How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want maximum battery life with a security-first sport fit, choose sprtoybat Ear Buds; if you need real hybrid active noise cancelling and app-level sound tuning, choose TOZO NC9. This is a genuinely close call, but the two earbuds are built around different priorities, and once you see what each one optimizes for, the decision gets simple.
• sprtoybat Ear Buds — biggest strength: enormous 68-hour total playtime with fast charging that delivers 2 hours of music from a 10-minute top-up, plus IPX7 sweat and water resistance and flexible TPU ear hooks.
• sprtoybat Ear Buds — biggest trade-off: no transparency mode and no companion app, so you get one fixed sound signature and no adjustable bass or EQ profiles.
• TOZO NC9 — biggest strength: hybrid active noise cancelling rated to a 45dB reduction depth, six microphones for calls, a transparency mode, and 32 EQ options through the TOZO app.
• TOZO NC9 — biggest trade-off: shorter total playtime than the sprtoybat buds, and the in-ear design relies on ear tips rather than hooks to stay put during hard movement.
• Who each pick is for: sprtoybat if you run, cycle or work out and hate charging; TOZO NC9 if you commute, travel or take a lot of calls in loud places.
The sprtoybat Ear Buds are unapologetically a sport-first pair. The design tells you that immediately: flexible TPU ear hooks, three sizes of soft sport tips (S/M/L), and an IPX7 waterproof rating. IPX7 means sweat, rain and splashes are not a concern, and the hook shape is what keeps the bud anchored when you are moving rather than sitting still. If your earbuds usually work themselves loose halfway through a run, this is the style of fit built to prevent that.
Battery is the headline number here, and it is a big one. You get up to 8 hours on a single charge, and the 800mAh charging case recharges the buds roughly 8 to 9 times for up to 68 hours of total listening. The fast-charge spec is the part I find most practical: 10 minutes in the case gives you about 2 hours of music. That is the difference between a rushed pre-gym top-up actually working and not. On the audio side, sprtoybat uses 14.2mm dual-layer graphene drivers, an 80-ohm impedance rating, and a 20Hz–20,000Hz frequency range, with an ENC microphone that the spec sheet says cuts background noise by 75% for calls.
Connectivity is current-generation Bluetooth 5.4 with a 15-meter range, and it pairs automatically to the last device once you turn it on. Touch controls handle play/pause, volume, calls and your voice assistant. The trade-offs are worth naming honestly. There is no transparency mode, so you cannot let the outside world in without pulling a bud out. There is no app, which means no EQ adjustments — you get the tuning sprtoybat shipped it with. And the case itself is compact to the point of being tiny, which is great in a pocket but easy to misplace.
Who should buy it: runners, cyclists, gym-goers and anyone who wants to charge as rarely as possible. Who should skip it: commuters who want to silence a train carriage, and tinkerers who want to shape their own sound.
The TOZO NC9 attacks the opposite problem: the noisy world around you. Its hybrid active noise cancelling is rated to a maximum reduction depth of 45dB, which is the kind of figure that matters on a plane, a subway or a loud open office. Just as importantly, it adds a transparency mode, so you can hear announcements, traffic or a barista without removing the buds. That one feature changes how usable a pair is outdoors, and it is the single biggest functional gap between these two products.
Call quality is the second pillar. TOZO fits six microphones with ENC ambient noise reduction, which is a serious amount of hardware aimed at keeping your voice clear in busy environments. For anyone who spends their day on calls, that is a real-world advantage over a single-mic setup. Sound comes from 10mm dynamic drivers with TOZO's OrigX Acoustic 2.0 tuning, an impedance of 32 ohms, sensitivity rated at 120dB, and a 60ms audio latency figure that matters if you game or watch video and hate lip-sync drift.
The app is where the NC9 pulls away for enthusiasts. You get 32 EQ options, adjustable bass, noise-cancelling modes, firmware updates, and a sharing zone where you can post your custom EQ for other listeners. Fit is handled by ergonomic in-ear shaping with six sizes of replaceable ear caps, which is a wider size spread than most. Water protection is IPX8 — a step above IPX7 — and connectivity is Bluetooth 5.3 with a 20-meter range. Battery runs up to 60 hours total with ANC off and 40 hours with ANC on, or 14 and 10 hours respectively per single charge, with a full charge taking about 1.5 hours. The LED display on the case shows remaining battery.
The honest trade-off: with ANC on, total playtime drops to 40 hours, which is meaningfully less than sprtoybat's 68. And because these are in-ear buds with tips rather than hooks, fit security during vigorous movement depends entirely on getting the right ear cap size.
Who should buy it: commuters, frequent flyers, remote workers on calls, and anyone who wants to tune their own sound. Who should skip it: people who want the longest possible time between charges and prefer a hooked, locked-in fit.
• Best for battery life → sprtoybat Ear Buds, with up to 68 hours total versus TOZO's 60 hours with ANC off.
• Best for noise cancelling → TOZO NC9. Hybrid ANC rated to 45dB is a genuine feature sprtoybat does not offer.
• Best for calls in loud places → TOZO NC9, with six microphones and ENC versus sprtoybat's single ENC mic.
• Best for running, cycling and sweating → sprtoybat Ear Buds, thanks to IPX7 plus TPU ear hooks that resist movement.
• Best for customizing sound → TOZO NC9, with 32 EQ options and app control. sprtoybat has no app at all.
• Best for staying aware outdoors → TOZO NC9, which has a transparency mode. sprtoybat does not.
• Best for a fast emergency top-up → sprtoybat Ear Buds, at 2 hours of music from a 10-minute charge.
• Best for newer Bluetooth and longer range → a split decision — sprtoybat has Bluetooth 5.4, but TOZO reaches 20 meters versus sprtoybat's 15.
If I had to pick one for myself, I would buy the TOZO NC9. In my opinion, hybrid ANC at a 45dB reduction depth, a transparency mode, six call mics and app-based EQ cover more of the situations I actually run into — commuting, working and taking calls in noisy rooms. The sprtoybat Ear Buds are the better choice only if your life is genuinely built around training and you want to charge as little as possible; that 68-hour total and the ear-hook fit are excellent for exactly that. Neither is the wrong answer — they are just aimed at different people.
TOZO NC9 does. It uses hybrid active noise cancelling rated to a 45dB reduction depth and includes a transparency mode, while the sprtoybat spec sheet lists ENC for calls rather than a transparency setting.
sprtoybat claims up to 68 hours total with 8 hours per charge. TOZO NC9 claims up to 60 hours with ANC off and 40 hours with ANC on, at 14 and 10 hours per single charge respectively.
Yes — that is their design focus. They carry an IPX7 waterproof rating, come with flexible TPU ear hooks and three tip sizes, and are built for running, cycling and fitness use.
That depends on what you need most, so check the current price on Amazon before deciding. In my opinion, TOZO NC9 gives you more features per dollar if you want ANC and app tuning, while sprtoybat earns its keep if battery life and a secure sport fit are your priorities.
