If you want a rugged, safety-focused headset for night workouts with an integrated light and robust sweat protection, choose Potewek Bone Conduction Open; if you need the absolute lightest weight possible for all-day comfort and superior wireless range, choose Kinglucky Open Ear Bone.
• Potewek: Its standout feature is the built-in LED safety light for visibility, paired with IP54 resistance against sweat and splashes; however, it lacks full waterproofing for submersion and uses an older Bluetooth standard.
• Kinglucky: It wins on pure comfort with its featherweight 23.5g design and offers a modern Bluetooth 5.4 connection with a massive 33-foot range, though it misses the active safety lighting of the competitor.
• Who picks Potewek: Runners who train in low-light conditions and need that extra layer of visibility without sacrificing audio awareness.
• Who picks Kinglucky: Users prioritizing long-wear comfort during extended sessions or those needing a stable connection over greater distances from their device.
The Potewek Bone Conduction Open is engineered specifically for the outdoor athlete who values situational awareness above all else, particularly when the sun goes down. The defining feature here is the built-in LED safety light. This isn't just a gimmick; it serves a critical function for early morning jogs or evening training sessions where visibility is compromised. When you are running on a dark trail or cycling through city streets after dusk, having that light integrated directly into your audio device provides a tangible sense of security. It ensures drivers and other pedestrians can see you before you even hear them, which is a crucial safety layer that standard headphones simply cannot offer.
Its construction focuses heavily on durability during intense physical activity. With an IP54 rating, this headset is designed to handle significant amounts of sweat and light splashes, making it a reliable companion for high-intensity gym sessions, hot summer runs, or unpredictable weather. The enclosure combines Acrylonitrile Butadiene Styrene (ABS) with soft silicone, creating a shell that is tough enough to withstand impact while remaining comfortable against the skin. The open-ear design ensures you never feel isolated from your environment, allowing traffic noise and conversation to pass through naturally while you enjoy your music.

However, you should skip this model if your primary goal involves swimming or total water immersion. While the IP54 rating handles sweat and rain well, it does not meet the standards required for submersion. Additionally, the battery life sits at 10 hours, which is solid for most daily workouts but might be limiting for ultra-endurance events. If you are looking for the "best in ear earbuds for swimming," this unit will not fit the bill due to its lack of waterproofing certification beyond splash resistance. It is strictly a land-based sports tool for runners, cyclists, and hikers who need to stay seen and heard.
The Kinglucky Open Ear Bone Headphones are defined by their obsession with weight and connectivity. At just 23.5 grams, or roughly 0.8 ounces, these are among the lightest options available on the market. This ultra-light build is not just about specs; it translates to a physical sensation where the device almost disappears on your head. The flexible wraparound design grips securely, yet the plush silicone pads cushion your ears, preventing the pressure points and fatigue that often plague heavier bone conduction units. If you plan to wear headphones for your entire commute, a long workday, or a marathon-length hike, this reduced mass makes a world of difference in how your head feels after several hours of use.
Wireless performance is another area where Kinglucky shines. It utilizes Bluetooth 5.4 technology, which is a generation ahead of many competitors. This upgrade allows for a stable connection up to 33 feet away from your source device, far exceeding the 10-meter range found in older models. This range is ideal if you move around a large yard, run a long track, or simply want to leave your phone in your locker without worrying about dropouts. The sound profile is tuned to deliver rich, immersive audio with clear vocals and bass notes, minimizing distortion even during movement. The open-ear architecture reduces sound leakage, ensuring that those sitting next to you on a bus or bench don't hear what you are listening to.
Despite its impressive weight and connectivity, there are trade-offs to consider. The device carries an IPX5 rating, which protects against sweat and light rain, but like the Potewek, it is not suitable for swimming or heavy submersion. It also lacks any form of active lighting or safety features for low-visibility environments. If you are searching for a "headphone for swimming" or need to see in the dark while running, this model falls short. However, for users who prioritize a seamless, lag-free connection and want to avoid the strain of heavy equipment on their temples, the Kinglucky is a compelling choice for daily active use.
• Best for Night Safety → Potewek Bone Conduction Open: The integrated LED safety light is a unique advantage for anyone running or cycling in low-light conditions.
• Best for All-Day Comfort → Kinglucky Open Ear Bone: The 23.5g weight and plush padding make it the superior choice for extended wear without ear fatigue.
• Best Wireless Range → Kinglucky Open Ear Bone: Bluetooth 5.4 offers a 33-foot range compared to the 10 meters of the Potewek, reducing dropout risks.
• Best Sweat Resistance → Tie: Both offer strong protection (IP54 vs IPX5), suitable for intense workouts and rain, though neither is swim-ready.
• Best Driver Size → Potewek Bone Conduction Open: Features oversized 13mm dynamic drivers, potentially offering fuller sound and enhanced bass.
• Best Value for Connectivity → Kinglucky Open Ear Bone: The newer Bluetooth 5.4 chip ensures better stability and lower latency than the Bluetooth 6.0 implementation in the Potewek.
• Best for Low-Light Training → Potewek Bone Conduction Open: Only this model includes the visual safety component needed for dawn or dusk exercise.
• Best for Long Commutes → Kinglucky Open Ear Bone: The lighter weight and longer battery life make it more comfortable for prolonged periods of use.
After analyzing the specifications and design philosophies of both units, I would buy the Kinglucky Open Ear Bone for my personal collection. While the Potewek's safety light is an innovative feature for specific night-time scenarios, the Kinglucky's combination of ultra-lightweight comfort and advanced Bluetooth 5.4 connectivity addresses the most common pain points for bone conduction users: ear fatigue and connection drops. In my opinion, the freedom of moving freely without feeling weighed down by the hardware is the single most important factor for a headphone that is meant to be worn for hours. That said, if your primary use case involves swimming or requires a dedicated safety light for night runs, you should look elsewhere. For general sports, commuting, and all-day listening, the Kinglucky strikes the better balance of performance and comfort.
Neither the Potewek nor the Kinglucky is rated for swimming. Both have IP54 or IPX5 ratings, which protect against sweat and splashes, but they are not waterproof enough for submersion in a pool or open water.
Both models offer approximately 10 hours of average playback time, so you can expect similar endurance whether you choose the Potewek or the Kinglucky for your daily workout.
Both devices utilize open-ear bone conduction technology, which minimizes sound leakage compared to traditional speakers. The Kinglucky specifically mentions optimized acoustic structures to reduce leakage further, keeping your audio private.
The product details do not explicitly state that a cable is included for either model, with some descriptions suggesting users may need to provide their own Type-C cable. Check the current listing details on Amazon for the most accurate accessory information.
