TOZO NC9 Earbuds

Are you tired of loud background noise, engine hums, or office chatter ruining your music and podcast listening? Do you struggle to find in-ear earbuds that actually stay comfortable and securely sealed during long commutes, workouts, or remote work shifts?

Today, I am taking a detailed look at the TOZO NC9, a pair of hybrid active noise-cancelling (ANC) true wireless earbuds designed to combine deep sound, impressive battery endurance, and daily practical durability.

Finding a reliable pair of budget-friendly ANC earbuds often means sacrificing call clarity, water protection, or app customisation.

The TOZO NC9 earbuds aim to address these concerns head-on, boasting a maximum noise reduction depth of up to 45dB, 6-microphone ENC call noise reduction, IPX8 waterproofing, and up to 60 hours of total playtime.

I have been testing the TOZO NC9 across everyday routines, and music listening to see how it performs in real-world conditions.

Let’s jump straight into the full review and see if the TOZO NC9 is the right ANC upgrade for your everyday setup!

Packaging and Contents.

The TOZO NC9 arrives in neat, compact retail packaging that keeps the earbuds and accessories well-protected.

Inside the box, you will find:

• 1x Pair TOZO NC9 Earbuds
• 1x Smart Digital Display Charging Case
• 6x Pairs Replaceable Ear Tips (Different Sizes)
• 1x USB Type-C Charging Cable
• 1x User Manual

The inclusion of six different ear tip sizes ensures you can easily dial in a snug, airtight seal, which is critical for both passive isolation and optimal ANC performance.

Design and Build Quality.

The TOZO NC9 features an ergonomic, stemless in-ear design styled to sit comfortably and securely inside the ear contour.

Because TOZO supplies six pairs of replaceable silicone ear tips, finding the ideal fit is straightforward, preventing ear canal pressure during extended listening sessions.

The charging case incorporates an integrated digital display that reveals the exact remaining battery percentage, taking out any guesswork when heading out the door.

For active users, the earbuds boast an impressive IPX8 water resistance rating, making them exceptionally well-protected against heavy sweat, rain showers, and accidental splashes during outdoor activities or gym workouts.

Controls, Noise Cancellation, and App Customisation.

The TOZO NC9 utilises Bluetooth 5.3 technology, offering a stable wireless connection up to 15 metres alongside low latency for synchronised video streaming and gaming.

The headline feature here is the Hybrid Active Noise Cancellation, which offers up to 45dB of noise reduction depth.

It effectively dampens ambient low-frequency rumbles like public transport noise, air conditioning units, and background hums.

When you need to stay aware of your surroundings, such as crossing busy roads or listening for transit announcements, switching to Transparent Mode lets environmental sound in clearly without removing the earbuds.

For voice calls, the NC9 features a 6-microphone array with Environmental Noise Cancellation (ENC) that actively filters out background clutter so your voice remains clear during phone calls and online meetings.

Touch controls on the earbud faces handle playback and mode switches smoothly, but connecting to the official TOZO App unveils far greater versatility.

Inside the app, you can choose from 32 EQ options, adjust bass levels, tweak ANC modes, and even share custom sound profiles with other users in the global ‘EQ Zone‘.

Sound Performance.

Audio delivery on the TOZO NC9 is driven by built-in 10mm dynamic drivers paired with TOZO’s proprietary OrigX Acoustic 2.0 sound technology.

The OrigX 2.0 tuning enhances low-end vibration, delivering a warm, punchy bass response while maintaining acoustic balance across vocal and instrumental tracks.

Acoustic Breakdown

• Bass: Deep, energetic, and rich. The 10mm drivers excel at producing satisfying low-end impact without overpowering the rest of the soundstage.
• Mids: Spoken dialogue, vocals, and podcast audio come through clearly and smoothly, keeping lyrics articulate.
• Highs: Treble frequencies are crisp and well-defined, providing lively detail for acoustic instruments and cymbals without causing listening fatigue.

The overall sound signature is energetic and engaging, offering a great balance for daily commuting, workouts, streaming movies, or casual music listening.

Technical Specifications.

Conclusion.

The TOZO NC9 is a well-rounded pair of wireless earbuds that punches above its weight in features and everyday battery endurance.

With up to 45dB hybrid active noise cancellation, 6-microphone ENC call noise reduction, an IPX8 waterproof rating, and six ear tip size options, it delivers reliable performance across travel, work, and exercise scenarios.

Combined with punchy 10mm OrigX 2.0 sound, up to 60 hours of total battery life, a smart digital display case, and extensive EQ customisation inside the TOZO App, the NC9 stands out as a highly practical, all-around performer.
