If you want open-ear wireless bone-conduction headphones for regular workouts and walking, choose Rumatas Swimming Bone Conduction; if you need built-in MP3 storage and IPX8 waterproofing for swimming, choose Soveign Waterproof Headphones. For audiophiles, the practical choice comes down to where you listen: Rumatas keeps the feature set simple, while Soveign offers a dedicated playback mode for time in the water.
Rumatas Swimming Bone Conduction vs Soveign Waterproof Headphones at a Glance
• Rumatas’ biggest strength: an open-ear bone-conduction design, Bluetooth 5.3, and a stated seven-hour battery life. Its trade-off is that the listed specifications do not include built-in music storage or a waterproof rating.
• Choose Rumatas if you want wireless open-ear headphones for walking, workouts, or other everyday activity and value a stated battery figure.
• Choose Soveign if you want to swim with headphones and prefer to carry audio on the device rather than depend on a Bluetooth connection underwater.
Rumatas is an open-ear wireless headset built around a bone-conduction driver. Instead of sitting inside the ear, it uses an ear-hook or wing style of placement, leaving the ear open. That design may suit someone who dislikes having an earpiece inserted during a walk or workout. The available specifications do not establish a particular sound signature or audiophile-grade fidelity, so I would think of it as a practical activity-focused option, not a dedicated listening-room headphone.
Its Bluetooth 5.3 connection has a stated range of 33 feet, and its battery is listed at seven hours with a two-hour charge time. That gives buyers useful planning information: it is intended for wireless use within a typical nearby-device range, and a full charge is not an all-day listening promise. The listed use cases include outdoor activity, walking, and workouts. There is no headphone jack, so wired listening is not an option.
The main caution is swimming. Although the product name includes “Swimming,” the supplied specifications do not state a waterproof rating or describe an MP3 mode. I would not assume it is suitable for use underwater based on the name alone. Skip Rumatas if swimming is your main requirement or you need local music storage.

The dual-mode setup also gives it a different role outside the pool. Bluetooth is available for wireless listening, while MP3 mode plays audio stored on the device. Its stated storage capacity is 32GB, and the product information says that MP3 mode can hold more than 6,000 songs. It also has physical controls for media, volume, and calls, described as operable with one hand. That may appeal to someone who wants buttons rather than relying on touch controls while moving.
Soveign’s product information describes a flexible frame that can bend and be adjusted for comfort. That is a design claim, not a guarantee that it will fit every head or stay equally comfortable in every activity. The supplied details also do not give a battery-life figure, Bluetooth range, or charge time, so there is less information for planning long listening sessions. Skip Soveign if you want a clearly stated battery runtime or expect Bluetooth to work normally underwater.
• Best fit for swimming with stored audio → Soveign Waterproof Headphones. Its IPX8 rating and MP3 mode are the clearest match for underwater listening, with the important caveat that Bluetooth is limited in water.
• Best fit for walking and workouts without an in-ear earpiece → Rumatas Swimming Bone Conduction. Its open-ear placement and bone-conduction driver match the activity-focused use described in its product information.
• Best for a stated battery runtime → Rumatas Swimming Bone Conduction. The listed average battery life is seven hours, and the listed charge time is two hours.
• Best for built-in playback without a phone connection → Soveign Waterproof Headphones. Its 32GB MP3 storage lets you use locally stored audio, including when swimming.
• Best for a stated wireless range → Rumatas Swimming Bone Conduction. Its Bluetooth range is listed as 33 feet. Soveign’s supplied specifications do not give a range figure.
• Best if you want physical media and volume buttons → Soveign Waterproof Headphones. Its control information identifies physical buttons for playback, volume, and calls.
• Best for someone comparing everyday wireless simplicity with swim-specific features → decide by your routine. Rumatas supplies a battery-life figure but no listed waterproof rating; Soveign supplies a waterproof rating and stored audio but no stated runtime.
• Best match for “spatial audio earphones for audiophiles” or “best hifi stereo over ear headphones for audiophiles” searches → neither can be confirmed from these specifications. These are open-ear bone-conduction products, and the available information does not specify spatial audio, stereo performance, or over-ear construction.
My Verdict
Plan around how you listen in water. Soveign’s instructions point swimmers to MP3 mode because Bluetooth is limited underwater. Its storage makes that possible without a phone connection, but it also means choosing and loading audio ahead of time. Rumatas may be convenient for Bluetooth listening during walks or workouts, but the available product details do not establish that it is waterproof. For swimming, that missing information matters more than the product name.
Compare what is stated, not what is assumed. Rumatas provides a seven-hour battery figure, a two-hour charge time, and a 33-foot Bluetooth range. Those figures help set expectations for charging and nearby-device use. Soveign provides a storage capacity and waterproof rating, but no battery runtime or wireless range in the supplied specifications. If session length is important, that gap is worth considering before choosing.
Think about the listening style you want. Both products are open-ear bone-conduction designs, not conventional over-ear headphones. Their stated features are aimed at movement and activity, and neither product’s information specifies sound-stage performance, a frequency range, or spatial-audio support. Someone searching for the best comfortable Bluetooth headphones for audiophiles may find the open-ear approach appealing, but comfort and sound preference remain personal. I would not treat either as a substitute for an over-ear model on the basis of these specifications.
Account for controls and connection needs. Soveign’s physical buttons cover media, volume, and calls, while Rumatas lists a voice controller and wireless controls. The information does not fully describe how every control works in different conditions, so buyers should not assume more than those listed functions. Also note that Rumatas has no headphone jack; both products are described as wireless, and Soveign’s swimming mode relies on stored MP3 audio rather than Bluetooth underwater.
Check the current price on Amazon before deciding. The feature differences are more informative than treating either as an automatic value choice: Rumatas offers stated battery and range figures, while Soveign offers waterproofing and built-in storage. Which set matters more depends on whether your regular listening happens mostly on land or in the water.
The product information says Bluetooth is limited in water and directs swimmers to use MP3 mode. Its built-in 32GB storage is intended to make stored playback possible without relying on an underwater Bluetooth connection.
The available Rumatas specifications do not provide a waterproof rating or swimming-specific playback details. I would not assume it is safe for underwater use based only on the product name.
Rumatas is listed with an average battery life of seven hours and a two-hour charge time. No battery-runtime or charging-time figure is provided for Soveign, so the supplied details do not support a direct battery-life comparison.
Both are open-ear bone-conduction headphones intended for activity-oriented use. Their specifications do not state spatial audio, high-fidelity sound performance, or over-ear construction, so those qualities cannot be confirmed from the available information.
