If you want a lightweight, ergonomic bone conduction headset optimized for open-ear safety and long-duration swimming with zero-delay Bluetooth 6.0 connectivity, choose Rhyfell Bone Conduction Swimming; if you need a rugged, over-ear design with broad file format support and a slightly more traditional button layout for multi-sport versatility, choose SAMVEK Swimming Headphones.
• Rhyfell Bone Conduction Swimming: Its biggest strength is the ultra-lightweight 28g frame designed specifically for swimmers, combined with Bluetooth 6.0 for instant pairing; its trade-off is the specific focus on the open-ear fit which may not suit those who prefer an over-ear clamping style. This pick is for serious athletes and parents looking for a kids headset for remote work or sports that prioritizes comfort during extended wear.
• SAMVEK Swimming Headphones: Its biggest strength is the robust IP68 rating paired with a versatile 32GB storage system supporting multiple audio formats like FLAC and APE; its trade-off is the slightly heavier 30g build and an over-ear style that might feel less "invisible" than the Rhyfell model. This pick is for users who want a durable, all-in-one MP3 player for cycling, fishing, and travel without worrying about phone proximity.
The Rhyfell Fit 5 stands out immediately because of its engineering philosophy: it was built from the ground up to be invisible while in use. At just 28 grams, it leverages liquid silicone materials to create an ergonomic shape that hugs the cheekbones rather than clamping down on the ears. This is not just a marketing claim; it translates to a physical reality where the device feels like an extension of your head rather than an accessory strapped to it. For anyone who has ever struggled with heavy headphones slipping off during a vigorous lap swim or causing ear fatigue after an hour of hiking, this weight difference is transformative. The open-ear design allows sound to transmit through your cheekbones, keeping your ear canals completely clear. This is critical for situational awareness, whether you are swimming in a busy pool, surfing in the ocean, or running near traffic. You remain aware of your environment while still enjoying your playlist.
The battery life on the Rhyfell is another compelling factor for the dedicated athlete. With a claimed 10 hours of continuous playtime, it effectively doubles the industry standard of five hours found in many competitors. This means you can go from sunrise marathons to sunset hikes without needing to stop and recharge mid-session. The inclusion of Bluetooth 6.0 further cements its position as a high-performance device for active users. It promises zero-delay pairing and a stable connection within a 10-meter range, ensuring that your music never skips when you move quickly. Whether you are doing triathlon training or just a casual jog, the stability of the signal is paramount.

However, this product is not for everyone. If you are someone who prefers the isolation of an over-ear cup or relies heavily on deep bass response that requires physical blockage of the ear canal, the open-ear nature of the Rhyfell might feel thin. Additionally, while the 32GB storage allows for over 8,000 songs, the device is marketed heavily toward the active demographic. It is less ideal for the casual listener who wants a simple, static device and more ideal for the user who needs a reliable companion for dynamic movement. If you are a parent searching for a kids headset for remote work or a child engaging in sports, the secure, non-intrusive fit makes it a strong candidate, provided the child is comfortable with the sensation of bone conduction.
The SAMVEK X7 takes a different approach, leaning into durability and versatility across a wider range of environments. While it shares the core IP68 waterproof rating that allows for full submersion up to two meters, its design language is distinct. Weighing 30 grams, it is only marginally heavier than the Rhyfell, but the construction material—Acrylonitrile Butadiene Styrene (ABS)—suggests a hardier shell designed to withstand the rigors of various activities beyond just swimming. It features an over-ear style, which provides a different kind of stability and potentially a more secure fit for those with larger heads or those who prefer a classic headphone silhouette. This form factor is particularly useful for activities like cycling or boating where wind resistance might be a concern, offering a slight edge in protection compared to the open-fit alternative.
One of the most significant advantages of the SAMVEK is its file format flexibility. It supports MP3, WMA, WAV, APE, and FLAC formats natively. For audiophiles or users who have large libraries of high-resolution audio files, the ability to drag and drop these directly onto the device via a magnetic charging cable is a major convenience. The 32GB internal memory holds up to 8,000 songs, matching the capacity of the Rhyfell, but the broader codec support ensures that you aren't limited to compressed formats. The battery life here is rated at 8 hours, which is substantial and sufficient for most daily workouts or long travel days, even if it falls slightly short of the Rhyfell's 10-hour claim.
The control scheme on the SAMVEK is straightforward, utilizing multi-function buttons to manage playback, calls, and mode switching. This tactile approach appeals to users who want physical feedback without relying on touch sensors, which can sometimes be finicky when wet or gloved. The Bluetooth 5.4 technology offers a stable connection up to 10 meters, compatible with both iOS and Android devices. It is a solid choice for travelers who want to disconnect from their phones entirely and carry their own library, or for outdoor enthusiasts who need a device that can handle rain, sweat, and water immersion equally well. It is a robust tool for the person who treats their headphones as essential gear rather than just a fashion accessory.

In my opinion, I would buy the Rhyfell Bone Conduction Swimming for myself and for any child I am purchasing for. The 28g weight and the specific ergonomic design make it the superior choice for active use, especially when the goal is to stay connected to your surroundings without sacrificing audio quality. While the SAMVEK is a capable device with excellent file support, the Rhyfell's focus on the "swimming population" and its latest Bluetooth 6.0 chip gives it the edge in real-world performance. If you are looking for a reliable kids headset for remote work or a safe pair of headphones for a growing athlete, the Rhyfell's balance of safety, weight, and battery life is hard to beat.
