If you want a dedicated, swim-proof device with massive internal storage for underwater workouts and long battery life, choose Rhyfell Bone Conduction Swimming; if you need a multifunctional recording tool with AI translation and camera capabilities for land-based cycling or street running, choose generic Bone Conductions.
• Rhyfell Bone Conduction Swimming: Its greatest strength is the IP68 waterproof rating that allows full submersion up to 5 meters, paired with 32GB of built-in memory for phone-free listening. The trade-off is the lack of camera or smart AI features, as it focuses purely on audio performance in aquatic environments. This pick is for serious swimmers and triathletes who need zero distractions and total water protection.
• generic Bone Conductions: Its biggest advantage is the integrated 1080P HD camera with EIS stabilization and AI voice translation, making it a dual-purpose gadget for content creators and travelers. The trade-off is the lower IP54 water resistance, which handles splashes but cannot survive submersion, and the smaller 8GB internal storage. This pick is for cyclists and runners who want to record their POV adventures without carrying a separate camera.
The Rhyfell Fit 5 is engineered specifically for the aquatic athlete who refuses to compromise on safety or audio quality. With a professional IP68 waterproof certification, this device can be fully submerged between 2 to 5 meters, turning any pool or open water session into a private concert hall. Unlike standard headphones that might fail when dunked, this unit is designed to withstand the pressure and moisture of actual swimming, surfing, or triathlon training. The liquid silicone material and ergonomic design ensure it stays secure even during high-intensity laps, preventing the common frustration of earbuds slipping out mid-stroke.
For those with larger ears who struggle to find a secure fit for traditional earbuds, the 28g ultra-lightweight frame offers a compelling solution. The open-ear design leaves your auditory canal completely unobstructed, which is critical for situational awareness near water hazards or busy lanes. Because it houses 32GB of high-speed storage capable of holding over 8,000 songs, you can leave your phone entirely behind. The transfer speed is reportedly 18 times faster than previous generations, meaning you can load your entire workout playlist in minutes rather than waiting for a slow sync.

This product is ideal for the runner who wants to train for hours without charging anxiety, boasting a 10-hour playtime that doubles the industry standard. However, if you are looking for a device that records your run or translates foreign languages for travel, this is not the right tool. It is a focused piece of hardware designed for one primary goal: delivering uninterrupted music while keeping your ears open and safe during intense physical exertion, particularly where water is involved.
The generic Bone Conductions model serves a different demographic entirely, catering to the creator and the tech-savvy commuter who views headphones as a multi-tool. Its standout feature is the built-in 8MP camera with Electronic Image Stabilization (EIS), capable of capturing stable 1080P footage at 30fps directly from your head. This turns a simple run or bike ride into an opportunity to document action shots without needing to hold a phone or mount a GoPro. The 8GB internal memory provides a secure place to store these video files, ensuring your memories aren't lost if you forget your smartphone.
Beyond the camera, the inclusion of AI intelligent voice capabilities powered by OpenAI makes this headset unique for international travelers or gym-goers in foreign countries. It can assist with instant bilingual voice translation and fast photo identification, helping you navigate signs or communicate across language barriers. The open-ear hook design, constructed from durable ABS material, ensures stability during high-impact sports like road biking or trail running. While it offers deep audio resolution and clear spatial sound, the focus here is clearly on capturing your environment and interacting with it digitally.
However, the limitations become apparent when considering water exposure. With an IP54 rating, this device can handle sweat and light rain, but it is not certified for submersion. If you plan to dive into a pool or surf in rough waves, this unit will not survive. Additionally, the 10-hour battery life matches the Rhyfell, but the power draw from the camera and AI functions might impact real-world usage depending on how heavily you rely on those features. This is best suited for someone who prioritizes recording capabilities and smart features over pure audio immersion or aquatic durability.
• Best for swimming and underwater use → Rhyfell Bone Conduction Swimming, due to its IP68 rating allowing full submersion.
• Best for recording POV videos → generic Bone Conductions, featuring the integrated 1080P camera with EIS stabilization.
• Best for large internal storage → Rhyfell Bone Conduction Swimming, offering 32GB for thousands of songs versus 8GB on the generic model.
• Best for AI translation and navigation → generic Bone Conductions, providing OpenAI-powered voice assistance for travelers.
• Best for lightweight comfort → Rhyfell Bone Conduction Swimming, weighing only 28g with liquid silicone materials for sensitive wearers.
• Best for rugged land sports → generic Bone Conductions, with its ABS earhooks designed for cycling and trail running.
• Best for battery longevity in audio mode → Both offer 10 hours, but Rhyfell may sustain longer pure audio sessions without draining extra power for cameras.
• Best for "big ears" and open-ear security → Rhyfell Bone Conduction Swimming, specifically designed with a secure fit for the swimming population.
After analyzing the specifications and intended use cases, I would personally buy the Rhyfell Bone Conduction Swimming. The decision comes down to the specific demands of the user; while the camera features of the generic model are intriguing, they feel like gimmicks for most athletes who just want to listen safely. The Rhyfell's IP68 rating and 32GB storage solve the two biggest pain points for swimmers: water damage and the inability to bring a phone. Furthermore, the 28g weight and ergonomic design make it the superior choice for sleep headphones for big ears or ear clip headphones for big ears who need a non-intrusive fit that stays put. In my opinion, a device that excels at its primary function—delivering safe, immersive audio in harsh conditions—is far more valuable than one that tries to do too many things mediocrely.
Only the Rhyfell Bone Conduction Swimming is rated IP68, meaning it can be fully submerged up to 5 meters. The generic Bone Conductions are only IP54 rated and should not be submerged in water.
Yes, both models feature open-ear designs, but the Rhyfell is specifically engineered with a 28g lightweight frame and liquid silicone to provide a secure, comfortable fit for athletes, including those with bigger ears who often struggle with tight earbuds.
There is a major difference; the Rhyfell includes 32GB of built-in memory capable of storing over 8,000 songs, whereas the generic model only has 8GB, which is primarily intended for storing camera footage.
Not necessarily. The Rhyfell has enough internal storage to play music independently in MP3 mode, so you can leave your phone behind. The generic model also has 8GB storage but is better utilized for video recording and relies more on Bluetooth for general playback.
