TOZO TONAL FITS (T21) – The best semi in-ears with an excellent quality/price ratio

When you buy a pair of headphones, you always think that it is the latest pair but with the continuous technological evolution, in reality we always find ourselves having at least a spare pair, especially when we find the right offer. It goes without saying that the difference with Apple's products has become increasingly narrow over time, finding really low-cost products on the market that don't make you regret the expense and today I bring you one of these products, namely the new TOZO Tonal Fits (T21) which for less than 40 euros will sound sublime in your ears and in your wallet.

In reality, as far as the unboxing experience is concerned, I would go very quickly as inside the package, we only find the product itself, manuals and power cable, so no rubbers because the T21s are semi in-ear in nature. In any case, it is undeniable that as soon as we have the TOZO Tonal Fits in our hands, the feeling of having purchased a Premium product will shake your thoughts. TOZO's audio solution is in fact made of high quality plastic materials, in fact the matte surface of the case has an anti-fingerprint treatment but above all the small display is satisfying which allows you to keep an eye on the remaining life of the battery and of the compartment of charging and of the headphones themselves. Available in different colours, black is the color we chose for the test and is elegant and sporty at the same time.

The shape of the case is classic but contained in size and the slightly rounded profiles create absolute comfort even when we place the box inside a pocket of very tight trousers. On the back we find the Type-C port for charging, but this is not the only way to recharge the product, but I'll talk about it later in the chapter dedicated to autonomy. The cover incorporates the hall sensor for immediate coupling of the T21 to the device they are associated with, without even removing them from their seat. Perhaps the hinge needed to be slightly reinforced as with a small shake the lid closes immediately.

TOZO Tonal Fits are headphones with a semi in-ear design, so we do not have silicone rubber tips in contact with the ear, but the isolation from the outside world is still good, but not marked while remaining alert to what is happening around us. Very small dimensions such as the stem, short and poco invasive on the face. The ergonomics and fit of the headphones are at the top and for those who fear that the semi in-ear design does not guarantee stability, I assure you that once worn they never slip, even if we carry out sporting activities, also counting on an IPX8 certification. The trick is to rotate them slightly outwards once inserted into the ear canal.

Semi in-ear design means zero stress and zero pressure, allowing you to fall asleep with the TOZO Tonal Fits on. Each earphone, obviously, has a touch control area that allows you to move between the various functions of the headphones simply by touching the interested area or by making a long press. We can therefore manage the volume control, play/pause, skip the music track and recall the device's voice assistant with a single/double/triple touch or long press and of course reject, hang up or answer a call.


Ok, a book is not judged by its cover but by its content, but in the case of the TOZO Tonal Fits we have quality not only aesthetically but also in the reproduction of music, films, podcasts and calls in general, thanks to large 14,2 mm dynamic drivers and dual microphone for noise cancellation in call mode (ENC). Without going into too many technicalities I can state that the T21s perform well in the reproduction of any musical genre, with a good presence of bass in balance with the medium-high tones. However, we can adjust the equalization curve via the companion app or draw on 16 audio presets, to obtain a sound that is even more suited to the type of listening you are doing.

In addition to the exceptional audio quality when listening to music of all genres, the TOZO Tonal Fits also stand out positively during calls. I repeat that they are equipped with a double microphone, but in addition TOZO has implemented an algorithm which, through artificial intelligence, allows us to minimize background noise and improve voice clarity, features that we usually only see implemented in models costing over 100 €. Also worth mentioning is the presence of the latest generation Bluetooth 5.3, which guarantees very low latency, which makes the product in question also suitable for gaming use for the most demanding users.

APPLICATION (Android and iOS)

One thing that should not be taken for granted is the presence of an application that allows you to manage some parameters of our headphones. The app is available for both Android and iOS users and is guaranteed to work on both systems. Very fast pairing but above all with the TOZO app we can adjust the audio parameters and customize the touch controls on the individual earphone but also update the firmware, but a truly unique gem is that of being able to play white noises in the background to help you fall asleep. On the other hand, the TOZO Tonal Fits are so comfortable that you can actually fall asleep with them on.


With TOZO's T21s you can say goodbye to the worry of continually recharging the battery. In fact, the Tonal Fits boast a combined battery life between headphones and case of up to 44 hours, counting on a battery with a capacity of 500 mAh. In detail, each earphone offers a playback autonomy of approximately 10 hours, with a playback volume of around 70/75%, because at maximum volume it drops to around 7 hours. I also noticed that prolonged use of the headphones during calls tends to drain them more than during music playback, but the results do not differ significantly from the autonomy mentioned above. The positive thing to point out is that in addition to classic charging, therefore via USB Type-C cable, you can also take advantage of wireless mode, something not so obvious in a price range of less than 40 euros.

In any case, all this data shows us how the battery life offered by many wireless headphones on the market is lower than what TOZO has managed to bring with this model, which has very few competitors in terms of autonomy, especially at the same price.

The TOZO Tonal Fits (T21) are available on Amazon with a price of less than 37 euros, a figure for which it is difficult to buy something better, in fact we often find products from more well-known brands but with poor performance, in practice we only pay for the brand . As far as I'm concerned, the T21s despite the lack of noise cancellation (impossible to have at these figures) stood out and are a product that I would recommend to those looking for a balance between style, functionality and audio quality. Their elegant design, comfortable fit and long battery life make them versatile companions for everyday use.
