If you want a dedicated swim companion that lets you dive deep without a phone and offers all-day battery life, choose mojawa Purra Swim Bone; if you need a lightweight, open-ear option strictly for land-based workouts where situational awareness is your top priority, choose shokz OpenMove.
• mojawa Purra Swim Bone: Its biggest strength is the IP68 waterproof rating and 32GB internal storage, allowing true wireless swimming; its trade-off is a larger form factor and higher latency (200ms) compared to standard headphones.
• shokz OpenMove: Its biggest strength is its ultra-lightweight 29g design and secure fit for daily running; its trade-off is a short 6-hour battery life and no capability for underwater use.
• Who each pick is for: The mojawa is for swimmers and athletes who hate carrying phones in the pool, while the shokz is for runners, hikers, and cyclists who need to hear traffic and surroundings clearly.
The mojawa Purra Swim Bone is engineered for a specific, demanding environment: water. If you are someone who treats swimming as a primary workout rather than just a casual dip, this device changes the game. It carries an IP68 professional full waterproof rating, which means it isn't just splash-resistant like many sport headphones. You can take it into deep pools, open water training sessions, or even use it in the shower without worry. The construction relies on a flexible titanium alloy frame wrapped in skin-friendly silicone, ensuring it stays put even when you are doing laps or treading water vigorously.
What sets this model apart from almost every other bone conduction headset is the integrated 32GB of local storage. This feature allows you to load thousands of songs directly onto the device, supporting lossless formats like FLAC, WAV, and MP3. Because it has its own memory, you don't need to carry your smartphone into the pool with you. You simply pair it via Bluetooth for daily use, switch to MP3 mode when you hit the water, and enjoy uninterrupted music. The dual-mode connectivity is seamless; you can toggle between connecting to your phone for calls and switching to offline playback instantly.

This product is ideal for the serious athlete who wants to disconnect from their phone but stay connected to their playlist. However, it might not be for everyone. With a weight of 32 grams, it is slightly heavier than some ultralight competitors, though the ergonomic design keeps it comfortable for long sessions. The audio latency is listed at 200 milliseconds, which is noticeable if you are trying to sync video perfectly, but irrelevant for music listening. If you are looking for the best headphone for exercise that involves water, this is the only logical choice on the market right now.
The shokz OpenMove is built for the person who lives their life outdoors and needs to stay aware of their environment at all times. It features an open-ear design that leaves your ear canal completely clear, meaning you can listen to podcasts or music while still hearing cars, cyclists, and people talking around you. This makes it an exceptional tool for safety during urban runs or cycling commutes. The headset uses a wraparound titanium frame that is both rugged and sweat-resistant, designed to withstand intense workouts without slipping. At just 29 grams, it is incredibly light, reducing the feeling of fatigue during long wear sessions.
While it lacks the waterproofing and massive storage of the mojawa, it excels in versatility for land-based activities. The device supports Bluetooth 5.1 and connects easily to Android, iOS, and Windows devices within a 33-foot range. It delivers balanced audio with rich bass through its cheekbone conduction technology, ensuring you get a decent sound profile without blocking out the world. The package includes a carrying bag and five pairs of stickers, adding a touch of personalization that appeals to users who want their gear to look unique.
However, the battery life is a significant constraint here. With only 6 hours of continuous playback, you will need to charge it frequently if you are using it for long-distance events or multi-day trips. It does support quick charging, but the total capacity is much lower than what the mojawa offers. This product is perfect for the runner who doesn't want to deal with heavy equipment or complex setup procedures. It is less suitable for anyone planning to swim or engage in high-intensity water sports, as it is only sweatproof, not fully waterproof.
• Best for swimming: mojawa Purra Swim Bone, thanks to its IP68 rating and ability to function fully underwater without a phone.
• Best for battery endurance: mojawa Purra Swim Bone, offering up to 15 hours of playback versus the shokz's 6 hours.
• Best for situational awareness: shokz OpenMove, with its open-ear design optimized for outdoor safety and environmental sound.
• Best for storage flexibility: mojawa Purra Swim Bone, featuring 32GB internal memory for offline playlists.
• Best for weight and comfort: shokz OpenMove, weighing in at a featherlight 29g for all-day wear.
• Best for call quality: Both offer clear hands-free calling, but mojawa includes environmental noise cancellation for wind reduction.
• Best for durability in water: mojawa Purra Swim Bone, built to resist immersion, dust, and splashes.
• Best value for swimmers: mojawa Purra Swim Bone, as it eliminates the need to buy a separate waterproof player.
After analyzing the specifications and intended use cases, I would buy the mojawa Purra Swim Bone if my primary goal was to have a versatile workout partner that handles both land and water. The inclusion of 32GB of storage and the IP68 waterproof rating gives it a utility that the shokz simply cannot match. While the shokz OpenMove is a fantastic, lightweight option for runners, its limited battery life and lack of water resistance make it feel like a single-purpose tool. The mojawa, however, feels like a complete solution for anyone who trains hard across different environments. Ultimately, if you are looking for the best headphone for exercise that requires durability and independence from your phone, especially for a kid who might want to swim, the mojawa is the superior choice.
Only the mojawa Purra Swim Bone is safe for swimming. It has an IP68 rating that supports deep underwater use, whereas the shokz OpenMove is only sweatproof and should never be submerged.
The mojawa Purra Swim Bone lasts significantly longer, offering up to 15 hours of playback compared to the 6 hours provided by the shokz OpenMove.
Both are excellent for cycling due to their open-ear designs that keep you aware of traffic. However, the mojawa is better if you plan to ride in the rain, while the shokz is lighter for long, dry rides.
Not with the mojawa Purra Swim Bone, as it has 32GB of built-in storage. With the shokz OpenMove, you must carry your phone nearby to stream music wirelessly.
