Fact #1. The first effective headphones date back to 1910, when an inventor assembled a pair in his kitchen. These primitive headphones were similar to telephone receivers. They did a poor job of reproducing sound relative to modern standards. They were almost exclusively used by telephone operators until the late 1920s.
Fact #2. The smaller earbud design used by many air travel headphones manufacturers originated with hearing aids. This alternative to full-size headphones was frequently paired with the first portable transistor radios of the early 1960s. Transistor radios were the first audio devices to feature the 3.5 millimeter audio plug used by most headphones today. As the output quality of audio devices improved, demand for high fidelity headphones increased. CD players and modern digital and streaming devices reward users of high quality models.
Fact #3. As manufacturers made audio devices smaller and easier to carry, passengers brought them, and headphones, aboard airplanes. Noise canceling and noise isolating headphones were ideal for use during flight. This was thanks to their ability to block or drown out engine sounds.
Fact #4. Most popular headphones for travel employ either noise canceling or noise isolating technology. Noise canceling units monitor ambient sound with built-in microphones and invert the sound with an onboard processor. This inverted sound is almost instantly fed into the user's ear, effectively canceling out surrounding noises. This technique is particularly effective with consistent, droning sounds like the hum of an airplane jet engine. However, these headphones struggle to cloak higher pitched sounds like crying babies or talking.
Fact #5. Noise isolating headphones use a simple solution to limit outside noise. They merely offer a barrier between your ear and those unwanted sounds. Over-ear headphones feature sound-dampening insulation, but typically aren't as effective at isolation as in-ear or earbuds style headphones.
