After nearly two years, Apple AirPods 3 was finally officially released on October 19th. Compared with the second generation, the audio experience has been fully upgraded. The Chinese professional audio equipment brand Soundcore also experienced two years of precipitation, launching an upgraded version of Liberty 2 Pro earbuds——Soundcore Liberty 3 Pro coaxial dual driver noise reduction headphones. Upgraded ACAA 2.0 coaxial dual driver technology, focusing on high-quality audio experience.
Soundcore Liberty 2 pro was released in October 2019. With a unique sliding cover design, the original invention patented coaxial dual driver acoustic system architecture ACAA 1.0. Has won a number of international design awards, and was recommended by 10 Grammy tuning masters.
Soundcore Liberty 3 Pro continues the classic design of the previous generation Liberty 2 Pro in appearance, and the overall texture and wearing comfort have been further improved. Functionally, it is upgraded to ACAA 2.0 coaxial dual driver technology, HearID ANC personalized human ear adaptive active noise reduction, with Fusion Comfort super comfortable wearing experience, and new 3D surround sound effects, support for dual device connection and other functions.
Upgrade the patented ACAA 2.0 coaxial dual driver acoustic architecture to provide the best sound quality and telepresence experience
In terms of audio performance, Soundcore Liberty 3 Pro has multiple technical applications of Soundcore. The first thing to mention, of course, is the patented ACAA 2.0 coaxial dual driver acoustic architecture, which is a strong iterative upgrade.
The acoustic architecture of the coaxial dual driver has two major advantages over the traditional sound unit. The integrated combination of dynamic bass and treble armature driver combines the advantages of dynamic mid-low frequency and armature high frequency, taking into account the three-frequency sound quality, providing powerful bass and Rich treble details. The treble and bass sounding unit and the sound outlet are on the same central axis, which minimizes the phase variation in sound propagation, can better restore the sound field information, and the musical presence is also stronger.
In layman’s terms, the phase of the non-coaxial placement structure is distorted due to reflection during the sound propagation process, which will produce the same effect as the collision of two water ripples and cause coloration.
Soundcore Liberty 3 Pro coaxial dual driver unit solves this problem very well. Through the tweeter directly facing the sound outlet, reflection and coloration are avoided, and the phase information is highly restored. The bass dynamic unit sound waves flow smoothly along the sidewall of the small gold cavity with a streamlined design, which can also minimize phase distortion and coloration. Minimizing the phase variation also makes it easier to capture the sound position and achieve a more immersive audio experience.
This iteratively upgraded ACAA 2.0 coaxial dual driver uses a 10.6mm large-size composite material diaphragm with a high-resolution armature driver customized by Knowles. It can provide surging, powerful and full low-frequency effects and more malleable and hierarchical high-frequency sound quality.
Soundcore Liberty 3 Pro also supports LDAC audio decoding technology, the bluetooth transmission data is 3 times higher than that of the SBC, and the sound quality has obtained the Hi-Res Audio Wireless high-definition audio certification. The upgraded Soundcore Liberty 3 Pro is recommended by 20 Grammy music producers.
The excellent acoustic configuration brings the ultimate music experience. 52audio used Soundcore Liberty 3 Pro to experience multiple lossless audio with different styles.
When experiencing 《被遗忘的时光》, Soundcore Liberty 3 Pro perfectly showed Tsai Chin’s unique mezzo soprano timbre. The opening vocals sang “是谁，在敲打我窗”, the sound is full and mellow, and the vibrato transition is clear and clear. Musical instruments enter the field, and the hybrid driver crossover processing presents a rich layer of audio details.
“ONE I LOVE” is a sung unaccompanied music, lacking the cooperation of the instrument, and the performance requirements for the sound details are higher. Soundcore Liberty 3 Pro can perfectly express Meav’s pure voice and feel the emotional changes in the music. The high resolution brought by the hybrid driver makes the treble clear and loud, the climax chorus heavy bass male voice is thick and lingering, the treble female voice is ethereal, and the three sounds of Meav sung unaccompanied blend together, and the details are very rich.
In addition, Soundcore Liberty 3 Pro also supports dozens of preset music types such as Soundcore Classic, Bass Boost, Classic, Hip Hop, Jazz, Pop, Rock, etc. to be integrated into the HearID curve, presenting different music styles for users to choose.
Soundcore Liberty 3 Pro also added the Soundcore 3D surround sound effect this time. Based on the Soundcore 3D surround sound algorithm, it processes sound data in real time, expands the sound field, and renders different components in the sound. After turning it on, you can clearly feel the changes in the sound field. The sound moves from the center of the head to the ears, and the hearing is more comfortable. The dense bass drums no longer have a brainstorming feeling. In addition to watching videos and playing games, it brings a more realistic and immersive audio experience.
Customized noise reduction, seamless switching of multiple scenes, the most comfortable noise reduction effect
Another major upgrade of Soundcore Liberty 3 Pro is the addition of HearID ANC personalized human ear adaptive noise reduction function, which supports high, medium and low gears to meet the noise reduction needs in different scenarios.
52audio continues to track the market and learned that the noise reduction function of TWS headphones has been rapidly popularized in the past two years, but in the current noise reduction headset market, most products only support a “one size fits all” noise reduction solution. However, due to different factors such as the wearing scene and the structure of each person’s ear canal, a single noise reduction solution cannot achieve the best noise reduction effect, which causes some people to experience discomfort when wearing noise reduction headphones.
Soundcore Liberty 3 Pro HearID ANC’s personalized adaptive noise reduction function combines two mainstream solutions currently on the market to ensure the most comfortable wearing noise reduction experience. On the one hand, in the “Soundcore APP”, based on the personalized noise reduction algorithm, the ear structure of different users can be tested through the “HearID ANC Test”, and the most suitable personalized noise reduction curve can be obtained.
On the other hand, the headset can also perceive the surrounding environment noise in real time through the environment adaptive noise reduction algorithm. Automatically switch three different intensity noise reduction modes according to the noise level of the external environment, so as to better adapt to the use in different environments.
Automatically enter advanced noise reduction in noisy environments to provide the best noise reduction effect. In a relatively quiet environment, medium and low-level noise reduction modes will be used to reduce the amount of noise reduction, reduce the negative pressure caused by redundant noise reduction, and make the noise reduction experience more comfortable.
In addition to the adaptive mode, Soundcore Liberty 3 Pro also supports a manual mode, which can be customized to preset three modes according to common usage scenarios and personal needs.
In terms of overall user experience, whether in a relatively quiet office, on a commuter vehicle with relatively stable noise, or on a noisy street, the HearID ANC personalized adaptive noise reduction function of Soundcore Liberty 3 Pro gives a very good Comfortable noise reduction effect.
Noise-cancelling headphones provide users with a quiet audio experience, but at the same time, due to the principle of noise reduction, using the noise-cancelling function in scenes such as running, cycling, and windy weather will generate wind noise, which will affect the user experience. Soundcore Liberty 3 Pro also has excellent control in this respect, with wind and noise prevention turned on by default in the APP. When in use, 1-2 seconds after hearing wind noise, you can clearly feel that wind noise is suppressed, which greatly reduces the impact of wind noise on audio.
Transparent mode is currently a function that TWS noise-cancelling headphones will be used at the same time to communicate, obtain important site information, and use in complex traffic such as crossing intersections, improving the convenience of obtaining information and the safety of wearing headphones. Soundcore Liberty 3 Pro supports two transparent modes: full transparency and human voice, to cope with different usage scenarios.
Ergonomic design, Fusion Comfort technology to achieve ultra-comfortable wearing
In order to achieve the best audio experience and the most comfortable noise reduction effect, Soundcore Liberty 3 Pro has made many efforts. And the foundation of all this of course also requires the headset itself to provide a comfortable wearing effect.
Soundcore Liberty 3 Pro adopts Fusion Comfort ultra-comfortable wearing technology, ergonomic design, and further improves wearing comfort through multiple optimizations. Soundcore Liberty 3 Pro is equipped with four specifications of liquid silicone eartips and air earwings. The softer material brings more comfortable touch and adaptability. In terms of structure, the earphone adopts a diversion and pressure relief structure, and the air penetrates between the front and rear chambers to balance the air pressure in the ear canal and reduce the negative pressure when wearing.
Everyone’s ear canal situation is different, and the wearing effect is also different. Girls’ ears are relatively small, using the smallest size eartips and earwings. In terms of user experience, Soundcore Liberty 3 Pro has a very comfortable and stable overall wearing effect after choosing the most suitable eartips and earwings. In the long-term wearing experience when writing the evaluation, there was no obvious discomfort such as ear canal pain.
Cosmic aesthetics color matching, small golden cavity design fully demonstrates the technological paradigm
Soundcore Liberty 2 Pro has won the CMF Design Award and the iF Design Award successively after its release with its unique exterior design. Soundcore Liberty 3 Pro continues the design language of Liberty 2 Pro in the overall appearance, but the volume is more compact, and through the application of a variety of materials, the texture of the product is further improved.
The Soundcore Liberty 3 Pro charging case follows the Soundcore classic sliding hinge opening design, and the overall volume is relatively smaller. The shell surface uses a unique hydrophobic, oleophobic and anti-fouling coating, which is not easy to contaminate fingerprints. The shell is still equipped with 3 indicator lights, so that the user can more intuitively obtain the remaining battery information of the charging case, and charge it in time. At the same time, it supports wireless charging function, which is more convenient to use.
The sliding cover design of the charging case makes it very convenient to open and close the cover with one hand. The feeling of magnetic attraction and repulsion during the sliding process also makes it a decompression tool. The headset cockpit in the charging case is still a “large space” design, which is very convenient to pick and place. The headset is positioned by magnetism and grooves. A hidden atmosphere breathing light is added in the charging case to feedback the headset pairing status.
Soundcore Liberty 3 Pro earbuds is the biggest place to upgrade the texture this time, using a combination of metal + mirror material. The decorative sheet on the back of the earphone is of mirror glass texture, using a hot pressing film process, the mirror effect is more depth and three-dimensional.
The front cavity of the earphone is made of metal material. This midnigth black is matched with a pink gold color scheme, which makes the overall appearance more cool and full of technology.
Soundcore Liberty 3 Pro is equipped with four cosmic aesthetic colors: midnigth black, frost white, fog gray, and dusk purple. Each color has a different expression of personality and can be freely chosen according to personal preference.
