Appearance Design & Comfortable Fit
The charging case is designed in a pebble-like shape, and the whole body is made of black matte material. There is a status light on the front of the charging case. There is a UBC-C charging port on the back.
TOZO OpenBuds earbuds adopt an ear-hook design with a matte texture as a whole – it can be divided into two parts, the sound chamber and the earhook. Among them, the earhook is made of soft and bendable memory material, which is comfortable to the touch. The chamber is a tough, low-key design style.
There is a pickup microphone hole for noise canceling on the outside of the chamber, and a status light is hidden in the microphone grid.
While adopting an open design, TOZO OpenBuds has also innovated in wearing – the dual-axis adjustment design has been introduced in the earhook to further improve wearing comfort.
With the help of the dual-axis adjustment structure, users can adjust the horizontal angle and vertical opening and closing angle between the root position of the earhook and the chamber. Among them, the horizontal adjustment angle can about 60°, and the vertical angle can reach 90° – allowing the earhook and the auricle to have a better fit.
After the actual test, it was found that even after wearing it continuously for 8 hours on a working day, there is no obvious squeeze or pressure on the ear, which can meet the needs of all-day wear.
Moreover, the dual-axis adjustment structure is not only conducive to wearing comfort, but also brings a “Buff” in sound quality – the 60° horizontal angle adjustment can also make the speaker hole closer to the ear canal, bringing a better hearing.
The adjustable earhook structure does not make the earbuds loose, but fits the curve of the ear better. Therefore, even if you wear it for strenuous exercise such as running and basketball, you don’t need to worry about the earbuds being fall off.
Connection & App Support
Open the lid and wait for the indicator light on the earbuds to light up to enter pairing mode. At this point, select “TOZO OpenBuds” in the bluetooth device list of your phone to connect quickly. When using it again, open the charging case to connect the successfully paired bluetooth device.
Also, TOZO OpenBuds support multi-point connection, which can connect two bluetooth devices at the same time. The OpenBuds use Bluetooth 5.3 technology for stable wireless connection and audio transmission. For example, first pair the earbuds with the mobile phone, and then let the earbuds re-enter the pairing mode to connect to the tablet/computer/smart TV, so that multi-device connection can be realized. Seamlessly switch the audio source of the earbuds on two devices – listen to music, watch videos, answer calls and switch at will.
TOZO OpenBuds support the TOZO App for Android and iOS. Just install and open the App on your phone, select “Add Device” to unlock more functions of the earbuds in the App.
The functions provided by TOZO App are very rich. However, OpenBuds has very few functions that can be set, only preset EQ, touch control and OTA upgrade.
In addition, what is more surprising is that there are many audios such as white noise and soothing music on the “Explore” page, which are convenient for listening to during daily wear. This function is supported when using TOZO Golden X1 and TOZO Crystal Buds – it should be a common function of TOZO headphones.
Controls & Battery Life
The touch area is on the logo area of the earbud, which can be controlled by single-tap, double-tap, triple-tap and long-press. Can control play/pause music, volume adjustment, answer/end call, previous/next track, activate voice assistant. And through the TOZO App, you can also set the control method of the left and right earbuds.
The battery capacity of the charging case is 650mAh, and the earbud is 70mAh. The single battery life is up to 12 hours, and the total battery life is up to 42 hours. Total battery life is 16 hours less than the Oladance OWS Pro, but they are very expensive – 229 dollars.
Sound Description & Sound Leakage
Thanks to the blessing of 14.2mm dynamic driver and TOZO ORIGX 2.0 sound technology, the overall hearing of TOZO OpenBuds is still excellent. The mid-high frequency has a certain of clarity, and the low-frequency also maintains sufficient strength and thickness. It can be said that it effectively overcomes the common shortcomings of open-ear headphones.
Take “Hotel California” as an example: The guitar sound is full, the drum sound is precise, and the vocals and instruments are layered. In other songs, the vocals are bright and clear, the mouth shapes are accurate, and the reproduction is high.
Of course, limited by the shape, open-ear headphones cannot compare with in-ear earbuds in terms of low-frequency quantity. However, the preset EQ is provided in the TOZO App, and the “BASS+” can be selected to enhance the bass.
Also, turn on the volume at 85% in a quiet scene, and there will be slight sound leakage within 0.5 meters. However, in noisy scenes such as outdoors and commuting, there will be no perceivable sound leakage.
Since the earbuds do not block ambient sound, TOZO OpenBuds are also very practical in office, meeting and other scenarios, because they will not affect communication with colleagues when worn.
Finally, TOZO OpenBuds also has the DSP call noise cancellation function. I conducted call tests outdoors, in the subway, and in shopping malls – even in the noisy environment, the vocal in the earbuds is still relatively clear – it will not be affected by the sound of motors and engines.
Conclusion
The TOZO OpenBuds have a good sounding and touch control. The comfortable of open-ear headphones is further improved through the new earhook structure. Whether it is commuting, sports, or in various scenarios such as workouts – OpenBuds have a very good performance.
