If you want a dedicated underwater MP3 player that keeps your ears open to the world while you swim or work in wet conditions, choose RELAXYO Bone Conduction Swimming; if you need versatile, lightweight earbuds for general sports and construction sites with a portable charging case, choose SUNGOOOYUE IPX7.
• RELAXYO: Best strength is its professional IPX8 waterproofing and 32GB internal storage for phone-free swimming; biggest trade-off is it cannot transmit audio via Bluetooth while submerged.
• SUNGOOYUE: Best strength is its ergonomic in-ear design and included charging case for extended daily use; biggest trade-off is lower IPX7 water resistance compared to true submersion standards.
• Pick RELAXYO for serious swimmers, pool workouts, or anyone needing bone conduction safety awareness.
• Pick SUNGOOYUE for runners, gym-goers, or those who prefer traditional earbuds with a backup power source.
The RELAXYO Bone Conduction Swimming headphones are built for a very specific type of user: someone who needs to hear their environment while listening to music, especially in wet conditions. The design philosophy here is clearly about safety and immersion. Weighing only 30 grams, this device is engineered to be worn all day without causing fatigue. Unlike conventional in-ear headphones that seal off the ear canal, these use an open-ear bone conduction driver. This means they sit over the ear rather than inside it, keeping the ear canal open to ambient sound. For someone working on a construction site or swimming laps, this feature is not just a gimmick; it is a critical safety mechanism that prevents hearing damage while allowing you to stay aware of surroundings.
The standout feature for any active user is the IPX8 waterproof rating. While many products claim water resistance, this unit is rated to handle full submersion, making it appropriate for swimmers wearing goggles and swim caps. You can work underwater with these, which is a capability most standard earbuds simply do not possess. The inclusion of 32GB of built-in memory transforms how you listen during aquatic activities. Since Bluetooth signals do not travel through water, the device switches to MP3 mode, reading directly from its internal drive. This allows you to load songs from a computer onto the headphones and swim without carrying a phone, eliminating the risk of dropping a device into the pool.

This product is ideal for athletes who prioritize durability and safety over high-fidelity bass. If you are looking for kids headset for construction work where noise isolation might be dangerous, the open-ear design is perfect. However, it is not for everyone. If you require active noise cancelling bone conduction headphones for construction work environments with extreme machinery noise, you might find the open design lets too much external sound in. Furthermore, users who rely heavily on seamless Bluetooth streaming without ever wanting to transfer files via USB will find the reliance on the MP3 mode underwater limiting. It is a specialized tool for water sports and safety-conscious listeners, not a general-purpose audio replacement.
The SUNGOOYUE IPX7 headphones take a different approach, focusing on versatility and convenience for the average active listener. These are traditional in-ear wireless earbuds designed to fit snugly within the ear canal. The material is ABS, providing a sturdy build that feels durable enough for daily wear. The packaging includes two headphones and four cases, suggesting a focus on portability and ease of access. The IPX7 rating indicates they can withstand sweat and rain, making them suitable for fitness and travel. While they may not dive as deep as the RELAXYO, they are more than capable of handling the rigors of a sweaty workout or a sudden downpour during a run.
Battery management is handled differently here. Instead of relying solely on the earbud charge, the design incorporates an 800mAh charging case. This case automatically refills the earbuds when they are placed inside, extending your total listening time well beyond the initial 5-6 hours provided by a single charge. This is a significant advantage for long days on the job or extended commutes where you might not have immediate access to a power outlet. The connectivity technology supports a wide range of devices, including smartphones, tablets, laptops, and other enabled devices. This broad compatibility ensures you can seamlessly switch between work calls on a laptop and music on a phone without pairing issues.
These earbuds are best suited for those who prefer the isolation of an in-ear fit. If you are looking for sports earbuds for construction work that offer a secure fit during heavy movement, the ergonomic design aims to keep them in place comfortably. The efficient technology promises fast and stable connections, ensuring seamless calls and music without interference. However, the trade-off is that they do not offer the same level of environmental awareness as bone conduction models. Users who need to hear traffic, equipment, or colleagues while listening to music might find the in-ear seal isolating. Additionally, without a dedicated MP3 mode, these units likely require a constant Bluetooth connection to a phone or device to function, meaning you cannot listen offline without a paired source.

In my opinion, I would choose the RELAXYO Bone Conduction Swimming if my primary goal was safety and versatility in wet environments, particularly for swimming or construction work where hearing ambient noise is vital. The ability to carry music without a phone and the superior IPX8 waterproofing make it a unique tool that solves specific problems the SUNGOOYUE cannot address. However, if I needed a reliable pair of earbuds for general daily use, gym sessions, or office-to-gym transitions where a charging case is essential, I would opt for the SUNGOOYUE IPX7. For construction work specifically, where safety awareness is non-negotiable, the open-ear design of the RELAXYO offers a distinct advantage that traditional in-ear buds simply cannot match.
Yes, the RELAXYO model is excellent for construction because its open-ear design allows you to hear machinery and voices while listening to music, enhancing safety.
No, the package includes a charging case with an 800mAh capacity that automatically recharges the earbuds, extending usage beyond the 5-6 hour single charge.
While they are IPX7 rated and can handle sweat and rain, they are not designed for full submersion like the IPX8-rated RELAXYO, so swimming is not recommended.
The RELAXYO offers up to 7 hours on a single charge but lacks a case, whereas the SUNGOOYUE provides 5-6 hours per charge but includes a case for multiple additional charges.
