From Sennheiser
The Sennheiser HD414 was a game-changer in 1968. In those days hi-fi headphones were all big and bulky, closed-back designs, and the compact HD414 was the industry’s first “open aire,” on-ear (supra-aural) headphone. It looked, felt, and sounded like nothing else and forecast the future direction of the headphone sound.
The sound and comfort more than lived up to the jazzy good looks. In 1970 I bought a pair of HD414s to replace my closed-back phones, and moving up to the Sennheisers was a revelation. A lot of people felt the same way and Sennheiser sold more than 10,000,000 HD414s, making it the best-selling quality headphone of all time. Although it was designed as a consumer model, the HD414 was very popular with broadcast industry professionals
