1945, Dr. Fritz Sennheiser and his seven researchers set up this company. R&D personnel carried out research and development work in Winne Bostel, a small village in Lower Saxony, Germany, which quickly attracted the attention in this field.
Headquartered in Winnipeg Bostel, Sennheiser Electric Co., Ltd. has become a symbol of this town. Its production plants include two in Burgdorf (producing electronic equipment and radio technology equipment), an earphone factory in Tullamore, Ireland, and a branch factory in Albuquerque, USA, which specializes in producing radio technology equipment for America. Products are sold by partners and subsidiaries all over the world. In 2004, the company's turnover reached 262 million euros, of which 83% came from outside Germany.
Sennheiser's products include microphones, high-fidelity wireless technology products and headphones, as well as multi-party telephone technology, information science, infrared systems, products specially provided for the hearing impaired, headphones for aerospace services and so on. In addition, Genneumann, which features studio microphones in Berlin, K+H sales and development company (speakers and studio monitors) in Denmark and joint venture Sennheiser Communication Company also belong to Sennheiser Group, which mainly develops headphones for personal computers, offices and call centers.
Sennheiser is the representative of European earplug headphones, and its sound style tends to be plain and true. It has always been known for its excellent sound quality. In recent years, more and more attention has been paid to product fashion, industrial design and product appearance. Sennheiser has a complete product line of earplugs and headphones. In China, MX series earplugs are the most famous.
At present, many of Sennheiser's low-end earplugs and earphones are designed and produced by Fengda Company, but these products still maintain the rigorous style of Sennheiser.
Sennheiser's earplug products are mainly MX series, and earphone products are HD series and PX series. And the product line is very complete. At present, the products visible on the market mainly include:

Second, the iron triangle in NBA history The iron triangle in the past:
1980- 1992 Celtic = bird+mchale+parrish.
1982- 1989 Lakers = Johnson+Jabbar+Worthyfield
1995- 1998 Bull = Jordan+Pippen+Rodman
1996- 1998 Rocket = Olajuwon+drexler+Buckley.
Today's iron triangle:
Sun = Nash+Marion+Stoudemire
Spurs = Duncan+Parker+Ginobili
Mavericks = Nowitzki+Terry+Howard
Heat = Wade+O 'Neal+Walker
Wizards = Arenas+jamison+Butler
Piston = Billups+Wallace+Hamilton
Rockets = McGrady+Yao Ming+Battier
Nets = Carter+Jefferson+Kidd
Clippers = brand+castle+Mobry.
Bumblebee = Paul+Peja+Chandler
King = Martin+Miller+Bibi
Warriors = Davis+Jackson+Harrington
Bull = Gordon+Hinrich+Raul Deng
Nuggets = Anthony+Iverson+Camby
Jazz = Boozer+kirilenko+Williams.
Celtics = Pierce+Allen+Garnett
Third, what is the position of the iron triangle in the earphone brand? These three earphone brands are world-famous brands, and the high-end headphones are impeccable and perfect. In the earphone family, Sennheiser has an unshakable position and is the industry leader. However, the status of Sony and Iron Triangle has always been questioned by earphone lovers, because headphones such as AKG and Bayer Power have a longer history and are favored by many consumers, so headphones rank not only first in the world.
On the question of cost performance, I think it is hard to say that Sennheiser is the cheapest high-end headphones on the market at present. At present, as long as the HD650 is 2700, it is the highest-end earphone of Sennheiser retail, and the ATH-A950LTD of Tiesanjiao is 2630, and this is only the high-end monitor headphones of Laotie. There are still many headphones with a price of more than 4,000 yuan, especially the ESW mahogany series headphones with iron triangle. It is more civilized to use noble headphones. Sony's headphones do occupy a place in the high-end ranks, but the low-end ones are not ideal. There is still a certain gap between the reputation of its products and the above two models, so I think Sennheiser is undoubtedly the best choice for consumers.
The landlord likes ear-hanging headphones. Among these three brands, the iron triangle is the most, and Sony and Sennheiser are rarely concerned. The low-end ear hook of the iron triangle is too worn and the high-end ear hook is too expensive, which is not a good choice. However, if the landlord likes it, ATH-EM9d has good performance and outstanding midrange, which is suitable for a variety of music styles, but the price is 165438+. Generally speaking, I think that the ear-hanging headphones have serious sound leakage and are not suitable for some occasions. Earplugs and headphones are better closed, and the price of 1000 yuan is reasonable, but this is only a reference, and the landlord can consider it.
I hope it will help the landlord.
Fourth, the history of headphones 188 1 year headphones have nothing to do with music.
65438+ In the 1980s, the world's first earphone was born, but it had nothing to do with music, but was born for communication. When you use it, you need to carry a few kilograms of headphones on your shoulders, just like carrying a speaker on your shoulders.

1968 Koss's first electrostatic headset

1979 Here comes the Sony Walkman.
Speaking of the big events in the history of headphones, we have to mention the appearance of Sony Walkman. Just like the strong wind in spring, it blows at night, and the streets are full of young people wearing headphones, fashionable and arrogant!
1980 Earplugs and Headphones
Handsome men and beautiful women no longer have to worry about their hair being messed up by heavy headphones, but the peak of earplugs did not come until Jobs introduced the iPod a few years later.
1997 Sony rear headphones

Anti-noise headphones in 2000
Bose's anti-noise earphone Quietfort for the public allows users to enjoy their own music world whether on a roaring plane or in front of a noisy TV.
