Last night Apple officially launched the long-rumored AirPods Pro, ear new design along with the long-awaited noise reduction, but the price came to 1999 yuan, with the second-generation AirPods opened nearly 500 yuan difference. After two AirPods read through the specifications and descriptions, I found this 500 difference is not expensive does not make sense.

Compared with the former, the most obvious change is that the latter uses AirPods Pro ear new design, the overall follows the white apple usual simple design, but the weight and length slightly shorter than the previous generation (30.9mm <40.5mm), (5.4g> 4g) and a width (21.8mm> 16.5mm) is greater than the previous generation. Further, AirPods Pro cartridge charging becomes more "flat", but the overall volume or more "slimmer" than the other ear noise canceling headphones market charging case.
In order to make use of in-ear design AirPods Pro to wear more comfortable, AirPods Pro choice of three different sizes of silicone earbuds to fit the size of the ear cavity, but also with the help of built-in "ventilation system" balance the ear cavity internal and external pressure, improve wearer comfort. Apple's official website to introduce in this: "These internal tapered design of ear plugs will fit your ears, for the AirPods Pro can be worn in the ear always firmly coupled with the ventilation system to help balance the pressure, you will wearing. there is a feeling like nothing. "
In contrast, semi-open design of the second generation AirPods even though it can prevent ear headphones to give the "ear swelling sense", but it also makes it impossible to fully adapt to everyone's ears after me because Apple had to wear the AirPods out and eventually give up easily use. One of the important reasons In addition, semi-open design in the absence of physical passive noise reduction, it is difficult enough to achieve excellent noise reduction effect, which is why we often poorly on the first / second generation AirPods brought sound effects .
And we finally see the noise reduction is a natural thing in the use of in-ear design AirPods Pro.
除了入耳式设计带来的物理降噪以外，AirPods Pro 也具备主动降噪功能，可根据耳部的几何结构和耳塞的佩戴贴合度持续进行调节，以阻隔外界噪音。外向式麦克风会检测外部声波，随后采用与之相当的抗噪声波将其抵消，从而实现降噪；内向式麦克风会检测你耳内是否有多余的声波，然后同样用抗噪声波予以抵消。
而且和市面上其他降噪耳机一样，AirPods 也支持模式切换，可以在“降噪模式”和“通透模式”之间切换，后者可以暂时关闭耳机的降噪功能，让外界的声音进入耳机，从而让你在和身边的人交谈时更加自然。
和第一/二代 AirPods 不同，AirPods Pro 的交互由耳机本体转移到耳机柄的力度感应器上，并支持更多的手势控制，例如按一下播放/暂停或接听电话、按两下跳至下一首曲目、按三下跳至上一首曲目、长按则在主动降噪与通透模式之间切换。
但降噪功能也意味着更大的耗电量，和第一/二代 AirPods 相比，AirPods Pro 单次充电的聆听时间只有 4.5 小时，稍弱于前代的 5 小时，但配合充电盒的话依旧可以实现 24 小时的聆听时长以及充电 5 分钟增加 1 小时聆听时长的效果。
除了降噪以外，AirPods 的音频能力也得到提升，通过定制的高振幅、低失真度扬声器驱动单元，AirPods Pro 可实现浑厚有力的低音，而内向式麦克风则可帮助调节中频和低频部分，优化音频输出；放大器会推动扬声器驱动单元，来消除背景噪音，并与 H1 芯片相互配合来控制声级。而通过扩大麦克风网状声孔，也提升了有风环境下的通话清晰度。
AirPods Pro 还达到 IPX4 抗汗抗水等级，能够保证运动和日常使用的耐用性。第一/二代 AirPods 则没有达到任何抗水抗汗等级认证。
最后总结一下，AirPods 和 AirPods Pro 相同之处如下：
1. 采用 H1 芯片，支持“嘿,Siri”功能；
2. 支持摘下暂停，戴上播放功能；
3. 充电盒支持无线充电。
