If you want a single pair of headphones you can actually swim and dive with, choose Soveign Waterproof Headphones; if you need all-day open-ear comfort with long battery life and clear calls for running, commuting and workouts, choose AOTONOK Open Ear Headphones.
These two look similar on the surface — both are open-ear, both are wireless, both are built for sport. But they solve two very different problems. One is designed to survive being submerged. The other is designed to disappear on your ears for hours at a time. Picking the wrong one is easy, so let's break down exactly who each is built for.
• Soveign Waterproof Headphones — biggest strength: IPX8 waterproofing plus a 32GB built-in MP3 player, so you can carry thousands of songs into the water without a phone.
• Soveign Waterproof Headphones — biggest trade-off: Bluetooth is limited underwater, so swimming means switching to MP3 mode, and the design is a bendable bone-conduction band rather than a discreet earbud.
• AOTONOK Open Ear Headphones — biggest strength: Bluetooth 5.4, 50 hours of total playtime, dual-mic noise-canceling calls and a 14.2mm dynamic driver for fuller sound.
• AOTONOK Open Ear Headphones — biggest trade-off: IPX7 protects against sweat, rain and splashes, but it is not built for swimming or diving.
• Who Soveign is for: swimmers, divers and anyone who wants phone-free music in the water.
• Who AOTONOK is for: runners, commuters and gym-goers who want comfort, battery life and call quality all day long.
The Soveign pair is, first and foremost, a swimming headphone. The IPX8 rating means it is built to go deep underwater and stay there, and the whole unit is wrapped in waterproof silicone rather than just coated. That is a meaningfully different level of protection from a splash-resistant earbud, and it is the entire point of this product.
The second half of the story is the 32GB of built-in memory. In MP3 mode it holds more than 6,000 songs, which means you can leave your phone in the locker and still have music for an entire swim session. That phone-free design matters more than it sounds — Bluetooth simply does not travel well through water, so the manufacturer explicitly notes that MP3 mode is the mode to use while swimming. If you were expecting to stream Spotify underwater, that is not what this is. It is a self-contained music player that happens to be shaped like headphones.
The build is also worth noting. The band bends 360 degrees, so you can shape it to your head and it resists the kind of stress that snaps rigid frames. Controls are physical buttons — volume, playback, call answering — and the brand says it can be operated one-handed, which is genuinely useful when you are mid-lap or mid-rep.
Buy it if you swim, dive, or train in water regularly and want your own music without a phone nearby. Skip it if your main activity is running or commuting on land, or if you want touch controls and a discreet earbud-style fit. The bendable band is comfortable and adjustable, but it is a more visible, more structural piece of gear than a pair of ear hooks.
The AOTONOK pair takes the opposite approach. Instead of sealing you off and surviving water, it sits outside your ear canal on soft silicone ear hooks so you keep hearing traffic, training partners and announcements while your music plays. That is the whole appeal of open-ear design for runners and commuters, and AOTONOK leans into it hard.
The spec sheet is stacked for land-based sport. Bluetooth 5.4 gives you a stable connection at up to 33 feet. Battery life is quoted at 50 hours total — 8 hours per charge plus 42 hours from the charging case — and a 15-minute top-up buys you 2 hours of listening. For a runner, that math basically removes charging anxiety from your week.
Sound comes from 14.2mm dynamic drivers, which is a relatively large driver for this category, and AOTONOK says the acoustic tuning is designed to minimize leakage so your audio stays yours. There are dual microphones with noise canceling for calls, which is the difference between a usable call on a windy street and giving up and texting instead. Controls are touch-based, and the set works with both iOS and Android. AOTONOK also backs it with a warranty and support.
Side-by-Side: Which Should You Choose?
• Best for swimming and diving → Soveign Waterproof Headphones. IPX8 and full silicone sealing are built for submersion; AOTONOK's IPX7 is not.
• Best for battery life → AOTONOK Open Ear Headphones. Up to 50 hours total with the charging case versus a swimming-focused design that assumes shorter sessions.
• Best for phone-free workouts → Soveign Waterproof Headphones. 32GB of storage and MP3 mode mean no phone required at all.
• Best for call quality → AOTONOK Open Ear Headphones. Dual microphones with noise canceling are aimed squarely at clear voice calls.
• Best for sound hardware → AOTONOK Open Ear Headphones. A 14.2mm dynamic driver with tuning to reduce leakage is the more audio-forward setup on paper.
• Best for land sports and commuting → AOTONOK Open Ear Headphones. Bluetooth 5.4, touch controls, ear hooks and 33-foot range fit everyday movement better.
• Best for adjustability and durability of fit → Soveign Waterproof Headphones. The 360-degree bendable band lets you shape it and resists breakage at the joints.
• Best for staying aware of your surroundings → AOTONOK Open Ear Headphones. Open-ear ear hooks are designed specifically to let ambient sound in while you run or ride.
My Verdict
In my opinion, most people shopping this comparison should buy the AOTONOK Open Ear Headphones. The combination of Bluetooth 5.4, 50 hours of total playtime, a 14.2mm driver and dual-mic calling covers running, gym, cycling and commuting — which is what the vast majority of buyers actually do — and the ear-hook design keeps you aware of traffic while you train.
Yes — that is what they are designed for. The IPX8 rating and full silicone sealing are intended for underwater use, and the manufacturer notes you should switch to MP3 mode while swimming because Bluetooth is limited in water.
It is not recommended. IPX7 covers sweat, rain and splashes, which is plenty for running and gym work, but it is not a submersion rating like the Soveign's IPX8.
The AOTONOK Open Ear Headphones, on paper. They are rated for up to 50 hours total — 8 hours per charge and 42 hours from the charging case — with a 15-minute quick charge giving 2 hours. The Soveign's appeal is its 32GB of built-in storage rather than extended playtime.
