Biggest selling points are long battery life (9.5 hours per charge), comfortable semi-in-ear fit, and decent sound quality, thanks to some in-app EQ customizations. Me wearing TOZO Tonal Fits T21. On the other hand, they suffer from typical classic earbuds (without ear tips) problems, like weak passive noise isolation and sub-bass extension in the music, as well as loose stability when exercising. This review will explore whether the pros outweigh the cons and who these earbuds are best for. Pros & Cons: Smooth, full default sound tuning Long battery life of 9.5 hours per charge Cheap yet well-built with an IPX8 rating TOZO app keeps getting new features Superb comfort thanks to the semi-in-ear design… … but poor in-ear stability due to that design Weak passive isolation that boosts ambient noise Undetailed, untextured audio performance Why Trust Us? We’ve tested over 200 headphones and written equally as many in-depth articles on audio. We take our testing seriously so that you can learn everything about the headphones you’re buying. Here’s a precise description of how we test headphones. CONTENTS (show more) Our Analysis and Test Results From our in-depth testing, TOZO Tonal Fits T21 offer an unbalanced default sound with dominant bass and lower midrange region. Earbuds also showed weak passive noise isolation results during noise measuring tests. In contrast, they almost reached the promised 10 hours of battery in our battery life test, in which we got 9 hours and 27 minutes. Sound 3.0 Good TOZO Tonal Fits T21 deliver a surprisingly full sound, despite their non-in-ear fit, and provide an accurate imaging. However, they’re highly undetailed and lacking airiness. Key points: Slightly dull default sound with a punchy bass and undetailed treble. Relatively natural sound once applying our custom EQ settings. While the soundstage is small, the imaging is pretty accurate. Check our TOZO Tonal Fits T21 A/B sound test TOZO Tonal Fits Sound Quality Test – HeadphonesAddict Gone are the days when classic earbuds couldn’t output bass. Apple AirPods 3 showed they can be bassy, whereas SoundPEATS Air3 Deluxe HS proved they can be very balanced. Well, TOZO Tonal Fits T21 demonstrate that they can deliver a full, punchy sound even for less than $30. However, unlike those two options, the TOZOs lack in technical performance, especially in the treble. EQing helps, but the sound congestion doesn’t go away. TOZO Tonal Fits T21 frequency response Due to poor fit, our measuring rig couldn’t accurately capture bass frequencies. Learn how to read our audio charts. Bass: Pleasant tone but lacks extension As mentioned, the bass (and lower midrange) are quite present on these earbuds, making the sound quite full. Maybe even too full. Fortunately, it doesn’t feel bloated, even by default. Low frequencies produce a pleasant rumble and are great for listening to acoustic songs, like “Mexican Girl” from Smokie. You also get to hear a decent bass kick. However, as expected, you don’t get much sub-bass rumble due to poor bass extension. Control is also lacking, especially when listening to rock or metal music. Listen to our custom EQ and other EQ presets TOZO Tonal Fits Custom EQ Comparison – HeadphonesAddict Midrange: Somewhat thin and untextured The midrange desperately needs some custom EQing, as it sounds thin and muted by default. Making a few EQ tweaks helps make the sound more natural, but they don’t fully resolve the thinness. Vocals benefit the most from the EQ tuning, while the instruments remain relatively untextured and dull. At least electric guitars get slightly more energetic. Treble: Smooth but undetailed Treble is overall pleasant, which is uncommon for TOZO earbuds (they typically display obvious V-shaped sound signature). It produces a pleasant sizzle but gets easily lost in the mix. You should boost the treble slightly to give it some energy and presence. However, don’t expect to hear more details than before. TOZO Tonal Fits T21 and T20 (right) are, design-wide, almost identical. Soundstage and imaging The soundstage is relatively small and only big enough to prevent the sensation of sounds playing inside your head. In contrast, the imaging is surprisingly accurate. You can easily track the sound’s location when you hear it panning from left to right. Sound Comparison My conclusion TOZO Tonal Fits T21 offer inoffensive sound tuning that desperately need some EQ tweaks. After doing so, they sound good enough for most people, especially those who really dislike in-ear fit. On the flip side, if the in-ear fit doesn’t bother you and you want a better sound, you should definitely check the TOZO T10 (2024 Version). Also check other: Best cheap earbuds Comfort & Fit 3.0 Good TOZO Tonal Fits T21 provide exceptional comfort thanks to their design. However, because of it, they also fall out of your ears after just a gentle head swing. Earbuds have a semi-in-ear design, which means they avoid using ear tips. That results in zero ear canal pressure or scratching. Due to their similarity with earbuds like Apple AirPods 3, they’re also incredibly comfy. You don’t feel them at all during usage, even during longer listening sessions. However, this design is highly impractical for stability. Unlike AirPods 3, the Tonal Fits use matte instead of glossy plastic. The latter touches your skin with more surface area, which improves overall stability. Glossier plastic seems to better hold to your skin than matte one. In comparison, you can feel the Tonal Fits sliding and twisting in your ears after just the slightest movement. I leaned my head slightly backward, and the earbuds immediately fell out. Consequently, I don’t recommend these for exercising or outdoor use since you might lose them. That said, some ears are more compatible with semi-in-ear design than mine, so your experience might differ. How pocketable is the charging case? The charging case is relatively small but not as small as the Apple AirPods 3 or SoundPEATS Air3 Deluxe HS. While not as tall as the other two, it’s noticeably “fatter”, which results in a more noticeable bulk in your pocket. Charging case is identical to the TOZO T20 model. Comfort and fit during activities: Commuting: Their exceptional comfort makes them ideal for commuting or traveling, while their inadequate stability might be a problem when exiting public transport or walking down the street. Exercising: Earbuds lack the stable fit needed for exercising. Suitable for weightlifting at best. Running: Weak fit causes earbuds to jump in your ears, meaning you need to constantly readjust them instead of focusing on running. Compared to other similar models TOZO Tonal Fits T21 are as comfy as most classic earbuds, like the Air3 Deluxe, or even more comfortable than the JBL Tune 225TWS, but they are less stable than AirPods 3. Durability 4.5 Almost Perfect TOZO Tonal Fits T21 have an IPX8 rating, meaning they can survive full water submersion for over 30 minutes. In contrast, the charging case is unprotected and has a fragile-looking hinge. Housing materialPlastic, matte finishEartip materialSiliconeOfficial water resistanceIPX8Official dust resistanceNone Like the TOZO T10 (2024 model), the Tonal Fits boast an IPX8 rating, meaning they can withstand sweating and even swimming underwater at 1.5m depth for longer than 30 minutes. Conversely, earbuds do not have a dust rating, so you should still avoid using them in dusty places (outdoor roads and workout areas). Earbuds look shiny from in-ear greasy after first use, so make sure to clean them regularly. How do they feel in my hands Earbuds sport a basic TOZO design and feel lightweight. They’re made of 6 pieces, which is a bit much, but they seem tightly glued together. Despite their stem design, it doesn’t seem like they could accidentally break open. Charging case durability Unfortunately, the charging case doesn’t have the same protection as earbuds, so you should keep it away from moisture and dust. Moreover, the lid’s hinge is thin and is probably the first thing to break if the case falls on the floor. Are they suitable for… Wearing in the rain: Earbuds will easily survive wearing them in light and heavy rain. Running & exercising outside: They’re durable enough for exercise, although their lack of official dust resistance means you should be cautious not to wear them on overly dusty roads. Sweating: You can peacefully drench them in sweat and later wash them under a tap. Dipping underwater: The Tonal Fits’ IPX8 rating means you can even use them for swimming (although we don’t recommend it). Wearing in light rainSuitableWearing in heavy rainSuitableExercisingSuitableSweatingSuitableDipping underwaterSuitable The only difference between Tonal Fits and T20 is that the latter use ear tips. Durability comparison TOZO Tonal Fits T21 are similarly durable as TOZO T10 and TOZO T20 (both rocking IPX8) and more durable than SoundPEATS Clear (IPX4). Battery 5.0 Perfect TOZO Tonal Fits T21 play music for 9 hours and 27 minutes on a single charge, with another 34 hours packed inside the charging case. They also support Qi wireless charging, but there is no official mention of fast charging. Tested battery life9 hours 27 minutesOfficial battery life10 hoursDifference33min (-5.5%)Quick chargingn/aQi wireless chargingYes TOZO Tonal Fits T21 battery comparison Tonal Fits are yet another TOZO earbuds (without ANC) that dominate the battery duration charts. In our battery life test, where we left them playing at 50% volume, we got precisely: 9 hours and 27 minutes of playtime on a single charge, with another 34 hours left in the charging case. That’s only 30 minutes less than in TOZO T20 and an hour less than in TOZO T10 (2024 Edition). That said, they are far from the SoundPEATS Sonic with their 14-hour battery life. Nonetheless, the charging case holds another 34 hours of playtime and supports Qi wireless charging, which is neat for less than $30. Strangely, though, there’s no mention of the fast-charging support. TOZO Tonal Fits T21 case has an LED screen that shows the battery percentage of the case and the remaining battery in each earbud. Battery rating comparison Here’s how Tonal Fits battery rating compares to ratings of similarly priced competitors: Note: The battery rating considers battery life compared to alternatives, wireless charging support, and the speed of recharging. Features 4.0 Great TOZO Tonal Fits T21 are cheap yet feature-rich, with good call quality and many customization options in the app. You can even join a community of TOZO users and select EQ presets from those exact users. TOZO is getting really generous with their products, even the ones that cost less than $30. Generosity comes in the form of their app, which is continuously receiving new features. First page in the TOZO app. App allows you to: Change controls Tweak EQ settings Engage with other TOZO users Update firmware Of course, some features require you to create an online account. However, you don’t need to do that to access the most important ones (unlike SoundPEATS, which forces you to register even to use the app). Control customizer Customizer lets you allocate commands to a different gesture. You can use single, double, or triple taps and long-press gestures. The only limitation you get is that long presses only work as volume controls. Fortunately, you can turn off gestures you don’t need or cause problems (like “ghost touches” when your warm breath activates the single tap command). Touch control customizer in the app. Sound Effects TOZO continues to provide its 10-band graphic audio equalizer, which often greatly improves the sound. Tonal Fits are no different. Feel free to use our custom EQ settings to improve your sound. Apart from 16 EQ presets, the “EQ Zone” is the new feature where you access custom EQ settings posted by the community. Of course, you need to register to access it. EQ Zone (left) offers you custom tunings from other TOZO users. You can also submit your own EQs to the “zone”. Community (social network) Recently, TOZO created a “Community” where users can post images and engage with other users. It’s similar to Instagram and less laggy than at launch (although still quite laggy). I don’t see this feature’s appeal, primarily due to random headphone posts that people share (I mean, what else could you expect from TOZO’s social media). It doesn’t lure you to spend multiple hours on it, like other social media apps. “Community” social media is filled with images of headphones, cats, and flowers. “Explore” tab Tapping the Explore tab gives you access to numerous “soothing sounds” that help you relax after a stressful day, focus on your work, or fall asleep. Open the playback interface to set the audio clips them to play in a loop. Furthermore, note that some clips refuse to play, which is strange. Feature offers good quality audio clips, but make sure to set them in a “loop”. Otherwise, it’ll shuffle between different clips, which might disrupt your relaxation. Microphone quality TOZO Tonal Fits T21 provide a satisfactory call quality thanks to their dual-mic noise canceling tech, especially when speaking in quieter environments, with some distortion once exposed to louder noise. TOZO Tonal Fits T21 microphone test: (no noise test from 0:00-0:22, with background noise test from O:22-0:46) Tonal Fits actually perform better than other TOZO earbuds under $50, delivering overall good call quality. Your voice is a bit too full (lower frequencies are slightly too boosted), but you remain perfectly understandable. When exposed to loud traffic, your voice gets slightly distorted and less clear. However, you still sound better than most competitors under $50 and especially under $30. If you’re looking for affordable earbuds with decent microphones for quick phone or video calls, TOZO Tonal Fits are a good choice. Features rating comparison For the price, these have a ton of features, which puts them in a high spot compared to most competitors. Noise Isolation 1.5 Meh TOZO Tonal Fits T21 have poor passive noise isolation and actually boost some midrange frequencies due to their design. They also leak sound out, although less so than you might expect. Measured average noise isolation3,79 dBA Passive noise isolation performance of the TOZO Tonal Fits is some of the weakest on the market. It closely compares to the SoundPEATS Air4, another semi-in-ear earbuds. That noise increase isn’t an error; you can actually hear more ambient noise shimmer when wearing these earbuds. While you can expect poor isolation due to their design, they also boost outside noise. Midrange frequencies, in particular (between 1kHz and 3kHz), to which our ears are the most sensitive. Consequently, when walking down a busy road, tire noise is noticeably louder and more shimmery than when you don’t wear earbuds. That makes them unsuitable for outdoor use and commuting. Here’s a table of how effective is TOZO Tonal Fits T21’s passive noise isolation at blocking specific frequencies: FrequencyNoise reductiondB SPLNoise reductiondBA (A-weighted)100 Hz0 dB-19,1 dBA200 Hz0 dB-10,8 dBA400 Hz0 dB-4,8 dBA600 Hz0,3 dB-1,9 dBA1 kHz1,1 dB+1,1 dBA2 kHz4,5 dB+5,7 dBA4 kHz16,6 dB17,6 dBA6 kHz8,8 dB8,9 dBA10 kHz7,1 dB4.,6 dBA15 kHz4,4 dB-1,6 dBAAverage/3,79 dBAA-weighted values from the International standard IEC 61672:2003 How severe is sound leakage? Sound leakage is noticeable, so you shouldn’t wear them in quieter public spaces like libraries. At around 60% volume, people around you could perfectly hear what you’re listening to. Noise isolation rating comparison with other models Bluetooth 3.5 Almost Great TOZO Tonal Fits T21 can reach an indoor Bluetooth range of 45 feet (13.7 meters) and sport a robust Bluetooth version 5.3. However, they lack multipoint connectivity and have a visible in-game audio lag. Bluetooth version5.3Bluetooth range(no obstructions)200ft+ (60.9m+)Bluetooth rangethrough a wall45ft (13.7m)MultipointNoAudio latency(audio delay)140ms With Bluetooth 5.3, Tonal Fits shouldn’t have connection issues in a building full of other wireless devices. At least, that was the case in my experience. Even when leaving a transmitting device (smartphone) on the other side of the house, I haven’t encountered any interruptions or stutters. Earbuds managed to reach: 45 feet (or 13.7 meters) of indoor range, or a few feet more after passing the second brick wall. Unfortunately, while having strong connection, they lack Bluetooth multipoint. That’s not a dealbreaker but still a neat feature to have. TOZO Tonal Fits T21 connection is as reliable as any modern true wireless earbuds with at least Bluetooth version 5.2. How to pair TOZO Tonal Fits T21? To pair these earbuds, you simply need to take them from their charging case and wait for the pairing mode to initiate automatically. Learn more detailed steps on how to pair TOZO earbuds to any device you want and troubleshoot pairing issues. To pair them to a different device, follow the instructions above but ensure to turn OFF Bluetooth on devices that were previously connected to the earbuds. What Bluetooth codecs do they use? TOZO Tonal Fits T21 sport basic SBC, AAC, and the new LC3 audio codecs, the latter being part of Bluetooth 5.2 and above. Is there an audio lag? There’s no visible audio lag when watching video content on YouTube or social media apps like Instagram or Facebook. Video latencyNot visibleGame latency140ms On the other hand, there’s a noticeable delay when playing mobile games. Since there’s no Game Mode or a Bluetooth codec to minimize latency, competitive gamers should avoid these earbuds. Bluetooth rating comparison Should You Get TOZO Tonal Fits? 3.5 Almost Great TOZO Tonal Fits T21 wireless earbuds have ups and downs, but generally, they’re hard to recommend unless you really dislike in-ear fit. But even if that’s the case, you should look at some alternatives instead. Pros & Cons Smooth, full default sound tuning Long battery life of 9.5 hours per charge Cheap yet well-built with an IPX8 rating TOZO app keeps getting new features Superb comfort thanks to the semi-in-ear design… … but poor in-ear stability due to that design Weak passive isolation that boosts ambient noise Undetailed, untextured audio performance Tonal Fits’ major problem is their poor stability and noise isolation. Who are these best for… They’re only suitable for users who will use them at home. For users that find in-ear fit uncomfortable or too isolating. For users who conform to the two statements above and don’t wish to spend more than $30 on TWS earbuds. Who should avoid them? Active users should avoid these earbuds due to poor stability. Users who plan to use earbuds outdoors or for commuting should also avoid these earbuds. How do TOZO Tonal Fits compare to the competition? They have an above-average battery life of 9.5 hours on a single charge. TOZO apps offers many features, including community EQ settings, which competitive apps don’t provide. Earbuds offer fantastic comfort compared to other in-ear competitors. In contrast, they aren’t nearly as stable as competitors, even some semi-in-ear ones. Their sound quality is highly undetailed. Here’s their value rating compared to similar alternatives: Are they worth the price? As of the time of writing, the TOZO Tonal Fits T21 cost precisely $28.79 on Amazon, and a coupon can further reduce their price. If you’re searching for non-in-ear earbuds, this is a tempting offer worth checking. Just know that there are better in-ear options in this price range.
