If you want swimming-ready listening with phone-free MP3 playback for children, choose Pmjebe Bone Conduction Swimming; if you need clip-on open-ear headphones for everyday calls and workouts, choose ZKBSIAXD Open Ear. Pmjebe’s key advantage is its built-in 8GB player and stated IP68/IPX8 waterproofing; ZKBSIAXD offers a clip-on design, touch controls, and a charging case. The right pick depends less on which sounds more appealing on paper than on whether swimming or routine Bluetooth use is the priority.
• Pmjebe Bone Conduction Swimming: Its built-in 8GB MP3 player and stated ability to submerge to 5 meters for up to 24 hours make it the swimming-focused choice. The trade-off is that its listed battery life is 10 hours, with no charging-case total provided.
• ZKBSIAXD Open Ear: Its clip-on design and case-supported total-playtime claim suit everyday workouts, commuting, and calls. The trade-off is a lower water-resistance rating, IPX4, and six hours of playback per charge.
• Choose Pmjebe if you want local music playback without carrying a phone into the water.
• Choose ZKBSIAXD if you want Bluetooth open-ear listening, touch controls, and call-focused features for use outside the pool.
Pmjebe is built around a particular use case: listening while swimming, with running and cycling also listed as suitable activities. Its open-ear bone-conduction design is intended to leave the ear canal unobstructed, so the headphones do not use the traditional in-ear fit. That may appeal to someone who dislikes the feeling or pressure of in-ear headphones. The design also aims to let the wearer remain more aware of nearby sounds during land-based activities.
The most practical distinction is its combination of Bluetooth and a built-in 8GB MP3 player. For listening without a phone nearby, the stored-music mode is the more relevant feature: the product lists support for MP3, M4A, WAV, WMA, AAC, and FLAC files. The listed capacity is enough for a personal library, though how many tracks fit will depend on the files. Bluetooth 5.4 is specified in the feature list, while the product details also list Bluetooth 5.3, so I would not treat the exact version as a deciding point. Either way, its standout use is local playback for swimming, not a claim that Bluetooth itself will provide phone-free underwater listening.
Pmjebe lists 10 hours of battery life and IP68/IPX8 waterproofing, including submersion up to 5 meters for up to 24 hours. Those are the figures that separate it from the other option here. It also lists 16mm drivers, button controls, and a 33-foot Bluetooth range. I would consider it for a child who swims and needs a way to play stored audio, while keeping in mind that the product’s age-range field says “Adult.” That makes it important for a parent to judge fit and suitability rather than assuming it is child-sized.

Who should skip it: Skip Pmjebe if you mainly want clip-on earbuds for calls and general Bluetooth listening, or if IPX4-level splash resistance is enough and you do not need a built-in MP3 player.
ZKBSIAXD takes a different approach: the earbuds clip on rather than sitting inside the ear canal, and Bluetooth is the listed listening connection. The open-ear format may suit people who want to keep their ears uncovered during a workout or commute. The product describes the clip-on fit as secure for activities such as running and gym sessions. That is a design intention, not a guarantee that the fit will feel equally secure on every person.
For calls, ZKBSIAXD lists ENC noise cancellation, intended to reduce background noise during conversations. Its feature sheet claims suppression of up to 90%, but that figure should be understood as a stated specification rather than a promise of perfect call clarity in every setting. The headphones also offer touch controls for playback, volume, calls, and voice-assistant access. They are listed as compatible with Bluetooth-enabled devices, including iOS, Android, iPad, and Windows PC in the feature description. If you want open-ear headphones for switching between music and calls, this set of controls may be more relevant than Pmjebe’s swimming features.
Battery life needs a little context. ZKBSIAXD lists up to six hours of continuous playback on a charge and up to 300 hours total with the charging case. The 300-hour figure is the combined total claimed with case power, not continuous listening time from the earbuds alone. The listed water resistance is IPX4, which is aimed at sweat and light rain rather than submersion. Bluetooth 6.0 and a 15-meter connection range appear in the feature sheet, while product details list Bluetooth 5.4; I would focus on the stated wireless range and intended use rather than choosing based on the version number alone.
I would consider ZKBSIAXD for someone who wants an open-ear option for everyday Bluetooth listening, office calls, or exercise where splash resistance is sufficient. It may also suit a child who needs headphones for non-swimming activities, but there is no child-specific sizing information in the provided product details. For a search like “best on ear headphones for children,” note that these are described as clip-on, open-ear earbuds—not conventional on-ear headphones.
Who should skip it: Skip ZKBSIAXD if you need headphones for swimming or want more than six hours of playback between charges without relying on the case.
• Best for swimming → Pmjebe Bone Conduction Swimming. Its stated IP68/IPX8 rating and submersion specification are intended for swimming; ZKBSIAXD is listed at IPX4.
• Best for phone-free listening in the water → Pmjebe Bone Conduction Swimming. Its 8GB built-in MP3 player provides local playback, which is the feature to focus on when a phone is not part of the listening setup.
• Best for calls and touch controls → ZKBSIAXD Open Ear. It lists call management, touch controls, and ENC for calls; Pmjebe lists push-button controls.
• Best for longer listed playback per charge → Pmjebe Bone Conduction Swimming. Its listed battery life is 10 hours versus six hours for ZKBSIAXD.
• Best for case-supported total battery claims → ZKBSIAXD Open Ear. Its stated 300 hours includes the charging case, while Pmjebe’s sheet lists 10 hours without a case-based total.
• Best for a clip-on fit → ZKBSIAXD Open Ear. Its design is specifically described as clip-on; Pmjebe uses a flexible open-ear bone-conduction frame.
• Best for a broad range of stored audio formats → Pmjebe Bone Conduction Swimming. It lists MP3, M4A, WAV, WMA, AAC, and FLAC support through the built-in player.
• Best for the “best gaming headset for children” search → neither is a dedicated gaming headset. ZKBSIAXD lists low-latency Bluetooth in its feature description, but neither product sheet identifies gaming as a primary use. For gaming, confirm that the headset’s connection and fit suit the specific device and game.
My Verdict
For children who swim, I would choose Pmjebe Bone Conduction Swimming because its built-in 8GB player and stated submersion capability directly address listening in the pool without relying on a phone connection.
Its 10-hour listed battery life also gives it an edge for longer stretches between charges.
I would choose ZKBSIAXD instead for calls, workouts, and everyday Bluetooth use where its clip-on design and case matter more.
Think about where the headphones will be used most. This is the main dividing line. Pmjebe is the more relevant design for swimming because it lists IP68/IPX8 protection and a built-in MP3 mode. ZKBSIAXD’s IPX4 rating is aimed at sweat and light rain, so it should not be treated as a swimming option. If water use is occasional splashing rather than submersion, the distinction may matter less; for pool use, it matters a great deal.
Separate total battery claims from single-charge playback. Pmjebe lists 10 hours of battery life. ZKBSIAXD lists six hours of continuous playback per charge, with up to 300 hours total when its case is included. Those numbers describe different things, so they are not a direct like-for-like comparison. If you want long listening sessions away from a charging case, Pmjebe’s stated per-charge time is the stronger figure. If you can recharge through the case between sessions, ZKBSIAXD’s total claim may be more useful.
Consider how the headphones connect and control playback. Pmjebe offers Bluetooth and stored MP3 playback, plus push-button controls. ZKBSIAXD relies on Bluetooth and uses touch controls, with call management and voice-assistant functions listed. If the intended listener will use a phone or tablet and take calls, ZKBSIAXD’s controls may fit that routine. If the device needs to stay out of the pool, Pmjebe’s local player is the more important feature.
Be realistic about fit and age. Both products are open-ear designs, but they are not described as the same style. Pmjebe uses a bone-conduction frame; ZKBSIAXD uses a clip-on earbud design. The information provided does not give child-specific dimensions or a child-fit guarantee for either one. A parent choosing between them should focus on the intended activity and check whether the design is comfortable and secure for the particular wearer.
Do not confuse open-ear listening with noise isolation. These designs leave the ears more open than traditional in-ear headphones. Pmjebe emphasizes awareness of surroundings, while ZKBSIAXD lists ENC for calls. That call feature does not turn the earbuds into noise-isolating headphones for music. For environments where the listener needs to hear nearby activity, an open-ear style may be useful; for loud surroundings, neither sheet promises complete isolation.
If price is part of your decision, check the current price on Amazon using the page’s button. I would not let price outweigh the basic fit between product and use: Pmjebe is the swimming and local-playback option, while ZKBSIAXD is the clip-on Bluetooth and call-oriented option.
The product is described for swimming and lists IP68/IPX8 waterproofing, with submersion up to 5 meters for up to 24 hours. Its age-range field says “Adult,” and no child-specific sizing information is provided, so parents should assess fit and suitability.
Its stated water-resistance rating is IPX4, described for sweat and light rain. That is not the same as the submersion specification listed for Pmjebe, so ZKBSIAXD is not the choice here for swimming.
Pmjebe lists 10 hours of battery life. ZKBSIAXD lists up to six hours of playback per charge and up to 300 hours total with its charging case; the total includes case power and is not a single-charge listening figure.
Neither product is described as an in-ear model. Pmjebe is an open-ear bone-conduction headset, and ZKBSIAXD is a clip-on open-ear design. For children who dislike ear-canal pressure, those designs may be worth considering, but the product information does not provide child-specific fit details.
