Wow. What a hot day today. 48C. Apparently we were the hottest place in the world today. I am a person that have a body that cant take weather over 25C 🙂
I came to think about something that a lot of people use in a lot of circumstances. A lot of us could not live without it and how would workouts and inspiration come to us in a better way than through our earphones plugged into our MP3 and Apple Audio players.
Earplugs gives us the beautiful tunes to the music that fire us up and make us passionate and to go the extra mile.

The history of Headphones:
The telephone earpiece such as the one pictured at the right was common at the beginning of the 20th century. Headphones originated from the earpiece, and were the only way to listen to audio signals before amplifiers were developed. The first truly successful set was developed byNathaniel Baldwin, who made them by hand in his kitchen and sold them to the U.S. Navy.
Very sensitive headphones such as those manufactured by Brandes around 1919 were commonly used for early radio work. These early headphones used moving iron drivers, either single ended or balanced armature. The requirement for high sensitivity meant no damping was used, thus the sound quality was crude. They also had very poor comfort compared to modern types, usually having no padding and too often having excessive clamping force to the head. Their impedance varied; headphones used in telegraph and telephone work had an impedance of 75 ohms. Those used with early wireless radio had to be more sensitive and were made with more turns of finer wire; impedance of 1,000 to 2,000 ohms was common, which suited both crystal sets and triode receivers.
In early powered radios, the headphone was part of the vacuum tube‘s plate circuit and had dangerous voltages on it. It was normally connected directly to the positive high voltage battery terminal, and the other battery terminal was securely earthed. The use of bare electrical connections meant that users could be shocked if they touched the bare headphone connections while adjusting an uncomfortable headset.
Let it fire you up:
Put on your headphones, go and take action, endure, become passionate, creative and help others do the same through your headphones!
