If you want bone conduction headphones for video calls with offline MP3 storage, a quick-charge option, and swimming-focused water protection, choose mojawa Run Plus Bone; if you need longer stated battery life, newer Bluetooth, and straightforward physical controls, choose KIM HOST Bone Conduction Headphones. For calls at a desk or on the move, both leave your ears open, but their feature priorities differ.
mojawa Run Plus Bone vs KIM HOST Bone Conduction Headphones at a Glance
• KIM HOST Bone Conduction Headphones: Its biggest strength is up to 11 hours of playtime with Bluetooth 5.3 and physical controls. Its trade-off is that its sheet does not specify offline-storage capacity or a quick-charge feature.
• For swimming and offline listening: mojawa is the more fully specified fit, with 32GB storage and detailed submersion guidance.
• For longer stretches between charges: KIM HOST has the longer stated playtime, while still offering an open-ear design and call controls.
• Choose mojawa for: workouts, water use, and flexibility between Bluetooth and stored audio.
• Choose KIM HOST for: everyday wireless calls, simple button operation, and a longer stated battery run.
• Both are open-ear bone conduction models, so neither is designed to seal off the ear canal. That can suit someone who wants to hear nearby sounds while listening, although neither product lists noise control. For video calls, the practical distinction is less about a claimed call-quality winner and more about how you plan to connect, operate, and recharge the headset.
The Run Plus is the more versatile choice for someone who wants one headset for a workout, a swim, and everyday listening. Its open-ear fit keeps the ear canals uncovered, and the around-ear design is described as compatible with helmets and glasses. That combination may be useful for cycling or running where you want to remain aware of surrounding sounds without removing your headphones. It is also a bud-free option for work or daily use.
Its 32GB built-in MP3 player gives you an offline listening option as well as Bluetooth 5.2. The product information says that capacity can hold up to 8,000 songs or audiobooks. This is a meaningful distinction for swimming: the instructions call for disconnecting Bluetooth, switching to MP3 mode, and disabling the touchpad before getting in the water. Its IP68 rating is specified for submersion up to two meters for up to two hours. After saltwater exposure, the guidance is to rinse it with fresh water.

KIM HOST is aimed at listeners who want an open-ear headset with uncomplicated physical controls and a longer stated run time. Its Bluetooth version is 5.3, and the product description claims a stable connection in crowded signal environments. It lists compatibility with smartphones, laptops, tablets, Android, iOS, PC, and Mac, so it can fit a mixed-device routine that includes calls on a computer and audio from a phone.
The physical buttons are described as handling playback, track skipping, volume, and calls. That makes the controls easy to understand on paper, particularly if you prefer buttons to touch-sensitive operation while walking or exercising. The headset is also described as flexible, with skin-friendly materials and an ergonomic open-ear fit. Those details point toward a model for everyday wear, work, running, cycling, or swimming, while leaving the ears uncovered for awareness of nearby sounds.
KIM HOST states up to 11 hours of continuous use and a one-hour charge time. That is the longer stated battery figure in this comparison, though it is a manufacturer specification rather than a guarantee of identical results for every listening pattern. It also does not list built-in MP3 storage capacity, so buyers who want music saved directly on the headset should not assume that option is equivalent. Skip it if offline playback details and a clearly specified quick-charge feature are important to you.
• Best fit for a swim with offline music → mojawa Run Plus Bone. Its 32GB MP3 mode is specifically relevant when Bluetooth is disconnected for swimming, and its submersion guidance gives a depth and duration.
• Best for longer stated playtime → KIM HOST Bone Conduction Headphones. It claims up to 11 hours, compared with mojawa’s up to eight hours at 75% volume.
• Best for a quick top-up → mojawa Run Plus Bone. A five-minute charge is specified to provide 80 minutes of playback; KIM HOST lists a one-hour charge time but no quick-charge figure.
• Best for physical controls during calls → KIM HOST Bone Conduction Headphones. Its buttons are described for answering calls and adjusting audio, with a control method based on push buttons.
• Best for someone considering bone conduction headphones for video calls and noisy surroundings → mojawa Run Plus Bone. Its sheet specifically describes ENC noise reduction for calls and dual microphones for voice pickup. That is a feature distinction, not a measured call-quality comparison.
• Best for a newer listed Bluetooth version → KIM HOST Bone Conduction Headphones. It specifies Bluetooth 5.3, while mojawa lists Bluetooth 5.2.
• Best for a stated fit with helmets and glasses → mojawa Run Plus Bone. Its product information explicitly describes that use; KIM HOST’s sheet does not make the same fit claim.
• Best for a clearly described flexible use pattern → mojawa Run Plus Bone. Bluetooth and MP3 modes let you switch between a connected device and stored audio, while KIM HOST’s listed strengths center on Bluetooth use and physical controls.
For ordinary office calls, both models offer a wireless, open-ear format, but the available specifications do not establish which one sounds clearer in every room or with every computer. If you often move between devices, KIM HOST’s stated compatibility is broad. If you need to leave your phone behind during a swim or want an offline option for a workout, mojawa provides the more explicit storage details.
Buying Considerations
Think about where you will wear the headphones most often before focusing on a single spec. For swimming, the key difference is not simply that both sheets mention IP68. mojawa gives a specific submersion limit and instructions to switch to MP3 mode, disconnect Bluetooth, and disable the touchpad. KIM HOST lists IP68 waterproofing but does not provide a comparable depth-and-time description in its sheet. If detailed water-use guidance matters, that makes mojawa easier to assess from the information available.
For video calls at a desk, consider both the microphone claims and how you prefer to control calls. mojawa explicitly describes ENC and dual microphones, while KIM HOST explicitly describes physical buttons for calls. Neither sheet provides a microphone test, a call-noise measurement, or a quantified sound comparison, so those features should guide your expectations without being treated as proof that one will sound better in every setting. A touch control headphone for video calls may sound convenient, but mojawa’s listed control type is button control; check the control details rather than assuming a touch interface.
The battery figures also need context. KIM HOST lists up to 11 hours and a one-hour charge. mojawa lists up to eight hours at 75% volume, plus a short-charge benefit. If you usually recharge overnight, the longer KIM HOST figure may matter more. If your routine includes hurried top-ups before a workout, mojawa’s stated five-minute charge could be more relevant.
Finally, neither is a memory foam ear cushions wireless headphones for video calls. Both use an open-ear bone conduction design, rather than the cushioned, ear-covering style implied by that search phrase. The choice here is between two open-ear options: prioritize mojawa’s specified offline storage and water-use detail, or KIM HOST’s longer stated playtime, Bluetooth 5.3, and physical buttons. If the purchase decision depends on current price, check the current price on Amazon using the page’s button; I can’t make a price-based value comparison from these product details.
I would choose mojawa Run Plus Bone for its 32GB MP3 mode, detailed swimming guidance, and fast-charge option.
For video calls, its listed ENC and dual microphones also give me more specific call-related features to weigh.
KIM HOST is the better fit if I valued longer stated battery life and physical buttons above offline storage.
But for one open-ear headset spanning calls, workouts, and swimming, mojawa is my pick.
mojawa specifically lists ENC intended to reduce background noise during calls and dual microphones for voice pickup. KIM HOST lists Bluetooth compatibility and physical call controls, but does not specify the same microphone features.
Both product sheets describe IP68 waterproofing. mojawa gives a submersion limit of up to two meters for up to two hours and advises switching to MP3 mode before swimming; KIM HOST does not provide matching depth-and-duration details in its sheet.
KIM HOST states up to 11 hours of continuous use. mojawa states up to eight hours at 75% volume, but also specifies a five-minute charge that adds 80 minutes of playback.
No such cushions are listed for either model. Both are described as open-ear bone conduction headphones, so shoppers seeking cushioned over-ear headphones should look for a different design.
