Kaiyin (formerly known as Spark) is a veteran HiFi audio manufacturer in China, affiliated to the world's top 500 enterprise Aviation Industry Corporation of China, is the world's largest HiFi tube amplifier manufacturer, and has won many world-class honors such as the Golden Ear Award of German AUDIO magazine.
 
As a traditional manufacturer, Kaiyin's tuning on the flagship N6 appears to be neutral and solid. Unlike other warm-voice-dominated orientations, the N6 is transparent with a hint of warmth, making it more natural and appropriate to express the vocals without over-overflowing. The texture and power of the low frequencies are excellent, but the retraction speed is quick, and rock users who like the low frequencies to have a lot of loose volume may find the atmosphere insufficient. In classical music, the N6's excellent resolution can restore various instruments in an orderly manner, and the ups and downs between layers are relatively clear. However, the N6's design has a mixed reputation, and the bizarre operating logic often confuses users. In contrast, the Kaiyin i5 with Android system is more in line with user habits in terms of appearance and control, and the sound also continues the transparent and sweet style of its predecessors. Kaiyin i5 also won the 2016 HEADPHONE.GURU Editor's Choice Award, which is the best comprehensive experience among its three players, with a price of about 3,000 yuan.
