Tozo 12 Wireless Earbuds – A Promising Upgrade
If you disliked the lack of aesthetic appeal and no so good design of the Tozo T10 Dock and earbuds controllers, then it’s worth checking out the new upgrade from the brand. Though Tozo is still struggling a bit somehow, the brand is proceeding in the right direction with improved models.
Enthusiasts have started noticing Tozo because of its price vs. features ratio. Now I am going to evaluate the design, battery, connectivity, and sound quality of the Tozo T12:
The outlook of the Tozo T12 wireless earbuds is largely conventional. The primary material of T12 earbuds is matte plastic, which is good at resisting fingerprints.
The outer ring features a glossy accent. The T12 earbuds’ size is slightly larger, and the shape is rounder than that of the T10 earbuds.
Tozo T12 Earbud weighs 0.03 lbs. The comfort level is decent. Without tips, the T12 earbuds can slip deeper into the ear canal. However, the package comes with various ear tips for you to use the most suitable tip-size.
Earbud controls of T12 are touch-sensitive. That is what the Tozo T10 is missing and turned into a huge flaw since you had to press the controls so hard that they slipped deeper into the ear.
The plusher tips make the Tozo T12 earbuds less tiring. The touch-sensitive controls support music, calls, and volume. However, these buttons lack microphone control, channel mixing, talk through, and noise cancellation. And you get no additional controls with the Tozo T12 wireless earbuds.
The dimensions of the Tozo T12 earbuds are:
- Length: 1.5-inches
- Width: 1.1-inches
- Height: 0.8-inches
The volume of the earbud is 1.3 cubic inches.
The portability of the earbuds isn’t an issue with most of the brands; what counts is the size of the Dock or charging case. The Tozo T12 Charging Dock is comparatively taller than most of the truly wireless earbud docks.
Still, the dimensions of the Dock (3.0-inches x 1.5-inches x 1.4-inches) are convenient to carry around. The volume of this hard-charging case is 6.3 cubic inches.
The design is good, sturdy, clean, and overall it’s better than the Tozo T10’s charging case. The case is also water-resistant (IPX8).
The spring-loaded lid keeps the charging dock from opening inside the pocket. The USB-C charging interface is on the back of the dock. The package contains the Type-C charging cable.
Wireless charging is supported, and there is also a miniature interior display demonstrating the battery status of the dock and the buds.
The Tozo T12 comes with a rechargeable battery. The continuous battery life of Tozo T12 earbuds is 5.3 hours, and the dock offers 23.9 hours of reserve charge. The charging time is around 70 minutes.
The good news is that the Tozo T12 earbuds offer to charge without interrupting audio (Mono audio through an earbud while the second one is charging). However, it doesn’t support passive playback.
Tozo doesn’t improve in this regard. Just like Tozo T10, the Tozo T12 earbuds also come without a dedicated or companion app.
This model is an in-ear Bluetooth-only version, and the earbuds use Bluetooth 5.0 version. The model doesn’t support multi-device pairing and NFC pairing. The line-of-sight range is 183 feet.
The Tozo T12 earbuds are also compatible with PCs, but in this case, the audio latency is much higher, which is not good, especially for gaming.
These earbuds are not compatible with PS4 consoles.
The sound profile is a bit V-shaped and exciting while providing more of a low-end thump. The treble response is overly brighter with little sound piercing. The bass amount is 5.15 dB, whereas the treble amount is 0.75 dB. Tozo T12 earbuds sound more versatile with better mids where the lead instruments don’t get suppressed.
Frequency Response Consistency
The Average Standard Deviation is 0.06 dB. It is much better than most of the wireless earbuds. By selecting the right ear-tips and tighter seal, the listening experience is better than I expected from Tozo.
With Standard Error 5.55 dB, Low-Bass 8.33 dB, Mid-Bass 6.0 dB, High-Bass 4.22 dB, and 10 Hz Low-Frequency Extension, the Tozo T12 wireless earbuds don’t stand out in this regard. Bass accuracy is nothing but mediocre, though I was expecting something much better this time from Tozo. Some tracks, across the range, sound overemphasized with a distinct boom at times.
Unlike bass accuracy, the Mid Accuracy of Tozo T12 is excellent. 1.56 dB Standard Error, 0.61 dB Low-Bid, -2.13 dB Mid-Mid, and 0.0 dB High-Mid reflect above-average mid accuracy.
However, you may notice a slight dip at times in the Mid-Mid that makes instruments sounding from the back. Vocal in Mid Range is much clearer since there is no sign of harshness or clutters.
The treble accuracy of Tozo T12 earbuds is neither good nor bad. Standard Error is 4.12 dB, Mid-Treble 0.82 dB, Low-Treble 4.12 dB, and High-Treble 1.82dB are suggestive of an average treble performance. The low-treble response is overemphasized, and it makes the earbuds sound harsher than you’d like.
The noise isolation of the Tozo T12 wireless earbuds is above average. The overall Attenuation is -21.98 dB with -10.73 dB Bass and -19.38 dB Mid, whereas the Treble isolation is -36.54 dB. However, you may feel uncomfortable with low-pitch sounds such as the rumble of a plane, bus, or train at a distance.
Microphone / Sound Recording
The Tozo T12 wireless earbuds come with an integrated microphone. The recording quality is just OK, much similar to what you get from the Tozo T10 microphone.
The sound recording turns out to be far from natural. It is more muffled and thinner than your original voice. Also, the noise cancellation feature of the microphone is closer to mediocre.
In short, there is not much improvement in the microphone of the T12 as compared to its predecessor, the T10.
I don’t have mixed feelings while concluding this review because there are some major improvements, especially in this model’s design and charging dock.
For instance, the design, build, and battery playtime of the Tozo T10 were mediocre, and the idea of a mechanical controller was a major drawback. The design team seems to be more focused on the design features and controllers of Tozo T12, and, in my opinion, they have done much better job this time.
Despite some shortcomings of the T10, they have always been decent headphones at a competitive price. And now, the Tozo team just continues their success by making the T12 even more interesting than its predecessor.
