Buds, cans, on-ear, in-ear, closed back or custom-fit, there's a variety of headphone to suit every ear, every wallet and every fashion proclivity. And, despite it feeling quite new to not be able to move for fear of knocking the expensive oversized earwear from a hipster's bonce, headphones have been an essential part of any music enthusiast's tech armoury for decades.
In fact, they've been an integral part of music for well over a century, and while strapping two speakers to your head doesn’t sound all that difficult the progress from Ernest Mercadier’s telephonist’s tool to Dr. Dre’s global empire is an oddly compelling one. Read on to find out why.
Ahead of the game (1937 to 1949)
Until WWII put an end to production, German hi-fi stalwarts Bayerdynamic invented the world’s first dynamic headphones for home listening. Launched in 1937, the DT-48 remained in production (in one form or another) until 2012.
Meanwhile, across the border in Vienna, AKG (established in 1947) was busy inventing the thoroughly modern K120s. Neither pair made much of an impression but the original poster provided the template for all headphone ads since – the perfect balance of impressive-sounding tech specs and marketing mumbo-jumbo.
Revolution in the head (1965 to 1975)
Koss dominated the early part of the swinging sixties – thanks to the arrival of cheap turntables and intolerant parents - and can be blamed for the present day dirge of celebrity endorsements. The Koss Beatlesphones were nothing more than an average set of cans covered in stickers but they sold out globally and remain one of the most sought-after bits of Fab Four memorabilia.
But their dominance was to be short lived as Philips, Onkyo and Sennheiser came to the party with increasingly affordable designs that sounded good and looked the part.
The most important of which was Sennheiser ‘s HD 414, the world's first open headphones. This lightweight game changer was an instant hit, with music fans happy to ditch the bulky closed back claustrophobic cans of old and embrace a smooth clear open sound. 100,000 sets were sold by the end of 1969 and their mass appeal means they remain the most successful design of all time.
