In the past two years, TWS true wireless bluetooth earphones have emerged in endlessly. Various brands have successively launched thousands of bluetooth earphones ranging in price from tens of dollars to hundreds of dollars, but most of them have one feature: the sound technology of the earphones is not a single dynamic Technology is a single armature technology. There are few earphones that combine the two. In addition to the higher cost, the technical difficulty is also quite high.
I recently experienced a bluetooth earphones that uses coaxial dynamic armature technology——Soundcore Liberty 2 Pro.
| Part 1: Appearance Picture Tour
▼Soundcore Liberty 2 Pro charging case is different from AirPods in an oval shape. The black design and the white LOGO are not amazing, but they are of the kind that looks good. The surface is made of composite material, coupled with fine sandblasting treatment, it is very comfortable to touch, and it will not stain fingerprints.
▼On the side is the Type-C charging interface. Today, when the Type-C interface is popular, this interface is too convenient to use. You can find a data cable for charging, and it also supports wireless charging.
▼After talking for a long time, the charging case has not been opened yet. In fact, the charging case can be opened with one hand and the operation is very convenient. The best advantage of this design is to save space, and the earphones is not easy to lose. Moreover, the earphones can be used when it is taken out, and it can be charged after being put in. This is the first time I have encountered the sliding opening method. I always like to play it like this when I am fine. It is easy to operate.
▼Soundcore Liberty 2 Pro true wireless bluetooth earphones uses 3 contacts to charge in the earphones charging case. When the earphones is placed, it will automatically fit and adsorb and charge. It is marked with “L” and “R” beside it, so don’t worry about getting it wrong.
▼In terms of operation, the earphones does not use mainstream touch operations, but uses physical buttons. The biggest advantage of this design is to focus on sound quality. Different functions can be realized by clicking the buttons, and the operation is not complicated. Press the left/right button once to execute play/pause, press the right button twice to execute the next song, and press the left button twice to execute the previous song; during a call, press the right/left button once to answer/end the call, press and hold 1 The second right/left button will reject the incoming call; in the non-calling state, press and hold the right/left button for 1 second to activate the mobile voice assistant, of course, you can also activate Siri. The button feedback is quite good and will not cause ear discomfort.
▼The earphone uses the common mainstream deflection catheter in-ear type. Although the surface design is clear, the earphones are rounded around. During the in-ear wearing process, the ears will not be squeezed. This is because The ergonomic design is fully considered, which can satisfy most people’s wearing comfort, and it is not easy to fall after wearing.
| Part 2: Actual experience
▼As a true wireless bluetooth earphones, Soundcore Liberty 2 Pro has made great efforts in terms of sound quality. It uses 11nm dynamic+Knowles to customize the armature coaxial cavity design solution, which can resolve the richer high and low sounds while eliminating noise. The sound details are also shown vividly. These hardware guarantees that the Liberty 2 Pro true wireless earphones have a very good music experience.
▼The dynamic driver is a mid-low frequency sounding unit with high compliance and high radiation area; the armature driver is a high-frequency sounding unit with high elasticity and good transient characteristics. The advantage of dual unit integration lies in the clear division of treble and bass combination, which can have a wider bandwidth range; coaxial placement improves the reproduction of sound field information, which will give users an immersive experience when listening to music . TWS is used a lot, Soundcore Liberty 2 Pro is absolutely good.
▼ 《渡口》, there are three drums in front of this song, these three drums can test the low frequency extension of the earphones. The low frequency extension of the earphone is quite in place, which can restore the real tone well and has good penetration. 《偏偏喜欢你》, the soundtrack of this song uses strings and piano, which can be a good test of the performance of the earphones on the mid and high frequencies. The high frequency is not ear-piercing, and the intermediate frequency is fairly clear. When you listen to the Soundcore Liberty 2 Pro true wireless earphones, you will immediately lose AirPods. The reason is that Liberty 2 Pro has more detailed details, relatively balanced tri-band performance, and natural transition between high and low sounds, especially bass and treble.
▼The sound quality of the Soundcore Liberty 2 Pro true wireless bluetooth earphones is excellent. Another issue that everyone cares about is the latency of bluetooth. When playing PUBG Mobile, you can clearly feel that there is almost no delay. This is because the mainstream bluetooth 5.0 chip is used. Compared with the previous bluetooth 4.2, it has lower power consumption, faster pairing, and stronger compatibility. The signal transmission is also more stable. The biggest feeling is that when playing games, I can clearly feel that there is almost no delay.
▼As a true wireless bluetooth earphones, Soundcore Liberty 2 Pro can be used immediately while achieving a stable connection. After the bluetooth connection is matched for the first time, it will automatically connect to the bluetooth when it is taken out of the charging case. The speed is very fast and there is no sense of procrastination. In terms of operation, some friends may say that the touch is uncomfortable, this depends on personal preference. After using it for a period of time, I think the button feedback is still very good, and it is easy to change songs and arouse the voice assistant.
▼Although active noise reduction is not supported, passive noise reduction is still not bad. It provides beam forming directional field during voice calls, which can effectively suppress environmental noise and bring high-fidelity call quality. Even if it is used in noisy streets, subways and other environments, it can maintain clear call quality.
▼Let’s talk about battery life, the Soundcore Liberty 2 Pro true wireless bluetooth earphones has a single battery life of 8 hours, and a 500mAh charging case can bring a total of 32 hours of battery life. Listening to songs for 3-4 hours a day can take up to a week, which can fully meet daily needs.
| Part 3: Different APP experience
▼Different from most earphones, Soundcore Liberty 2 Pro true wireless bluetooth earphones are also equipped with an APP called Soundcore. In addition to adjusting earphones, you can also control many Soundcore brand products, such as speakers.
▼Here, users can customize the control buttons, which is more in line with everyone’s habits.
▼HearID is a good function that can test the user’s hearing sensitivity at different frequencies, and perform sound quality calibration based on the monitoring results, and customize personalized EQ for users.
▼For music enthusiasts, the addition of music equalizer function makes earphones more fun. The user can manually adjust the parameter part according to the song type or use scene, or directly select the preset function, which meets the needs of the user to adjust the sound effect to suit their own style.
