Audio-Technica headphones are simple and delicate representatives of Japanese style, and the shape of Asian female voices with the log cavity has won the titles of "iron taste" and "female poison". In addition, Audio-Technica's high-end headphones are mostly made of raw wood, polished and lacquered, and the workmanship is first-class, and it is known as the "furniture factory" in the earphone enthusiast circle.
 
When it comes to Audio-Technica's earbuds, we have to mention the CKM series. It used to be the highest-positioned earbud series in Audio-Technica, with a titanium alloy shell, luxurious packaging and exquisite workmanship, but due to the average resolution of the earbuds in this series and the extreme tuning, it was not popular until it was finally forced to pause. After a period of suspension of the CKM series, the successor CKR series came into being. CKR is positioned as a consumer-grade dynamic headset, and the product is characterized by reproducing the real original sound and clear and beautiful human voice. There are three Bluetooth earbuds under the series: CKR75BT, CKR55BT and CKR35BT, and they are also the three main music Bluetooth earbuds of Audio-Technica. In addition, the CKR75BT is the VGP 2017 Gold Award model and the CKR55BT VGP 2018 SUMMER Award winning model.
 
The three Bluetooth earbuds of the CKR series have a battery life of up to 7 hours, and the Bluetooth version is 4.1, and their differences are mainly in the unit diameter, frequency response range, Bluetooth code and impedance. Both CKR75BT and CKR55BT support aptX and AAC Bluetooth encoding, CKR35BT only AAC Bluetooth encoding is supported. And because the unit diameter and impedance of the three Bluetooth earbuds of the CKR series are slightly larger than those of other brands of Bluetooth headsets, the power consumption is larger when listening to songs, in order to maintain a good battery life, these three headphones have added a battery box to the headphone line, and portability has been sacrificed.
 
In terms of actual hearing, the tuning of the CKR75BT is different from the consistent "female poison" of the Iron Triangle, in which the high frequency is softer, and the low frequency volume is also significantly increased, which is more suitable for the listening preferences of ordinary consumers. The performance of the CKR55BT is also relatively balanced, with no obvious bias, the mid and high frequencies are not prominent, the vocal performance is moderate, and the low frequencies are slightly inferior to CKR75BT. The sound of the CKR35BT is more entry-level than the previous two, but it's still good compared to its price point. In terms of price, the three are 1099 yuan, 799 yuan and 518 yuan respectively.
 
Among the Audio-Technica Bluetooth earbuds, the DSR5BT is positioned higher than the CKR75BT, which is a VGP 2018 SUMMER Gold Award model, and the biggest feature is the use of all-digital drive technology and dual-phase push-pull unit. To enhance the dynamic range of the DSR5BT, Audio-Technica also added virtual voice coil technology to the DSR5BT, using a D/D conversion chip developed by Audio-Technica in collaboration with a semiconductor company. DSR5BT supports aptX and AAC Bluetooth coding, the sound has the characteristics of rich detail and high definition, and its sound field is wide, medium and high frequency are transparent, and the low frequency volume is sufficient, but according to users, there is a slight noise floor. In other aspects, DSR5BT adopts a hard collar design, and the 8-hour battery life is not excellent compared to similar products, and the price is 2180 yuan.
 
The most "entry-level" Bluetooth earbuds in Audio-Technica are CK200BT 428 yuan, which were also selected as VGP 2018 SUMMER award-winning models. It adopts a rear-mounted design, and the weight of 14g is very light, but it does not support aptX or AAC Bluetooth encoding, and the 7-hour battery life is in the upper ranking compared to similar products. Finally, it is worth mentioning that the left earbud of the Audio-Technica rear Bluetooth earbuds has a raised dot, which is convenient for users to quickly distinguish left and right in the dark, which is very user-friendly.
