Sennheiser is known for producing high-quality headphones and microphones that are almost unknown in the audio world. As early as 1955, Sennheiser released the brand's first noise-canceling microphone, and Sennheiser's professional audio systems were also used in Broadway studios in New York and Abbey Road in London. In China's headphone market in 2018, Sennheiser ranked second in terms of market share.
 
In the early years of the automotive Bluetooth headset market, many audio manufacturers, including Sennheiser and BOSE, had a place, but with the popularity of smart phones and the gradual increase in the popularity of wireless music headphones, communication headphones with a single function began to become chicken. At present, Sennheiser and BOSE have launched true wireless earphone products with microphones, and have reduced investment in the communication earphone market, of which BOSE has completely withdrawn from the car Bluetooth headset market.
 
Sennheiser still has a line of automotive headphones, but it hasn't been updated for several years, and currently only one of the brand's headphones, PRESENCE Business, has been retained. Compared to other products on the market, the PRESENCE Business has a slightly old-fashioned appearance, but the acoustic performance of the headphones is worth affirming. In an early evaluation of wirecutter, the PRESENCE Business took second place, and its call quality is still a flagship today, with good sound performance in driving, office, and outdoor environments.
 
Now Sennheiser has not followed up on the sales strategy of other brands, and the price of PRESENCE Business is still high, the standard version is priced at about 1600 yuan, and the UC unified communication version is priced at about 2200 yuan, which is not cost-effective.
