• Raycon Fitness Open Ear — biggest strength: 40 hours of total battery life (8 hours per charge plus 32 more from the charging case), a rotating multi-axis ear hook, and Bluetooth 5.2 with multipoint connection.
• Raycon Fitness Open Ear — biggest trade-off: It's a traditional open-ear air-conduction design, not bone conduction, and the per-charge runtime is 8 hours, so heavy users will lean on the case.
• Pupabiflor Bone Conduction Headphones — biggest strength: A true bone conduction driver with an IPX7 waterproof rating, 12 hours of continuous playtime, and a 29g titanium-alloy memory-wire frame.
• Pupabiflor Bone Conduction Headphones — biggest trade-off: No charging case, no multipoint pairing, and a single 12-hour charge is the ceiling — great for one long session, less flexible across a full week.
• Who each is for: Raycon for gym-goers and commuters who want a case, multipoint switching, and the longest total runtime. Pupabiflor for runners and cyclists who sweat hard, get caught in rain, and want the lightest possible frame.
The Raycon Fitness Open Ear is built around flexibility and stamina. The headline number is 40 hours of total battery life, but the way it's split matters: 8 hours of nonstop sound per charge, plus another 32 hours stored in the charging case. That case is the real differentiator here — it fits in a hand or pocket, so you can top up between sessions instead of hunting for a wall outlet. For anyone who trains in the morning and takes calls in the afternoon, that's a genuinely useful buffer.
The fit system is the other standout. Raycon uses multi-angular hooks behind the ear with two rotational axes, which means you adjust the hook position rather than hoping a fixed shape matches your ear. In my opinion, that adjustability is what makes these worth a look for lifting, stretching, and treadmill work, where a fixed hook can shift as you move your head. The open design keeps your ears unobstructed, so you stay aware of traffic, gym noise, and whatever's happening around you. Bluetooth 5.2 with multipoint connection lets you pair multiple devices at once and switch instantly — start a workout playlist on your phone, then jump to a work call on your laptop. Digital Signal Processing amplifies your voice and reduces background noise on calls. Sweat resistance is included, and the drivers cover a 20 Hz to 20,000 Hz frequency range with a dynamic driver. A one-year warranty rounds it out.
Who should buy it: commuters, gym regulars, and hybrid workers who move between devices and want a case-backed battery buffer. Who should skip it: swimmers, or anyone who needs a formal waterproof rating — the sheet lists sweat resistance, not an IPX7 claim, and there's no jack, so it's Bluetooth-only.
The Pupabiflor set takes the opposite approach: strip weight, add durability. At 29g with an integrated frame and a precision titanium alloy memory wire, this is a frame that adapts to your ear shape rather than clamping onto it. The bionic-based earhook grips multidimensionally, which is the design language for "stays put when you're bouncing down a trail." If you've ever had a hook pop loose mid-stride, that spec is the one to care about.
The IPX7 rating is the real story. Nano-coating plus IPX7 means these are rated to handle rain and heavy sweat, not just a light misting. For runners in humid climates or anyone doing high-intensity intervals indoors, that's the difference between a product you baby and one you just wear. Bone conduction drivers transmit sound through your cheekbones and leave your ear canal completely open, so external sound enters unobstructed — the safety case for jogging, cycling, and trail work writes itself.
Battery is 12 hours of continuous use from a high-density battery, with no case in the box. Bluetooth 5.3 handles pairing with phones, tablets, and computers with low latency. Included is a user manual; the frame is Pure Black in a silicone and titanium alloy enclosure. There's no noise control and no multipoint — this is a single-device, single-session tool.
Who should buy it: outdoor runners, cyclists, and trail users who prioritize waterproofing and light weight over accessories. Who should skip it: anyone who wants a case, multipoint switching, or more than 12 hours between charges.
• Best total battery life → Raycon Fitness Open Ear: 40 hours combined (8 per charge + 32 in the case) versus 12 hours total on the Pupabiflor.
• Best per-session runtime without a case → Pupabiflor Bone Conduction Headphones: 12 hours continuous in one go, no recharging mid-day.
• Best for rain and heavy sweat → Pupabiflor: IPX7 with nano-coating, versus Raycon's sweat-resistant (unrated) construction.
• Lightest, most adaptive frame → Pupabiflor: 29g with titanium alloy memory wire and a multidimensional earhook.
• Best fit adjustability for varied workouts → Raycon: multi-angular hooks with two rotational axes you position yourself.
• Best for switching between phone and laptop → Raycon: Bluetooth 5.2 with multipoint connection; Pupabiflor is Bluetooth 5.3 but single-device.
• Best for situational awareness while running outdoors → either, but Pupabiflor leans harder into it: bone conduction leaves the ear canal fully open, and Raycon's open design does the same with air-conduction drivers.
• Best for call quality on the move → Raycon: Digital Signal Processing amplifies your voice and cuts background noise.
• Best for people who hate charging cases → Pupabiflor: nothing extra to carry or lose.
My Verdict
I'd buy the Raycon Fitness Open Ear for most people. In my opinion, the combination of 40 hours of case-backed battery, multipoint switching, and adjustable rotating hooks makes it the more versatile everyday pick — it covers runs, gym sessions, commutes, and work calls without you thinking about it. The Pupabiflor is the better specialist: if your priority is IPX7 waterproofing, a 29g frame, and pure outdoor awareness, that's the one I'd hand a dedicated trail runner. But as a single do-everything pair, Raycon wins on flexibility.
how to run with earbuds
The main thing is fit security and awareness. Both of these are open designs that leave your ear canal unobstructed, so you hear traffic and surroundings while you run. Raycon uses multi-angular hooks with two rotational axes you adjust behind the ear; Pupabiflor uses a 29g memory-wire frame with a multidimensional earhook. Position the hook first, then check it stays put through a few strides before you commit to a full run.
how to run with wired earbuds
Neither of these is wired — both are Bluetooth-only with no headphone jack. If you're specifically asking about wired running earbuds, that's a different category, and the cable management and snag risk are the usual trade-offs. If you want the freedom of movement these two offer, you'll be pairing over Bluetooth: Raycon on 5.2 with multipoint, Pupabiflor on 5.3 for low-latency pairing.

That's a different brand with its own pairing routine, so I can't give you steps for it here. For the two products on this page: both pair over standard Bluetooth with no jack involved. Raycon adds multipoint so you can connect multiple devices and switch instantly; Pupabiflor connects to phones, tablets, and computers one at a time on Bluetooth 5.3.

Again, that's another brand's process, and pairing steps vary by model. What I can tell you is how these two differ in connectivity: Raycon's Bluetooth 5.2 supports multipoint, meaning two devices at once with instant switching — handy if you move from a phone playlist to a laptop call. Pupabiflor's Bluetooth 5.3 is single-device but pairs quickly with phones, tablets, and computers.
