Three generations of Huilian 247(A8).
The Third Generation Huilian 247(A8 Red Bee Edition).
Third generation Huilian 247(A6pro).
These three models are all high-end models currently equipped with Huilian chips. A6pro has one more gyro engine than the first two, which can experience the real sound following effect (of little use), but it is not recommended in terms of battery life, stability and price friendliness.
In addition, the high version of Huilian is actually quite clear. In fact, it is an A8, which uses 247 series chips, so the routine that often appears is to use Huilian 106 chip products to enter Huilian 247, exaggerate 106 chip, and say that it is beyond 1562A chip, and sell A6+ at a high price for profiteering.
However, these two chips of Huilian (106 and 102) can be said to be the chips of Huilian's small experiment to enter Huaqiang North market, and they are not comparable to the chips of big brother Roda (1562A). The upgraded 247 series is not only optimized in Bluetooth transmission, but also more prominent in details, which can compete with Roda 1562A, and its function optimization is more fruity.
The third generation 1562A original shell version: the chip is equipped with 1562A, which has the appearance of the original shell, but the original shell is also divided into true and false, depending on the antimagnetic effect, whether it can really be the same as the original shell. Many so-called original shells are only imitations of appearance, but the real original shell is the third generation. As far as I know, the solution provider is not the mainstream Hao Rui, and there was one before. In short, this version has not been widely circulated in the market at present.
Third Generation 1562A Bull Edition (there are also chaotic cows like Red Bull in the market): An upgraded version of HR. If you can buy high quality, the price of more than 200 yuan is highly recommended to start with the third generation. The overall after-sales rate of this model is very low, the comprehensive experience is very good, and some upgrades have been made.
However, when promoting him, many people brag, such as using the chip Roda 1562A+, but there is no so-called Roda 1562 a+, and they also say that there is a wind noise prevention design, which can completely eliminate wind noise.
