TOZO NC9 Wireless Earbuds Review: Hybrid ANC, 60-Hour Battery, Clear Calls, and Custom EQ

Introduction

Wireless earbuds have become a practical choice for music, calls, commuting, travel, and remote work. The TOZO NC9 Hybrid Active Noise Cancelling Wireless Earbuds combine several features aimed at everyday listening, including hybrid active noise cancellation, six microphones, transparency mode, customizable EQ settings, extended battery life, and an IPX8 rating.

The earbuds use Bluetooth 5.3 connectivity and feature 10mm drivers with TOZO’s OrigX Acoustic 2.0 sound technology. A charging case with an LED display provides additional battery capacity, while six different sizes of replacement ear tips allow users to adjust the fit.

With a combination of noise control, call features, customizable sound, and long battery life, the NC9 is designed for a variety of everyday situations.

Hybrid Active Noise Cancellation

One of the main features of the TOZO NC9 is its Hybrid Active Noise Cancelling technology.

The manufacturer states that the earbuds provide a maximum noise reduction depth of 45dB.

Active noise cancellation is designed to reduce surrounding sounds so users can focus more easily on their audio.

This can be particularly useful in environments such as:

• Public transportation
• Offices
• Coffee shops
• Airports
• Busy streets
• Home working environments

The level of noise reduction can vary depending on the surrounding environment and the type of sound being produced.

Six-Microphone Call System

The NC9 includes a six-microphone system with ENC ambient noise reduction.

The microphone arrangement is designed to help filter surrounding sounds during phone calls and other voice communication.

This can be useful when making calls in environments where background noise is present.

The combination of multiple microphones and ENC processing is intended to make conversations easier to hear while allowing users to communicate without removing the earbuds.

Transparent Mode

Noise cancellation isn’t always desirable.

When users need to hear what’s happening around them, the NC9 provides a Transparent Mode.

This mode allows surrounding sounds to pass through so users can remain aware of their environment without removing the earbuds.

It can be useful when:

• Walking outdoors
• Waiting for announcements
• Commuting
• Talking with someone nearby
• Working in shared spaces

Being able to switch between noise cancellation and transparency provides flexibility depending on the situation.

60 Hours of Total Playtime

Battery life is another major feature of the NC9.

According to the product information, the charging case provides up to 60 hours of total playtime with ANC turned off and up to 40 hours with ANC turned on.

The earbuds themselves provide up to:

• 14 hours on a single charge with ANC off
• 10 hours on a single charge with ANC on

The manufacturer states that the case takes approximately 2 hours to fully charge.

Actual battery performance can vary depending on factors such as volume, connectivity, ANC usage, and other operating conditions.

LED Battery Display

The charging case includes an LED display that shows the remaining battery level.

This provides a convenient way to check the available power before using the earbuds.

Rather than relying entirely on a connected phone to determine the case’s battery status, users can check the charging case directly.

This can be particularly helpful before leaving home for work, travel, or a workout.

10mm Drivers and Bass-Focused Sound

The NC9 uses 10mm drivers combined with TOZO’s OrigX Acoustic 2.0 sound technology.

The manufacturer describes the audio profile as providing deep bass alongside precise audio clarity.

The sound design is intended for a variety of content, including:

• Music
• Movies
• Podcasts
• Videos
• Phone calls

The 10mm drivers provide the physical hardware for the earbuds’ stereo sound reproduction, while the sound technology is designed to shape the overall listening experience.

32 EQ Settings

One feature that gives the NC9 additional flexibility is its 32 EQ settings.

Equalization allows listeners to adjust the balance of different sound frequencies according to their preferences.

This can be useful for people who prefer different sound profiles depending on what they’re listening to.

For example, some users may prefer stronger bass for certain types of music, while others may prefer a more balanced presentation for podcasts or spoken content.

Having multiple EQ options gives users more control over how the earbuds sound.

Comfortable In-Ear Fit

The NC9 uses an ergonomic in-ear design intended to sit securely inside the ear.

The product includes six sizes of replacement ear tips, allowing users to choose the size that provides the most suitable fit.

Having multiple sizes can be particularly useful because ear shapes vary from person to person.

A properly fitted ear tip can also help the earbuds remain securely positioned during everyday movement.

The fit can be adjusted according to individual comfort preferences, making the earbuds suitable for longer listening sessions.

IPX8 Water Resistance

The earbuds feature an IPX8 water-resistance rating according to the supplied product information.

This provides protection against water exposure and makes the earbuds suitable for situations where they may encounter moisture.

The feature can be useful during workouts, outdoor activities, and everyday travel.

As with any water-resistant electronic product, users should follow the manufacturer’s instructions regarding appropriate water exposure and maintenance.

Bluetooth 5.3 Connectivity

The NC9 uses Bluetooth 5.3 for wireless communication with compatible devices.

Bluetooth connectivity allows the earbuds to be used with smartphones, tablets, computers, and other compatible electronics.

This makes them suitable for both entertainment and communication.

Users can listen to music or videos, make calls, and switch between different types of audio content without needing a physical cable.

Designed for Remote Work

The combination of ANC, multiple microphones, and long battery life makes the NC9 suitable for remote work environments.

Noise cancellation can help reduce surrounding distractions while working, while the microphone system supports voice communication.

The earbuds can be used for:

• Video meetings
• Voice calls
• Online collaboration
• Listening to presentations
• Working in shared spaces

The transparency mode can also be useful when users need to hear people or sounds around them without removing the earbuds.

Useful for Travel and Commuting

The NC9’s long battery life and noise-control features make it suitable for travel and commuting.

The charging case provides multiple additional charges, while the ANC mode can be used to reduce surrounding noise.

The transparent mode provides another option when environmental awareness is needed.

The compact charging case also allows the earbuds to be stored and transported when they aren’t being used.

For frequent travelers, having extended battery capacity can reduce the need to recharge the earbuds during shorter trips.

Everyday Controls and Convenience

Wireless earbuds become more useful when common functions can be managed without constantly reaching for a phone.

The NC9’s overall feature set is designed around this type of convenience.

Users can move between listening, calls, noise cancellation, and transparency depending on their situation.

Combined with Bluetooth 5.3 and the charging case, this creates a setup intended for regular everyday use rather than a single specialized activity.

Who Are the TOZO NC9 Earbuds Best For?

The NC9 can be a practical option for users looking for wireless earbuds with a broad collection of features.

They may be suitable for:

• Music listeners
• Remote workers
• Commuters
• Travelers
• Office workers
• People who make frequent calls
• Workout users
• Listeners who prefer customizable EQ
• Users who want multiple ear-tip sizes

The combination of ANC, transparency mode, six microphones, long battery life, and adjustable sound gives users several ways to customize their listening experience.

The 45dB maximum noise reduction, six-microphone ENC system, and Transparent Mode provide different ways to manage surrounding sound, while the 10mm drivers and OrigX Acoustic 2.0 technology are designed to deliver deep bass and clear audio.
