If you want immersive bass and a secure seal for high-intensity movement, choose SUNGOOYUE Earbuds Earbuds Heavy; if you need situational awareness and true waterproofing for aquatic environments, choose RELAXYO Bone Conduction Swimming. This isn't a subtle debate between two similar gadgets; it is a choice between two fundamentally different approaches to audio delivery that serve distinct purposes in the field.
• SUNGOOYUE Earbuds Earbuds Heavy: Delivers deep bass and active isolation with a 5-to-6-hour battery life, but lacks underwater capability and relies on Bluetooth which fails submerged. Best for runners, gym-goers, and hunters who need sound isolation.
• RELAXYO Bone Conduction Swimming: Offers open-ear safety, IPX8 waterproofing for full submersion, and built-in 32GB storage for phone-free listening, but sacrifices bass depth and cannot use Bluetooth underwater. Best for swimmers, outdoor athletes, and hunters needing environmental awareness.
The SUNGOOYUE Earbuds Earbuds Heavy are engineered for people who demand a traditional stereo experience where the music dominates the environment. The design centers around an in-ear form factor supported by four replacement earplugs, ensuring that users can find a customized fit that seals tightly against the ear canal. This physical seal is what allows the unit to deliver its heavy bass profile, creating an immersive soundscape that drowns out wind noise or background chatter. For anyone who listens to podcasts or music while running on a trail or working out in a noisy gym, this product offers a level of acoustic isolation that open-ear designs simply cannot match.
The build quality focuses heavily on durability during intense physical activity. With an IPX7 rating, these earbuds are sweat and rainproof, making them suitable for rigorous workouts where perspiration is a constant threat. They utilize Bluetooth 5.3 technology, which provides a stable connection up to 10 meters away from the source device. This range is sufficient for most scenarios where the user might move around a room or a small yard without losing the signal. The charging case houses a 200mAh battery, which extends the total usage time significantly beyond the single charge capacity of the buds themselves. On a single charge, the earbuds offer 5 to 6 hours of continuous playback, a figure that aligns well with standard workout sessions or long commutes.
However, this product is not without limitations. The reliance on a physical seal means that wearing them for extended periods might feel intrusive to some users who prefer an open-air feeling. Furthermore, because they are in-ear devices, they do not allow the wearer to hear ambient sounds like approaching traffic, wildlife, or other people. While this isolation is a feature for focus, it becomes a safety hazard in specific environments. The design is also strictly land-based; while water-resistant, they are not rated for submersion. If you plan to wear them in the rain, they will hold up, but dropping them in a pool or lake would likely result in damage. They are ideal for those who prioritize audio fidelity and battery convenience over total environmental awareness.

The RELAXYO Bone Conduction Swimming headphones take a radically different approach by bypassing the ear canal entirely. Instead of pushing sound waves into your ear, these units vibrate against the cheekbones to transmit audio directly to the inner ear. This "open-ear" design is the defining characteristic of the product, allowing users to remain fully aware of their surroundings at all times. For a hunter using clip on earbuds for hunting, this feature is critical. You can listen to your playlist or podcast while still hearing the crunch of leaves underfoot, the call of a bird, or the rustle of a predator moving nearby. The device weighs only 30 grams, making it exceptionally lightweight and comfortable enough to wear all day without causing fatigue or pressure points inside the ear.
Water resistance is where this product truly separates itself from the competition. With an IPX8 rating, these headphones are designed to be worked underwater. Unlike standard water-resistant electronics that merely repel splashes, the RELAXYO unit can handle full submersion, making it the perfect companion for swimming laps, diving, or even just getting caught in a torrential downpour. It accommodates both goggles and swim caps comfortably. Crucially, it includes 32GB of built-in memory, turning the headphones into a standalone MP3 player. This means you do not need to carry your smartphone with you. You can load songs onto the device via a computer and swim freely without worrying about a phone breaking or a Bluetooth connection failing beneath the surface. Note that Bluetooth transmission does not work underwater, so the internal storage mode is required for aquatic use.
The trade-off for this versatility is the nature of the audio output. Bone conduction drivers generally cannot reproduce the same low-frequency bass response as traditional dynamic drivers. The sound is clear and crisp, but it lacks the thumping depth that audiophiles or bass lovers expect. Additionally, the battery life is capped at 7 hours of continuous play or calls, which is solid but slightly less than the combined potential of the SUNGOOYUE system when counting the charging case. The device uses Bluetooth 5.4, offering improved speed and stability over previous generations, but again, this wireless link is useless once you go below the water line. This product is for the person who values safety and versatility above absolute sonic perfection, particularly in wet or dangerous environments.
• Best for immersion and bass → SUNGOOYUE Earbuds Earbuds Heavy (sealed design blocks outside noise).
• Best for situational awareness → RELAXYO Bone Conduction Swimming (open-ear design keeps ears free).
• Best for swimming and submersion → RELAXYO Bone Conduction Swimming (IPX8 rated, works underwater).
• Best for battery flexibility → SUNGOOYUE Earbuds Earbuds Heavy (includes charging case for extended use).
• Best for phone-free workouts → RELAXYO Bone Conduction Swimming (built-in 32GB storage).
• Best for rugged rain/sweat → Both are excellent, but SUNGOOYUE is IPX7 while RELAXYO is IPX8.
• Best for over ear headphones for hunting → RELAXYO Bone Conduction Swimming (allows hearing game movements).
• Best for secure fit during running → SUNGOOYUE Earbuds Earbuds Heavy (multiple earplug sizes ensure tight seal).
In my opinion, I would choose the RELAXYO Bone Conduction Swimming for almost any outdoor application, including hunting. The ability to stay aware of your environment while listening to audio is a non-negotiable safety feature that outweighs the lack of deep bass. When you are out in the woods or near water, knowing what is happening around you is far more valuable than perfect sound isolation. The built-in storage also removes the tether to a phone, reducing clutter and risk of loss. However, if your primary goal is pure musical enjoyment in a controlled environment like a home gym or a quiet run, the SUNGOOYUE Earbuds Earbuds Heavy provide a superior listening experience with their sealed bass design. For the specific intent of hunting, where hearing the forest is as important as hearing the music, the bone conduction model is the clear winner.
Yes, they are often better than in-ear options because they allow you to hear ambient sounds like animal calls or footsteps while still enjoying audio.
No, the RELAXYO unit comes with 32GB of built-in memory, so you can load music directly from a computer and use it without a phone.
No, the SUNGOOYUE model is IPX7 rated, meaning it handles sweat and rain, but it is not designed for full submersion like the IPX8 RELAXYO unit.
The RELAXYO offers 7 hours on a single charge, while the SUNGOOYUE offers 5 to 6 hours per charge, though the SUNGOOYUE includes a charging case for extra power.
