The so-called TWS comes from the acronym True Wireless Stereo, which stands for True Wireless Stereo, hence the name. True wireless earphones connect to devices that support Bluetooth, such as mobile phones, tablets, speakers or computers through Bluetooth. The left and right earphones are entirely separated, no matter between the left and right earphones or earphones to other devices are no longer any headphone cable. As a result, genuinely wireless headphones can be made very small, easy to carry a band to use; in recent years has been rapid development, has been the current market mainstream choice. As a headphone lover, I have experienced 19 types of TWS headphones since the rise of TWS. We're here to share with you the new Liberty Air 2 Pro noise-cancelling wireless headphones that we bought in early February. It is referred to below by its Chinese nickname, "Broad Noise Reduction Cabin", for ease of reading.
As usual, I'll give my actual review in terms of look, feel, Bluetooth connection, sound quality, noise reduction, battery life and charging, with some comparisons to other headphones (especially the previous generation Liberty 2 Pro).
The packaging is the same as Liberty 2Pro's, with a poster and logo on the front and a list of features and accessories on the back. The side features PureNote technology and recommendations from Grammy-winning musicians.
Still familiar with the magnetic suction clamshell design, the back of the box cover details the unique five active noise reduction modes of this noise reduction cabin, which is also the most attractive place for me.
Lifting the transparent plastic protective cover, take out the noise reduction cabin's earphone and charging case. The design of separating the earphone and charging point is still the same here. I think it might be better to put the earphone in the charging case.
Charging cables, instructions, and accessory cards are arranged precisely as the Liberty 2 Pro, in a familiar fashion.
There are still eight groups of silica gel earcaps of different sizes, plus the group preinstalled on the earphone, a total of nine groups. To make users comfortable to wear, Kuo has been meticulous in considering the details of earcaps.
My case is agate black. The charging case's shape is more rounded than that of the previous Liberty 2 Pro, with the same logo on the front and a small bump on the bottom for the push-pull cover. This bump is more pronounced than the bump on the Liberty 2 Pro case, giving it a better push-pull feel.
On the back of the charging case are a USB-C charging interface and multi-function buttons. This time, the charging interface has abandoned the previous generation's protective cover, but it's not a problem.
Charging box push-pull slide cover design seems to be only sound rich, so do? But to tell you the truth, I like this design very much, one-handed opening and closing effortlessly. In the hands of a lot of flip design charging boxes in the opening and closing can not be so convenient; a few even one-handed opening and closing are tough.
Compared with the previous generation, the noise reduction cabin headset's shape has also changed a lot. The earphone handle is added, and the physical keys are removed to change to touch control. I am satisfied with this change.
Compared with the previous Liberty 2 Pro, the wide noise reduction cabin's design has changed a lot, and the personal feeling of wearing the house has been significantly improved. For a long time (more than 1 hour at a time), there is almost no discomfort in the ear, while the previous Liberty 2 Pro experienced slight pain. And wear the fastness is also very good, personal measurement wearing it running for half an hour, very stable, no sliding.
It's worth mentioning that the Soundcore app includes an "earplug test" to check the tightness of the earplugs, which can help select the proper headgear.
For actual wireless earphones, I think the speed and stability of the Bluetooth connection are critical. The Bluetooth connection speed of the noise reduction cabin is good. Generally, it can be connected after taking it out of the charging case and putting it into the ear, reasonably satisfactory.
I was also interested because the Noise-Removing Cabin comes with an updated version of Heard 2.0 and PureNote sound screening technology from its critically acclaimed predecessor, Heard, which continues the Grammy sound of its predecessor.
Let's start with Heard 2.0's voiceprint self-tuning feature, which tests the user's sensitivity to sounds of different frequencies and then compensates with AI sound to provide a more personalized sound quality experience. I think it's a great idea. Heard 2.0 has a more reasonable detection process than its predecessor, so the detection performance is also improved.
