A good pair of wireless earbuds is vital, especially if you enjoy listening to music or watching movies while traveling. Today, we will examine and review the TOZO Tonal Fits T21 to comprehensively discuss the selection of high-quality buds. They have impressive quality, also known as TOZO T21, and I have reviewed other TOZO earpieces in the past. I am a true fan of these buds and their performance because they truly provide value for money. Their extraordinary features, exceptional audio, and build quality make these a good buy.
My experience with this pair of headsets over the last few weeks has been mixed. You can receive a pair of earphones, a Type-C cable, a user’s guide manual, and a warranty card in the box. The semi-in-ear design is very user-friendly; you can slip them into the ear, and they sit well there without disturbance. I had no issues using the earphones in my ears for long hours, even while not listening to music. The feel of the earbuds is also compact. There was no use of any insubstantial material to build this product, ensuring its durability and long-lasting performance.
They feature 10 hours of playtime with a single charge, and the charging case offers another 44 hours. Charging the case fully via the USB Type-C port takes around two hours, and the buds take 1.5 hours to charge fully. The charging case also supports Qi-wireless charging; you can place it on a wireless charger, but it takes additional time to charge fully. The Environmental Noise Cancellation allows you to take clear calls with reduced distracting sounds. The best part is that they have an IPX8 water-resistant rating, which means you can use them in any weather condition worry-free.

Design and Comfort
TOZO Tonal Fits T21 earpieces have simple packaging, with an external box featuring an image of the earphones. The package includes a pair of earbuds, a charging case, a USB Type-C cable, the user manual, and a warranty card. They are available in four colors: black, blue, green, and red. The compact design of the T21 makes it comfortable to wear for an extended period. Their design closely mirrors the classic Apple AirPods, characterized by a semi-in-ear, stem-style form without silicone tips
Branding is printed on the stems of the buds, which have a semi-in-ear design. Some people find the in-ear design uncomfortable, so a semi-ear design suits them. It doesn’t block out your ear canal, is healthier, and lets a bit more airflow. So, you have a minimal chance of infection or any ear fatigue. They are made of plastic with glossy accents and don’t feel cheap. The grip is a bit off and feels slippery in my hands, but it’s more or less comfortable, depending on your ear design.

The carry case is made of plastic and features an upright flat base design, making it easy to place on a surface. Moreover, the narrow and slim profile makes it ideal for sliding into a small jeans pocket. The Type-C charging port is present on the rear side of the case, while the front side features a digital display to indicate the battery percentage. When you close the case lid, this LED display will automatically switch off after three seconds. The carry case lid features a hinge that slightly vibrates and shuts magnetically. The charging case dimensions are 58.4mm x 43.6mm x 27.1mm, weighing 46g when both earbuds are inside.
Sound Quality
I judge them based on how they produce the three frequencies that make up any sound: the highs, the mids, and the lows. They are okay starting with the treble response or the higher frequencies. Other truly wireless earbuds, including those from TOZO, have demonstrated superior performance in my experience. I think Tonal Fits has a solid volume, and I can get a comfortable listening volume at around 40%. The impressive thing about this product is that the volume gets loud at 55% to 60%, which is fantastic. When placed against the SoundPEATS Air3 Deluxe HS, the T21 holds its own, offering a similarly clean and open sound.
T21 has 14.2 mm Dynamic Drivers for music lovers, delivering clear, deep sound for an unparalleled music experience. It is common to think that earbuds with ear tips have a good base and sound quality, but these buds offer a great base even without ear tips. Remember that I used the base Plus in Equalizer Mode; even this shape provides a great music experience. The singer’s voice quality, the treble, the bass, and everything else are on point. If you want good quality music and don’t like earphones with ear tips, I highly recommend the Tonal Fits.

They stand out in the crowded market of budget-friendly audio devices not just for their affordability but also for their impressive performance. The more significant driver produces a richer sound with deep bass and more transparent highs. It features a semi-open design, contributing to a more natural listening experience and helping expand the Sound Stage. Another significant aspect of T21’s performance is its ability to maintain clarity and detail at several volume levels. This is achieved through meticulous driver tuning to balance the bass response with the mid and high frequencies, ensuring the bass is powerful without overshadowing the mids.
TOZO App and Touch Controls
Installing the TOZO app on your smartphone lets you add your device to the earpieces. Open the app and tap the add button with the plus sign, then select ‘TOZO Tonal Fits,’ and the earpieces will connect with the device. You will need to remove the earpieces from the case to activate the rest of the functions. Afterward, the app will show both buds’ remaining settings and battery percentage. You may receive OTA updates as I received them; completing the update process took 5 to 10 minutes.
The control options are on the control tab, where you can customize the single-tap, double-tap, and triple-tap functions of the left and right earphones and the long-press function. A single tap on the left will play or pause the music, and a double tap will start the music from the beginning. Triple-tap on the left to activate Siri and decrease the volume level. Press and hold on to the touch area.
Now we have the right earpiece, and you can tap it once to play or pause the media. A double tap on the touch surface will play the next track; like the left one, a triple-tap will activate Siri. Tap and hold on to the touch area to increase the media’s volume, which is missing in many others. These are the default settings, and you can change them by tapping on each option in the app.
While listening to music, tap once to answer an incoming call and long-press for two seconds to reject it. If you are already on a phone call, press for two seconds to hang up or end the call. The app offers 16 equalizer modes; you can customize and save a new one with a different name.
IPX8 Waterproof Rating
TOZO Tonal Fits T21 has an IPX8 waterproof rating, which means it can withstand rain outdoors for a while. You can also clean them with fresh water when dirty or smeared without losing their durability. These earphones can resist fresh water spills from the kitchen or under ordinary circumstances. It is recommended to avoid making or receiving calls when the microphone or speaker is wet because the audio sound may be muffled, affecting the call clarity.
TOZO tested the waterproof quality in a controlled environment and has been proven to be waterproof in certain situations. You can fully submerge them up to 1.5 meters for 30 minutes. It is important to note that the Bluetooth connection will instantly be interrupted if you dive underwater. My testing validates that you will lose the Bluetooth connection after submersion. However, my testing found no significant issues related to waterproofing by dipping just below the surface.
If you face extreme environments or weather conditions, whether you have a tough workout or are caught in a storm, this rating will protect your earpieces from water. IPX8 water resistance ensures higher durability and protects against dust and moisture. The rating is a perfect blend of technology and aesthetics and is a barrier against an intense environment. Its waterproof protection level reveals TOZO’s determination to deliver the product smoothly and survive challenging environments.
Playtime and Battery Life
With its solid structural design, TOZO Tonal Fits T21 provides durability for everyday usage. It has an extra-long battery life, with a continuous 6 hours of playback and a remarkable 44 hours with the case. Thus, the total playtime is around 50 hours, enough for a busy routine. The playback time may vary depending on the features you use and the external environment. Likewise, you can get the best playback by keeping the volume to around 50%. Raising the volume to the maximum range may decrease the listening duration and damage your hearing.
The charging case also features a convenient digital display that helps you stay informed of the remaining power. It shows the battery status of the earbuds and the case. The case’s battery is 500 mAh, which gives the buds more than seven additional charges. You can charge the case via the Type-C charging cable available in the package and with the Qi-compatible wireless charger.
With the cable, you can charge the case in around 2 hours, and the buds take around 1.5 hours. It gave up to 40 hours during my practical testing, slightly lower than the company claimed. As discussed, the product’s lack of fast charging is a drawback in today’s fast-paced world. Active Noise Cancellation is absent in Tonal Fits, thus not impacting the total playtime. However, environmental noise cancellation (ENC) is present, which helps make calls clearer by removing unwanted background noises. The background call noises were about 85% to 90% compared to non-ENC earphones.
Bluetooth and Connectivity
TOZO Tonal Fits T21 has Bluetooth V5.3 and an advertised range of 10 meters, which I found correct. It works fine even when I cross the specified range. Remove the buds from the case pairing via Bluetooth and perform a Bluetooth search on your device. Once you’ve paired them with your device, the earpieces will connect automatically when you open the case, making them super convenient.
Like TOZO T12 earphones, the latest Bluetooth version ensures better playback of higher-quality formats, such as 265 kbps MP3s. This connectivity technology offers a more reliable connection with no drops while listening to high-quality online videos. You can watch your favorite movies on the web or play online games with your teammates without concerns of higher latency. Additionally, you can pair each bud separately with your device with the individual pairing feature.
