The H2 chip makes domestic manufacturers daunting

In the early morning of September 8, Apple brought the new AirPods Pro noise-cancelling headphones at the autumn new product launch conference. Although the appearance is almost identical to the previous generation, it has also brought many upgrades. The most eye-catching is noise reduction. The effect is doubled. For commuters who often need to crowd the bus and subway, they should be able to obtain a quieter and more comfortable listening experience. In addition, the new headphones have also been upgraded in terms of sound quality, control, battery life, etc., but the price is 100 yuan cheaper than the previous generation to 1899 yuan, which is really hard not to be excited. Once the product was released, it attracted a lot of onlookers and discussions among netizens. Most of them recognized and loved it and decided to buy a new generation of AirPods Pro. As a product that has been iteratively updated after three years, AirPods Pro 2 does show Apple's intentions and sincerity, and this may become another explosive model. Of course, the new product can achieve such a significant upgrade in terms of sound quality, noise reduction, battery life, etc. The new H2 chip that Apple was willing to pull out after three years of polishing must have contributed. (Source: Apple official) So, how powerful is Apple's self-developed H2 chip? Are AirPods Pro 2 really worth buying? Let Xiao Lei answer it for you.

H2 chip brings new life to AirPods Pro

Since Apple has not officially announced too many details of H2 chip, Xiaolei from blogger @ Douroom Tinglan learned that the H2 should be based on TSMC's 7nm process. The biggest advantage is the increase in chip computing power. Of course, the power consumption performance is bound to be stronger than the previous generation. The outstanding performance of Apple's H1 before has allowed AirPods to dominate the Bluetooth headset market for several years. This H2, which was launched after three years, and has a new process blessing, will definitely be significantly ahead of the previous generation. Everyone knows that the computing power of the Bluetooth chip will directly affect the resolution, noise reduction depth, and noise reduction bandwidth of the earphones. Apple officially stated that the H2 chip supports up to 48KHz audio, which is the level of lossless sound quality, which improves the status quo of the relatively weak sound quality of Bluetooth headsets in one fell swoop. At the same time, the H2 chip also adds an adaptive computing audio algorithm, which can quickly process the audio before you hear the sound, improve the high fidelity of the sound quality, and cooperate with customized drive units, customized amplifiers (independent DAC), etc., the sound quality of headphones There should be a very significant improvement. (Source: Apple official) It is worth mentioning that AirPods Pro 2 also introduced an adaptive equalization function to reduce the impact of user ear canal differences and wearing differences on sound quality. You can use the TrueDepth camera on the iPhone (that is, the 3D structured light function) to create personal contour information based on the geometry of the head. The H2 chip will perform special calculations based on the shape of each person's ears to achieve high-fidelity sound quality as much as possible. Needless to say, the personalized spatial audio based on dynamic head tracking is mainly to improve the immersive experience of users when listening, and may get better results on the AirPods Pro 2 equipped with the H2 chip. Another major upgrade brought by the H2 chip is that the noise reduction effect has been increased by 2 times. The noise reduction of the first-generation AirPods Pro is actually quite good. The new machine not only has stronger computing power, but also reduces noise by optimizing the acoustic algorithm. The fuselage structure optimizes the position of the noise-cancelling microphone and the rear air vent, which can quickly detect the in-ear sound and cancel the noise. In the adaptive transparency mode, the chip can reduce noise 48,000 times per second, greatly reducing the noise intensity of horns or power tools such as cars, so that you can effectively filter some high frequencies when you can hear the ambient sound clearly. Harsh noise. (Source: Apple official) The transmission performance of the H2 chip has also been upgraded to support the latest Bluetooth 5.3, with higher transmission bandwidth and lower latency, which is the greatest guarantee for lossless audio transmission. At the same time, H2 also has better energy efficiency performance. The use time of AirPods Pro 2 with noise reduction mode enabled has been increased from 4.5 hours of the previous generation to 6 hours. With the charger, you can get 30 hours of listening time, which is 6 hours more than the previous generation. , the improvement in battery life is quite significant. In addition, this headset charging box also adds the MagSafe wireless charging function, which can directly use the Apple Watch charger or MagSafe charger to charge the headset, and the convenience is also improved. In addition to the above performance improvements, AirPods Pro 2 has other highlights. A new touch operation has been added, allowing you to quickly adjust the volume by sliding the headphone handle up and down without having to take out your phone. The charging box has a built-in U1 chip and speaker, which is more convenient for users to locate and find. A lanyard hole is added on the side of the fuselage, which can be used to bind the headset to the backpack. These are also the highlights of this time, and it can be seen that Apple is still more attentive to this product. (Source: Apple official) The emergence of Apple's H2 chip has greatly improved the sound quality, noise reduction, and battery life of AirPods Pro 2, and it has also brought Bluetooth headphones into the new field of "computing audio". A new era of power performance. Although new products from brands such as Huawei and Xiaomi are also exploring this aspect, they may not be as clear as Apple, and there are still some gaps in performance and experience. H2 may bring new growth opportunities to the TWS noise-cancelling headset market, but at the same time, it will also test the manufacturer's ability to adjust and optimize audio. For Apple users with needs and ideas, AirPods Pro 2 is indeed worth considering. As far as Apple products are concerned, it is worthy of the phrase "high cost performance".

stronger and cheaper is not necessarily worth buying

AirPods Pro 2 with higher performance and a price of 100 yuan cheaper does not mean It is definitely worth buying, and everyone still needs to consider their actual needs. If you are an Android phone user who wants a noise-cancelling earphone with excellent sound quality and performance, and you are attracted by AirPods Pro 2, Xiaolei still recommends you not to buy it. Many functional features of AirPods Pro 2 and the advantages of the H2 chip need to be fully utilized with the iPhone. Using this headset with Android system, the interactive experience and even sound quality and noise reduction may be weakened. Therefore, Android users really don’t need to consider AirPods Pro. Sony’s noise-cancelling beans, OPPO Enco X2, etc. are actually relatively good choices, and products that are more compatible with the system can get a smoother experience. If you are a loyal Apple user, first consider whether you really need the "noise reduction function". Usually, I only listen to music in quiet environments such as companies and homes, and there is no need for commuting such as subways and buses. It may not be particularly obvious whether there is noise reduction to improve your experience. In this regard, you can actually consider the cheaper AirPods 3, which uses the same drive unit as the AirPods Pro 2, supports personalized spatial audio, and has a battery life of 6 hours/30 hours. The sound quality and experience level are not too big. difference. (Source: Apple official) The official price of AirPods 3 is 1349 yuan, and the third-party channel should drop to about 1100 yuan, which is 800 yuan cheaper than AirPods Pro 2, which is also worth considering. Moreover, AirPods 3 is also a semi-in-ear design, which is more friendly to users who cannot stand in-ear. It has to be expanded here. Those who cannot adapt to in-ear earplugs but need noise reduction function are also not recommended to buy them. At this stage, true wireless noise-cancelling headphones must be inseparable from in-ear design, which can effectively isolate a lot of noise. For these users, Xiaolei recommends the use of noise-cancelling headphones, which may have a better experience and feeling. In addition to the above situations, for those Apple users who need noise reduction and can accept the in-ear design, AirPods Pro 2 is really worth buying. As mentioned above, it has a lot of improvement compared to the previous generation, but the price has not risen sharply because of this, and it has a strong temptation. Users of AirPods Pro 1 can upgrade directly. If users of AirPods 1/2/3 need noise reduction, it is also recommended to upgrade. However, it should be noted that many AirPods Pro users reported that the noise reduction performance of the headset dropped significantly after several firmware upgrades. We do not know the specific reason, but we still remind everyone to upgrade carefully to avoid a worsening experience. (Source: Apple official) From several products this year, we can roughly see that Apple wants to expand its influence in the domestic market through price advantages and attract more users. Before the release of the iPhone 14, there were many rumors that the price would increase, but it did not come true in the end, and the AirPods Pro 2 also appeared to increase the volume without increasing the price. In the Android camp, in order to reach the high end, the price of new phones has risen year by year. The comparison between the two groups highlights Apple's advantages, and Apple products are more likely to attract consumers' attention and favor. The current market situation is quite unfavorable for Android, and domestic mobile phone manufacturers may need to come up with more competitive products in order to curb Apple's continued expansion of domestic advantages.
