TOZO NC9 Pro In-Ear Earbuds

Summary
The TOZO NC9 Pro impressed me with a comfortable fit, effective noise cancellation and useful touchscreen case controls. EarTune transformed the default sound into a more enjoyable listening experience. Calls stayed clear, and long desk sessions presented no battery concerns. Translation needs improvement, and this model still lacks wireless charging. It gets the “SOUND & VALUE CHOICE” Badge.

Introduction
TOZO started in 2015 as a Seattle-based consumer electronics brand. Its range now includes earbuds, headphones, speakers and smart wearables. Audio remains an important part of that line-up, with both sealed in-ear and open-ear designs.
I have already reviewed the TOZO NC9, Crystal Pods and NC20 Pro on CriticReviewer. Those experiences gave me a useful starting point for this review.
This time, I wanted to know whether a touchscreen case would remain useful once the initial excitement faded. More importantly, would I enjoy the sound?
My testing gave me a clear answer. I kept using the case controls, but EarTune made the biggest difference to my listening experience. Here is my experience with the TOZO NC9 Pro earbuds.
Design and build quality
I received the Black variant. Despite that colour name, both the case and earbuds have a matte black finish. The ABS plastic construction feels sturdy, and the details give the product a polished appearance.
A shiny band separates the case lid from its base. The TOZO logo sits on top, while the flat bottom lets the case stand upright on my desk. Rounded edges make it comfortable to carry in a trouser pocket.
The rear houses the reset button and USB Type-C charging port. The hinge feels secure, with no noticeable wobble when open. I could open the compact case with my thumb when holding it at the right angle.
The earbuds use a compact, bean-shaped design without long stems. A shiny TOZO logo contrasts with each matte shell. The inner surfaces carry L and R markings, while small LEDs and microphone openings complete the design.
TOZO lists each earbud at about 4.9g. My package included the fitted silicone tips and five additional sizes. Choosing the right tips matters because fit affects both comfort and noise isolation.
Comfort during work and walks
I used the NC9 Pro at my desk and during evening walks. The earbuds stayed comfortable and didn’t irritate my ear canals. Their compact shape also caused no problems when I wore glasses.

My desk sessions included watching YouTube while working, sometimes for more than four hours continuously. I did not experience the pressure or discomfort that can make in-ear earbuds distracting.
That does not guarantee the same fit for everyone. However, the range of silicone tips gives buyers useful options. Take time to choose the size that feels secure without forcing the earbuds deeper.
A touchscreen case I actually used
The 1.47-inch colour LCD touchscreen is more than a battery display. During testing, I used it to control music playback, volume, ANC and EQ without opening the TOZO app.

Music controls became my most-used feature. At my desk and outdoors, the case provided a convenient way to make adjustments without reaching for my smartphone.
TOZO also adds a deliberate unlocking process. With the case closed, two quick taps wake it. Opening the lid also activates the display. Either way, I still needed to swipe to access the controls.
That extra step helps prevent accidental operation. Slightly sweaty fingers sometimes activated the screen, although I preferred using it with dry hands.
The screen appeared solid during my review, but I cannot judge long-term scratch resistance from this short testing period. I also keep the case dry rather than treating it like a water-resistant accessory.
Audio quality improves with EarTune
TOZO specifies 10mm SDLC dynamic drivers, OrigX Pro tuning and LDAC support. It also advertises Hi-Res Audio Wireless. Those features provide context, but my listening experience matters more than the badges.

I tested Indian and Western classical music, rock, pop, trance and R&B. My sources included high-resolution FLAC files and Anghami streams at the 128kbps setting I used.
The standard sound setting did not immediately excite me. It was usable, but I wanted a more satisfying balance. The turning point came when I tried EarTune in the TOZO app.
EarTune took me through different tones to create a personalised sound profile. Afterwards, bass, mids and treble suited my preferences much better. The result made the earbuds considerably more enjoyable.
Pink Floyd’s The Dark Side of the Moon became a useful example. I enjoyed the cymbal detail and the low heartbeat in Speak to Me. Those quieter elements helped the recording feel engaging.

Bass had the impact I wanted without leaving me dissatisfied with the rest of the presentation. For this price category, the sound impressed me. EarTune deserves attention before judging the earbuds from their default setting.
I would not claim they match every flagship model. However, their personalised sound gave me much of the enjoyment I expect from more expensive earbuds.
LDAC requires a compatible source device. My notes don’t establish which codec stayed active throughout testing, so I wouldn’t credit LDAC alone for these results.
ANC and transparency in daily use
TOZO claims hybrid ANC of up to 45dB. My tests focused on ordinary listening conditions rather than measuring that figure.
During evening walks, ANC reduced traffic noise noticeably and made music more enjoyable. Near traffic areas, I switched to Transparency Mode to hear more of my surroundings while the music continued.

I also tested indoors beside a loud fan and with television audio nearby. ANC substantially reduced both in my listening experience. Transparency brought the television sound back into awareness.
I kept the earbuds around 60% volume for these indoor and outdoor checks. These were subjective comparisons, not laboratory measurements of noise reduction.
The useful part was the easy switch between isolation and awareness. However, Transparency Mode does not replace removing earbuds and paying full attention when crossing a road.
Calls and Bluetooth connectivity

TOZO lists Bluetooth 6.0 and six-microphone environmental noise cancellation. ANC reduces the noise I hear; call noise processing aims to reduce background sound reaching the other person.
I tested BOTIM and Google Meet calls with my brother. I heard him clearly, and he said my voice sounded clear, without obvious muffling or excessive sharpness.
A loud fan beside me left a slight hiss at his end. Even so, it did not create a major disturbance. That is a useful result for everyday calls and online meetings.
Both earbuds also worked individually. I tested the left and right separately, which is useful when I want to keep one ear free.

Connection stability impressed me at home. Between my workroom and living room, the route runs through a long corridor and past walls. At roughly 12 to 14 metres, I noticed no dropouts or disturbance.
That is my result for one home layout, not a guaranteed range. TOZO also advertises multipoint and a low-latency mode. My recorded tests do not establish their full switching behaviour or gaming performance.
Battery life and USB-C charging
TOZO claims up to 14 hours per charge with ANC off, or 10 hours with ANC on. Including case recharges, the figures reach 60 and 40 hours respectively.
My real use covered continuous sessions of around four to five hours without battery concerns. I did not run the earbuds from full charge to empty, so I cannot confirm those maximum claims.

After a four-hour session, a short break in the case let me resume listening within ten minutes. This was a convenient top-up, not a timed test from an empty battery.
I charged the case using the supplied USB Type-C cable and a 45W GaN charger. That identifies my charger, rather than the power drawn by the case.
My review unit does not support wireless charging. I would welcome it, but USB-C was straightforward enough for my routine.
The TOZO app and its AI tools

The TOZO app has developed noticeably since my earlier reviews. Alongside EarTune and custom EQ, I found Find My Earbud and options to change the charging case wallpaper.
For me, EarTune was the highlight. I could also select an EQ preset or adjust individual frequencies. This flexibility mattered more to my listening than cosmetic customisation.
The meeting-recording feature converted conversation into on-screen text. I could copy and share that text for later use. It adds practical value when I want a written record of a discussion.
AI Chat answered my questions well during testing. However, Simultaneous Interpretation and Face-to-Face Translation still needed improvement. I encountered translation issues and checked key meanings before relying on the output.
The app also offers white-noise options, including rain and thunderstorm sounds. I could use these and the AI functions without the earbuds connected. They therefore add app value rather than being exclusive hardware benefits.
Water resistance and everyday care
TOZO’s published information is inconsistent: the current store page mentions IPX6, while its September 2026 launch announcement lists IPX8. Buyers should follow the rating and care instructions supplied with their exact unit.

I did not conduct immersion testing. My review therefore does not promise swimming suitability or protection from sand. I would avoid washing the earbuds and keep the charging case away from water.
What makes the NC9 Pro stand out
The useful combination is comfortable earbuds, personalised sound and controls directly on the case. I could leave my phone alone while adjusting the features I used most.
A touchscreen case isn’t unique, even within TOZO’s own range. My earlier NC20 Pro review covers another example. Nevertheless, the NC9 Pro makes the idea worthwhile through its everyday usability.

TOZO lists higher ANC and battery figures for the NC20 Pro. That does not automatically decide which sounds better to me. In my own use, I preferred the NC9 Pro listening experience, particularly after EarTune.
Against simpler earbuds, the case controls offer an obvious convenience. Against more expensive models, the appeal is how much listening enjoyment and practical functionality this package provides.
Price and availability
The NC9 Pro sits in TOZO’s affordable audio range. Prices and promotions vary between listings, and it is priced at AED 263.

Verdict
The TOZO NC9 Pro earned its place in my daily routine. Comfort, call quality, and connection stability impressed me, while the touchscreen gave me controls I kept using.
EarTune made the strongest impression. The default setting didn’t show me the earbuds at their best, but personalisation delivered sound I thoroughly enjoyed.
I recommend them to listeners who want comfortable ANC earbuds with useful case controls and flexible tuning. Translation needs work, and buyers looking for budget-friendly, excellent earbuds should consider the TOZO NC9 Pro.
My overall rating is 4.5 out of 5.
