If you want a do-everything open-ear training partner for running, lifting, and everyday sweat, choose JBL Endurance Zone Open; if you need headphones that actually play music underwater while you swim, choose DOOGEEEco Bone Air Swim.
• JBL Endurance Zone Open – biggest strength: OpenSound directional audio with adaptive bass boost, plus a huge 32-hour total battery (8 in the buds, 24 in the case) and a rapid 10-minute quick charge.
• JBL Endurance Zone Open – biggest trade-off: No built-in storage and no MP3 mode, so it depends entirely on a Bluetooth connection — meaning it simply cannot go underwater with you.
• DOOGEEEco Bone Air Swim – biggest strength: A genuine 64GB music vault that plays in MP3 mode with no phone required, backed by IP68 waterproofing rated for 2m of immersion for up to 2 hours.
• DOOGEEEco Bone Air Swim – biggest trade-off: Shorter battery life (up to 8 hours wireless, 5 hours in MP3 mode at full volume) and a bone-conduction sound signature that trades deep, thumping bass for situational awareness.
• Who each pick is for: JBL for land-based runners and gym-goers who want long battery and clear calls; DOOGEEEco for swimmers and multi-sport athletes who need music in the water and off-grid playback.
The Endurance Zone Open is built around one idea: stay aware while you train hard. JBL's OpenSound technology fires directional audio into your ear while leaving the canal open, and an adaptive bass boost keeps the low end from disappearing. If you run on roads, ride a bike, or lift in a busy gym, that open design is the whole point — you hear traffic, training partners, and your surroundings without pulling a bud out.
Where it really pulls ahead is stamina and durability. You get up to 8 hours in the earbuds and 24 more in the charging case, which adds up to a claimed full week of training on a single charge. Run out mid-week and a 10-minute USB-C top-up buys you 3 more hours. The IP68 rating means sweat, rain, saltwater, sand, and humidity are all fair game, and the liquid silicone earhook with memory wire is designed to hold its shape rep after rep so you're not fiddling with fit mid-stride. Bluetooth 5.3, touch controls, and voice-assistant support round it out, and four beamforming mics (two per earbud) with a windproof design target clear calls even on a breezy run.
Who should buy it: runners, cyclists, hikers, and gym regulars who want long battery life, a secure hook-style fit, and the ability to hear what's happening around them. Who should skip it: swimmers, and anyone who wants to leave their phone behind. There's no onboard memory here, so it's Bluetooth-only — and Bluetooth doesn't travel through water. If pool laps are your priority, this isn't the one.
The Bone Air Swim is the more specialized tool, and it's honest about it. Its headline trick is dual bone-and-air conduction drivers: bone conduction handles crisp highs and mids while a separate air-conduction driver adds the deep bass that bone conduction alone usually can't deliver. The result is a fuller stereo sound than typical bone-conduction sets, while the open-ear design still keeps your ear canals clear so you can hear traffic and ambient noise.
The real differentiator is the 64GB of built-in memory — enough for up to 16,000 tracks — paired with a dual-mode setup. Outdoors, it runs as a normal Bluetooth 5.4 headphone for running and cycling. Underwater, you switch to MP3 mode and it plays entirely from local storage, because wireless signals can't transmit through water. The IP68 rating is specifically a swimming-grade, double-sealed design rated for immersion to 2m for up to 2 hours, which makes it a legit option for pool training and open-water swims. Battery runs up to 8 hours in Bluetooth mode at 75% volume, or 5 hours in MP3 at full volume, and a 10-minute fast charge returns 2 hours of playback.
Comfort and kit are clearly aimed at athletes. A 26.5g frame uses silicone ear hooks and a titanium memory steel wire, with an adjustable strap that fits smaller heads, including women and kids. You also get a full accessory pack: magnetic charging cable, silicone and sponge swimming earplugs, an anti-slip elastic strap, and a hard carry case.
Who should buy it: swimmers first, plus triathletes, cyclists, and anyone who wants phone-free playback from built-in storage. Who should skip it: people who mainly want maximum battery life and don't care about underwater playback — and anyone who prefers a traditional in-ear or hooked fit over bone conduction.
• Best for swimming → DOOGEEEco Bone Air Swim. It's the only one of the two rated for 2m immersion and the only one that plays from local storage when Bluetooth can't reach you.
• Best for battery life → JBL Endurance Zone Open. Up to 32 hours total versus a max of 8 hours on the DOOGEEEco.
• Best for phone-free playback → DOOGEEEco Bone Air Swim. 64GB of onboard memory holds up to 16,000 tracks; the JBL has none.
• Best for clear calls → JBL Endurance Zone Open. Four beamforming mics with a windproof design versus no dedicated call array on the DOOGEEEco.
• Best for secure hooked fit on land → JBL Endurance Zone Open. Liquid silicone earhooks with memory wire are purpose-built to stay put during runs and lifts.
• Best for light, adjustable comfort → DOOGEEEco Bone Air Swim. A 26.5g frame with a titanium memory wire and an adjustable strap that fits smaller heads.
• Best for a complete out-of-the-box kit → DOOGEEEco Bone Air Swim. It ships with earplugs, an anti-slip strap, and a hard case.
• Best for everyday training with awareness → either, but I'd lean JBL. If your workouts are on land, the Endurance Zone Open's battery and call quality are the more useful combination.
If I had to pick one, I'd buy the DOOGEEEco Bone Air Swim — but only because it does something the JBL simply can't. In my opinion, the 64GB of onboard storage and the true swimming-grade IP68 rating make it the more capable tool for anyone whose training includes water, and the dual-driver design is a smart way to recover the bass that bone conduction usually loses. That said, if your world is strictly land-based — running, cycling, the gym — I'd go with the JBL Endurance Zone Open instead. Its 32-hour battery, quick charge, and four-mic call quality are genuinely better for that life, and its earhook fit is built for exactly that kind of training. Match the tool to the workout and you won't regret either.
Yes — its IP68 rating is specifically described as swimming-grade and double-sealed, supporting immersion to 2m for up to 2 hours. Just remember to switch to MP3 mode, since Bluetooth signals don't travel through water.
I wouldn't. Its IP68 rating covers sweat, rain, saltwater, sand, and humidity as training conditions, but it has no onboard storage and relies on Bluetooth, which won't stay connected underwater.
The JBL Endurance Zone Open, clearly — up to 8 hours in the earbuds plus 24 in the case, for 32 hours total, with a 10-minute charge adding 3 hours. The DOOGEEEco tops out at 8 hours wireless or 5 hours in MP3 mode.
For the JBL, yes — it's Bluetooth-only. For the DOOGEEEco, no: its 64GB of built-in memory lets you play music directly in MP3 mode, which is the whole point for swimming.
I'd recommend the JBL Endurance Zone Open for that. Longer battery, a secure memory-wire earhook, and four beamforming mics for calls make it the better land-training companion. Prices change, so check the current price on Amazon before you commit.
