EXZHIG for routine calls and general listening rather than specialized translation or sleep use.
Yworlln’s NE68 is the feature-heavy translation option. It supports 165 languages and lists eight translation modes, including arrangements that pair an earbud with a mobile phone, free talk, and AI conversation. The product also describes photo translation, voice notes, and video subtitle generation. For travel or language learning, that range may matter more than a simple music-focused feature set.
The set also handles music playback and calls, and its touch screen is paired with an LCD display for power monitoring. Bluetooth 6.0 and compatibility with iOS and Android are specified, along with a stated battery life of up to 48 hours and a 1.5-hour charging time. These figures and functions make the NE68 the broadest listed toolkit for someone who wants more than translation alone.
Its translation claims include latency below half a second and accuracy up to 98 percent. Those are product claims rather than a guarantee for every language, conversation, or environment. The feature set also relies on a companion application: the setup description says to install the dedicated app and pair the earbuds. The app includes an anti-loss positioning function, which may help locate misplaced earbuds through a map interface.
The trade-off is complexity. With numerous modes and extra functions, there is more to configure than with earbuds focused on ordinary playback. That may be worthwhile for a traveler who expects to use translation regularly, but it is overkill for someone who mainly wants quiet study audio. I recommend Yworlln when multilingual conversations are the priority; for a library-first buyer, the simpler open-ear approach of the QYGCKJ is a more direct fit.
I compared the published features and specifications, focusing on fit, listening design, battery information, and practical uses such as study, sleep, calls, and translation.
The order reflects my independent editorial opinion about how well each set matches those needs.
No brand paid for placement.
For a library, I recommend the QYGCKJ ERAZER XF23 if you want open-ear listening and translation features while remaining aware of nearby activity. If you need a quieter seal against ambient sound, none of the listed products should be treated as a guaranteed noise-blocking solution.
Acjohtin Invisible Sleep is specifically positioned for side sleepers. Its flat in-ear shape and soft silicone tips are intended to reduce discomfort at bedtime, and it includes white-noise support.
QYGCKJ ERAZER XF23 and Yworlln AI Translation Earbuds both list support for 165 languages and real-time translation. Yworlln additionally lists eight modes and a companion application; QYGCKJ describes a shared design and several translation modes.
Yworlln lists up to 48 hours, while EXZHIG lists an average of 35 hours. Acjohtin lists an average of five hours. These are the product specifications, and actual runtime may vary with use.
My final recommendation for a library-focused shopper is the QYGCKJ ERAZER XF23: its open-ear design and mix of music, calls, and translation make it the most fitting choice here for listening while staying aware of the room.
