The new HD2 15 can also be considered; It is better to use second-hand HD555. I use it myself. 550 yuan. Absolutely cool.
If you are a classical music fan, you listen to everything from sonatas to chamber music to concertos to symphonies, then you should consider the choice of headphones from the following aspects. First of all, we must have pure classical blood. Among the major earphone brands in the world, European earphones do better in this respect, such as Sennheiser in Germany, Bayer Dynamics and AKG in Austria.
AKG's headphones are the best at playing classical music, and the deep classical complex and fragrant classical atmosphere conveyed by its sound are not available to other earphone brands, which is related to the fact that AKG's designers grew up in Vienna, the city of music. The older generation of designers have rich experience in listening to live music, recording and enjoying classical music, which is incomparable to the younger generation. The intermediate frequency and sound field of AKG headphones are two prominent aspects: the restoration of the intermediate frequency is almost impeccable, with good analytical power and tiny dynamic playback, which has a unique charm in playing human voices; The sound field of AKG headphones has always been praised: wide, accurate, clear and stable. Fortunately, not only the high-grade AKG headphones have the above advantages, but also the middle and low-grade products, such as K55, K66, K70 and K 100, all inherit these advantages, but to different degrees.
AKG
K66
K66 is an entry-level monitor headphones introduced by AKG, a famous Austrian earphone manufacturer. I believe that people familiar with headphones have heard of this headset. K66 adopts semi-open design, which has the advantages of full cover opening: comfortable to wear, isolated from external noise, not limited by closed sound field, and excellent sound field and separation performance.
Lightweight design is also a highlight of this headset. K66 adopts automatic adjustment device, and the elastic soft hair band will pull the speaker to fit comfortably on the ear according to the head shape. K66 has a wide sound field performance, and the separation of musical instruments is also excellent, and female voice and chord music are one of the strengths of K66.
