• YLYHHFY Clip – biggest strength: an open-ear clip-on design at roughly 3.5 grams per bud, with a charging case that pushes total listening time to about 30–32 hours and shows the battery level on a digital display.
• YLYHHFY Clip – biggest trade-off: the buds themselves only run about 4–5 hours per charge, and the touch controls take some getting used to, especially with sweaty or gloved fingers.
• XPAU Bone Conduction Headphones – biggest strength: a true bone conduction build with dual ENC microphones, IPX6 sweat-and-rain protection, and physical buttons you can operate blind.
• XPAU Bone Conduction Headphones – biggest trade-off: it's a single-piece headset at 27 grams with no charging case, so you're capped at the built-in battery and you have to remember to top it up via Type-C.
• Who each is for: pick the YLYHHFY Clip if you want light, pocketable buds for the gym, work and calls; pick the XPAU if you run or cycle near traffic and want your ears fully open with tactile controls.
The YLYHHFY Clip is a clip-on open-ear earbud, and its whole identity is lightness. At about 3.5 grams per earbud, the design leans on a multi-point support system that spreads the weight around your ear instead of pressing into the canal. The clip shape also lets you adjust the angle and curvature, so you're not stuck with one fixed fit. For anyone who hates the "plugged" feeling of traditional buds but still wants stereo sound with real bass, that combination is the appeal.
On the tech side, it runs Bluetooth 5.4 with antenna tuning for a stable connection, pairs automatically when you lift the buds out of the case, and reconnects to the last device. There's active noise cancellation for calls, touch controls for playback and hands-free calling, and a nano coating that protects both the buds and the case from sweat, rain and splashes. The dynamic driver handles the audio, and the black electroplated finish with the matching black case keeps it looking tidy.
Battery is where you need to read the numbers carefully. The buds themselves give roughly 4–5 hours, which is fine for a gym session, a commute or a work block. The case adds about 30–32 hours on top, and the digital display tells you exactly how much is left, so you're never guessing. Standby is quoted up to 80 hours, and a full charge takes about 2 hours.
Who should buy it: gym-goers, casual runners, drivers and office workers who want open-ear awareness without a headband, plus anyone who likes the convenience of a case they can drop in a pocket. Who should skip it: marathon-distance athletes who need more than 4–5 hours per session from the buds alone, and people who prefer physical buttons over touch — the touch panel is the part most likely to annoy you mid-workout. It ships with a cable, the charging case and a manual, and carries an 18-month warranty.
The XPAU Bone Conduction Headphones take the opposite approach: instead of tiny buds, it's a single 27-gram open-ear headset that sits on your cheekbones and sends sound through bone conduction. Nothing enters your ear canal at all, which is the entire point. You hear your audio and the world around you at the same time — traffic, a cycling bell, a training partner — without pulling anything out. For runners, cyclists and drivers, that 360° awareness is the feature that matters most.
The hardware backs that up. Bluetooth 5.4 with a 15-meter range, a 15.2 mm bone conduction driver, 32-ohm impedance and a 20 Hz–20 kHz frequency range. Calls go through dual ENC microphones rated at 38 dB sensitivity, which are designed to pull your voice out of wind and gym noise. The ABS frame is IPX6 rated, so torrential rain, sweat and spills are part of the plan rather than a risk. Battery is quoted at up to 20 hours at 50% volume, with Type-C charging taking it from empty to full in under 2 hours.
The controls are the standout detail. Two physical buttons with haptic feedback handle everything: single-tap play/pause, double-tap louder, triple-tap skip, hold to power off, and a hold on the minus button to trigger voice AI. That means no touch panel to misfire when your hands are wet or gloved — a genuinely practical choice for cold-weather running and cycling.
Who should buy it: outdoor athletes, commuters on bikes, people who work out in the rain, and anyone who finds in-ear buds uncomfortable or unhygienic. Who should skip it: anyone who wants a pocketable case and the option to swap between ears, or who mainly listens in loud environments where open-ear audio simply can't compete with isolation. It comes with ear plugs, a storage bag and a manual in eight languages, and carries a 2-year manufacturer warranty.
Side-by-Side: Which Should You Choose?
• Best for total battery with a case → YLYHHFY Clip. Around 30–32 extra hours in the case plus a digital display, versus no case at all on the XPAU.
• Best for running and cycling near traffic → XPAU. Bone conduction leaves your ear canal completely open, and the IPX6 rating handles rain and heavy sweat.
• Best for gym, work and everyday calls → YLYHHFY Clip. Light clip-on buds with ANC for calls, touch control and a case that lives in your pocket.
• Best for wet or gloved hands → XPAU. Physical buttons with haptic feedback beat a touch panel every time your fingers are damp.
• Best for all-day comfort in one spot → YLYHHFY Clip. At 3.5 grams per bud, the weight is barely there, and the clip angle is adjustable.
• Best for call clarity in wind → XPAU. Dual ENC mics at 38 dB sensitivity are purpose-built for noisy outdoor voice pickup.
• Best for charging convenience → YLYHHFY Clip. Drop the buds in the case and they top up; the XPAU needs a Type-C cable every time.
In my opinion, the XPAU Bone Conduction Headphones are the better buy for anyone whose priority is training outdoors safely. Open-ear awareness, IPX6 protection, 20 hours of playtime and glove-friendly physical buttons add up to a headset that's built for movement, not just for wearing. I'd recommend the YLYHHFY Clip instead if you want something pocketable, feather-light and case-charged for the gym, desk and car — but if you're choosing one for running and cycling, I'd go XPAU. Check the current price on Amazon before you commit, since that's the one number I can't give you.
FAQ
Not universally. The YLYHHFY Clip wins on weight (about 3.5 g per bud) and case-backed battery (roughly 30–32 extra hours). The XPAU wins on open-ear safety, IPX6 water protection and physical buttons. It depends on whether you want pocketable buds or a dedicated sports headset.
The XPAU is quoted at up to 20 hours at 50% volume, with a full Type-C charge in under 2 hours. The YLYHHFY buds give about 4–5 hours on their own, plus around 30–32 hours from the charging case, and take roughly 2 hours to charge.
The XPAU. It's IPX6 rated and designed to shrug off heavy rain and sweat, and the open-ear fit plus physical buttons make it the more practical choice when the weather turns. The YLYHHFY Clip has nano-coating protection for sweat and splashes, but its touch controls are harder to use with wet hands.
