Fact #1. The invention of the amplifier dates back as far as Thomas Edison. He inadvertently discovered an electrical current that could be used to transfer radio waves and produce sound. However, he didn't continue the work to bring this invention to fruition. Others built on it and created an oscillation valve that made this possible. Not long after, an American scientist added an element to this creation and made a direct-current grid. An electrical engineer linked two circuits between a stronger and weaker current, ultimately creating the amplifier.
Fact #2. In 1998, Bluetooth technology hit the scene and revolutionized the way people listen to music. The increased use of mobile devices and electronics has made things like headphone amplifiers a regular staple in the world of musicians, producers, and audiophiles.
Fact #3. These devices take the amplifier idea and condense it. They can vary in size. Some versions will fit in the palm of your hand, while other models will take up the same amount of space as a portable DVD player.
Fact #4. If you listen to the majority of your music on mobile devices, you know they lack the capability to produce the intense sound you want. One of these items will add the necessary power to turn your average headphones into high quality speakers. While most mobile devices already have an amplifier built into the system, they're rarely sufficient to produce the level of sound a dedicated audiophile wants.
Fact #5. The headphone amplifiers on the market today are compatible with most mobile devices, laptops, and desktop computers. Higher-end units can accommodate up to four sets of headphones. You'll also find that some come with USB ports. These are helpful for streaming and file transfers. One of the biggest advantages to using these is that it allows for precise adjustments. You can customize your audio experience.
