This TOZO NC7 review covers everything from sound quality to design, providing a complete analysis of these earbuds. Furthermore, we compare the NC7 with its sibling models, the NC9, NC7 Pro, and NC2, to help you understand properly. Don’t miss it.

Sound quality

It had excellent audio quality. I use of its R&B sound effect. There is no difference between it and a professional sound system when I use it. Every bit and base is very clear and strong. It is a powerful concert sound system. When I listen to music with it, I feel like dancing. To keeping myself controlled, it is like a struggle.

When I compare it to airports, there is no discernible or measurable difference in sound quality. Every single sound is delivered clearly. From the higher to the lower frequencies, they both produce them perfectly. Hearing clearly, I discovered a steel lower and tired sound.

The TOZO sound app is used to control the TOZO NC7. This app allows you to control active noise cancellation and change the sound effect. There are so many sound effects that can be used while listening to music. I tried all of the sound effects, and to summaries, TOZO can satisfy any user who wants to listen to soft music or DJ music.

Battery

Is the most important thing when you want to go anywhere or journey. More offer it gives the opportunity of long time continuously.

Playtime (Battery Life) & Durability

Every earbud has 70mAh battery that provides continuous 12 hours of playtime. The charging case has 500mAh capacity. So, you can charge the earbuds more than three times.
I have been experimenting with it for the last 63 days. Let me publish the battery backup result on a single charge –

On ANC Mood

You know that ANC (Active noise cancellation) works by capturing environmental sound using a mic, then analyzing noise, and finally making opposite-direction noise, which is called anti-noise sound. This anti-noise sound wave will cancel out the noise.

The mic and additional function work in this mode; battery usage is at the highest level. After that, it gives me an average of 10 hours and 30 minutes of battery backup on a single charge.

On Transparent Mood

In the transparent mode, earbuds ensure you can listen to every sound of your surroundings clearly as you can normally listen. But as the earbuds block your ear channel, the sound can not go inside properly. So passive noise cancellation works. To solve that, it uses its mic to capture soundings sound. Then it enhances by its speaker. So you can easily hear everything.

I got an average of 12 hours of battery backup in this mode.

On Normal Mood

In this Mode, the mic is fully turned off. For this, I got longer battery backup than I expected. It gives me approximately 15 hours of continuous service, 1 hour less than the company claim. I am just surprised!

Charging time

I have already changed more than 12 times. I have charged each time by connecting it to the USB port of my laptop. Laptop provides slow charging. After that, it fully charged within an average of 2 hours and 10 minutes. It took a maximum 2 hours 50 minutes, minimum 1 hour and 35 minutes to become fully charged. The company Claimed it may take about 2 hours for full charging. This variation may be caused by discharging level.
Though I don’t charge with a fast charger, it’s simple to say that it can be more quickly charged by fast charger.

Are they comfortable?

The TOZO NC7 earbuds are stylish and lightweight. It is designed as the ear shape, with multiple sizes of ear tips that provide a comfortable fit for all users. The black color gives an extra layer of beauty. Over I loved the design and comfortability of it. Though I face comfortability issue when I used it for long time continuously.

Noise management

It provides Hybrid active noise cancellation to the user. For controlling noise cancellation TOZO Sound app has 6 different options. You can select any one according to your need.

Noise Cancellation (ANC Mood):
Hybrid Active noise cancellation works in this mood. It the highest power of noise cancellation. In this mood, Active noise cancellation and passive noise cancellation works together. And provides almost no noise entry.

Transparent Mood:
In this mood, both active and passive modes are turned off. When you’re listening to music with ANC mode, if someone says something to you, you won’t be able to hear it properly. This mode is designed for situations like that, allowing you to hear them without excluding them.

Normal Mood:
In this mood, ANC is off but due to blockage of your ear cannel, passive noise cancellation works. It reduce noise but not as effective as ANC.

Custom Pattern:
TOZO gives the opportunity to its user, to control noise cancellation level. This level is directly related to the battery backup or playtime. Because if you use higher level of noise cancellation, then earbuds mic will turn on. Microphone record the noise and an anti-noise wave produced by the speaker. Such this way, noise cancellation works.

How well do they fit?

TOZO very cleverly handles fitting and comfortability issues. They designed so clearly that earbuds can be fit any person’s ear. They make it in similar shape to the external ear. So, it is perfectly set on the ear. I have checked by running, jumping, and also sleeping.

On running, there is no issue detected. I got the same condition as I was set. But on jumping, after doing 8 high jumps, it was fallen. It is enough to say its fitting is perfect. Normal earbuds can’t stay in the ear after maximum 2 or 3 jumps. Thus it properly fitted to my ear.

Moreover, it included 5 extra ear tips in different sizes. This help to perfectly fit your ear. So no worry about my ear and your ear being different. Just use perfect-fitting ear tips.

Water management

With the IPX6 rating, it can ensure that it will not leak from 1.5 meters to 30 meters underwater, and the performance will not be affected. It’s easy to say light rain, heavy rain, and sweat can not affect its performance. It is properly waterproof and sweatproof.
To be honest, I am personally not tested underwater. But on my checkup, the design was water leakage free.
