Overview

The TOZO NC9 arrived in mid-2024 as a genuinely compelling entry in the crowded budget wireless earbud space, targeting daily commuters and gym regulars who want real noise cancellation without the premium price tag. TOZO built these around 10mm dynamic drivers paired with their OrigX Acoustic 2.0 tuning — a more thoughtful foundation than you typically encounter at this tier. The charging case is notably compact, sports an LED battery display, and the earbuds carry an IPX8 waterproof rating that is genuinely rare among direct competitors. Bluetooth 5.3 handles the wireless connection, keeping pairing stable across most everyday devices and scenarios without fuss.

Features & Benefits

The headline capability is hybrid active noise cancellation, combining feedforward and feedback microphones to cut ambient sound. At this price, you should not expect the hush of premium flagship earbuds, but the reduction is solid enough to meaningfully dull office chatter, transit rumble, and street noise. A transparency mode lets you stay aware of your surroundings without removing the buds. The six-microphone array handles call clarity with environmental noise filtering, and most users notice cleaner voice pickup versus cheaper alternatives. Battery stamina is a real strength — a single charge comfortably covers a full workday, with the case extending total runtime considerably. The TOZO app unlocks 32 EQ presets and touch control customization, plus a community EQ sharing feature.

Best For

These wireless earbuds are a natural fit for commuters who ride trains or buses daily and want to dull ambient noise without spending heavily. The waterproofing also makes them a smart choice for runners and gym-goers — they handle heavy sweat sessions or light rain without concern. Remote workers and students who field frequent calls in coffee shops or shared spaces will appreciate the multi-mic setup. If you enjoy tinkering with sound profiles, the NC9 buds offer more EQ flexibility than most rivals in this range. Travelers will find the extended battery life and slim case particularly convenient for long-haul journeys where charging opportunities are limited.

User Feedback

Across tens of thousands of ratings, the pattern is fairly consistent: buyers are pleasantly surprised by how effectively this ANC headset blocks ambient noise at its price, and call quality earns frequent praise in noisy environments. The 4.3-star average feels earned rather than inflated by volume alone. That said, fit is a recurring concern — users with smaller or larger ear canals sometimes struggle to achieve a proper seal, which directly affects both bass depth and ANC effectiveness. Some reviewers also find the app occasionally clunky, with EQ settings sometimes resetting after reconnects. Build quality draws mixed reactions; most consider it acceptable, though the plastic finish does not inspire strong long-term confidence.

Value for Money

93%

At this price point, getting hybrid ANC, IPX8 waterproofing, and a multi-day battery case in one package is objectively hard to beat. Most buyers feel they received substantially more than they paid for, and that sentiment comes through consistently across reviewer demographics ranging from students to frequent travelers.

A small but vocal segment of buyers feel the value equation shifts if you factor in long-term durability. If the earbuds need replacing within a year, the per-use cost starts to look less impressive, and a few reviewers noted they had to repurchase after issues arose.

Active Noise Cancellation

74%

26%

For everyday commuters dealing with bus engines, train rumble, or open-plan office chatter, the ANC does a commendable job of dulling the ambient environment. Most users report a noticeable and satisfying reduction in background noise during their daily routines, which is the core use case these buds are built for.

Anyone expecting the near-silence of premium earbuds will be disappointed — the ANC ceiling is real, and higher-frequency sounds like voices or sharp ambient noise cut through more than users hope. Reviewers who upgraded from flagship earbuds are particularly candid about this gap.

Battery Life

91%

The single-charge stamina comfortably covers a full workday with ANC active, and the case extends that runway considerably for multi-day trips without wall access. Travelers and long-haul commuters consistently highlight this as one of the strongest reasons they chose these buds over rivals in the same tier.

Battery performance with ANC constantly enabled does drop meaningfully compared to ANC-off use, and some buyers noticed capacity degradation appearing sooner than expected after several months of heavy daily charging cycles.

Call Quality

78%

22%

The six-microphone setup earns genuine praise from remote workers and students who regularly take calls in cafes, transit hubs, or shared workspaces. Callers on the other end frequently report hearing voices clearly even in moderately noisy environments, which is a real-world differentiator at this price.

In very loud outdoor settings — busy streets, crowded venues — the environmental noise filtering hits its limits and voices can become muddier. A handful of reviewers also noted inconsistent mic pickup between the left and right earbuds depending on how each bud was seated.

Comfort & Fit

69%

31%

The ergonomic in-ear shape and six included eartip sizes mean most users can dial in a secure, comfortable fit relatively quickly. Gym users and runners particularly appreciate how securely the buds stay seated during movement, even during high-intensity sessions.

Fit consistency is the most common pain point across the review pool. Users with smaller or unusually shaped ear canals report difficulty achieving a proper seal, and without that seal both bass response and ANC effectiveness suffer noticeably. Extended wear over several hours can also cause mild fatigue for some.

Sound Quality

76%

24%

The 10mm drivers deliver a warm, bass-forward signature that suits pop, hip-hop, and workout playlists well. Most buyers are pleasantly surprised by the depth and body of the low end, which sounds fuller than the hardware cost typically promises in this category.

Audiophiles will notice that treble detail and soundstage width are sacrificed in favor of that bass emphasis. Acoustic, classical, or detail-oriented listening reveals a ceiling in clarity and instrument separation that more neutral-tuned earbuds handle better.

App Experience

62%

38%

The TOZO companion app gives access to 32 EQ presets and a community sharing zone for custom sound profiles, which is a genuinely fun feature for buyers who like tinkering. The interface is accessible enough for non-technical users to navigate basic adjustments without a steep learning curve.

EQ settings resetting after reconnects is a recurring frustration across multiple reviews, and some users report the app losing connection or failing to sync reliably on certain Android builds. The community EQ zone, while novel, is inconsistently populated and adds limited practical value day-to-day.

Build Quality

63%

37%

The earbuds feel adequately solid during handling, and the ABS plastic construction does not feel cheap in the way some ultra-budget earbuds do. The charging case snaps shut cleanly and the hinge mechanism feels well-constructed relative to similarly priced alternatives.

The overall plastic finish does not inspire strong confidence over the long term, and several reviewers noted cosmetic wear appearing relatively quickly with regular daily use. A few buyers across the large review pool also reported functional issues — loose eartip sockets, charging contact problems — within the first few months.

Waterproofing

88%

The IPX8 rating is one of the standout specs for this tier, and real-world feedback backs it up. Swimmers using them in shallow water, runners caught in rain, and gym-goers soaking through workouts all report no water-related failures, which builds genuine trust in the rating.

A small number of buyers reported moisture-related issues over extended periods, raising questions about whether the waterproof seal degrades with repeated exposure cycles. The case itself is not water-resistant, so dunking the case or leaving it in wet gym bags is still a risk.

Transparency Mode

71%

29%

Transparency mode is genuinely useful for outdoor runs and cycling, allowing ambient sound through clearly enough to hear approaching traffic or someone calling your name without pulling the buds out. Switching between modes via touch controls is fast and responsive in everyday use.

The transparency mode has an audible processing artifact — a subtle hiss or hollow quality — that sensitive listeners notice in quieter environments. It also does not sound as natural as the transparency modes found on higher-end competitors, which process ambient audio more faithfully.

Connectivity & Stability

81%

19%

Bluetooth 5.3 keeps the connection solid across most real-world scenarios — moving between rooms, commuting through crowded transit hubs, or switching between a phone and laptop. Pairing is quick and initial setup is straightforward across both iOS and Android.

A portion of reviewers — particularly on certain Android devices — report occasional dropouts or audio stutters in environments with heavy wireless interference. Multipoint connectivity, the ability to stay paired to two devices simultaneously, is absent, which frustrates users who regularly switch between a phone and computer.

Touch Controls

72%

28%

The touch controls cover the essential functions — play, pause, skip, volume, ANC toggle — and respond accurately enough for daily use. Most buyers adapt to the control layout within a day or two of regular use without needing to consult the manual.

Accidental touches when adjusting earbud fit are a frequent minor annoyance, particularly during workouts when hands are sweaty and contact with the earbud surface is unavoidable. The touch sensitivity cannot be adjusted in the app, which limits the ability to reduce false triggers.

Latency

67%

33%

For music and podcast listening, the audio latency is low enough that the experience feels natural and uninterrupted. Casual video watching on social platforms is generally fine, and most users do not notice any perceivable delay during typical media consumption.

For gaming or precise video editing work, the latency becomes more noticeable and distracting. There is no dedicated low-latency gaming mode, which puts these buds at a disadvantage against rivals that specifically address this use case at a similar price.

Charging & Case Design

84%

The LED battery display on the case is a genuinely practical touch that eliminates guesswork before heading out — you know exactly how much charge is left without opening the lid or checking an app. The USB-C charging cable is included, and a full case charge completes in a reasonable timeframe.

The case is on the thicker side for pocket carry compared to some slimmer rivals, and the LED display, while useful, occasionally dims or reads inaccurately for some users near the lower end of the battery range. The charging cable included is short and primarily suited for desk use.

Eartip Options & Accessories

79%

21%

Six eartip sizes is a meaningful differentiator from competitors that typically include only three. This broader range meaningfully improves the chance of achieving a solid acoustic seal across different ear anatomies, which directly impacts both sound quality and ANC performance.

The included eartips are made from fairly standard silicone that some users find slippery, making the fit feel less locked-in compared to memory foam alternatives. Replacement eartips are not prominently available from TOZO, so sourcing compatible third-party options requires some effort.

Suitable for:

The TOZO NC9 is genuinely well-matched to buyers who spend a meaningful chunk of their day commuting — subway riders, bus commuters, and office workers who want to dial down ambient noise without committing to a premium price. Fitness enthusiasts will find a lot to like here too: the IPX8 waterproofing is not a marketing asterisk but a real-world confidence booster for sweaty gym sessions or outdoor runs in unpredictable weather. Remote workers and students who frequently take calls in shared or noisy spaces will appreciate the multi-microphone setup, which handles voice isolation better than most earbuds at this price level. Travelers who prioritize battery longevity over everything else — especially those on long-haul flights or multi-day trips with limited charging access — will find the case stamina genuinely useful day-to-day. Budget-conscious audio hobbyists who enjoy tweaking their sound signature will also get meaningful utility from the app-based EQ flexibility, which offers more customization depth than is typical in this tier.

Not suitable for:

The TOZO NC9 is the wrong choice for anyone whose primary expectation is near-silence — buyers stepping down from Sony or Bose flagship earbuds will find the noise cancellation noticeably less thorough, particularly against high-frequency sounds like voices or sharp ambient noise. Critical listeners who favor acoustic, jazz, or classical music will likely find the bass-forward sound signature intrusive and the lack of treble clarity frustrating over time. If you have non-standard ear canal sizes and have historically struggled to find earbuds that seal properly, the fit gamble here is real — without a good seal, both audio quality and ANC effectiveness drop sharply. Gamers or anyone who needs to sync audio tightly to on-screen action should also look elsewhere, as there is no dedicated low-latency mode and the delay becomes distracting during fast-paced gameplay. Finally, buyers who want to stay paired to a phone and laptop simultaneously will hit an immediate wall, as multipoint connectivity is simply not on offer here.

Ease of Use

FAQ

Yes, these wireless earbuds pair over standard Bluetooth, so they connect reliably to both iOS and Android devices. You do not need a specific app to use core functions — music, calls, and ANC all work out of the box. The TOZO app, which unlocks EQ customization, is available on both platforms.

The IPX8 rating covers submersion in fresh water, so light pool use is technically within spec. That said, most users treat the rating as protection for sweat, rain, and accidental splashes rather than active swimming. Chlorinated pool water and repeated submersion cycles can degrade seals over time, so we would not recommend them as dedicated swim earbuds.

Honestly, there is a meaningful gap. The NC9 buds do a solid job of reducing steady, low-frequency ambient noise — transit rumble, HVAC hum, office background noise — but they cannot match the depth and breadth of cancellation that premium earbuds deliver. If you are stepping down from a flagship pair, you will notice the difference, particularly with voices and higher-pitched sounds.

In a typical home or office environment, the connection holds reasonably well up to around 10 to 15 meters through a wall or two. Beyond that, or in environments with heavy wireless interference, you may notice occasional audio stutters. The rated 20-meter range applies to open, unobstructed conditions.

This is a known frustration for some users. The app should retain your preferred EQ profile, but a recurring complaint across reviews is that settings occasionally reset to default after reconnecting — particularly on certain Android versions. It does not happen to everyone, but it is worth being aware of if precise EQ tuning matters to you.

No — these earbuds do not support multipoint connectivity, which means they can only maintain an active connection to one device at a time. Switching between your phone and laptop requires manually disconnecting from one and pairing to the other, which is a genuine inconvenience for people who regularly work across multiple devices.

You toggle between modes using the touch controls on the earbuds — a specific tap pattern cycles through ANC on, transparency mode, and ANC off. The exact gesture is covered in the user manual included in the box. You can also remap controls and switch modes through the TOZO app if you prefer a different setup.

TOZO does not make replacement tips prominently available through their own channels, but standard small-bore silicone eartips from third-party accessory brands typically fit. The included tips are a fairly standard size, so searching for universal silicone eartips compatible with in-ear headphones will usually turn up workable options.

The LED display is bright enough to read clearly in daylight but is not aggressively bright in a dark room. Most users do not find it disruptive at night, especially since it only activates when you open the case or check the battery, rather than staying illuminated continuously.

The 59-hour total is achievable, but only with ANC switched off throughout — which most people will not do if they bought the earbuds specifically for noise cancellation. With ANC running, total stamina drops to around 42 hours combined across earbuds and case, with each charge of the earbuds alone lasting roughly 10 hours. That is still a strong result for the category, but it is worth calibrating expectations around the ANC-on numbers rather than the headline figure.
