The TOZO NC2 are well-built truly wireless headphones. They have over 10 hours of continuous battery life and come with a case that holds roughly three extra charges. Their sound profile is slightly v-shaped, so your music has extra rumble and punch, while instruments and vocals sound present and bright. Unfortunately, they lack an EQ you can use to customize their sound. Unlike the TOZO NC9 Truly Wireless, they have a disappointing and quite ineffective active noise cancelling (ANC) feature, especially when it comes to blocking out bass-range noise like rumbling engines.
The TOZO NC2 are okay for mixed usage. They're decently comfortable and have a continuous battery life of more than 10 hours, so they should get you through a long commute or day at the office. They're also breathable and have a decently stable fit, although you may need to readjust them every once in a while. Unfortunately, their ANC doesn't offer much better performance than their passive noise capabilities, so they aren't ideal if you want to block out the sound of rumbling engines or background chatter. Fans of neutral sound may not like their bass-heavy sound profile, and they don't have an EQ.
The TOZO NC2 are alright for neutral sound. Their sound profile is fairly neutral but slightly v-shaped, so your music has extra rumble and punch, but sibilants like cymbals may be a bit piercing. They have decently consistent audio delivery but it may vary depending on their fit, seal, and positioning. Unfortunately, they don't work with a companion app and lack an EQ, so there's no way to adjust how they sound.
The TOZO NC2 are decent for commuting and traveling. Their battery life lasts for roughly 10 hours of continuous use and they come with a portable case that holds about three extra charges. They're lightweight, comfortable, and don't leak much audio, so your music shouldn't bother people around you, even if you're listening at high volumes. However, their ANC feature is disappointing, as it doesn't block any noise in the bass range, which includes sounds like the rumbling of bus and plane engines.
The TOZO NC2 are great for sports and fitness. Like most in-ears, they're very portable and breathable. They have good, easy-to-use touch controls, so you can skip tracks or change the volume without pausing your workout. They even have an IPX6 rating for water resistance, although we don't test it currently. While they have a decently stable fit, you may need to readjust them during more intense workouts. On the plus side, they come with six different tip sizes, so you can find the best fit for you.
The TOZO NC2 are okay for office use. Their battery lasts for roughly 10 hours of continuous use, which should be more than enough to get you through a workday, and they're decently comfortable. Unfortunately, their ANC has a disappointing performance and doesn't block out much noise. On the plus side, they don't leak too much audio, so you shouldn't bother your coworkers even if you're listening to music at a high volume.
The TOZO NC2 are Bluetooth-only headphones and aren't compatible with PS4, PS5, or Xbox consoles. They can be used with Bluetooth-enabled PCs, but their latency is too high to be suitable for gaming.
The TOZO NC2 are truly wireless headphones that cannot be used wired, so they aren't suitable for wired gaming.
The TOZO NC2 are sub-par for making phone calls. Their microphone makes your voice sound muffled, and it has a mediocre noise handling performance, so if you answer your phone in a noisy environment, it may be hard for the person on the other end to hear you. Also, their ANC feature doesn't do a good job of blocking out noise, so you may have a hard time hearing the person you're talking to.
The TOZO NC2 are decently comfortable. They feel light and using their touch controls shouldn't hurt your ears. Unfortunately, they move around a bit and you may need to readjust them every so often. Luckily, they come with lots of different sizes of earbud tips, so you can choose the best fit for you.
The TOZO NC2 have good controls. You can tap the left earbud once to switch between ANC mode and Ambient mode, which allows you to hear sounds around you. Tapping it twice skips back to the previous track, and holding it turns the volume down. To turn the volume up, hold the right earbud. You can also tap the right bud once to play/pause, and tap twice to skip forward. When you receive a phone call, you can tap either earbud once to answer, and hold either one to hang up or reject the call. You can also activate the voice assistant by triple tapping either earbud. In mono mode, you can also play/pause by tapping either earbud.
The controls are easy to use once you've learned them, although the touch surfaces could be more responsive. Conveniently, there are voice prompts when you pair the headphones with a device or switch between ANC mode and Transparency mode, as well as beeps when you change the volume or track.
The TOZO NC2 are remarkably breathable, like most in-ear headphones. Their design doesn't trap a lot of heat, so you shouldn't sweat more than usual while wearing them.
The TOZO NC2 are remarkably portable, like most truly wireless in-ears. They're very small and light and come with a compact carrying case that should fit easily into most pockets and bags.
Update 04/30/2021: We originally reported the wrong case measurements. We have corrected and updated these measurements. The scoring of this box hasn't changed.The TOZO NC2 come with a good, hard plastic case that you can use to charge the earbuds. It's more compact and less rounded than the case for the TOZO NC9 Truly Wireless, and should easily fit in most pockets and bags. There's a pairing button on the back and it has four LED lights on its front that indicate how much battery life the case has left.
The TOZO NC2 Truly Wireless have good build quality. They're lightweight and made of glossy plastic that feels solid, although the squishy earbud tips seem a little less durable. That said, they should survive some accidental drops and minor bumps without too much damage. They also have an IPX6 rating for water resistance, although we don't currently test for this.
The TOZO NC2 are decently stable. They don't have stability fins and may fall out of your ears even if you're not moving around very much. Luckily, they come with several differently-sized tips, so you can adjust how they fit depending on your ear size.
The TOZO NC2 have a slightly v-shaped sound profile. The bass range is overemphasized, so mixes have extra thump and punch, but some may find their music sounds muddy or boomy. Sibilants like S and T sounds are also a bit piercing. They don't come with an app that gives you access to an EQ or presets.
The TOZO NC2 have decent frequency response consistency. Their bass and treble delivery may vary depending on how well they fit in your ears, as well as their seal and positioning.
The TOZO NC2 have good bass accuracy. The bass range is overemphasized, so mixes sound thumpy and punchy, which should please fans of genres like EDM and hip-hop. Some listeners may find they sound muddy or boomy, although their sound profile isn't as bass-heavy as that of the TOZO NC9 Truly Wireless.
The TOZO NC2 have excellent mid accuracy. The range is very balanced and neutral. There's a small dip in the mid-mid range that nudges lead instruments and vocals back, but they still sound present and clear.
The TOZO NC2 have great treble accuracy. The low-treble is somewhat underemphasized, which veils instruments and vocals a little. The overemphasis in the mid-treble helps lead instruments and vocals sound present and bright, but also adds harshness to sibilants like S and T sounds and cymbals.
The TOZO NC2 have great peaks and dips performance. There's a dip in the mid-mids that nudges lead instruments and vocals back, while a peak in the high-mids adds harshness. A small dip in the low treble may hurt the comprehensibility of vocals and instruments, but it shouldn't be overly noticeable. There's also a peak in the mid-treble that makes sibilant sounds, like cymbals, a bit piercing.
The TOZO NC2 have excellent imaging. The group delay falls below the audibility threshold, resulting in a tight bass and transparent treble reproduction. Also, the L/R drivers of our test unit are well-matched in phase, frequency, and amplitude response, so objects like footsteps and voices are accurately placed within the stereo image. However, these results are only valid for our test unit, and you may have a different experience.
The TOZO NC2 Truly Wireless have an awful passive soundstage, like most in-ear headphones. Because of their design, they don't interact with your outer ear, so sound seems to be coming from inside your head instead of all around you. Also, because of their closed-back design, they sound less open and spacious than open-back headphones.
The TOZO NC2 have a great weighted harmonic distortion performance. All frequencies fall within good limits, resulting in clear and pure audio reproduction.
These are the settings we used to test the TOZO NC2 headphones. Our results are only valid when using these settings.
These headphones have a disappointing noise isolation performance. The headphones block about as much noise passively as they do with the ANC feature on. Unlike the TOZO NC9 Truly Wireless, their ANC doesn't out block bass-range noise, like the rumble of bus and plane engines. It only sort of isolates you from mid-range noise like background conversations or the hum of an A/C unit.
Note: The ANC feature can't be turned off, so we tested the headphones' passive noise isolation performance by turning them completely off. If you want to listen to audio without the ANC on, you can switch to 'Transparency' mode, which is supposed to allow you to hear your surroundings. Unfortunately, there isn't much audible difference between the two settings, except that ambient noise sounds more piercing and unnatural when the headphones are set to 'Transparency' mode.
The TOZO NC2 have great leakage performance. They don't leak very much sound, and what noise does escape sounds thin. It shouldn't bother people around you very much, even if you listen to your music at high volumes.
The microphone's recording quality is disappointing. Recorded speech sounds muffled, dull, and lacks detail.
The microphone has a mediocre noise handling performance. When you're on the phone, the person on the other end may have trouble hearing you if you're in a noisy environment, like a busy street or subway station.
These headphones have a decent battery performance. They have a continuous battery life of more than 10 hours, so they should get you through a full workday. Their case holds roughly three additional charges, so their total battery life is more than 40 hours, which is long for truly wireless headphones and much longer than the battery life of the TOZO NC9 Truly Wireless. They also recharge quite quickly, taking a little less than an hour and a half. Conveniently, you can use one earbud while the other charges. However, battery performance can vary with real-life use, so your experience may be different.
The TOZO NC2 have adequate Bluetooth connectivity. They don't support NFC pairing or multi-device pairing and have quite a lot of latency with PCs, so they aren't ideal for watching videos or gaming on your computer. However, they have lower latency on iOS and Android devices. Also, some apps seem to compensate for latency, so you may get different results with real-life use.
These truly wireless headphones can't be used wired. They come with a USB-A to USB-C cable to charge the case.
These headphones are Bluetooth-only and can't be used with PS4 or PS5 consoles. You can connect them with your computer if it's Bluetooth-enabled, but because of their high latency, they aren't recommended for PC gaming.
These headphones come with a charging case that stores roughly three extra charges. You can charge it with the included USB-A to USB-C charging cable. It also supports wireless charging but doesn't come with a wireless charger.
The TOZO NC2 are available in one color variant: 'Black.' You can see the label for the unit we tested here. If your headphones are different or you come across another variant, please let us know in the discussions so we can update our review.
