The famous line of overhead headphones from Sennheiser, which can be found with the same frequency both in the tops of studio models and in collections for music lovers and audiophiles. For example, the HD 600 and HD 650 models released at the beginning of the two thousandth are considered studio classics with verified sound, chic detail and a unique talent to convey the finest nuances of "live" orchestrations. Thanks to this set of skills, the HD 600 and 650 have registered as the first and second monitor headphones in hundreds of recording studios around the world. In parallel, music lovers became addicted to the classics, who liked their detail and liveliness. After all, many studio instruments "suffered" from excessive dryness and criticality characteristic of many monitor headphones.

In the following years, German engineers played with a successful formula, with varying success trying to strike a spark once again. In addition to a pack of monitor models, the HD series has released several very simple everyday headphones for $70 – $ 100 per pair (HD 206, HD 280, HD 559). They are also perfectly assembled and use patented direct-directional EAR converters (or Sennheiser Ergonomic acoustic refinement), but they do not pretend to feats. Rather, it is an alternative to the entry-level closed models from JBL, Sony and Panasonic.


Well, at the end of the last decade, the HD series was waiting for a technical update. Wireless connection, active noise reduction, intelligent control and a bunch of other things that seemed to be a curiosity for headphones came on the scene. To the credit of Sennheiser, they did not oversleep the revolution and did not play unnecessary elitism, making HD headphones closer to the people. As a result, the youngest wireless members of this family to one degree or another retained the branded convenience and detailed sound of their ancestors, but at the same time became more accessible. As a result, it is the Sennheiser HD 350 and 450BT models that are among the top sales of headphones and bring the company the greatest profit.
