AKG is almost the go-to brand for entry-level stereo headphones, with a variety of models to choose from, such as Y20U, Y50, K420, K450, Q460, etc., while it is a little weaker in advanced stereo headphones, the most worthy of which is the K550. The AKG K550 was named "Best Home Over-Ear Headphones of 2016" by the well-known audiophile website WHAT HIFI?. The K550's first impression is its size: the 50mm drivers, wide headband, and long, thick headphone cable make it less portable and suitable for home use. Although rough on the outside, it is delicate on the inside: it is comfortable to wear, without gripping the head and ears; The sound quality performance is excellent, the low frequency is well dived, the midrange is comfortable to listen to, the high frequency is soft, the resolution is strong, and the interpretation of pop music is very good. In the grade of advanced stereo headphones, the excellent use experience is matched with the price of 1000 yuan, AKG K550 can also be said to be full of sincerity.
