Tozo NC9 (2024) specifications and in-depth review

Tozo NC9 (2024)

Manufacturer: Tozo

The Tozo NC9 (2024) is a true wireless in-ear earbud set built around a clean, cable-free design with a full suite of practical features. It carries an IPX8 waterproof rating with a depth tolerance of 1.5 meters, making it suitable for use in demanding conditions. A travel bag is included in the box, and voice prompts along with a battery level indicator help keep the user informed during everyday use.

On the technical side, the NC9 uses a 9 mm driver unit covering a frequency range of 15 Hz to 20,000 Hz, and incorporates active noise cancellation alongside passive noise isolation and an ambient sound mode for situational awareness. Six microphones with noise-canceling capability support its headset functionality. Connectivity runs on Bluetooth 5.3 with AAC codec support and a maximum range of 10 meters, while a USB Type-C port handles charging. The earbuds deliver 14 hours of playback on a single charge, with the case extending total battery life to 45 hours, and fast charging is supported with a full charge time of 2 hours.

Pros
  • IPX8 waterproof rating with a 1.5-meter depth tolerance makes it suitable for use in wet or rainy conditions
  • Active noise cancellation combined with passive noise isolation offers two layers of sound blocking
  • Six-microphone array with noise-canceling support is well-suited for calls and voice use
  • The charging case extends total battery life to 45 hours, reducing the need for frequent recharging
  • Fast charging support helps minimize downtime when the battery runs low
  • Ambient sound mode allows the user to stay aware of surroundings without removing the earbuds
Cons
  • No wireless charging support, requiring a physical USB-C connection every time
  • Audio latency of 158 ms may be noticeable when watching video or playing games
  • No in-ear detection means playback does not pause automatically when the earbuds are removed
  • No find device feature, which can be inconvenient if an earbud is misplaced
  • Lacks advanced audio codecs such as LDAC or aptX, limiting high-resolution wireless audio options
  • No NFC or fast pairing support, making the initial connection process less convenient
Who is this for?

The Tozo NC9 (2024) is well-suited to users who need reliable earbuds for active or outdoor use, thanks to its IPX8 waterproof rating with a 1.5-meter depth tolerance. The combination of active noise cancellation and passive noise isolation makes it a practical choice for commuters or those working in noisy environments who want to block out distractions. With a six-microphone noise-canceling setup and headset capability, it also works well for users who frequently take calls or participate in remote meetings, while the 45-hour total battery life suits those who need extended use across multiple days without regular recharging.

Who is this NOT for?

Users who prioritize high-resolution wireless audio will find the Tozo NC9 (2024) limiting, as it lacks support for advanced codecs such as LDAC or any aptX variant, leaving AAC as the only enhanced option. The 158 ms audio latency makes it a poor fit for those who watch video content or play games where audio and visual sync is important. Additionally, the absence of spatial audio and in-ear detection means users who value an immersive listening experience or hands-free convenience when removing the earbuds will likely find the feature set insufficient for their needs.
