If you want a pair of cycling earbuds you can also swim and sweat in without a second thought, choose HIFI WALKER Bone Conduction Headphones; if you need earbuds that stay comfortable and play all day on a single top-up, choose Yistao Open Ear Headphones. That is the short version. The long version comes down to how you actually ride, and that is what I break down below.
• HIFI WALKER Bone Conduction Headphones — biggest strength: a verified IPX8 rating plus a built-in 32GB MP3 player, so it keeps working where water and Bluetooth both stop.
• HIFI WALKER Bone Conduction Headphones — biggest trade-off: bone conduction sends sound through your cheekbones, so bass and isolation are physically limited, and it runs on a modest 8-hour battery.
• Yistao Open Ear Headphones — biggest strength: up to 10 hours per charge and a charging case that stretches total playtime to around 35 hours, in a very light build.
• Yistao Open Ear Headphones — biggest trade-off: IPX6 covers sweat and light rain but not immersion, and there is no onboard storage, so it is always tethered to your phone.
• Pick HIFI WALKER if you ride hard, get caught in rain, and want one pair for cycling, running and the pool.
• Pick Yistao if your rides are dry, your priority is comfort and long battery life, and you always have your phone with you.
The headline feature here is the IPX8 waterproof rating. That is a genuine immersion rating — the sheet describes continuous submersion up to 2 meters, which is a different category from "resists sweat." For cycling specifically, that means rain, road spray, puddles and a post-ride rinse under the tap are all non-events. If you are the kind of rider who does not check the forecast before heading out, that matters.
The second thing that stands out for a cyclist is the 32GB of built-in storage. That turns the T10 Air into a standalone MP3 player holding thousands of songs, and it exists for a real reason: Bluetooth does not travel through water, so the moment you swim, wireless audio stops. You switch to MP3 mode with the tactile buttons and the music keeps going. On the bike it is less critical, but it is genuinely useful if you want to leave the phone at home on a short training loop and carry nothing but headphones.
There is also the open-ear design, which routes audio through your cheekbones and leaves your ear canals completely open. On a bike that is a safety feature, not a compromise — you can hear traffic, a bell behind you, or a riding partner without pulling an earbud out. The adjustable tension band is there to keep the fit stable and bounce-free, and HIFI WALKER adds a swimming mode lock so you do not accidentally change tracks mid-stroke. Battery life is 8 hours with a 2-hour charge time, and the driver is a bone conduction unit covering 20 Hz to 20,000 Hz.
Who should skip it? Anyone who mostly wants deep, punchy bass while riding. Bone conduction drivers trade low-end weight for that open-ear awareness, and no amount of tuning fully closes that gap. If your rides are short, dry commutes and you want sealed, fuller sound, this is not the tool. Also skip it if 8 hours feels tight for multi-day touring without a charger.
Yistao takes the opposite approach: it optimizes for comfort and endurance rather than water and independence. Each earbud weighs 0.26oz, and the frame is a 0.7mm titanium alloy with soft silicone cushions that flex to your ear shape. The earpiece is a hook design, so it hangs over the ear instead of pressing into the canal. For long rides, that lightness is the whole point — you are far less likely to feel pressure or soreness at hour three than with a heavier set.
Battery is the other headline. Yistao rates 10 hours of music per charge, and the charging case takes total playtime to about 35 hours. That is a serious advantage for cyclists who ride several times a week and hate remembering to plug things in. The case itself is a pocketable 3.54 x 2.68 x 0.91 inches and weighs 59g, so it travels easily.
On the audio side, Yistao uses a 16mm dynamic driver with 110dB sensitivity and 16 ohm impedance, and the spec sheet claims AreoDirect to limit sound leakage and AreoBoost to lift vocals. Bluetooth 5.3 handles the connection with a claimed 60ms latency, which keeps audio and video reasonably in sync. The IPX6 rating is backed by a hydrophobic coating on the mic and speaker grilles plus a double-layer nanocoating — enough for sweat and light rain, but not for immersion.
Who should skip it? Swimmers, and anyone who routinely rides through heavy rain or wants a phone-free setup. IPX6 is a splash-and-sweat rating, and there is no internal storage, so the Yistao is only as good as the phone in your pocket. If you want one pair that covers the pool and the road, this is not it.
• Best for water and heavy rain → HIFI WALKER Bone Conduction Headphones. IPX8 with submersion to 2 meters versus IPX6 splash resistance.
• Best for all-day battery → Yistao Open Ear Headphones. 10 hours per charge and roughly 35 hours with the case, against 8 hours on the HIFI WALKER.
• Best for phone-free rides → HIFI WALKER Bone Conduction Headphones. The 32GB MP3 mode needs no phone at all.
• Best for long-ride comfort → Yistao Open Ear Headphones. 0.26oz per bud on a titanium-alloy hook frame is about as light as open-ear gets.
• Best for cyclist safety and awareness → HIFI WALKER Bone Conduction Headphones. Bone conduction through the cheekbones leaves the ear canal fully open; the Yistao is open-ear too, but it hooks over the ear.
• Best for bass and fuller sound → Yistao Open Ear Headphones. A 16mm dynamic driver will generally deliver more low-end weight than a bone conduction transducer.
• Best for a do-everything training pair → HIFI WALKER Bone Conduction Headphones. Cycling, running and swimming in one set.
• Best for casual, dry-weather riders → Yistao Open Ear Headphones. Light, comfortable, and the case means you rarely think about charging.
For cycling earbuds, I would buy the HIFI WALKER Bone Conduction Headphones. In my opinion, the IPX8 rating and the 32GB MP3 mode are the two features that actually change how you use a headphone on a bike — rain stops being a problem, and the phone stops being mandatory. The 8-hour battery is the honest weak point, and if that is a dealbreaker for you, the Yistao's 35 hours with the case is a real argument in its favor. But for a pair that survives everything a cyclist throws at it, HIFI WALKER wins my pick.
Both are open designs that keep your ears free so you can hear traffic. In my opinion the HIFI WALKER has the edge for cycling because its IPX8 rating handles rain and spray far better than the Yistao's IPX6.
Yes, in this case. The HIFI WALKER is rated IPX8 for continuous immersion up to 2 meters. Note that Bluetooth does not transmit through water, so you switch to the built-in 32GB MP3 mode while swimming.
The HIFI WALKER runs about 8 hours with a 2-hour charge time. The Yistao runs about 10 hours per charge, and its charging case extends total playtime to roughly 35 hours.
Both vary by seller, so check the current price on Amazon before deciding. Let your riding conditions pick the winner: wet and rugged favors HIFI WALKER, light and long-lasting favors Yistao.
