If you want open-ear headphones for small ears that can play music underwater, choose Soveign Waterproof Headphones; if you need lightweight open-ear earbuds for everyday listening, choose TRAUSI IPX7.
The clearest difference is swimming: Soveign has IPX8 protection and built-in MP3 storage, while TRAUSI is an open-ear Bluetooth option with a charging case.
Soveign Waterproof Headphones vs TRAUSI IPX7 at a Glance
• Soveign’s biggest strength: IPX8 protection and 32GB of built-in MP3 storage for listening while swimming. Trade-off: Bluetooth is limited in water, so swimming requires MP3 mode.
• TRAUSI’s biggest strength: Open-ear hook-style buds, Bluetooth 5.4, environmental noise cancellation, and a wireless charging case. Trade-off: Its listed water protection is IPX7, and the product information does not specify built-in music storage.
• Choose Soveign if you want a swimming-focused bone-conduction headset with local music playback.
• Choose TRAUSI if your priority is open-ear listening for walks, everyday routines, and staying aware of your surroundings.
• For small ears: Both use open-ear designs rather than conventional in-ear plugs, but neither sheet gives specific fit measurements or a small-ear fit guarantee.
Soveign is the more purpose-built choice for swimming. It uses a bone-conduction, open-ear design and is listed with IPX8 water protection. The most practical detail is its dual-mode setup: Bluetooth for compatible everyday listening and MP3 playback for time in the water. Bluetooth is limited underwater, so the built-in 32GB memory matters more than the wireless connection when you swim. The product information says the storage can hold more than 6,000 songs, though the actual amount depends on the files.
That combination also gives Soveign a distinct role outside the pool. Its stated uses include activities such as cycling, running, gym sessions, and hiking. Because it sits open rather than plugging the ear canal, it may appeal to someone searching for head phones for small ears who dislikes the feel of conventional earbuds. The frame is described as bendable, and the headset has physical buttons for media, volume, and calls. Those details suggest a design intended to be adjusted and operated without relying only on touch controls.

The main compromise is that the swimming setup is not simply Bluetooth streaming with a stronger waterproof label. You need to use MP3 mode in water, which means loading music onto the headset rather than relying on a connected phone. Soveign’s product information does not list a battery-life figure, Bluetooth range, or fit dimensions, so I would not assume anything about those details. Who should skip it: skip Soveign if you want a conventional pair of Bluetooth earbuds for everyday phone use and do not need built-in music playback for swimming.
TRAUSI is aimed at open-ear listening in everyday settings. Its hook-shaped buds sit around the ear, and its open design is described as keeping the ear canal unblocked so you can hear surrounding sounds while listening. That makes it a sensible option to consider for a walk, a coffee run, or desk work when you do not want fully isolating earbuds. The product information also lists Bluetooth 5.4, touch controls, and a 15-meter Bluetooth range.
The package details include a wireless charging case and a Type-C cable, while the listed average battery life is 50 hours. That figure is a useful point of comparison for someone who wants a setup that can accompany a long day of routine listening. TRAUSI also lists environmental noise cancellation. The product description associates this with calls, but the information does not provide a technical explanation of how it works or promise that outside sound is blocked. Its open-ear design is presented as keeping the world within reach, not shutting it out.
TRAUSI’s big limitation for this comparison is that IPX7 protection is not the same swimming-focused proposition as Soveign’s IPX8 plus MP3 mode. Its data sheet identifies it as waterproof, but does not describe underwater playback or built-in storage for music. The hook shape may work well for some ears, but there are no fit measurements or specific claims for small ears. Who should skip it: skip TRAUSI if swimming with music is your main requirement or you specifically need a headset that can play stored tracks underwater.
• Best fit for swimming-focused use → Soveign Waterproof Headphones. Its IPX8 rating and MP3 mode are the most relevant features here; the instructions specify MP3 playback because Bluetooth is limited in water.
• Best for everyday open-ear Bluetooth listening → TRAUSI IPX7. It lists Bluetooth 5.4, touch controls, and a 15-meter range, making it the more clearly specified pick for routine wireless use.
• Best for built-in music storage → Soveign Waterproof Headphones. The 32GB memory provides a way to listen without a Bluetooth connection.
• Best for a charging-case setup → TRAUSI IPX7. Its package includes a wireless charging case and Type-C cable.
• Best when long listed battery life matters → TRAUSI IPX7. Its product information gives an average battery-life figure of 50 hours; Soveign’s sheet does not provide a comparable figure.
• Best for physical-button operation → Soveign Waterproof Headphones. Its controls include physical buttons for media, volume, and calls. TRAUSI is listed with touch control.
• Best for an around-the-ear hook style → TRAUSI IPX7. Its earpiece shape is listed as a hook, though the product information does not give measurements to predict individual fit.
• Best wireless sports earbuds for small ears? → Neither is guaranteed by the supplied fit details. Both have open-ear designs, but neither sheet confirms a small-ear-specific size or fit. Compare the wearing style you prefer rather than assuming either will fit every ear.
My Verdict
I would choose Soveign if swimming is part of the plan: IPX8 protection and 32GB of MP3 storage give it a specific advantage for listening in water.
If I wanted an everyday open-ear pair instead, I’d lean toward TRAUSI for its hook shape, charging case, Bluetooth 5.4, and stated 50-hour average battery life.
My pick for a swimming-centered routine is Soveign, because its MP3 mode addresses the practical limitation of Bluetooth underwater.
Before choosing, be clear about where you will use the headphones most. A waterproof label by itself does not tell you how music playback works in water. Soveign’s information specifically says Bluetooth is limited underwater and directs swimmers to MP3 mode. If you want to listen to a phone connection while swimming, that distinction matters. If you are not swimming, Soveign’s built-in storage may be less important than comfort, controls, and how you prefer to connect.
Fit is another point to keep grounded in what is actually specified. Both products are open-ear designs, but only TRAUSI has a stated hook-shaped earpiece. Soveign is described as a bendable bone-conduction headset. Neither product sheet supplies ear measurements or confirms suitability for small ears, so the phrase best wireless headphones for small ears cannot be settled by the listed specs alone. Think about whether you prefer a hook around the ear or a flexible band-style bone-conduction design, and check the product’s fit information before deciding.
Finally, compare the features you will use rather than treating the products as interchangeable. TRAUSI gives a specific battery-life figure, a charging case, and Bluetooth details. Soveign gives a clear swimming-use case, MP3 storage, and physical controls, but no battery-life figure in the available information. If price matters to your decision, check the current price on Amazon; the better fit depends on whether you value everyday open-ear convenience or swimming-specific playback more.
The product information says Bluetooth is limited in water and recommends MP3 mode for swimming. Its built-in 32GB storage is intended to let you listen without a Bluetooth connection.
Is TRAUSI IPX7 suitable for swimming?
Neither product sheet gives small-ear measurements or guarantees a small-ear fit. Both use open-ear designs, while TRAUSI is specifically described as hook-shaped and Soveign as a bendable bone-conduction headset, so the wearing style is the clearest distinction.
TRAUSI lists an average battery life of 50 hours. Soveign’s product information does not provide a battery-life figure, so there is no direct comparison available from the listed specifications.
