TOZO NC9 vs Soundcore P30i

Forty-five decibels against 42. On paper the TOZO NC9 (2024) wins the spec sheet almost everywhere that can be measured. Its hybrid ANC is rated up to 45 dB, the buds run 10 hours with ANC on against the Soundcore P30i’s 7, the case stretches total runtime to 42 hours against 30, and it carries an IPX8 rating and 6 mics where the P30i has IP54 and 4. The P30i answers with the two things TOZO left out. Bluetooth 5.4 multipoint holds a laptop and a phone at once, and its bigger, cleaner mid-bass rewards anyone who gets a proper seal. That’s the trade. Stronger cancelling and longer battery on one side, smarter connectivity on the other.

Which has stronger noise cancelling? The NC9, and not by a small margin. Its 45 dB hybrid ANC is consistently rated better than the P30i on constant low-frequency noise, the kind you get from jet engines, desk fans and wind on a motorcycle. You’ll hear a faint hiss with ANC on, and sharp high sounds still get through, but engine rumble drops further than the P30i manages. Battery is the other gap. Ten hours per charge with ANC on, 14 with it off, and 59 hours total from the case in ANC-off mode. Two hours refills that case over USB-C. The IPX8 rating covers full submersion, which no gym session or rainstorm will ever test. Six ear tip sizes and a round, low-profile shell earn the NC9 better comfort marks for long sessions. The case shows remaining charge as a percentage on an LED readout, the TOZO app has 32 presets plus a custom EQ, and a low-latency game mode keeps video and mobile games in sync. Eight colours, too. Sound is where the NC9 is weaker. It’s warm and thick with forward vocals, but there’s a harsh upper-mid peak some listeners dislike and the maximum volume runs lower than the P30i.

Multipoint is the P30i’s trump card. It pairs to two devices at once over Bluetooth 5.4 and switches automatically, so you can take a phone call mid-meeting without touching a menu. NC9 owners complain about reconnecting by hand every time they move between laptop and phone, and no amount of battery fixes that. The adaptive ANC, rated up to 42 dB, sits mid-pack among budget buds. It handles bus and train rumble well enough and does little against voices. Bass is the P30i’s stronger suit. The 10 mm driver pushes bigger, cleaner mid-bass than the NC9, though the lower mids get muddy and the treble rolls off; reviewers say the Treble Booster preset in the Soundcore app is close to mandatory, and HearID plus 22 presets give you room to tune it. Calls are solid in a quiet room and fragile in wind. The case folds out into a phone stand, Soundcore advertises 10 minutes of charging for 2 hours of playback, and IP54 covers sweat and dust. Amazon also flags a newer P31i on the P30i listing, which tells you this model is near the end of its run.

Picture a long-haul flight. You settle in, switch the NC9 to ANC and the engine drone falls away further than the P30i can take it. Ten hours later the buds are still going; the P30i would have gone back to the case once already and be close to needing it again. Now picture an office day. Your laptop is on a call, your phone rings, and the P30i just hands over. The NC9 makes you disconnect and re-pair, and by the third time you’ll resent it. At the gym both survive sweat, but IPX8 means the NC9 shrugs off a rinse under the tap, where IP54 means you should only wipe the P30i down. Side-sleepers do better with the NC9’s low-profile shell and its six tip sizes, since the P30i loses its seal easily and, with it, both its ANC and its bass.

Buy the TOZO NC9 (2024) if you fly, ride, mow or sit near anything that hums, and if you want the buds to outlast a workday with 10 hours of ANC-on playback. It’s also the pick for anyone who struggles with fit, thanks to six tip sizes, and for mobile gamers who need the low-latency mode. The Soundcore P30i is the right call for the laptop-plus-phone crowd, full stop. Multipoint over Bluetooth 5.4 saves more daily friction than 3 dB of ANC or 12 extra hours of case battery ever will, and its mid-bass hits harder once the seal holds. Neither pair is a call headset. The NC9’s six mics still sound thin and cut out in wind, and the P30i fades the moment a breeze picks up. If you mostly take calls, look at the Jabra tier above instead. For everyone else the split is simple. Noise and stamina, NC9. Two devices at once, P30i.
