If you want an open-ear, bone-conduction design that keeps your ears free and your surroundings audible while you run, choose Cevinily 2025; if you need sealed in-ear buds with huge battery life, a charging case and a higher waterproof rating, choose HAOYUYAN Earbuds.
These two look like they belong in the same "sports earbuds" bucket, but they solve completely different problems. One lets the world in on purpose. The other shuts the world out and keeps going for days. Here's how I'd sort them out.
• Cevinily 2025's biggest strength: bone-conduction, open-ear design — nothing goes inside your ear canal, so you stay aware of traffic, other runners and your surroundings while listening.
• Cevinily 2025's biggest trade-off: open-ear sound leaks and bass is lighter than sealed earbuds, and IPX5 only covers sweat and light rain — not submersion.
• HAOYUYAN Earbuds' biggest strength: massive battery life — up to 80 hours total with the charging case, 15 hours per earbud on a single charge, plus a dual LED power display.
• HAOYUYAN Earbuds' biggest trade-off: they're in-ear buds with ear hooks, so you're sealed off from your environment, and the warranty is only 90 days versus Cevinily's 1 year.
• Choose Cevinily 2025 if you run, walk or cycle outdoors and want to hear what's happening around you.
• Choose HAOYUYAN Earbuds if you want long, uninterrupted listening sessions and don't mind blocking out ambient sound.
The Cevinily 2025 is a bone-conduction, open-ear headphone. Instead of pushing a tip into your ear canal, it sits outside your ear and transmits sound through your cheekbones to your inner ear. That's the whole point of the design, and it changes how you use it. You can hear your music and still hear a car approaching, a cyclist calling out, or a training partner talking to you. For outdoor runners and cyclists, that awareness is the feature, not a bonus.
Who should buy it: runners, walkers, cyclists, hikers, and anyone who wants music without plugging their ears. Controls are physical push buttons, which I actually prefer during sweaty workouts — no touch misreads. It ships with a cable, eartip and manual, and carries a 1-year warranty.
Who should skip it: if you want deep, thumping bass in a quiet room, or you want to fully block out a noisy commute, an open-ear design is the wrong tool. Also skip it if you need real waterproofing — IPX5 handles sweat and light rain, not swimming or heavy downpours.
HAOYUYAN Earbuds: Who It's For
The HAOYUYAN Earbuds (model BX17) go the opposite direction. These are true in-ear buds with flexible ear hooks and three sizes of silicone tips, so you get a secure, personalized fit that stays locked in during hard training. Because they seal your ear canal, they isolate you from the world — and that's the appeal if you're at a desk, on a plane, or in a gym where you'd rather not hear the room.
Battery is the headline. Up to 80 hours of total listening time, with each earbud lasting 15 hours on a single charge and the case providing roughly 8 full recharges. A dual digital power display shows remaining battery whenever you open or close the case, so you're not guessing. That combination makes them a genuinely good pick for travel, long workdays and multi-day trips where you don't want to think about charging.
Who should buy it: commuters, travelers, gym-goers, and anyone who wants long battery life and sealed, bass-forward sound. Who should skip it: if you need to stay aware of traffic while running outdoors, the sealed fit works against you. And note the warranty is only 90 days, shorter than Cevinily's year.
Side-by-Side: Which Should You Choose?
• Best for outdoor safety and awareness → Cevinily 2025. Open-ear bone conduction keeps your ears free.
• Best for battery life → HAOYUYAN Earbuds. Up to 80 hours total versus 12 hours on the Cevinily.
• Best for bass and isolation → HAOYUYAN Earbuds. Sealed tips plus 14.3mm dynamic drivers.
• Best for the newest Bluetooth → Cevinily 2025. Bluetooth 5.4 beats the HAOYUYAN's 5.3.
• Best for water resistance → HAOYUYAN Earbuds. IPX7 (submersion-rated) versus IPX5 (sweat and light rain).
• Best for long-term peace of mind → Cevinily 2025. A 1-year warranty versus 90 days.
• Best for all-day comfort without ear fatigue → Cevinily 2025. Nothing sits inside your ear canal.
• Best for commuting and travel → HAOYUYAN Earbuds. The case, LED display and 80-hour total make them effortless to live with.
If I had to pick one for myself, I'd take the HAOYUYAN Earbuds. The battery math is the deciding factor for me — 15 hours per bud and roughly 80 hours with the case means I'd rarely think about charging, and IPX7 gives real confidence in rain and sweat. In my opinion, the sealed fit and bigger drivers also deliver more satisfying sound for everyday listening, work and travel. The shorter 90-day warranty is the one thing that gives me pause. If your priority is hearing traffic while you run, go the other way and get the Cevinily 2025 — its open-ear design and 1-year warranty make it the smarter outdoor pick.
FAQ
HAOYUYAN by a wide margin. It's rated up to 80 hours total with the charging case and 15 hours per earbud on a single charge, versus up to 12 hours of continuous use on the Cevinily 2025.
Yes — they're rated IPX7, meaning protection against sweat, rain and accidental submersion up to 1 meter for 30 minutes. The Cevinily 2025 is IPX5, which covers sweat and light rain but not submersion.
