AKG is a traditional and established headphone manufacturer, with deep technical accumulation in headphone manufacturing and tuning, both in terms of craftsmanship and grasp of the overall details, it can be done appropriately. In recent years, AKG has rarely updated its headset Bluetooth headsets, and although the sound quality is still remarkable, there is a big gap between it and other brands in terms of battery life and additional features.
 
Before introducing the specific model, it is necessary to understand the several series divisions of AKG. Its K series is the flagship series and is highly sought after by enthusiasts; The N series is designed for middle-aged consumers with a certain amount of spending power, with a calm appearance and high premium; The Q series is tuned by Quincy Jones, known as the "godfather of music", and is a derivative series of the K series; The Y series focuses on fashionable design and is an entry-level product aimed at young people.
 
AKG's Bluetooth headphones have the best sound quality among the K845BT, which was recognized by VGP 2017 SUMMER. It can be seen as the Bluetooth version of the former flagship model K550, and the appearance is almost the same as the latter, with a price of 1899 yuan. The K845BT's ear cups are smaller than the K550, making it suitable for wearing on the go, and the addition of NFC also makes it easier to connect to mobile phones. The biggest highlight of the K845BT is that it adopts a large 50mm driver unit, although it does not support aptX or AAC Bluetooth encoding, but it is supported by Kleer technology. According to relevant information, the advantage of Kleer technology is that the compression of the transmitted signal is small, and the transmission distance is large.
 
In terms of hearing, K845BT continues AKG's consistent strong analytical characteristics, and on this basis, it also appropriately increases the volume of low frequencies, which is more in line with the taste of young people as a whole, and is suitable for rock music. The disadvantage of K845BT is that the Bluetooth version is 3.0, the Bluetooth transmission power consumption is large, the battery life is far lower than the industry standard of 8 hours, and it takes 3 hours to charge.
 
Although the sound quality is not as good as that of the K845BT, the Y50BT can be said to be the most balanced performance among the AKG Bluetooth headphones. What is Y50BT HiFi? The award-winning products of the 2015 and 2016 equipment selection are priced at 949 yuan. It is the Bluetooth version of the brand's classic Y50, with a simple and fashionable colorful body, but considering the need for portability, the ear cups of the Y50BT are also smaller than the Y50, with a battery life of 20 hours and support aptX and AAC Bluetooth coding. The Y50BT has excellent sound quality, strong resolution, and rich details are also well organized and layered, which is more suitable for pop music.
 
In addition to the K845BT and Y50BT, AKG's Bluetooth headsets on sale also include the Y45BT and N60NC Wireless. The configuration of Y45BT is basically the same as that of Y50BT, but the fuselage is lighter, the battery life is only 8 hours, and the price is 749 yuan. N60NC Wireless is a noise-canceling headphone, supports aptX and AAC Bluetooth encoding, and the battery life is also not strong, with Bluetooth and noise cancellation turned on, it can last for about 15 hours, and the price is 2499 yuan.
