HUAWEI Honor FlyPods CM - H2S Bluetooth Earphones Touch Control Earbuds - WHITE
Newly added black edition, and don’t have active noise reduction function
Based on multiple sources of information, AirPods 2 will follow the design of the first generation AirPods. However, in addition to the existing white version, AirPods 2 will also be provided with a black version. Consumers don't have to worry that the AirPods 2 they just bought is recognized as AirPods.
In addition, a layer of abrasive coating will be added to the headset body and charging box surface of AirPods 2. The touch may be similar to the fog glass used on the back cover of Pixel 3 and 1 plus 6 mobile phones. The advantage is that it can improve the scratch resistance of AirPods 2 and reduce the probability of accidental drop of headphones when moving.
Considering the release time and user reputation of the first generation of AirPods, it would be a reasonable choice for AirPods 2 to follow the current design, but this also means that AirPods 2 may not be able to add the noise reduction capabilities expected by many users.
AirPods adopts a semi-ear design originating from EarPods, which can provide comfortable and even almost "insensitive" wearing experience, but at the cost of a basic lack of passive sound insulation.
In theory, Apple can reduce noise by adding a pickup microphone inside and outside the headset and then sending out a reverse sound wave through the loudspeaker, that is, active noise reduction, but considering the size of AirPods and the "defects" of not being passively de-noised, we tend to prefer that AirPods 2 will not have much improvement in noise reduction capability.
Bluetooth 5.0, better sound quality
AirPods currently uses Bluetooth version 4.0. According to media, AirPods 2 has passed the Bluetooth Special Interest Group certification and will adopt the latest Bluetooth 5.0 standard.
But you can't be more entangled with the specific version of Bluetooth standard. AirPods has always been ahead of its rivals in terms of stability and latency of left and right ear connections, not because of the Bluetooth version, but because Apple has customized a special Bluetooth solution on AirPods: after pairing with the iPhone, the iPhone transmits audio signals to the left and right ears of AirPods respectively, thus achieving very low latency.
Behind the scheme is an "ecological moat" composed of W1 chips designed by Apple with a lot of R&D resources and Apple's own devices such as the iPhone, iPad, Mac and Apple Watch.
The addition of Bluetooth 5.0 does not mean that AirPods 2 will make great progress in stability, delay and power consumption, nor does it mean that other real wireless headphones using Bluetooth 5.0 will have the possibility to catch up with AirPods 2 in these aspects.
AirPods 2 will also continue AAC audio coding and decoding with the Apple Device Standard (zu) and chuan, but it will optimize the acoustic cavity inside the headset, and it is expected that the sound quality will be improved.
Following Apple Watch, it is possible that Apple will add more health monitoring-related features to AirPods 2 as well.
Adding health monitoring functions to headphones is not a new thing. Samsung Gear IconX (2016), released in the same period as the first AirPods, is equipped with accelerometers and heart rate sensors, which can achieve more "high-level" motion monitoring functions such as stepping and heart rate recording.
However, due to volume constraints, it is not easy to "plug" so many sensors into a real wireless headset. Samsung's Gear IconX, for example, provides only one and a half hours of service in Bluetooth. To improve the service, Samsung cut off the heart rate sensor on Gear IconX 2018, which was released later.
Of course, with the development of technology, there are more and more advanced options available on the market. Earlier, some media suggested that AirPods might use PerformTek biometrics, a technology certified by the National Institutes of Health in 2012 that could theoretically yield more accurate heart rate figures than existing PPG schemes.
Voice wake-up function
The original AirPods can wake up the Siri voice assistant via double clicking the earphones, so the operation is not very convenient. On AirPods 2, Apple will add the ability to voice-wake up Siri directly by saying "Hey Siri". Users can use Siri to control music playing, adjust the volume and search information without touching the headphones.
Similar to the iPhone, iPad and Mac (built-in type of T2 chip), the "Hey Siri" of AirPods 2 can only recognize the wearer's voice after input, thus avoiding false awakening. Speech recognition is implemented directly on the earphone.
Support wireless charging function
The battery capacity of AirPods is very small (93 mWh for each earphone and 1.52 Wh for charging box), but with the ultra-low power consumption of the W1 chip, the endurance performance of AirPods is still excellent in the current real wireless headphones, while the endurance of AirPods 2 will be consistent with that of AirPods. The endurance of the headphones themselves will last for about 5 hours, and can reach 24 hours with the charging box.
In addition to wired charging through the Lightning interface, the charging box of AirPods 2 will also add QI wireless charging function, which can charge the AirPods 2 via the wireless charging pad.
Higher price and will be released in September
The cost of AirPods 2 is significantly higher than that of first-generation products due to the many new features, so Apple is likely to increase the price of AirPods 2, which is expected to rise from $159 to $199.
As for the release date, there are two rumors: the first is that AirPods 2 will be released at Apple's Spring New Product Release event in March, and the second is that it will be released at the Autumn New Product Release event in September.
