If you want swimming-focused bone-conduction headphones with a stated 7-hour playtime, choose RELAXYO Bone Conduction Swimming; if you need an extra hour of listed battery life and two-device Bluetooth switching, choose INDIVISO Bone Conduction Headphones. For kids wireless listening, I’d focus first on the swimming mode, fit, and adult supervision—not assume either set is designed specifically for children.
RELAXYO Bone Conduction Swimming vs INDIVISO Bone Conduction Headphones at a Glance
• RELAXYO’s biggest strength: IPX8 protection, 32GB of built-in MP3 storage, and a swimming-oriented design. Trade-off: its listed continuous playtime is 7 hours, one hour less than INDIVISO’s.
• Both use open-ear bone-conduction designs, Bluetooth 5.4, 32GB storage, and IPX8 waterproofing.
• Choose RELAXYO if your routine centers on pool sessions and you want a straightforward MP3 option for underwater listening.
• Choose INDIVISO if you value longer listed battery life and switching between two Bluetooth-connected devices on land.
RELAXYO makes the stronger case for someone whose main reason for buying headphones is swimming. Its IPX8 rating is intended for underwater use, and its 32GB of built-in storage lets you load music from a computer using the included magnetic charging cable. That matters because Bluetooth audio cannot transmit underwater. For a pool session, you need music stored on the headphones and played in MP3 mode rather than a phone connection.
The open-ear bone-conduction design leaves the ear canal uncovered, while the product information gives its weight as 30 grams. That combination may appeal to swimmers who would rather not use conventional in-ear headphones and who want to remain aware of nearby sounds. RELAXYO also lists Bluetooth 5.4 and up to 7 hours of continuous music or phone-call playback when fully charged. Bluetooth is useful outside the water; MP3 mode is the practical choice in it.
I’d consider RELAXYO for a swimmer who wants one device for pool workouts, outdoor exercise, and phone-connected listening on land. I would skip it if an extra hour of stated battery life or the ability to connect to two Bluetooth devices at once is central to the decision. The listed information doesn’t give a two-device switching feature for RELAXYO, so I wouldn’t assume it has one. And although the product is described for adults, its features alone don’t establish that it is specifically sized or designed for children.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

INDIVISO shares the core swimming setup: an open-ear bone-conduction design, IPX8 waterproofing, Bluetooth 5.4, and 32GB of onboard MP3 storage. Its listed water rating specifies immersion up to 3 meters for extended periods. As with RELAXYO, that water resistance doesn’t make Bluetooth work underwater. The practical routine remains the same: use Bluetooth for a compatible device on land, and switch to MP3 mode when swimming.
The product information describes a lightweight, ergonomic fit intended to stay in place during active movement, and specifies an open-ear hook enclosure. That could be useful for running, cycling, or training, where an earbud that seals the ear may not be your preference. I’d look elsewhere if your deciding factor is a specifically child-oriented fit: the available details describe an adult age range, not a dedicated kids’ fit. Also, the listed battery figure is a specification, not a guarantee of identical runtime in every use.
• Best fit for a swimming-first routine → RELAXYO Bone Conduction Swimming. It is explicitly positioned for swimming and pairs IPX8 protection with MP3 playback for underwater use.
• Best for longer listed playtime → INDIVISO Bone Conduction Headphones. Its stated maximum is 8 hours, compared with RELAXYO’s 7 hours.
• Best for two-device Bluetooth switching → INDIVISO. It lists simultaneous connection to two devices. Bluetooth remains a land-use feature; neither model streams Bluetooth audio underwater.
• Best for loading music directly onto the headphones → Tie. Both offer 32GB of built-in storage and MP3 mode, so either can play stored audio without a phone during a swim.
• Best for Bluetooth 5.4 on land → Tie. Both list Bluetooth 5.4. INDIVISO additionally specifies a range of up to 33 feet.
• Best for a buyer who wants a stated immersion depth → INDIVISO. Its product details specify up to 3 meters; RELAXYO lists IPX8 without a depth figure in the provided information.
• Best for kids wireless listening → Neither is an obvious child-specific pick from the listed details. Both are described for adults, so check fit and supervision needs rather than treating either as a kids’ model.
• Best for comparing a work-and-study headset with an open-ear sports model → INDIVISO has the more clearly specified device-switching feature. But shoppers looking for with mic on ear headphones for college students or with microphone in ear headphones for streaming should note that neither sheet gives microphone placement or streaming-focused call performance.
The phrase best sweatproof open ear earbuds can also point shoppers toward a different kind of product. These are open-ear bone-conduction headphones with IPX8 protection, not conventional in-ear earbuds. Both are described for exercise and water exposure, but neither product sheet supplies a sweat-specific testing standard beyond the stated waterproof rating. If sweat resistance is your main concern, read the product’s precise water-protection details and choose based on your activity rather than assuming all open-ear designs are interchangeable.
The distinction between the two models is less about their basic concept than about the details around it. Both offer stored playback for swimming and Bluetooth playback for land use. Both leave the ear canal open, and both use the same listed Bluetooth version and storage capacity. That makes the decision fairly focused: choose RELAXYO for its swimming-oriented presentation, or INDIVISO for its additional listed runtime and two-device connection feature.
There are also a few details neither product sheet settles. Neither gives a frequency response for INDIVISO, and neither provides enough information to compare actual sound quality directly. RELAXYO lists a frequency range, but that alone doesn’t establish how music will sound to an individual listener. Likewise, the stated waterproof ratings and battery figures are useful specifications, but they do not tell us how a particular person will experience fit, comfort, or runtime.
In my opinion, I’d buy RELAXYO Bone Conduction Swimming if my main goal were pool listening: its IPX8 design and onboard MP3 mode make the underwater use case easy to understand. For kids wireless listening, I would still check fit carefully and keep the headphones within an adult-supervised routine, since the product details describe an adult age range. I’d pick INDIVISO instead if I valued its extra listed hour of battery life and two-device switching more than a swimming-first emphasis.
No. Both product sheets state that Bluetooth signals cannot transmit underwater. Load audio onto the built-in 32GB storage and use MP3 mode for swimming; use Bluetooth when listening on land.
INDIVISO lists up to 8 hours of continuous music or talk time. RELAXYO lists up to 7 hours. Actual runtime can vary with use, so treat these as stated maximums rather than a promise for every session.
Are RELAXYO and INDIVISO suitable for kids?
Either could suit someone who wants an open-ear bone-conduction design for outdoor exercise. INDIVISO lists two-device Bluetooth connection and up to 8 hours of playback; RELAXYO lists Bluetooth 5.4 and up to 7 hours. Neither spec sheet establishes which will feel more comfortable to a particular wearer.
