TWS wireless Bluetooth headset I have used almost more than 10 models, the use experience is really very convenient, there is no shackles of the wire, a charging box can be put in the pocket, where to go can be carried. And now most mobile phones have eliminated the headphone jack, so this wireless headphones have become mainstream. But most of the sound quality of these headphones is as dull as boiled water, and recently experienced the Liberty 3 Pro in zaker, which has a good sound performance, compared to the AirPods I usually use, there is an ear improvement. Let me tell you more about this headset.
Unbox
On the front of the headphone package is its rendering, we can get a rough idea of the appearance of this headphone, Liberty 3 Pro sound wide small gold cavity is a coaxial coil iron personalized noise reduction headphones. The Hi-Res small gold label in the upper right corner shows that the sound quality of this headset is extraordinary. Printed on the back of the box are some of the selling points of this headset, as well as a product list. Many people may not be familiar with the soundcore brand, which is actually one of the world's top 10 Professional High-end Audio Brands in China, with 25 million European, American and Japanese users.
The design of the headphone packaging box is very careful, using a magnetic flap design, which opens like a book. The "Little Gold Cavity" ACAA 2.0 coaxial coil iron architecture is introduced on the left, with ear caps and ear fins in the middle and headphones and charging cases on the right.
There is a pair of headphones, charging case, charging cable, 4 pairs of ear caps and ear wings in the box to meet our needs in different sizes.
Headset appearance
The Liberty 3 Pro's sonic small gold cavity charging case is flat, oval, a bit like a pebble. The surface of the charging case is skin-friendly scrub texture, which feels very good and does not stick fingerprints. It is printed with a pattern similar to a musical note, which is actually a wide-sounding logo. The headphones are available in four colors: Obsidian Black, Milky Way Gray, Magic White, and Nebula Purple, and I got Obsidian Black.
The back of the charging box has a Type-C charging port, which belongs to the mainstream charging interface now, and you can find a cable around to charge it. Next to it is the pairing button that resets and connects new devices.
Unlike the mainstream clamshell type, this charging case adopts a slide-type design scheme, its damping is moderate, the opening and closing are smooth, giving me a feeling of using a slider phone before. There are enough gaps on both sides of the charging box, the headphones are very convenient to take out, the magnetic force is also very strong, and it is very easy to put it back, and there is no need to change the angle repeatedly.
Liberty 3 Pro sound wide small gold cavity belongs to the in-ear bluetooth headphones, the size of the entire headset is relatively large, and the weight of one ear is 6g. However, it has an ergonomic design that makes contact with our ears through air ear wings and ear caps. The air ear wing is stuck in the pinna, so that the headphones are stable and do not fall, and the liquid silicone ear cap fits the ear canal and plays a closed physical noise reduction effect. The three metal contacts on the headset come into contact with the charging case to charge.
The outer veneer of the headset adopts the hot pressing film process, which looks very advanced after refraction of light. This is actually the touch area of the headset, support clicking, double-clicking, three-clicking, long press two seconds, a total of four operation methods, and can customize different functions in the sound and wide APP, and the touch is also very sensitive.
The reason why this headset is called the sound width of the small gold cavity, because its cavity is made of aluminum alloy material, the advantage is that it can reduce the resonance and resonance of the sound, the sound quality can maintain a cleaner bass, and maintain the resolution and clarity of the sound. The black and gold color scheme also makes the headphones look very advanced.
The workmanship of the Liberty 3 Pro sound wide small gold cavity is also quite good, there is no burr at the seam, and the gap in the charging box is also handled very well. In addition, the headset also supports IPX4 waterproofing, which can resist the erosion of sweat and rain.
Usage experience
Although the size of this headset is larger, it is more comfortable to wear than the average earbud headphones, because it adopts an air-relieved structure, front and rear dual-hole diversion, even if there are ear tips will not be stuffy ears. In addition, the addition of air ear wings makes the wearing of headphones quite stable, and how to shake will not fall off.
After matching the device, it will automatically connect as soon as the charging case lid is opened. There is an infrared sensor on the headset, which supports the function of in-ear monitoring, and the headset will be automatically paused when the headset is taken off, and the headset will be automatically renewed.
The sound width of the small gold cavity supports the active noise reduction function, a total of low, medium and high three gears, but also supports the adaptive noise reduction function, the headphones will automatically monitor the noise level of the surrounding environment, automatically match the noise reduction gear. Active noise cancellation filters out low-frequency noise in the environment and attenuates high-frequency noise, giving me a quiet listening environment.
Generally, after turning on noise reduction, the ears will have a negative pressure feeling, which is particularly uncomfortable. However, the ear pressure of this wide and small gold cavity is very small, because it can accurately match the noise reduction curve for each ear through the ear canal acoustic test and reduce the ear pressure caused by noise reduction.
The headset also supports the function of wind noise protection, which can be turned on in HearID ANC and ventilation mode, which can effectively suppress wind noise and is very useful for outdoors with relatively large winds. In addition, the transparency mode also distinguishes between full transparency and vocal mode, which is suitable for outdoor use and amplifies all surrounding sounds. Vocal mode is suitable for indoors, and there is no need to take off the headphones when talking to others, but the measured vocal mode has a greater noise floor.
Through the sound app, we can customize the functions of each touch action to meet our usage habits. Not only can the left and right ears be controlled separately, but also the touch action can be turned off, which can be seen that its customization range is very powerful.
The loud and small gold cavity supports Al call noise reduction, and it can also be clearly called in noisy environments. This function is implemented by three microphones, the in-ear microphone weakens wind noise, the call microphone recognizes the human voice, and the ambient noise reduction microphone is responsible for filtering the ambient noise.
The official claim of the sound and small gold cavity can reach 8 hours of battery life, and the use of the charging box can achieve a total of 32 hours of battery life, but active noise reduction and other functions will affect its endurance. Generally, it can be used for about 6 hours, and it is no problem to use it for more than twenty hours with the charging box, and it can basically be charged once a week. In addition, it also supports wireless charging and fast charging, which can be used for 3 hours in 15 minutes and full in 2 hours.
Headphones can connect two devices at the same time, I usually connect laptops and mobile phones at the same time, so that I can listen to songs and chase dramas while working. The audio output can be switched at any time, but the experience is definitely not as good as AirPods, and there will be a pause of about 2 seconds when switching.
Sound quality performance
The sound wide small gold cavity adopts the design combination of dynamic and moving iron, the 10.6mm large-size dynamic unit is responsible for the bass and midrange parts, and the high-resolution moving iron unit customized by Lou Shi is responsible for the treble part. In addition, the small gold cavity also adopts the industry's pioneering acoustic patent ACAA 2.0 coaxial coil iron architecture, which places the moving coil and the moving iron in the same axis, which is officially said to make the high and low tone transmission path consistent and have a broader sound field experience. The bass is surging and the treble is translucent, just like turning on the 360-degree audio-visual, and you are in the sound scene.
The small gold cavity is still one of the few headphones that support LDAC codec, and has been certified by Hi-Res to hear more sound details than the ordinary AAC protocol. However, it can only be used by connecting to an Android phone, and it will increase the power consumption, and it is worth it for better sound quality.
Recently, I have listened to it for a while with a wide sound and a small gold cavity, and the sound quality has indeed improved qualitatively compared to other Bluetooth headphones. Taking Cai Qin's "Ferry" as an example, thanks to the 10.6mm large-size dynamic unit of the headset, the low frequency sense is abundant, the drum depth is dived, and the speed is fast and powerful. The details of the middle and high frequencies are well preserved, the vocals are clear and infectious, and the high-frequency parts are clear and unbroken.
Listening to "Hotel California", the high-pitched part of the headphones is very transparent and has excellent transient performance. It has a vast soundstage, creating a sense of space, an immersive sense of presence, and can clearly distinguish the position of different instruments. The sound is wide and the small gold cavity has a strong analytical power, and it will not be harsh while hearing the details.
In the APP, there are powerful sound customization functions, such as HearID will test the hearing sensitivity at multiple frequencies, and then generate their own EQ. Professional built-in Grammy winners to create a boutique equalizer, if you are not satisfied with the built-in sound, you can also customize the EQ equalizer according to your preferences.
summary
Recently used for a while, the Liberty 3 Pro has a wide and small sound cavity, and overall it is a wireless Bluetooth headset with excellent sound quality and powerful customization features. The ACAA 2.0 coaxial coil iron architecture and LDAC codec mode give it outstanding sound performance. In the APP, you can realize the touch operation and sound effect of the headset, and make powerful customization settings to meet the personalized needs of different people. In addition, the adaptive noise reduction and comfortable wearing of the headphones bring me a good experience.
