If you want the longer total battery reserve, newer Bluetooth and a higher waterproof rating, choose sprtoybat Earbuds; if you need true physical buttons and the longest single-charge listening time, choose occiam Sport. That's the whole decision in one line, and everything below explains why I land there.
• sprtoybat Earbuds — biggest strength: a 68-hour total playtime figure backed by an 800 mAh case, Bluetooth 5.4, IPX7 waterproofing and 14.2 mm graphene drivers.
• sprtoybat Earbuds — biggest trade-off: touch controls only, and "noise cancelling" here means a passive seal plus an ENC mic, not active noise cancellation.
• occiam Sport — biggest strength: dedicated volume + / − buttons on each bud with tactile feedback, and 10 hours of playback per single charge.
• occiam Sport — biggest trade-off: older Bluetooth 5, a shorter 10 m range, and IPX5 rather than IPX7 water protection.
• Who each is for: sprtoybat for long-week battery peace of mind and wet-weather outdoor work; occiam Sport for anyone who hates touch controls and wants to leave the phone alone.
The sprtoybat Q38 is built around one idea: you should almost never think about charging. Each bud runs up to 8 hours, and the case adds 8 to 9 more top-ups for a claimed 68 hours total. The case itself is an 800 mAh cell that refills over Type-C in about 2 hours, and a 10-minute top-up is quoted as good for roughly 2 hours of music. If you're the kind of person who charges on Sunday night and then forgets about it, that math is the whole appeal.
On the audio side you're getting 14.2 mm dual-layer graphene dynamic drivers with a 20 Hz–20,000 Hz range, 80 ohm impedance and 38 dB sensitivity. Big drivers like these usually mean bass you can feel rather than just hear, which suits gym playlists and podcasts with a lot of low-end rumble. The mic side is handled by an ENC array that's quoted as cutting background noise by around 75% — worth knowing if you take calls from a windy track or a busy street.
Fit and durability are where this one pulls ahead for outdoor use. Flexible TPU ear hooks plus three sizes of silicone tips (S/M/L, with extras in the box) give you a hook-over-ear design that resists slipping. IPX7 is the notable spec: that's protection against immersion, not just splashes, so heavy sweat and real rain are comfortably inside its comfort zone. Controls are touch-only on the bud surface, and pairing covers iOS, Android, laptops and tablets with auto-reconnect after the first link.
Who should skip it? If you've ever cursed a touch sensor that paused your music when you adjusted your hood, this isn't your bud. There's no active noise cancellation either — just a passive seal and the ENC mic, so it won't silence a plane cabin or a loud train. And the gold-pink finish is a deliberate look, not a neutral one.
The occiam T17 takes the opposite approach to control. Every bud carries its own volume + and − buttons plus a multifunction button, and the feedback is tactile — you press, you feel it click, you know it worked. Volume, play/pause, track skip, calls and voice assistant all happen without looking at anything. For runners, cyclists and anyone wearing gloves in winter, that's not a small detail. It's the reason to buy this pair.
Battery strategy is different too. occiam quotes 10 hours per bud on a single charge, 48 hours if you run both earbuds together through the case, and up to 80 hours total if you rotate between the two buds. Type-C fast charging brings them back in about 1.5 hours. So while the case reserve is smaller than sprtoybat's, the per-charge endurance is longer — genuinely useful for a long hike, a shift at work, or a day of travel where you'd rather not dock them mid-way.
Comfort is the other headline. Each bud weighs about 8 grams, with soft silicone ergonomic hooks shaped to sit in the ear for hours. The sound side uses a 10 mm bio-diaphragm dynamic driver with a 20 Hz–20,000 Hz range, 32 ohm impedance, 88 dB sensitivity and a quoted 88 ms latency. That low impedance makes them easy to drive from a phone. The mic uses environmental noise cancellation for calls, and pairing is automatic once you lift them out of the case, across iOS, Android and Windows.
Side-by-Side: Which Should You Choose?
• Best total battery reserve → sprtoybat Earbuds. 68 hours total from an 800 mAh case beats a 48-hour dual-ear figure, even though occiam wins on a single charge.
• Best single-charge endurance → occiam Sport. 10 hours per bud is longer than sprtoybat's 8, and rotating buds stretches it to 80 hours of total use.
• Best controls while moving → occiam Sport. Physical volume buttons with tactile feedback beat touch surfaces for gloves, sweat and mid-run adjustments.
• Best water and sweat protection → sprtoybat Earbuds. IPX7 versus IPX5 is a meaningful gap for rain, heavy sweat and outdoor work.
• Best connectivity and range → sprtoybat Earbuds. Bluetooth 5.4 with a 15-metre range versus Bluetooth 5 at 10 metres.
• Best for big-driver bass and call clarity in noise → sprtoybat Earbuds. 14.2 mm graphene drivers plus a 75% ENC noise-reduction claim.
• Best for lightweight all-day comfort → occiam Sport. Around 8 grams per bud with contoured silicone hooks.
• Best for minimal fuss → occiam Sport. Take them out, they pair; press a button, it works. No touch learning curve.
If I were buying one pair with my own money, I'd take the sprtoybat Earbuds. In my opinion the combination of Bluetooth 5.4, a 15-metre range, IPX7 protection and a 68-hour reserve is the more future-proof package, and it covers more of the situations I'd actually use buds in — running in the rain, long days away from a charger, calls from noisy places. The occiam Sport is the better pick only if physical buttons are non-negotiable for you, and for a lot of runners that's a genuinely strong reason. Check the current price on Amazon before you decide, since that's the one variable I can't weigh for you.

Not active noise cancelling. sprtoybat uses passive noise cancellation from the ear tip seal plus an ENC microphone that's quoted as reducing background noise by about 75% on calls. occiam uses environmental noise cancellation on the mic for the same purpose.
occiam Sport. Each bud has dedicated volume + and − buttons with tactile feedback plus a multifunction button. sprtoybat relies entirely on touch controls on the bud surface.
sprtoybat Earbuds, with Bluetooth 5.4 and a quoted 15-metre range. occiam Sport uses Bluetooth 5 with a 10-metre range, which is more prone to dropouts through walls.
