No, you can even measure your heart rate with earphones. Is this the era where earphones are taking over the functions of smartwatches? Hello, this is Balpumnam. Finally, the much-awaited sequel, Liberty 4, has been released. Liberty 3 Pro was introduced as the strongest cost-effective earphones in the 100,000 won range, leaving nothing to be desired. Even now, there aren't many products that can support such performance in this price range. However, there was one downside to Liberty 3 Pro, which was the design that divided opinions. Did the new Liberty 4 successfully address this flaw? Also, what new features does Liberty 4 have compared to its predecessor, Liberty 3 Pro? Once again, I will directly test the sound quality, overall quality, active noise cancelling, and more.

I will tell you about it. Let's start right away. [Music] Okay, let's proceed with the unboxing. [Music] Let's start by looking at the packaging. Anker has been paying quite a bit of attention to packaging since the previous model. Comparing it to the recently reviewed Galaxy Buds 2 Pro, you can definitely feel the difference. The components include the earphones, ear tips, a 2C cable, and a manual. Especially this time, four types of ear tips are supported. Moreover, unlike the previous earphones that all had regular ear tips, this time they come with Cloud Comfort ear tips. What is this? It was made with Anchor's exclusive technology, using a cloud-like soft material to create a dual structure. Therefore, it reduces ear pain while providing a very high level of adhesion. When I wore them, I felt good with the ear tips.

The physical shielding was much better than the previous model. Now, let's take a closer look at the case. The material of the case itself is similar to previous models, and compared to Liberty 3 Pro, the design is also similar. However, Liberty 4 comes in a more compact size, which improves portability. Overall, it is smoothly finished in matte, with some glossy accents. The Soundcore logo is embossed on the top of the case, and a USB-C port is provided on the back. Next, let's examine the hinge. Like the previous model, it is designed in a sliding style. While most are familiar with the top-opening style, the sliding design is quite convenient once you get used to it. When sliding Liberty 4, it feels smooth, and the locking after opening is also good. Next, let's take a look at the earphone unit.

While using Liberty 3 Pro, the only downside I thought was the design, but this time, the design seems to be less divisive. It's not incredibly innovative or beautiful, but it's made with a clean design that is unlikely to polarize opinions. Also, the weight of the earphone unit has been significantly reduced. The case is 55g, and the earphone unit is 5.8g, making it lighter compared to the previous model. Even though it is equipped with dual drivers, the successful miniaturization and weight reduction alone seem to be a significant outcome in terms of appearance in this new model. Regarding the appearance, the finish and build quality were good, and the design has become simpler and cleaner compared to the previous model. Next, let's look at the specs. Firstly, it supports Bluetooth 5.3, and in addition to the basic SBC codec, it also supports AAC.

I support the ELDEC. When used, the active noise canceling can be used for a maximum of 9 hours without the case, totaling 28 hours with the case. When ANC is turned on, it can be used for 7 to 24 hours, and when ELDEC is turned on, it can be used for 5 and a half to 16 and a half hours. Next, let's look at some convenient features. Charging is possible via a USB-C port, and it also supports wireless rapid charging. Moreover, it supports multi-point connections. Especially for those who, like me, use a smartphone and a laptop together, the multi-point feature is really useful. Typically, when enjoying music through a smartphone and working on a laptop, the sound automatically switches, which is a convenient feature. It can store up to 7 multi-point connections, and up to two simultaneous connections are possible. Now, a truly amazing feature has been added. Health monitoring features such as heart rate monitoring are built into the earphones.

The Liberty 4 has incorporated health features such as heart rate monitoring, stress check, posture alert, and exercise functions. Now, earphones can also utilize some functions of the smartwatch. The way is that the earphones are equipped with an optical heart rate sensor inside, which measures biological signals coming from the ear, not the typical wrist measurement method. To use it, you need to go into the app, activate Soundcore Wellness at the bottom, input your basic body information, and that's it. Here, not only simple but various exercise functions could be utilized. Especially, when wearing this and working on a computer, if your posture deviates, automatic alerts will sound, so there are quite a few useful functions. Next, we need to look at the most important aspect, sound quality. In this Liberty 4, three main technologies will be focused on.

But before I tell you about this, let's start with a conclusion about the sound quality. If we talk about the combination of the Eldec's here ID, you can consider it as the best sound quality in the price range of 100,000 to 200,000 won. Perhaps even compared to earphones in the 200,000 won range, it had such a sound quality that could compete. Now, let me explain more about the sound quality. First of all, the Eldec supported in Liberty 4 can deliver high-resolution, clear sound by transmitting a lot of data compared to AAC or SBC codecs. Also, this time, it is equipped with an improved ACA 3.0 driver technology compared to the previous model. This technology enhances sound distinction through two dynamic drivers responsible for high and low sounds, providing a splendid sound quality. Moreover, this time, it feels like the balance is better than the previous model. So, it is rich in high and low sounds, yet clean to listen to. Even in the previous Liberty 3 Pro.

The sound quality was really good, but if I had to point out one thing, it would be that in the high frequency range, there was a subtle distortion heard in the super high frequency range. Therefore, I mentioned that sensitive individuals may feel tired after listening to music for a long time. In this Liberty 4, the default tuning value also emphasizes the high frequency range. Personally, I enjoyed the sound of the high frequency range, so I was satisfied with using it without separate tuning. However, there may be people who want to reduce the high frequency range. For those people, the anchor also provided a solution. Now, mentioning whether the earphone's tuning value is good or bad doesn't hold much significance anymore. If you don't like the tuning value, you can simply set your desired value with the HER ID technology. So, what is HER ID technology? It allows you to set your favorite genre or comfortable frequency range for your ears for tuning.

It is a technology that sets values. From low to high range, you can set the tuning values you want. Also, you can apply the Her ID technology even in no-can situations, so it is a very useful function. Therefore, if you are considering purchasing a Liberty 4, I recommend investing about 10 minutes to use Her ID. Next, another interesting feature is the 360-degree immersive spatial audio system. Anchors support 3D sound that feels like listening to a live performance through an algorithm processed independently. Furthermore, gyro sensors are built into the earphones to detect movement, allowing for directional output. It really offers a wide range of features in the 100,000 won range, but you may not necessarily need to use the 360-degree system when just listening to music. It can feel rather cluttered. I recommend listening to music in normal mode. However, when watching movies or Netflix, this is when.

The feature was really useful. If you purchase this, I highly recommend trying the 3D sound test. It significantly enhances immersion. Moreover, for those who play games like VR or racing, it will make playing much more enjoyable. Next is the active noise canceling and ambient sound listening. Among the things that received the most praise in Liberty 3 Pro was the ANC. This time, the ANC feature in Liberty 4 was also excellent. This is also thanks to Anchor's proprietary technology, Noise Cancelling 2.0. It automatically adjusts the noise-canceling intensity according to the ambient noise level. Therefore, there is no need to manually adjust the ANC intensity every time you change locations. Especially, it even recognizes windy environments, suppressing wind noise when it suddenly blows. However, the limitations of this technology were also evident - noise.

It cannot catch changes in the environment very quickly, so it takes about 3 to 5 seconds to adjust the ANC intensity when moving from a quiet place to a noisy place. This part is expected to be improved later through hardware or software updates, which would likely increase satisfaction. Also, when the ANC intensity is set very high, the noise cancellation works better, but I felt a bit stuffy. So, if you are going to use the manual mode, I recommend setting it low for everyday use. I also tested the ambient sound listening feature, and I particularly liked the sound focused on vocals. There are two modes supported for ambient sound listening: full ambient sound listening mode and voice mode. Among them, I preferred the voice mode. Especially when using public transportation such as subways or buses, I liked using the voice mode.

When switching, the surrounding noise does not amplify significantly, and only the voice is heard clearly. So, the voice mode can be quite useful in everyday life. Now, let's listen to the call quality. First, I will listen myself and then discuss it with you. Hello? The voice you are hearing now is the call quality recorded with the Anchor Liberty 4 Pro in a quiet environment. How does my voice sound to you? Hello? The voice you are hearing now is the call quality recorded in a subway environment. How does my voice sound now? The call quality is still very good this time. In a quiet environment, the voice was clear, and even in a very noisy construction site environment, it was quite clear. For a more direct comparison, I also compared it with the Anchor A40 and Anchor Liberty 3 Pro. I will listen again and come back to you.

There's nothing to be disappointed about in terms of call quality. Now, after using the product for about 2-3 weeks, I will tell you the pros and cons I felt. First, the advantages. As expected, I felt that this anchor's new product was excellent. It was a product that was faithful to basic functions such as ANC, hearing ambient sounds, sound quality, and call quality. Furthermore, it almost included all the functions that wireless earphones can provide, and on top of that, it even added new features that were not seen in earphones before. I think the Liberty 3 Pro will maintain its position as the best cost-effective product among mid-to-high-end products. Next, the downside. Actually, I liked most of the basic functions such as ANC, sound quality, and call quality. However, when it comes to new features, I had some small expectations. Features like sports functions or posture reminders were more useful than I thought. But in my case,

I find it difficult to access the health features by using the app as I mainly use a smartwatch. Of course, I think those without a smartwatch could utilize these features more easily. I believe having these functions is much better than not having them, so I don't even consider it a disadvantage. If more diverse health functions can be added here, in the near future, there will be many more things that can be utilized even with earphones. By the way, for your information, Apple iPhone users may feel disappointed as they still cannot use Eldec. Moving on to the price, Liberty 4 is being sold in the range of 150,000 KRW based on the shooting. I will attach a link in the video description, so if you are interested in Liberty 4, please check it out.

I personally think that the anchor has once again released very cost-effective earphones. If you are looking for good earphones in the price range of 100,000 won, it would be very satisfying to use. This video ends here. There is no perfect product in the world. After watching the video, I hope you consider your preferences and budget carefully. The choice is always yours. So, I hope you make a rational purchase today. I'll say goodbye. Have a successful shopping day. Thank you.
