How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want maximum situational awareness on land with the lightest possible fit, choose LazyGoose Open Ear Bone; if you need headphones that keep working when you're actually underwater, choose esonstyle Swimming Headphones Underwater.
• LazyGoose Open Ear Bone — biggest strength: a true open-ear bone conduction design that leaves your ear canals completely free, so traffic, pedestrians and announcements stay audible while you run or ride.
• LazyGoose Open Ear Bone — biggest trade-off: battery life is the weak spot here. The spec sheet lists about 2 hours of playtime at 80% volume, which is a short window compared with the other pick.
• esonstyle Swimming Headphones Underwater — biggest strength: an IP68 rating that handles submersion up to 3 meters for 60+ minutes, plus 8GB of built-in storage so you can leave your phone on the shore.
• esonstyle Swimming Headphones Underwater — biggest trade-off: Bluetooth doesn't work underwater at all. You have to double-click the MFB button into MP3 mode before you get in the pool, and that's a habit you have to build.
• Who each pick is for: LazyGoose suits runners, cyclists and commuters who want awareness and a featherweight fit; esonstyle suits swimmers, surfers and kayakers who need audio that survives the water.
The LazyGoose OPENEAR Bone G1 is built around one idea: keep your ears open and your surroundings audible. Audio travels through your cheekbones via a bone conduction driver, so nothing sits inside your ear canal. If you run on busy streets or cycle through traffic, that's the whole point — you hear the music and the car behind you at the same time. The flexible titanium frame and soft silicone wrap are meant to stay put during hard efforts, and the listed 3.2-ounce weight keeps it from feeling like a burden on longer sessions.
Connectivity is where this model leans modern. Bluetooth 6.0 gives you a stable link up to roughly 10 meters, and pairing is a simple long-press on the MFB button to select "OPENEAR Bone G1" on your device. Button controls handle play/pause, volume, calls and your voice assistant without reaching for your phone. The IPX7 rating covers heavy sweat, rain and accidental splashes — fine for outdoor workouts, though I'd note that IPX7 is a splash-and-sweat rating, not a dive rating, so don't treat it as swim gear.
The honest trade-off is runtime. The spec sheet lists up to 2 hours of playtime at 80% volume, with a full charge in about 50 minutes over USB-C. A voice prompt announces battery levels at power-on, which helps, but two hours is a short leash for anyone planning a long ride or a double workout. The included foam earplugs are a nice touch — they let you block outside noise when you want more bass presence rather than awareness. Buy it if you want open-ear safety, a light titanium frame and quick top-ups between sessions. Skip it if you need all-day battery or you're heading into the water.
The esonstyle X32 is designed for a different job entirely: staying functional when you're submerged. The IP68 rating is the headline — it's rated for depths up to 3 meters for 60+ minutes, which covers lap swimming, surfing, kayaking and heavy rain. It's also bone conduction, so the open-ear awareness benefit carries over to running and cycling on dry land. The 28-gram titanium frame is genuinely light, and the flexible fit is meant to hold through sprints, flip turns and trail descents.
The feature that changes how you use it is the 8GB of built-in memory. That's roughly 2000+ songs stored on the headphones themselves, synced over a magnetic cable. For swimmers this isn't a gimmick — Bluetooth simply doesn't travel through water, so onboard storage is the only way to hear anything mid-lap. The listed 8-hour battery is four times the LazyGoose figure, which makes it viable for marathon training or several swim sessions between charges. Bluetooth 6.0 handles phone streaming and calls when you're dry, and a double-click on the MFB switches between Bluetooth and MP3 mode. In MP3 mode it defaults to sequential playback, with a triple-press for shuffle.
The catch is the mode discipline. Underwater, Bluetooth won't hold a signal, so you must be in MP3 mode before you get in. That means loading files ahead of time and remembering the double-click. The controls are touch-based with passive noise cancellation rather than the button layout on the LazyGoose, which some people love and some people fight with wet fingers. Buy it if you swim, surf or kayak and want music without your phone. Skip it if you only ever use Bluetooth and don't want to manage a local music library.
Side-by-Side: Which Should You Choose?
• Best for underwater use → esonstyle Swimming Headphones Underwater. IP68, 3-meter depth rating for 60+ minutes, and MP3 mode that works where Bluetooth can't.
• Best for battery life → esonstyle Swimming Headphones Underwater. 8 hours listed versus roughly 2 hours at 80% volume on the LazyGoose.
• Best for traffic awareness on land → LazyGoose Open Ear Bone. Open-ear bone conduction keeps cars, pedestrians and announcements audible.
• Best for quick charging → LazyGoose Open Ear Bone. The spec sheet lists a full charge in about 50 minutes over USB-C, with voice prompts announcing battery levels.
• Best for hot, sweaty workouts → LazyGoose Open Ear Bone. IPX7 covers heavy sweat, rain and splashes, which is exactly the running and gym scenario it's built for.
• Best for straightforward controls → LazyGoose Open Ear Bone. Physical buttons for play/pause, volume and calls beat touch controls when your hands are wet or gloved.
• Best for a light, low-fuss fit → either, honestly. Both use titanium frames and open-ear placement, so the deciding factor is water, not weight.
In my opinion, the esonstyle Swimming Headphones Underwater is the better buy for most people comparing these two, because it covers more ground: it swims, it runs, it cycles, and its 8-hour battery and 8GB player make it useful in situations where the LazyGoose's 2-hour runtime would send you hunting for a charger. That said, if your workouts never touch water and your priority is staying alert in traffic with simple button controls, I'd take the LazyGoose Open Ear Bone instead — it does that one job cleanly. Check the current price on Amazon before you commit, since that's the deciding variable I can't weigh for you.
The esonstyle Swimming Headphones Underwater, without question. It carries an IP68 rating for submersion up to 3 meters for 60+ minutes and has 8GB of onboard storage for MP3 playback. The LazyGoose is IPX7, which covers sweat and splashes, not swimming.
Do the esonstyle headphones work with Bluetooth underwater?
The esonstyle, by a wide margin. Its spec sheet lists 8 hours, while the LazyGoose lists about 2 hours of playtime at 80% volume. The LazyGoose does charge faster — roughly 50 minutes to full over USB-C.
Yes, both are open-ear bone conduction designs, so you keep your ears free and stay aware of your surroundings. The LazyGoose adds physical button controls and IPX7 sweat protection, while the esonstyle offers the longer battery and built-in music storage for phone-free runs.
