If you want a bone conduction headphone you can actually take into the water, choose Sudroid Bone Conduction Headphones; if you need longer battery life for dry-land training and everyday listening, choose BETAHEAR Bone Conduction Headphones. That is the short version, and it comes down to one spec that separates these two more than anything else: the Sudroid set is built around swimming, while the BETAHEAR set is built around stamina and comfort on land.
• Sudroid Bone Conduction Headphones — biggest strength: IP68 waterproofing plus 16GB of built-in memory and an MP3 mode, so it works as a standalone player without a phone nearby. Biggest trade-off: shorter battery window (6–8 hours of music or talk) and an older Bluetooth 5.0 radio.
• BETAHEAR Bone Conduction Headphones — biggest strength: a 10-hour battery and a 240-hour standby figure, with a 29g frame and Bluetooth 5.3. Biggest trade-off: it is positioned as sweat-resistant rather than swim-rated, so it stays out of the pool.
• Sudroid Bone Conduction Headphones is for: swimmers, triathletes, and anyone who wants music in the water without a phone.
• BETAHEAR Bone Conduction Headphones is for: runners, cyclists, hikers and commuters who want a light, all-day open-ear headset with a microphone for calls.
• Quick call: water first, pick Sudroid. Time and lightness first, pick BETAHEAR.
The Sudroid set is the one in this pair that is explicitly designed around water. Its listing carries IP68 waterproofing, which is a step beyond the IPX7 class you normally see on sports headphones — it is meant to survive submersion rather than just a heavy sweat session or a rainstorm. On top of that, the headphone has 16GB of internal memory and can switch between MP3 player mode and Bluetooth mode. That combination matters more than it sounds: Bluetooth does not travel through water, so a swimmer needs on-board storage, and 16GB is roughly enough for thousands of tracks depending on file size and bitrate. The supported formats include WMA, MP3, WAV, APE and FLAC, so lossless files are on the table.
The build is a titanium alloy wraparound headband with an adjustable silicone band, listed at 42g. That is heavier than the BETAHEAR set, but the weight is spread across a wraparound frame rather than sitting on your ears, and the silicone band is adjustable to fit different head sizes. Charging takes about 2 hours, and the battery runs 6–8 hours of music or talk time — fine for a swim block, a gym session, or a run, but not a full day of continuous use. Bluetooth 5.0 gives a 10m wireless range and works with Android and iPhone. Controls are touch-based for volume, and the set uses sound isolation for noise control, which is a slightly different approach to the usual "hear everything" open-ear pitch.
Who should buy it: swimmers, open-water and pool lap swimmers, triathletes in training, and anyone who wants to run or lift without carrying a phone. If your training happens in water, this is the pick that makes sense — the MP3 mode and the IP68 rating are the whole point.
Who should skip it: if you mostly want a headset for calls and podcasts across a long workday, the 6–8 hour window and the older Bluetooth version will feel limiting compared with the alternative. If you dislike wraparound bands or prefer the absolute lightest possible frame, the 42g weight is worth thinking about too.
The BETAHEAR set takes the opposite approach: it trades waterproofing depth for endurance and low weight. The headline figure is 10 continuous hours of music, calls and podcasts, with standby time up to 240 hours. For a runner, a cyclist or someone who wears open-ear headphones through a working day, that is the number that actually changes how you use the product — you charge it far less often, and you are less likely to get caught mid-commute with a dead battery.
At 29g it is genuinely light, and the frame is built from a high-strength memory titanium alloy neck strap with a food-grade silicone pad that the listing says can bend 360° without deforming. In practice that means you can toss it in a bag without worrying about the band losing its shape, and the skin-friendly pad reduces irritation on longer wears. Bluetooth 5.3 is the newer radio here, and the set includes a built-in microphone with media controls on the headset itself, so answering calls and skipping tracks does not require reaching for your phone.
What it does not claim is swimming. The listing describes it as sweat-resistant, which covers running, cycling, hiking, driving and indoor workouts, but it is not presented as something you submerge. It also lists no noise control, so you get the natural open-ear awareness and nothing else — which is exactly what most outdoor athletes want, but worth knowing if you expected any isolation. There is no wired jack, so it is wireless-only.
Who should buy it: runners, cyclists, hikers, gym-goers, drivers and commuters who want a light open-ear headset with a mic and a battery that lasts a full training day or workday. If you never swim in your headphones, the extra waterproofing on the other set buys you nothing.
Who should skip it: swimmers and anyone who wants built-in music storage with no phone in range. If your main use is laps in a pool, this set is not the right tool.
• Best for swimming → Sudroid Bone Conduction Headphones. IP68 waterproofing is the deciding spec here; the BETAHEAR set is sweat-resistant, not swim-rated.
• Best for phone-free workouts → Sudroid Bone Conduction Headphones. 16GB of internal memory plus MP3/Bluetooth switching means you can leave the phone in the locker.
• Best for battery life → BETAHEAR Bone Conduction Headphones. 10 hours of continuous play and up to 240 hours standby beats the 6–8 hour window on the Sudroid.
• Best for all-day lightness → BETAHEAR Bone Conduction Headphones. At 29g versus 42g, it is the set you forget you are wearing.
• Best for calls and podcasts → BETAHEAR Bone Conduction Headphones. Built-in mic plus newer Bluetooth 5.3 and media controls on the headset.
• Best for lossless file playback → Sudroid Bone Conduction Headphones. Its MP3 mode supports FLAC, APE, WAV and WMA directly from internal storage.
• Best for outdoor awareness → a tie. Both use open-ear bone conduction design, so both keep your ears open to traffic and surroundings.
• Best for mixed land-and-water training → Sudroid Bone Conduction Headphones, because it covers the pool and the run; the BETAHEAR covers only the run.
If I were buying one of these two, I would pick the Sudroid Bone Conduction Headphones, and the reason is simple: waterproofing is the hardest spec to work around. You cannot add water resistance to a headphone that does not have it, and the pool is exactly where Bluetooth headphones usually fail you. The 16GB MP3 mode solves the same problem from a different angle. The 6–8 hour battery is a real limitation, and the BETAHEAR set is the better daily driver for land training — but for anyone whose training touches water, the Sudroid is the one that will still be working when the alternative has to stay in the bag.
are headphones waterproof
Not all of them — it depends entirely on the rating. In this pair, the Sudroid Bone Conduction Headphones carry an IP68 waterproof rating, which is designed for submersion, while the BETAHEAR Bone Conduction Headphones are described as sweat-resistant for daily exercise. If you need to swim with headphones, look specifically for an IP68 or similar swim-rated claim rather than assuming "sports" means "waterproof."
are headphones water resistant
Water resistance and waterproofing are not the same thing, and the numbers tell you which is which. The BETAHEAR set is sweat-resistant, which covers perspiration, light rain and general outdoor use, but it is not presented as something you submerge. The Sudroid set goes further with IP68, which is the rating to look for if you want to take the headphone into a pool.
Bluetooth 5.3 on the BETAHEAR set is a newer generation than Bluetooth 5.0 on the Sudroid, and newer versions generally mean more efficient, more stable connections. Both use bone conduction drivers with a 20Hz–20kHz frequency range, so the underlying sound approach is the same — the difference is in connection tech and battery efficiency, not in the driver type.
That is the crossover case, and it pushes you toward the Sudroid Bone Conduction Headphones, because it handles both the pool and the run while the BETAHEAR set only handles the run. You give up battery hours and some lightness, but you gain a headphone that works in every session. If swimming is only a rare thing for you and battery life matters more, the BETAHEAR is the more comfortable everyday choice. Either way, check the current price on Amazon before deciding, since that is the one variable that can flip the call.
