The TOZO NC7 Truly Wireless are budget-friendly noise cancelling truly wireless in-ears. Like the TOZO NC9 Truly Wireless, you can cycle between their ANC feature, which offers impressive noise isolation, and Transparency Mode, which lets in some ambient sound. Their slightly excited sound profile adds a little extra thump to your audio while making sibilants bright, but there isn't any way to customize their sound more to your liking.
The TOZO NC7 are adequate for neutral sound. They have a somewhat excited sound profile that adds a little extra thump in the low-bass while nudging vocals and lead instruments towards the back of the mix. Also, sibilants like S and T sounds are piercing, which can be painful to listeners who prefer a more neutral sound. Unfortunately, they don't have any sound customization options.
The TOZO NC7 are very good for commute and travel. Thanks to their ANC feature, they can block out background noises like bus and plane engines as well as the sounds of commuters chatting around you. They're portable and decently comfortable, though some listeners may not enjoy their deep in-ear fit. Also, their eight-hour continuous battery life may not last through long international flights.
The TOZO NC7 are impressive for sports and fitness. These well-built, portable in-ears have a breathable design, so you don't sweat more than usual while wearing them. They're stable enough to stay in your ears during light workouts, but they don't have stability fins, so they may fall out during more intense exercises. Also, they sit a bit deep in your ears, which may not be comfortable for all listeners.
The TOZO NC7 are fair for office use. These headphones offer great noise isolation, so you aren't distracted by the sounds of coworkers talking nearby or the hum of AC units. They also don't leak a lot of audio, so you can crank up the volume without bothering your coworkers. Unfortunately, their deep in-ear fit may not be comfortable for everyone, and their eight-hour continuous battery life may not be suitable for long days at the office.
The TOZO NC7 aren't compatible with PlayStation or Xbox consoles. They can be used with Bluetooth-compatible PCs, but their latency is likely too high to be suitable for wireless gaming.
The TOZO NC7 are wireless-only headphones that aren't suitable for wired gaming.
The TOZO NC7 are reasonable for phone calls. Their integrated microphone has a decent recording quality, so whoever's on the other end of the line can understand you, but your voice may also sound a bit thin. The mic also struggles to separate your voice from background noises, so it isn't really suitable for making calls from noisy settings. Fortunately, their ANC feature can help block out background noise so you can focus on your call.
The TOZO NC7 come in 'Black', and you can see the label for the model we tested here.

The TOZO NC7 are truly wireless in-ears that offer impressive noise isolation thanks to their ANC feature. Like the TOZO NC9 Truly Wireless, you can't turn the ANC off entirely, but you can switch them to Transparency Mode, which lets in some ambient noise to help you stay aware of your surroundings. That said, their slightly excited sound profile may not be ideal for all listeners, and they don't have any sound customization features.

The TOZO NC7 Truly Wireless are better headphones than the TOZO NC9 Truly Wireless. The NC7 have a more balanced sound profile compared to NC9, especially in the bass range, so they're more suitable for fans of neutral sound. Also, they leak less audio, and they have longer continuous battery life. Their charging case also supports wireless charging, which is handy. That said, the NC9's charging case offers around one extra charge.
The TOZO NC7 Truly Wireless are better for most uses than the TOZO NC2 Truly Wireless. The NC7 have an impressive ANC feature, a more stable fit, and a better microphone recording quality. On the other hand, the NC2 have a longer continuous battery life and their case holds more extra charges. They're also smaller and less bulky than the NC7, which some may prefer.
Depending on your listening habits, you may prefer either the TaoTronics SoundLiberty 94 Truly Wireless or the TOZO NC7 Truly Wireless. The TOZO have a more balanced sound profile, and they have longer continuous battery life. However, the TaoTronics offer better noise isolation, and they leak less audio.
The Mpow X5 Truly Wireless and the TOZO NC7 Truly Wireless are similarly-performing headphones, so depending on your listening habits, you may prefer one over the other. The Mpow are more comfortable, and they have a slightly better noise isolation performance. However, the TOZO have a more balanced sound profile, especially in the bass range, and their continuous battery life is a bit longer.
The TOZO NC7 Truly Wireless are better headphones than the Sony WI-SP600N Wireless. The TOZO have a more balanced sound profile compared to the Sony's bass-heavy sound. They also have better noise isolation, especially against bass-heavy background noise, and their continuous battery life is longer. However, some listeners may prefer the Sony's neckband design, and they have more sound customization features thanks to the graphic EQ and presets in their companion app.
The TOZO NC7 are truly wireless in-ears with a similar design to the TOZO NC9 Truly Wireless and the TOZO T12 Truly Wireless. They're mostly made of matte plastic, and they have a glossy plastic outer ring. Their shape is rounded, which some listeners may find a bit bulky.
The TOZO NC7 are decently comfortable. They come with lots of different sizes of earbud tips to help you get the best possible fit. However, they're a little bulky, and they sit a bit deep in your ear, which may not feel comfortable for everyone. Fortunately, pressing their touch-sensitive controls doesn't push them further into your ear.
The controls are good. Tapping the left bud once lets you switch between ANC Mode and Transparency Mode, which lets in some ambient noise so you can hear people talking around you. However, you can't turn the ANC off entirely. Tapping the left bud twice skips back to the previous track, and holding it turns the volume down. You can tap the right bud once to play/pause your audio, twice to skip to the next track, and hold it to turn the volume up. If you get a phone call, you can tap either bud to answer and hold either bud to end or reject the call. Pressing either bud three times activates the voice assistant. Overall, the controls are responsive and there's lots of audible feedback, including voice prompts and beeps when you reach min and max volume.
The TOZO NC7 have a good build quality. Like the TOZO NC9 Truly Wireless, they're mostly made of plastic, with a matte finish on the exterior and a glossy finish on the interior. They're even rated IPX6 for water resistance, though we don't currently test for this. However, the earbud tips seem like a potential weak point over time.
The TOZO NC7 have a slightly excited, V-shaped sound profile. There's a little extra emphasis in the low-bass that adds some thump to your audio, while vocals and lead instruments are nudged slightly towards the back of the mix. Sibilants like S and T sounds are bright, but some listeners may find that they sound a bit piercing. There aren't any sound customization features, so you can't adjust their sound.
The TOZO NC7 have impressive bass accuracy. The low-bass is overemphasized, so you really feel the deep thumps and rumbles in your audio, which is ideal for fans of bass-heavy music like EDM and hip-hop. The rest of the range is quite balanced, so the punch and fullness in the bass is present without becoming overwhelming.
The mid accuracy is very good. The range is pretty balanced, but the mid-mids and high-mids are slightly underemphasized. As a result, vocals and lead instruments are nudged slightly towards the back of the mix, and they can be weak or distant.
These headphones have decent treble accuracy. The slightly underemphasized low-treble can hurt the comprehensibility of vocals and lead instruments. However, the peak in the mid-treble makes sibilants, such as cymbals or S and T sounds, piercing and painful.
These headphones have a decent peak and dips performance. The peak in the low-bass adds thump to your audio. The dips in the mid-mids and high-mids can nudge vocals and lead instruments towards the back of the mix, and they can sound weak or distant. The peak in the mid-treble makes sibilants like cymbals piercing and painful.
The TOZO NC7 have excellent imaging. Their weighted group delay falls below the audibility threshold, resulting in a tight bass and transparent treble. 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 and localized within the stereo image. However, these results are only valid for our test unit, and your experience may vary.
These headphones have an awful passive soundstage performance. Due to their in-ear design, they bypass the outer ear, which is one of the key factors in creating a large and out-of-body soundstage. As a result, sound seems like it's coming from inside your head, rather than from speakers placed all around you. They also have a closed-back design, so their soundstage isn't perceived to be as open as that of open-back headphones.
These are the settings we used to test these headphones. Our results are only valid when using these settings.
The TOZO NC7 have impressive noise isolation. With their ANC turned on, they can block out background noises such as bus and plane engines as well as voices and the hum of nearby AC units.
Note: You can't turn off the ANC feature on these headphones, though you can cycle between it and their Transparency Mode, which lets in some ambient noise. We tested these headphones completely off to measure their passive noise isolation performance for comparison.
The microphone has a middling noise handling performance. It struggles to separate your voice from background noise, so the person on the other end of the line may have trouble understanding you, even if you're only calling from a moderately noisy setting.
The TOZO NC7 have an okay battery performance. Though they have an advertised battery life of 10.5 hours, in our tests, they lasted for just over eight hours off of a single charge. However, battery life can vary depending on usage, so your experience may vary. You can also listen to audio through one bud while the other is charging, which is handy.
Update 03/03/2022: These headphones were updated to Test Bench 1.5 and their latency values have changed. Our new test bench uses an average of three measurements instead of one. We have updated our text to better reflect these new results.
The TOZO NC7 have fair Bluetooth connectivity. They don't support NFC pairing, and you can only pair them with one device at a time. Their latency on PCs as well as on iOS and Android devices is also too high to be suitable for gaming. Keep in mind that some apps compensate for latency differently.
The TOZO NC7 come with a charging case that around two extra charges. You can charge it using the included USB-C cable, and it also supports wireless charging.
