What it is and what it solves\nMonodeal’s bone conduction headphones are designed to be worn open-ear, making them suitable for water sports and outdoor activities while keeping your ears free. The IP68 rating indicates robust water and dust resistance, so you can swap poolside and canal runs without worrying about splashes or sweat. If you prioritise staying aware of your surroundings, these open-ear headphones offer a different listening experience than traditional in-ear devices.\n\n## How it works and key features\nThe headset streams audio via Bluetooth 5.4 for a stable connection up to about 10 metres and includes built-in MP3 memory (8 GB) to store up to around 1500 songs. A dual-mode setup lets you switch between Bluetooth listening and standalone MP3 playback with a quick double-click on the control key. Battery life is quoted as up to 8 hours of continuous playback or calls, with a 180 mAh cell and a charging time of roughly 2 hours. Practical for swimmers, cyclists and runners alike, the device aims to blend water-ready durability with everyday convenience.\n\n## What to like about it\nOn the paper merits include open-ear comfort, which reduces the feeling of pressure inside the ear canal and helps you stay alert in traffic or on busy paths. The bone conduction approach can deliver deeper bass and crisp highs while keeping the ears free, which some users find more comfortable during longer sessions. The IP68 waterproofing plus sweat and dust resistance extends its usefulness beyond the pool, catering to rainy runs or gym sessions under a ceiling of steam.\n\n## What might not convince everyone\nThe open-ear design isn’t universally preferred, some listeners may feel the soundstage differs from closed-back, in-ear models. The 8 GB MP3 storage, while useful, may feel limiting for users with large music libraries. Also, the absence of active noise cancellation means you’ll still hear ambient noise, which can be a pro or con depending on where you train.\n\n## Who it’s for\nIt suits swimmers who want music or calls without occluding the ears, fitness enthusiasts who value situational awareness, and anyone seeking a water-friendly setup for pool sessions or rainy outdoor workouts. If you mainly listen to podcasts or prefer a high-end audio experience with deep isolation, this model might not be the best fit.\n\n## When it makes sense to buy\nConsider this device if you need waterproof, open-ear audio that works in water and how important quick mode switching is during workouts. The combination of Bluetooth streaming and offline MP3 playback offers flexibility for those who train in varied environments and may not always have a reliable Bluetooth signal.\n\n## What to check before buying\nVerify that IP68 protection covers the scenarios you face—submersion depth and duration can matter for certain water activities. Check the fit and weight for comfort during longer sessions, and consider whether 8 GB of internal memory meets your music needs. Also, confirm device controls are easy to use when you’re wearing swim caps or goggles.\n\n## Practical use scenarios\nImagine finishing a lap and quickly switching from Bluetooth to MP3 playback without pulling out a device, or taking a call mid-run with hands free while remaining aware of traffic around you. The open-ear design means you can hear a coach’s whistle or an approaching cyclist while listening to your playlist.\n\n## Final purchase decision\n## What to consider when choosing\nYou’ll like it if you want water-ready, open-ear listening with a straightforward mode switch and a built-in MP3 option for workouts where Bluetooth isn’t reliable. It may be less appealing if you prioritise absolute sound isolation or require substantial on-device storage for music beyond 1500 tracks.\n\n## FAQ\n- How waterproof is it for swimming?
