If you want more onboard storage and Bluetooth 5.3, choose Soveign Waterproof Headphones; if you need a clearly stated submersion limit and an open-ear design, choose MOSSANTFUL Swimming Headphones. For airplane travel, either can play audio from its built-in MP3 storage without relying on a phone connection, though neither product’s listed features include active noise cancellation.
Soveign Waterproof Headphones vs MOSSANTFUL Swimming Headphones at a Glance
• MOSSANTFUL’s biggest strength: IPX8 waterproofing with a stated limit of up to 3 meters for 30 minutes. Trade-off: Its built-in storage is 16GB, half of Soveign’s.
• Both use a bone-conduction, open-ear design, have flexible frames described as bendable through 360 degrees, and support MP3 playback for swimming.
• Choose Soveign if extra offline storage and the newer listed Bluetooth version matter most.
• Choose MOSSANTFUL if you want a stated water-depth and time limit to guide your swimming use.
Soveign’s clearest advantage is its 32GB of built-in memory. That gives you more room for music or other MP3 audio than MOSSANTFUL’s 16GB, and the product description says the storage can hold more than 6,000 songs. The key practical point is that you can use MP3 mode without carrying a phone or maintaining a Bluetooth connection.
That offline mode is especially relevant in the pool. Soveign specifically notes that Bluetooth is limited underwater and recommends MP3 mode when swimming. Its IPX8 rating is presented as suitable for swimming and diving, but the available product details do not give a specific depth or duration. If you want a precise immersion limit, MOSSANTFUL provides more concrete guidance.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The flexible bone-conduction frame and physical controls may appeal if you want an open-ear headphone with buttons for functions such as volume and calls. I’d consider Soveign for swimmers who want more built-in audio storage, or for travelers who would rather bring downloaded MP3s than depend on a wireless connection. I’d skip it if your decision depends on a stated water-depth limit, or if you need confirmed battery runtime: no battery-life figure is provided.
MOSSANTFUL Swimming Headphones: Who It's For
MOSSANTFUL makes its water-use limit more specific: the product is described as IPX8-rated for submersion up to 3 meters for up to 30 minutes. That doesn’t establish how every swimming situation will go, but it gives shoppers a concrete specification to compare against their intended use. Like Soveign, it recommends MP3 mode for swimming because Bluetooth is restricted in water.
Its open-ear bone-conduction design leaves the ear canal unblocked, while the built-in 16GB memory lets you listen without bringing a phone into the pool. The frame is described as soft silicone and bendable through 360 degrees. Those features make the design a plausible fit for people who want an adjustable, phone-free setup for swimming and other exercise.
MOSSANTFUL may suit you if the stated submersion limit matters more than maximizing storage. Bluetooth 5.0 is listed for use with compatible devices outside the water, but don’t treat that as a way to stream reliably underwater. I’d look elsewhere if you want more than 16GB of onboard storage or need a confirmed battery runtime; the listed information gives no battery-life figure.
• Best for more onboard MP3 storage → Soveign Waterproof Headphones. It has 32GB, compared with MOSSANTFUL’s 16GB. That difference matters most if you want a larger offline library.
• Best for a stated submersion limit → MOSSANTFUL Swimming Headphones. Its product details specify up to 3 meters for 30 minutes; Soveign’s do not state a depth or duration.
• Best for the newer listed Bluetooth version → Soveign Waterproof Headphones. It lists Bluetooth 5.3, while MOSSANTFUL lists Bluetooth 5.0. This comparison does not establish a real-world range or connection advantage.
• Best for swimming without a phone → Either, using MP3 mode. Both have built-in storage and say Bluetooth is restricted in water. Soveign offers more space; MOSSANTFUL provides the clearer immersion limit.
• Best for an open-ear fit → Either. Both are described as bone-conduction, open-ear designs. MOSSANTFUL specifically says the ear canal remains unblocked.
• Best for button-based control details → Soveign. Its listed controls include physical buttons, volume controls, and call-answering controls. MOSSANTFUL’s supplied details identify media control without spelling out the same button layout.
• Best for airplane travel → A close call. Either can store MP3 audio for offline listening, but neither lists active noise cancellation or an airplane-specific feature. Soveign has more storage; MOSSANTFUL has the more precise water-use specification.
• Best if you’re searching for rechargeable gaming headphones with charging case → Neither based on the listed features. These are bone-conduction swimming headphones, and neither product’s details specify a charging case or gaming-focused features.
A couple of common searches can also lead shoppers toward the wrong category. “Under 20 in ear headphones” suggests a price and an in-ear fit, but these products’ prices aren’t assessed here and both are open-ear bone-conduction designs. Likewise, “headband headphones for small ears” describes a fit concern, but neither listing provides small-ear sizing or a headband size measurement. The flexible frame may be relevant to fit, but it isn’t enough to confirm how either will fit a particular person.
For flights, the distinction is simple but important: offline playback can be useful when you don’t want to rely on a Bluetooth connection, while an open-ear design does not itself block cabin noise. If you want to judge whether either is suitable for your travel setup, check the product information for details that matter to you, including battery runtime and how the headphones are charged; those specifications aren’t provided here.
I’d choose Soveign Waterproof Headphones if I wanted one of these for airplane travel and swimming, mainly because its 32GB storage gives me more room for offline MP3 audio, and it lists Bluetooth 5.3. I would still use MP3 mode in the water. If a clearly stated submersion limit matters more to you than extra storage, I’d choose MOSSANTFUL instead.
Both products warn that Bluetooth is restricted in water and direct swimmers to MP3 mode. For underwater listening, plan to use audio stored on the headphones rather than relying on a phone connection.
Soveign has 32GB of built-in memory, while MOSSANTFUL has 16GB. Both support MP3 playback, so either can be used for stored audio without bringing a phone into the pool.
Neither lists active noise cancellation or an airplane-specific feature. Both offer built-in MP3 storage for offline listening; Soveign holds more, while MOSSANTFUL has less storage but gives a stated submersion limit.
MOSSANTFUL states a limit of up to 3 meters for 30 minutes under its IPX8 description.
