If you want a tiny, lightweight in-ear bud that disappears into small ears and still survives sweat and rain, choose Obbug True; if you need a secure ear-hook fit with longer single-charge playback and a bigger bass driver, choose WAVEFUN Headphones.
• Obbug True — biggest strength: genuinely mini earbuds built for small ears, with IPX7 sweat/rain protection and a charging case that tops the buds up multiple times.
• Obbug True — biggest trade-off: the charging case itself is not waterproof, and per-charge playtime is modest next to the WAVEFUN.
• WAVEFUN Headphones — biggest strength: an ear-hook design that stays put during hard workouts, plus up to 15 hours of music time on a single charge and an 11mm driver for bass.
• WAVEFUN Headphones — biggest trade-off: bulkier on the ear, and it leans on a hook rather than a low-profile in-ear fit, so it's less discreet.
• Buy Obbug True if you have small ear canals, want a barely-there bud, and mostly train in sweaty or rainy conditions.
• Buy WAVEFUN Headphones if you run, hike or lift hard, want the buds locked in place, and hate recharging mid-week.
The Obbug True is all about size. These are true wireless in-ear buds described as mini and comfortable, with a rounded-tip shape and a secure fit that the spec sheet says suits "all shapes of ears." If standard earbuds tend to pop out or feel like they're stretching your canal, that small form factor is the whole point here. The earpieces are plastic, the color is pink/rose gold, and they land at roughly 18 grams — light enough that you'll forget they're in.
Protection is where the Obbug earns its keep for training. It carries an IPX7 waterproof rating, achieved with a nano coating, and the brand explicitly frames it as protection from heavy rain and sweat during intense workouts. One caveat straight from the data: the charging case is not waterproof. So the buds can take a downpour; the case should stay in a dry pocket or bag.
On the tech side you get Bluetooth 5.1 with instant pairing, auto-reconnect, and a stable connection quoted up to about 12 meters (the general spec lists a 10-meter Bluetooth range). Battery is a 600mAh lithium-polymer cell giving roughly 5 hours of talk/play time and up to 120 hours standby, with a 1–2 hour full charge. The portable case holds enough for 2–3 extra full charges, and the brand totals it at around 18 hours from the case and roughly 22 hours of combined playback. Controls are touch-based via the MFB area in the center of each bud — single press for play/pause and calls, triple press to skip tracks, long press for volume. Noise control is sound isolation, and it's broadly compatible with iPhone, Samsung Galaxy, iPad, and most Bluetooth devices. It ships with the buds, case, a Type-C cable, four ear tips, and a manual.
Buy it if you want a low-profile bud for small ears, value IPX7 sweat/rain resistance, and can live with around 5 hours per charge. Skip it if you want one long marathon charge, need the case to survive water, or prefer a physical button over touch.
The WAVEFUN XBuds take the opposite approach: instead of hiding in your ear, they hook over it. The design uses silicone ear hooks in a black-and-grey finish, and the brand's whole pitch is "stay in ear" security for running, jogging, hiking, biking, and gym work. If you've ever had a bud launch itself onto the treadmill, this is the fix — the hook physically anchors the earpiece so it doesn't rely on canal pressure alone.
It also matches the Obbug on water resistance: the WAVEFUN carries an IPX7 waterproof rating too, built from a highly sealed shell plus nano-coating, and it's marketed as unfazed by heavy sweat during strenuous training. That makes both of these genuinely rain-and-sweat-capable earbuds.
Where the WAVEFUN pulls ahead is endurance and low-end. It uses an 11mm dynamic driver — a notably large speaker for an earbud — paired with Bluetooth 5.3, AAC audio transmission, and an ATS3015 chip, tuned for clear, loud sound with "super bass." The battery is a 120mAh cell delivering up to 15 hours of music time per charge, with a full charge in about 2 hours and a charge-light indicator. It also pushes battery status to your phone's screen on iOS or Android, which is handy mid-run.
Latency is quoted at 45 milliseconds, which matters if you watch video or game and don't want audio drifting out of sync. Controls are physical push buttons (play/pause, skip, volume) rather than touch — a real plus with sweaty or gloved hands. Connectivity is Bluetooth-only (no jack), range is about 10 meters, and it works with Android, iOS, and other Bluetooth devices. In the box: the X-Buds, a carry bag/case, charging cable, XS/S/M/L ear tips, a hanging buckle, and a manual. The impedance is 16 ohm, frequency range 20Hz–20kHz, and the warranty is listed at one year.
Buy it if you want buds that stay locked in during hard movement, need long single-charge playtime, and like real buttons. Skip it if you want a discreet, near-invisible fit or prefer touch controls.
• Best for small ears → Obbug True. It's explicitly built mini for small canals; the WAVEFUN relies on hooks for security.
• Best for long single-charge playback → WAVEFUN Headphones. Up to 15 hours versus about 5 hours per charge on the Obbug.
• Best for total playtime with a case → Obbug True. Its 600mAh case adds 2–3 full recharges, roughly 22 hours combined.
• Best for bass and loudness → WAVEFUN Headphones. An 11mm driver is the bigger speaker of the two.
• Best for low audio lag → WAVEFUN Headphones. It quotes 45ms latency; the Obbug doesn't list a figure.
• Best for a discreet, barely-there fit → Obbug True. No hook, tiny housing, sound-isolating in-ear seal.
• Best for sweaty or rainy training → both. Each is IPX7-rated; just keep the Obbug's case dry since only the buds are waterproof.
• Best for physical controls → WAVEFUN Headphones. Push buttons beat touch when your hands are wet.
In my opinion, I'd buy the WAVEFUN Headphones for most people training outdoors. The ear-hook fit solves the single most annoying earbud problem — buds falling out mid-workout — and up to 15 hours per charge plus 45ms latency makes it the more forgiving daily driver. I'd pick the Obbug True instead if small ears are your priority and you want a truly low-profile bud with a case that keeps you topped up all day. Both handle IPX7 sweat and rain, so the deciding factors are fit style, per-charge battery, and driver size. Check the current price on Amazon before you commit.
are ipx7 earbuds waterproof
IPX7 is a waterproof rating, not just water-resistant. Both the Obbug True and WAVEFUN XBuds are rated IPX7 for their earbuds, meaning they're designed to shrug off sweat and heavy rain. Note the Obbug's charging case is not waterproof, so keep it dry.
can you shower with ipx7 earbuds
IPX7 means the earbuds are built to handle water immersion, and both models here are rated for heavy sweat and rain during workouts. That said, the brands describe them for training and all-weather use, not showering — and the Obbug's case isn't waterproof, so I wouldn't take it into the bathroom.
Per charge, the WAVEFUN wins with up to 15 hours of music time versus roughly 5 hours for the Obbug. Over a full day, the Obbug's 600mAh case adds 2–3 recharges (about 22 hours combined), so it's a closer contest if you carry the case.
The WAVEFUN is designed specifically for that, using silicone ear hooks to lock each bud in place for running, hiking, and gym work. The Obbug relies on a mini in-ear fit the brand describes as secure for all ear shapes — good, but without a hook.
