MOSSANTFUL Bone Conduction Headphones•Workout vs TRAUSI IPX7 at a Glance
• MOSSANTFUL’s biggest strength: Bone-conduction audio, open-ear wear, IPX8 water resistance, and built-in MP3 storage make it the more swimming-focused option. Its trade-off is that Bluetooth is restricted in water, so underwater listening requires MP3 mode.
• TRAUSI’s biggest strength: Open-ear hook-style earbuds, Bluetooth 5.4, a stated 15-meter Bluetooth range, touch controls, and a charging case make it a practical everyday wireless option. Its trade-off is that its IPX7 rating and listed features do not establish the same swim-focused MP3 setup as the MOSSANTFUL.
• Choose MOSSANTFUL for swimming, onboard music, and bone-conduction design; choose TRAUSI for Bluetooth listening during walks, commutes, and everyday tasks.
The MOSSANTFUL is the more specialized choice. Its open-ear bone-conduction design sends sound through vibration rather than covering the ear canal, and its IPX8 rating is specified for submersion up to 3 meters for as long as 30 minutes. That gives it a concrete role for swim workouts, where an ordinary Bluetooth connection is not a reliable way to listen underwater.
The crucial detail is the playback mode: Bluetooth is restricted in water, so the headphones need to be in MP3 mode for swimming. The product information describes built-in storage inconsistently, with the title naming 32GB and a feature listing 16GB. I would not assume a specific capacity without confirming it in the product details. Either way, the stated design includes onboard MP3 playback, so swimming does not have to depend on a phone connection.
The flexible silicone construction is described as bendable through 360 degrees, with a fit intended to stay secure during water activities. I would consider the MOSSANTFUL for a child who swims and wants music without blocking the ear canal, while checking the fit carefully for that child. I would skip it if the main goal is conventional Bluetooth listening underwater, or if the child primarily wants a gaming headset with features such as a boom microphone or spatial audio. Those capabilities are not listed here.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The TRAUSI is an open-ear Bluetooth earbud set aimed at everyday listening rather than a clearly documented swimming routine. Its hook-style earpieces leave the ear canal open, and its listed Bluetooth 5.4 connection, 15-meter range, touch controls, and charging case describe a wireless setup for activities such as walking, errands, or listening while working. The product information also lists environmental noise cancellation, but it does not explain how that feature works or establish that it blocks outside sound.
Its IPX7 label makes water resistance part of the design, but the supplied information does not specify submersion depth or duration. Nor does it list onboard MP3 storage or a swimming-specific playback mode. That matters: a water-resistance rating alone does not tell me that a set is designed for listening underwater. For pool use, the MOSSANTFUL has more directly relevant details.
The TRAUSI may suit a child or adult who wants open-ear earbuds for dry-land listening and prefers touch controls and a charging case. The stated battery life is 50 hours, though the product information does not clarify the conditions or what role the case plays in that figure. I would not choose it as a gaming headset or assume it offers spatial audio: neither is specified. For anyone searching for the best over ear headphones for children, it is also worth noting that both of these products are open-ear designs, not conventional over-ear headphones.
• Best for swimming with stored music → MOSSANTFUL Bone Conduction Headphones•Workout. It has IPX8 protection with a stated submersion limit and onboard MP3 playback. Use MP3 mode in water; Bluetooth is restricted there.
• Best for ordinary Bluetooth listening on dry land → TRAUSI IPX7. Bluetooth 5.4 and a stated 15-meter range make its wireless connection the more clearly specified choice for everyday use away from the pool.
• Best for bone-conduction design → MOSSANTFUL Bone Conduction Headphones•Workout. Its sound is conducted through vibration, and its open-ear form leaves the ear canal unobstructed.
• Best for hook-style earbuds and touch control → TRAUSI IPX7. The earpiece shape is listed as a hook, and its controls are touch-based.
• Best for a swim-specific water-resistance description → MOSSANTFUL Bone Conduction Headphones•Workout. Its information gives both depth and duration for submersion; the TRAUSI details provide an IPX7 rating without those specifics.
• Best for a stated long battery figure → TRAUSI IPX7. Its listed average battery life is 50 hours. The MOSSANTFUL information does not provide a battery-life figure, so there is no direct comparison on that point.
• Best for a child who wants a gaming headset → Neither based on the listed features. Neither product description establishes a boom microphone, gaming compatibility, or spatial audio. The phrase “best noise canceling gaming headset for children” points to a different category than either of these open-ear options.
• Best for choosing between these two for a child who swims → MOSSANTFUL Bone Conduction Headphones•Workout. Its MP3 playback and more detailed submersion information make the use case clearer, though fit and suitability should be checked for the individual child.
The biggest practical difference is not simply the water-resistance label. It is what the headphones are designed to do when a phone signal cannot reach them. The MOSSANTFUL lists MP3 playback from built-in storage and specifically says to use that mode while swimming. The TRAUSI lists Bluetooth features and a charging case, but its supplied details do not describe stored music. For laps or underwater practice, that distinction matters more than a small difference in Bluetooth version.
For a child, I would make the choice around the activity rather than a broad label like “kids’ headphones.” A child who swims and wants music during pool workouts has a specific reason to consider the MOSSANTFUL. A child who listens while walking, doing homework, or moving around on dry land may find the TRAUSI’s Bluetooth format and touch controls more relevant. The listed age descriptions are adult for the MOSSANTFUL and adult/youth for the TRAUSI, but those labels do not establish that either model will fit every child comfortably.
There is also a useful limit to keep in mind when comparing them. “Open ear” may help a listener remain more aware of nearby sounds, but it does not mean every sound will be easy to hear in every setting. Neither set is described as a dedicated spatial-audio product, and neither is specified as a gaming headset. If a child needs a microphone for voice chat, a gaming connection, or a particular surround-sound feature, I would look for those capabilities explicitly rather than infer them from the open-ear design.
My Verdict
For a child who swims, I would choose the MOSSANTFUL because it pairs a defined submersion rating with onboard MP3 playback and a bone-conduction open-ear design. The need to use MP3 mode in water is a real limitation, not a footnote, but it also makes the intended use clear. I would choose the TRAUSI for everyday Bluetooth listening on dry land, especially if its hook-style fit, touch controls, and charging case are a better match. My pick for the swimming-focused child is MOSSANTFUL.
FAQ
Can I use the MOSSANTFUL Bone Conduction Headphones•Workout over Bluetooth while swimming?
Is the TRAUSI IPX7 suitable for swimming?
It has an IPX7 waterproof rating, but the supplied details do not give a submersion depth or duration or describe underwater playback. They also do not list onboard MP3 storage. I would not assume that the TRAUSI is a swim-listening substitute for the MOSSANTFUL based on the rating alone.
For dry-land Bluetooth listening, the TRAUSI has a listed Bluetooth 5.4 connection, touch controls, hook-style earpieces, and a charging case. For a child who swims and wants stored music, the MOSSANTFUL has the more relevant features. Fit is individual, so check how the open-ear design sits on the child before settling on either.
Neither product’s supplied features specify spatial audio. They are both open-ear designs, but that does not establish spatial-audio support. If that feature is essential, look for a product that explicitly lists it rather than assuming it is included here.
