• BKIBD Open Ear Headphones — biggest strength: True open-ear, bone-conduction-style earbuds with a charging case, dual-mic ENC calling and an ultra-light 8 g per earbud build.
• BKIBD Open Ear Headphones — biggest trade-off: Battery life tops out around 7 hours of playback, and the brand itself advises against using ANC mode while listening to music.
• BIGFOX Motorcycle — biggest strength: A 1000 mAh battery rated for roughly 32 hours of playtime and up to 360 hours of standby, with a boom mic and a 10 mm-thin speaker that fits inside a helmet.
• BIGFOX Motorcycle — biggest trade-off: It is not a standalone pair of headphones — it needs a helmet, a mount and installation to be useful at all.
• Who each pick is for: BKIBD for runners, gym-goers, cyclists and anyone who wants to hear traffic while listening. BIGFOX for riders, skiers and helmet wearers who want audio and calls inside the helmet.
The BKIBD Y312 Pro is built around one idea: keep your ears open. Instead of plugging your ear canal, the drivers rest against your cheekbones and send sound toward your inner ear, similar in concept to bone conduction headphones. In practice that means you stay aware of your surroundings — traffic, other runners, a gym announcement — while your music keeps playing. For outdoor training, that awareness is the whole point, and it is the main reason people move to open-ear designs in the first place.
The physical package backs that up. Each earbud weighs just 8 grams and the charging case adds 48 grams, so the whole kit disappears into a pocket or a small bag. IPX6 waterproofing covers sweat and splashes, which is exactly the abuse a running or workout headphone takes. Bluetooth 5.4 handles the connection, and dual-microphone ENC is there to keep your voice clear on calls in noisy places — useful for casual chats and the occasional work call. The frequency range is listed at 20 Hz to 20,000 Hz, so you are getting a full-range driver on paper, with the brand promising rich bass and clear highs.
Two honest caveats. First, playback is rated at up to 7 hours of music or 6 hours of talk, and the charging case is what keeps you going beyond that — fine for daily sessions, less ideal for marathon-length listening. Second, and more important, the manufacturer explicitly recommends not turning on ANC mode while listening to music, warning that it can produce a harsh sound when you adjust the headphones. That is unusual, and it tells you the ANC here is better treated as a situational feature than a always-on one. Buy these for the open-ear fit, the light weight and the calling clarity — not for noise cancellation.
Who should skip it: anyone who wants deep isolation, long single-charge battery life, or a headset that lives inside a helmet. This is a body-worn earbud, not a helmet system.
The BIGFOX Y10 is a different animal entirely. It is a helmet Bluetooth headset: a small host unit, a speaker and microphone assembly, a clip-on base and adhesive, all designed to be installed inside a motorcycle helmet. The speaker is only 10 mm thick, which is the spec that matters most here — it is thin enough that it should not press against your ears inside the helmet, and the brand states it fits all helmets. If you have ever tried to cram a normal earbud under a helmet, you already understand why that number matters.
Battery is where the Y10 runs away from typical earbuds. A 1000 mAh cell is rated for about 32 hours of continuous working time and up to 360 hours of standby, with a charge time of roughly 2.5 hours over USB-C. There is also battery-level display on your phone, which is genuinely handy on a multi-day trip. For a rider, that combination means you charge it occasionally rather than constantly, and you are not babysitting a percentage indicator every time you gear up.
Feature-wise, it runs Bluetooth 5.3 with a claimed 20 m transmission range in open space, and it can connect two smartphones at once — so navigation from one phone and calls or music from another can coexist. There is intelligent noise cancellation, a voice assistant button you can press to wake Siri or another assistant without looking down, and the controls are designed to be usable with gloves. IPX6 waterproofing covers rain, dust, snow and cold-weather riding, which is the realistic range of conditions a rider meets. It ships with two microphone types, the host unit, the mounting hardware and a manual. BIGFOX also lists a 2-year manufacturer warranty.
The trade-off is obvious: none of this works without a helmet and a bit of installation. The 60 g unit is not something you wear around the house, and the 85 mm × 35 mm host needs a spot on your helmet. Buy it as riding gear, not as general-purpose headphones.
Side-by-Side: Which Should You Choose?
• Best for running and gym workouts → BKIBD Open Ear Headphones. Open-ear fit, 8 g per bud, IPX6, and you keep your awareness of what's around you.

• Best for all-day carry and portability → BKIBD Open Ear Headphones. Earbuds plus a 48 g case slip into any pocket; the BIGFOX needs your helmet.
• Best for calls in noisy environments → BKIBD Open Ear Headphones. Dual-mic ENC is aimed squarely at voice clarity on the move.
• Best for hands-free voice commands while occupied → BIGFOX Motorcycle. A single button wakes your assistant without taking your attention off the road.
• Best for winter sports and harsh weather → BIGFOX Motorcycle. IPX6 plus a design that tolerates dust, rain, snow and low temperatures, and it lists skiing among its uses.
• Best for someone who wants to hear traffic while listening → BKIBD Open Ear Headphones. Open-ear audio is the safer default for street running and cycling.
I would buy the BKIBD Open Ear Headphones if my listening happens on my own two feet — runs, gym sessions, walks, commutes where I want to stay aware of traffic. It is lighter, more portable, and the open-ear design is the feature you actually feel every day. I would buy the BIGFOX Motorcycle without hesitation if I ride. The 32-hour battery, the helmet-ready 10 mm speaker, the dual-phone pairing and the glove-friendly voice button are exactly what a rider needs, and no pair of earbuds substitutes for that. In my opinion, the right answer comes down to one question: are you wearing a helmet or a pair of running shoes?
