Tozo NC9 Earbuds Review: The Hidden Gem Combining Comfort and ANC

Finding earbuds that offer both strong noise cancellation and long-lasting comfort can feel like an endless hunt. Some deliver powerful noise reduction but create uncomfortable pressure in the ears, while others are comfortable yet fall short on noise isolation. Tozo seems to have cracked the code with their NC9 model—a pair of earbuds that manage to walk that fine line between comfort and performance.

Straight out of the box, the Tozo NC9 makes a good first impression. The packaging includes the essentials—manuals, a warranty card, extra ear tips, and a Type-C charging cable. The charging case is compact, sleek, and simple, fitting easily into any pocket. What’s more impressive is the minimal design: no flashy embellishments, just a functional case with a battery indicator screen and the Tozo logo on top.

The earbuds themselves ditch the traditional stem design for a rounded, discreet shape that fits snugly in the ears. Thanks to the five different ear tip sizes included, achieving a secure and comfortable fit is effortless for most users. Even during high-motion activities like running or workouts, they stay firmly in place without discomfort. That secure fit, paired with IPX8 waterproof protection, makes them a strong choice for fitness lovers and outdoor users.

What makes the NC9 especially stand out is the smart integration with the Tozo app. Once connected, the app unlocks firmware updates, battery tracking, ambient noise control, and most notably, a customizable equalizer. You can choose from over 30 EQ presets or manually tailor the sound profile to your liking. That flexibility makes these earbuds highly adaptable, whether you’re listening to pop, podcasts, or even gaming audio.

The active noise cancellation (ANC) is surprisingly effective. Even before turning ANC on, the earbuds passively block a decent amount of ambient noise. Once activated, the effect is immediately noticeable—background distractions are significantly reduced without creating uncomfortable ear pressure. According to testing, external noise levels are cut down by nearly 45%, which aligns well with the brand’s claims.

On the audio front, the NC9 delivers crisp, detailed sound. While not studio-grade for professional mixing or classical music, it excels in mid and high frequencies. Vocals and instruments come through cleanly, making it a great choice for genres like pop, rock, and voice-centric content. Though the treble may lack a bit of sparkle for audiophiles, the overall sound profile is enjoyable and immersive for everyday listening.

Microphone quality also impresses. Voice calls remain clear, even in noisy settings like traffic-heavy streets. Background noise is efficiently filtered out, making conversations easy and pleasant on both ends.

Battery life is another strong suit. With a claimed total of 59 hours—including recharges from the case—the NC9 easily surpasses many competitors. In real-world use, this claim holds up. Charging is quick via USB-C, though wireless charging is notably absent.

In terms of connectivity, the Bluetooth 5.3 ensures fast and stable pairing across devices including Android, iOS, Windows, and macOS platforms. There are no noticeable lags or drops during calls or audio streaming.

All in all, the Tozo NC9 is a compelling package. It’s well-suited for commuters, office workers, and anyone looking for noise cancellation without sacrificing comfort or affordability. Audiophiles may crave more fine-tuning, but for most users, this is an excellent everyday earbud option.

Tozo lives up to its motto—“Just for Good Sound.”
