If you want a familiar true-wireless earbud experience with a charging case, a battery readout you can actually see, and a featherweight hook that stays put, choose JIMBOBO Open Ear Headphone; if you need a phone-free music player built right into the headset, real waterproofing, and a neckband that never falls off, choose Potewek Bone Conduction Headphones.
• JIMBOBO's biggest strength: a complete true-wireless kit — two earbuds, a charging case with an LED battery display, Bluetooth 5.4, dual mics and a claimed 50 hours of total playtime from the case.
• JIMBOBO's biggest trade-off: each bud lasts about 8 hours before it needs the case again, there's no noise cancellation or water-resistance rating, and the open-ear air-conduction design leaks sound both ways.
• Potewek's biggest strength: it works without a phone at all. 32GB of built-in storage, hybrid bone + air conduction drivers, IP68 waterproofing and adaptive noise cancellation in a 25g titanium-and-silicone neckband.
• Potewek's biggest trade-off: the headset itself runs about 10 hours and needs roughly 3 hours to recharge, there's no carrying case or spare pair, and no headphone jack for wired listening.
• Pick JIMBOBO if you want earbuds you can pop in and out all day, take calls on, and top up from a pocket case.
• Pick Potewek if you want one rugged band for sweaty workouts, rainy runs and gym sessions where you'd rather leave your phone in the locker.
The JIMBOBO Open Ear Headphone is a true-wireless pair of earbuds built around an earhook. Each bud is an open-ear, air-conduction design, so nothing plugs your ear canal — you hear your music and the traffic around you at the same time. The hook shape plus a 0.26-ounce weight per bud is the whole pitch here: they're meant to sit on your ear, not in it, and stay there through running, cycling, yoga or a gym session.
What makes it feel like a complete system is the case. It's a small plastic shell (8 × 6.5 × 2.5 cm, about 50 g) with a 500 mAh battery inside and an LED display that shows you how much charge is left. The earbuds themselves are rated for around 8 hours per charge, and the case extends that to roughly 50 hours total — enough for a week of workouts between trips to a USB-C cable. Battery recharge time is about an hour, which is quick. Bluetooth 5.4 handles the connection with a 10-meter range and a very low stated latency, which matters if you're watching video on a treadmill. Dual built-in microphones handle calls, and touch controls sit on the buds themselves.
Potewek Bone Conduction Headphones: Who It's For
The Potewek Bone Conduction Headphones take the opposite approach: one continuous neckband instead of two separate buds. There's no case, no pairing dance, nothing to lose in a gym bag. At roughly 25g in a titanium and liquid-silicone frame, it's the kind of headset you drape around your neck and forget about until you need it.
The headline feature is the built-in 32GB MP3 player. That's a genuinely different proposition from almost any earbud: you load your music onto the headset itself and run, ride or lift without your phone anywhere near you. For anyone who's tired of a phone bouncing in a pocket or strapped to an armband, that alone changes the workout. Alongside it, Potewek combines bone conduction with air conduction in a hybrid driver setup, which is intended to give you more low-end body than bone conduction alone while keeping your ears completely open.
The second big differentiator is IP68 waterproofing. Sweat, rain, splashes — this is the headset you don't have to baby, and it's the one I'd point a cyclist or a trail runner toward on a wet day. It also lists adaptive noise cancellation, which is unusual on an open-ear design and mostly useful for pulling down steady background hum on calls or in a noisy gym. Bluetooth 6.0 is the newer wireless standard here, with the same 10-meter range. The trade-offs are honest ones: about 10 hours of playback per charge and roughly 3 hours to recharge — slower and shorter per-session than the JIMBOBO buds, though there's no case to forget. There's also no headphone jack, so it's Bluetooth or the built-in storage, nothing else.
Who should buy it: runners, cyclists, swimmers-adjacent athletes and anyone who wants offline music without a phone. Who should skip it: people who prefer two independent earbuds they can use one at a time, and anyone who wants a compact charging case for travel.
Side-by-Side: Which Should You Choose?
• Best for total battery life → JIMBOBO Open Ear Headphone. The charging case pushes total playtime to around 50 hours versus Potewek's roughly 10 hours per charge.
• Best for sweat and rain → Potewek Bone Conduction Headphones. IP68 is a real rating; JIMBOBO doesn't list water resistance at all.
• Best for calls and everyday earbud habits → JIMBOBO Open Ear Headphone. Dual mics, touch controls, a case with an LED battery readout and one-hour charging make it the more convenient daily pair.
• Best for glasses-wearers and hat-wearers → Potewek Bone Conduction Headphones. A neckband sits behind the head rather than hooked over the ear, so there's less to interfere with temples or a cap.
• Best for low-latency video and gaming → JIMBOBO Open Ear Headphone. Its stated latency is extremely low, which suits treadmill screens and phone video.
• Best for comfort over long sessions → Potewek Bone Conduction Headphones. At 25g with a titanium band and no in-ear contact, it's built for hours of continuous wear.
• Best for people who lose small things → Potewek Bone Conduction Headphones. One piece, no charging case to misplace.
In my opinion, most people should buy the Potewek Bone Conduction Headphones. The 32GB built-in player, IP68 waterproofing and hybrid drivers solve the two problems that actually ruin open-ear headphones for athletes — a phone you have to carry and sweat that kills the electronics. The shorter battery life and slower charging are real, but for a runner or gym-goer they're a fair trade.
I'd still recommend the JIMBOBO Open Ear Headphone to anyone who lives in earbuds: calls all day, a case in the pocket, an LED readout that tells you what's left, and 50 hours before you think about a cable. If you want normal earbud behaviour with open ears, that's your pick.
FAQ
Yes — that's their standout feature. They hold 32GB of music internally, so you can run with nothing but the headset. The JIMBOBO earbuds are Bluetooth-only and always need a paired device.
Per session, the JIMBOBO earbuds are rated around 8 hours, but the charging case extends total listening to roughly 50 hours. The Potewek headset is rated around 10 hours per charge with no case, so it wins per session but loses on total capacity.
Potewek lists adaptive noise cancellation. JIMBOBO lists noise control as none. Either way, both are open-ear designs, so you'll still hear your surroundings — that's the point.
The JIMBOBO Open Ear Headphone, in my opinion. Dual built-in microphones, touch controls and a case with a visible battery readout make it the more practical everyday pair for calls.
