I’ve a query for you. Which got here first — music or headphones? I guess you’ll say, “The reply is music, in fact, as a result of people had been singing songs, enjoying flutes produced from bone, and pounding drums utilizing something they might pound tens of hundreds of years in the past.”
My response to that is, “You’re so sharp that you’re at risk of reducing your self!” You recognize that, within the context of those columns, I’m speaking about music performed by electromechanical or digital means.
Like most issues, the reply to this query is extra concerned than you would possibly suppose. For instance, the prolific American inventor and businessman Thomas Alva Edison created the primary phonograph that was able to recording and enjoying again sound in 1877.
As an apart, 20 years earlier in 1857 (which was precisely 100 years earlier than I made a decision to grace the planet with my presence), the French inventor Édouard-Léon Scott de Martinville invented a tool referred to as the phonautograph that would file sound, though it could not play it again. Now, your knee-jerk response is perhaps, “Nicely, that’s the French for you,” however I worry you’d be being unkind. Scott’s phonautograph recorded sound as “squiggles on paper,” ensuing within the first means people may “see” and visualize sound.
As one other apart, in 2008, scientists managed to transform considered one of Scott’s phonautograph recordings captured in 1860 again into sound. In line with Wikipedia:
The recording, a part of the French people track “Au clair de la lune,” was initially performed at a pace that produced what gave the impression to be a 10-second recording of the voice of a lady or youngster singing at an odd musical tempo. The researchers main the venture later discovered {that a} misunderstanding about an included reference frequency had resulted in a doubling of the right playback pace, and that it was truly a 20-second recording of a person, most likely Scott himself, singing the track very slowly.”
However we digress…
Early phonographs utilized massive acoustic horns to amplify sound mechanically, with no electrical energy required; due to this fact, headphones wouldn’t have been a lot use on this context. It wasn’t till across the mid-Twenties {that a} convergence of applied sciences, together with vacuum tube amplifiers and electromagnetic loudspeakers, resulted in a big surge in each phonograph and file gross sales (see additionally my Vunderful Vacuum Tubes column).
Now I’ve one other query for you. The place did the “cellphone” a part of “headphones” come from? I guess you haven’t contemplated this poser earlier than — most individuals simply take it without any consideration — however I’m glad to clarify all (the actual trick is to cease me speaking).
The primary phone patent was granted to Alexander Graham Bell in 1876, after which phone know-how rapidly superior. For instance, in accordance with StateTech, “The primary-ever handbook switchboard, constructed from ‘carriage bolts, handles from teapot lids and bustle wire’ debuted in New Haven, Conn., in 1878. It serviced 21 subscribers, who paid $1.50 per thirty days to be a part of the change.”
It wasn’t lengthy earlier than phone switchboards had been bobbing up everywhere. Phone operators wanted to maintain their arms free to make connections whereas concurrently listening to their prospects. The answer, devised circa the Eighties, was a tool that held the receiver portion of the phone in opposition to one ear. This gave rise to the singular time period “headphone.”
Later, within the early 1900s, wi-fi telegraph operators started utilizing a pair of phone receivers — one over every ear — to hearken to the telegraph indicators. Thus, it wasn’t lengthy earlier than the plural type “headphones” made its means into widespread utilization.
In the meantime, the “cans” portion of the title to this column dates to the Forties, presumably earlier, and has its roots in radio and audio engineering tradition. Early headphones had been massive, that includes steel or Bakelite earcups linked by a headscarf, they usually bore a resemblance to tin cans in each form and really feel. The time period “cans” was utilized by radio operators and recording studio engineers throughout the mid-Twentieth century. It gained reputation within the Forties and Nineteen Fifties, significantly in navy communications and broadcast studios, the place cumbersome, over-ear headphones had been commonplace.
As an apart, I recall the introduction of the Sony Walkman within the early Eighties. These light-weight, compact, and smooth transportable cassette gamers revolutionized the way in which folks skilled music. Not like the standard shared expertise by radios, automotive stereos, or dwelling hi-fi techniques, the Walkman allowed you to stroll, jog, journey a practice, or sit in a park with your individual private soundtrack.
The explanation I point out this right here is that the Walkman popularized light-weight headphones with foam-covered earpieces, which changed the massive, clunky headphones used at dwelling. This created a brand new “aesthetic” and made headphone listening extra frequent and accepted in public. I bear in mind seeing a Walkman with two headphone jacks, which made it attainable to share your soundtrack with a detailed good friend (I couldn’t afford one, however I actually, actually needed one).
Fashionable headphones are triumphs of know-how, however retro headphones ooze model, and you may’t put a value on model. Really, that is not strictly true. On this case, because it occurs, you can put a value on model — all you must do is seek for “vintage headphones” or “classic headphones” on eBay.
That’s exactly what I did a few years in the past. I picked up a pair of Twenties headphones, unscrewed the earpiece covers, eliminated the unique magnetic transducers, and changed them with dynamic drivers I scavenged from an affordable and cheerful (~$10) pair of headphones I bought at Walmart.

The again of a closed earpiece housing is seen in the course of the above picture. The open entrance of the opposite earpiece housing, which is product of steel, seems barely decrease and to the left. Contained in the open housing is the fashionable dynamic driver sitting on insulating white foam.
Above the open housing is the screw-on Bakelite cowl, which has holes to permit sound to cross by whereas providing safety to the parts inside. To the left of the open housing is a black foam pad that sits between the dynamic driver and the Bakelite cowl, maintaining mud, particles, and detritus out. The reassembled headphones are proven within the picture under.

I do know this can sound stunning (no pun meant), however these headphones are surprisingly snug and their audio high quality is remarkably good. Better of all, they embody “classic cool” and exude character.
Let’s put it this manner: When you had been to walk round an embedded engineering convention together with your greatest pair of contemporary headphones draped round your neck, how many individuals do you suppose would touch upon how cool they appeared? Precisely — none. By comparability, I can attest from private expertise that the headphones proven above appeal to a variety of consideration and spark quite a few conversations.
