Welcome to EKKO-the ultimate in wireless translation devices which is able to translate over 180 languages and accents including the frequently omitted Tagalog, Bisaya, and Ilocano. The device is reminiscent of the traditional hands free telephone headset created in the late 19th century and used by telephone switchboard operators from the 1960s and 1970s the company Koss dominated the music headphone industry in the U.S. by adapting the device to radios and stereos. At this time the famous rock group, The Beatles, were gaining popularity so Koss created and endorsed a signature headphone with the Beatles custom sticker on it. In the 1980s these headphones had on-ear pads that pressed against the ears rather than around them. These headphones were smaller and lighter than the circumaural (total ear coverage) design and prevented loss of signal strength which interfered with music clarity. A typical telecom headset consisted of a headphone and a microphone.
Further technology advancement showed how versatile the headphones were as they connected signal sources of audio amplifiers, improved radio designs, CD players, portable media players, mobile phones, video game consoles, and electronic music instruments. The connections were either direct-noted by the use of a cord or by using wireless technology such as Bluetooth, DECT, or FM radio.
