Excellent audio quality, effectiveness of active noise suppression, very high call quality, not bad comfort and... price! Ingredients of a recipe for all connoisseurs of high quality audio which lead to the TOZO NC7 being declared the best buy in the category to which it belongs. Let's discover them together in this complete review, which paves the way for a new, more concrete and streamlined style.

Let's start with the comfort which for these TOZO NC7 is decidedly high but the style must be liked, as the headphones in question are of the in-ear type, but still compact and light, without creating any discomfort even after long hours of use and above all they do not risk to fall. In any case, in the package you will find an additional 6 pairs of eartips of different sizes to better adapt them to your ear. The case is also small in size, allowing it to be placed in your pocket without any particular discomfort. Furthermore, the cover offers the hall sensor, allowing ultra-fast pairing of the headphones to your smartphone, without even removing them from their seat.
The earphones are IPX6 certified, therefore no problems with sweat or rain, while the controls are touch-based, i.e. with 1/2/3 touches or prolonged touch we can manage play/pause, skip the track, recall the phone's virtual assistant, control the volume and of course answer, reject or hang up a call. In reality, in the surface in contact with the ear we find an optical sensor that allows automatic play/pause, almost a rarity in this price range.
The audio quality is excellent, counting on a 7mm dynamic driver which is supported by TOZO's proprietary technology, the ORIGX 2.0, which optimizes the performance of the voice and the mid range, offering an engaging and realistic sound, as well as allowing to distinguish the smallest nuances of songs. You can't complain, whether it's medium or high bass, all frequencies are well present (powerful bass at 17 Hz and very clear highs with a frequency of 20 KHz).
There is also active noise cancellation, really effective and comparable to that of much more expensive headphones, reaching a suppression of up to 35 dB less and from my empirical tests I would say that you certainly can't complain about this function either. For the ANC we also have a function dedicated to wind suppression and those for indoors, ideal if you are in an environment with many voices around you that could be confused with yours. We also have transparency mode, which unlike ANC, amplifies background noise, an ideal function if you are in the car and want to stay alert for traffic.
For calls, we have a double microphone available for a single earpiece, allowing us to use them independently, but in this case the performance was not exactly at its best. In my tests, car noise is not properly suppressed and sometimes the interlocutor could struggle to hear us, but overall the voice always sounded clean, never muffled or metallic.
The autonomy that I measured during my tests is around 18 hours with a single charge, but at 50% volume, while if we increase the level this will drop to around 11/12 hours, a value which drops to around 10 hours if we enable the noise cancellation. The maximum autonomy, again if we take a volume of 50% as a value, reaches up to 72 hours, counting on a 500 mAh case battery, while for the headphones we have a 70 mAh unit. Charging takes place either wired via Type-C cable or wirelessly, with a duration of approximately 2 hours. Finally, the connection to the smartphone occurs via Bluetooth 5.3 with excellent connection stability while the supported codec is the classic AAC/SBC.
Using the application you can then customize the gestures, customize the equalization and set the active noise cancellation even on a customizable level, up to 10 levels, as well as update any firmware that the company may release over time.
Speaking of price, they cost 59,99 euros in the list but at this precise moment in which I am writing the review of the TOZO NC7, you can find them on Amazon at the price of 47,99 euros and at this price it is difficult to ask for more.
