It might seem crazy to think of today, but what if the headphones of the future looked more like hearing aids – more of a permanent device than one we carry around with us and have to put on and take off? Now, the audio quality of headphones increased and people were able to wear them comfortably for long-term wear. 1979: The Walkman Original Walkman headphones (From: MAAS Museum) Following Baldwin’s refusal, Wireless Specialty Apparatus Co. took advantage of the situation by deciding to build a factory in Utah, manufacture Baldwin’s headphones, and sell them in the United States. Navy, but only at the initial price, which was never to be increased under any circumstances. 1937 Headphones started with phone operators - It was a single earpiece that rested on the user’s shoulder and weighed over 10 pounds.

Lightspeed Aviation 30 3G Discontinued Aviation Headset". lightspeedaviation.com . Retrieved 26 Dec 2020. A headphone is so much more than just a medium for media consumption. It is an extension of one’s personality. From a luxury to a necessity, one cannot deny the need to have at least one pair of headphones today. Headphones have a special place in every music lover's life. Planar magnetic (also known as orthodynamic) headphones use similar technology to electrostatic headphones, with some fundamental differences. They operate similarly to planar magnetic loudspeakers. Artists on stage once used floor monitor speakers to hear their performance and stay in sync with others. These speakers became harder to hear as stages grew louder from instruments and PA systems in the new millennium. What's more, artists who could now move around with wireless microphones and guitars may have felt tied down to the stationary speakers. This period also can be considered a part of the Koss era because all these years were marked by Koss’s achievements and innovations.
What could the future of headphones look like?
Hearing risk from headphones' use also applies to workers who must wear electronic or communication headsets as part of their daily job (i.e., pilots, call center and dispatch operators, sound engineers , firefighters, etc.) and hearing damage depends on the exposure time. The National Institute for Occupational Safety and Health ( NIOSH) recommends sound exposure not exceed 85dB(A) over 8 hour work day as a time-weighted average. [65] NIOSH uses the 3-dB exchange rate often referred to as "time-intensity tradeoff" which means if sound exposure level is increased by 3 decibels, the duration of exposure should be cut in half. NIOSH published several documents targeted at protecting the hearing of workers who must wear communication headsets such as call center operators, [66] firefighters, [67] and musicians and sound engineers. [68] [69] See also Electrostatic drivers consist of a thin, electrically charged diaphragm, typically a coated PET film membrane, suspended between two perforated metal plates (electrodes). The electrical sound signal is applied to the electrodes creating an electrical field; depending on the polarity of this field, the diaphragm is drawn towards one of the plates. Air is forced through the perforations; combined with a continuously changing electrical signal driving the membrane, a sound wave is generated. Electrostatic headphones are usually more expensive than moving-coil ones, and are comparatively uncommon. In addition, a special amplifier is required to amplify the signal to deflect the membrane, which often requires electrical potentials in the range of 100 to 1,000volts. Wired headphones are attached to an audio source by a cable. The most common connectors are 6.35mm ( 1⁄ 4 inch) and 3.5mm phone connectors. The larger 6.35mm connector is more common on fixed location home or professional equipment. The 3.5mm connector remains the most widely used connector for portable application today. Adapters are available for converting between 6.35mm and 3.5mm devices. Just like what happened in the ‘80s with the emergence of the Walkman, the rise of the iPod and mp3 players led to a huge growth in the market for cheap, lightweight earbuds that has largely continued until today. 2004: Bluetooth Revolution Bluetooth logo (From: bluetooth.com)

Today they are typically used only in in-ear headphones and hearing aids, where their high efficiency and diminutive size is a major advantage. [45] They generally are limited at the extremes of the hearing spectrum (e.g. below 20Hz and above 16kHz) and require a better seal than other types of drivers to deliver their full potential. Higher-end models may employ multiple armature drivers, dividing the frequency ranges between them using a passive crossover network. A few combine an armature driver with a small moving-coil driver for increased bass output. Beats, UrbanEars, Skullcandy and more turned headphones from utility to fashion statement with bright colors, big headphones and expensive price tags. Pretty much every celebrity had a headphone affiliation at one point, with some of them making a pretty penny on acquisitions in the space. Binaural recordings use a different microphone technique to encode direction directly as phase, with very little amplitude difference below 2kHz, often using a dummy head. They can produce a surprisingly lifelike spatial impression through headphones. Commercial recordings almost always use stereo recording, rather than binaural, because loudspeaker listening is more common than headphone listening. a b Smith, Caspar (30 October 2011). "Now hear this: the history of headphones". The Guardian. Archived from the original on 13 September 2017 . Retrieved 13 September 2017. After the success of the first headphones, a set of in-ear headphones was invented and patented by a French engineer Ernest Mercadier, who improved the area of telephone reception by implementing handsfree headphones and was awarded for that. The new improved headphones were a success due to their weight, which was significantly lower than the weight of the first headphones, and that made them easier to use. The main reason for weight reduction was the installation of miniature receivers, which weighed less than 1.75oz. The receivers were adapted to human ears, which made the insertion easier, especially due to a rubber cover. These headphones can be considered the first ancestor of the modern in-ear headphones.
Dynamic headphones & stereo improve sound quality
Screaming babies and loud snorers met their match when Bose unveiled their QuietComfort line. Though pilots had been using noise-cancelling technology for decades, now passengers could also get some relief on loud flights (or in front of the TV with a nagging spouse). Source The year 1958 is significant in the history of headphones because it is the year when the first hi-fi stereo headphones were created. The year 1958 is one of the most important years in the history of headphones since it’s the year when the first hi-fi stereo headphones were created. Innovative and ahead of its time, the Electrophone was a subscription service in London. It allowed users to listen to live theatre performances using their telephone line.

Just like any other technology, headphones didn’t become a huge industry overnight. Way before MP3 files and premium Spotify accounts, headphones had little to do with music at all. It took decades of innovation to turn this technology into the headphones as we know them today. Fligor, Brian J.; Cox, L. Clarke (December 2004).

Almost two decades later, some of the industry’s future leaders took their place and altered the course of headphone history. Beyerdynamic, the company that produced the first dynamic headphones on the market – the DT-48 – was the first pioneer. Dynamic headphones are still the most popular type of headphones on the market today. This particular model is still available. 1949 Although modern headphones have been particularly widely sold and used for listening to stereo recordings since the release of the Walkman, there is subjective debate regarding the nature of their reproduction of stereo sound. Stereo recordings represent the position of horizontal depth cues (stereo separation) via volume and phase differences of the sound in question between the two channels. When the sounds from two speakers mix, they create the phase difference the brain uses to locate direction. Through most headphones, because the right and left channels do not combine in this manner, the illusion of the phantom center can be perceived as lost. Hard panned sounds are also heard only in one ear rather than from one side.
