Founded in 1945 as one of the four major headphone brands, Sennheiser is recognized as the world's leading manufacturer of professional microphones and headphones, and a pioneer in radio, infrared transmission technology, auscultation, aviation calls, multimedia communications, call center headsets and headsets. In the "Best Over-Ear Headphones Under $400" list on the review website The wirecutter, the Sennheiser Momentum 2.0 ("second-generation wooden manju") was recommended. Compared with over-ear headphones in the same price range, the Momentum2.0 foldable design makes it more portable, and the stylish retro design allows you to wear it on the street and earn enough eyeballs. If Audio-Technica msr7 is more extreme towards vocals, then Momentum2.0 has a balanced three-frequency performance, which is more suitable for "omnivorous", that is, music enthusiasts who listen to all kinds of music. If you like to be in the ear, you can choose Sennheiser IE80, which has a large sound field, good interpretation, deep low frequencies, and good high frequency extension, but the mid-frequency vocals are thin, suitable for listening to classical music. In addition, if the budget is around 2500 yuan, you can choose the well-received HD650. If there was one word to describe Sennheiser, it would be "candid", without too much embellishment. If you happen to recognize such qualities, try Sennheiser's headphones.
