TOZO wireless earbuds NC9

The TOZO NC9 combines hybrid active noise cancellation with a transparency mode, so you can switch between focusing on audio and hearing more of your surroundings without removing the earbuds. The listing gives a maximum noise-reduction depth of 45 dB, plus six microphones with ENC for calls, those figures describe the intended features, not a guarantee of how they’ll perform in every setting. With Bluetooth 5.3, app-based sound adjustments and a charging case with a battery display, it’s designed for everyday listening with a few ways to tailor the experience. One detail to keep in mind is that the longest stated total playtime applies with ANC turned off.

Technical details

The NC9 uses 10 mm drivers and TOZO’s OrigX Acoustic 2.0 technology, with a bass-forward sound profile described by the manufacturer. The TOZO app offers 32 EQ options, giving you room to adjust the sound rather than relying on a single preset. The six sizes of replaceable ear tips also give you more fit options than earbuds supplied with only a small and large pair.

The case’s stated total playtime is up to 60 hours with ANC off, or up to 40 hours with ANC on. For one listening session, the listed figures are 14 hours with ANC off and 10 hours with it on. The case has an LED battery display, and a full charge is listed as taking two hours. IPX8 water resistance is another stated feature, though the product information doesn’t explain specific use conditions.

Getting the most from it

These earbuds make sense if you want noise cancellation for music or podcasts, but also value a transparency mode for moments when you need to hear more around you. For example, you could use ANC while listening during a commute, then switch modes before stepping into a busier outdoor setting. That flexibility may suit you better than a basic pair with no listening modes, while someone mainly after simple, low-feature earbuds may not need the app controls or six microphones.

The six-microphone ENC setup is intended to reduce background noise on calls. It’s a useful feature to look for if you take calls in shared or noisy spaces, although the listing doesn’t provide call-quality results from particular environments. Based on the listed details, the strongest case for the NC9 is its mix of mode options, EQ customisation and stated battery life—not a promise that it will block every sound or make every call clear.

Usage tips

Try different ear-tip sizes before settling on one. A secure, comfortable fit matters for all-day wear, and the supplied range gives you alternatives if the first pair feels loose or uncomfortable. Once the fit feels right, use the app’s EQ options to adjust bass or choose a sound style that suits what you’re listening to.

Use transparency mode when hearing your surroundings matters, and ANC when you want to focus more on audio. If you rely on long stretches between charges, compare the single-use figures with your routine: the listed playback drops from 14 hours to 10 hours when ANC is on. The case display can help you keep an eye on its remaining battery.

Before you decide

The NC9 may suit you if you want ANC, a transparency mode and app-based EQ adjustments in one pair of earbuds. It may not be the best choice if your priority is the longest possible listening time with ANC enabled: the stated 40-hour total includes the case, while a single use is listed at 10 hours with ANC on. Also, IPX8 is stated, but the product details don’t spell out the conditions behind that rating, so don’t assume it makes the earbuds suitable for every water-related activity.

Before you decide

How long do the earbuds last on one use? The listed playback time is up to 14 hours with ANC off and up to 10 hours with ANC on.

Can I change the sound? Yes. The TOZO app provides 32 EQ options for adjusting the sound profile.

Can I hear my surroundings without taking them out? Yes. The product includes a transparency mode for hearing more of your surroundings while the earbuds remain in place.

Before you buy

Choose the TOZO NC9 if you’ll use its listening modes, app EQ and included range of ear tips, and the stated playtime fits your routine. If ANC will stay on for most of your listening, judge it by the listed 10-hour single-use figure rather than the case’s 40-hour total. That distinction is more useful than the headline battery number when deciding whether it suits your day.
