Ghanaian-British engineer and technology entrepreneur, Danny Manu, has invented the world's first wireless headphones capable of instantly translating up to 40 languages in high-definition. The headphones are called "Click", use Bluetooth technology for language detection, and work by pairing with a smartphone.

On the other hand, they allow users to call, text, and read notifications from their devices. With the device it is possible to translate voice to text and text to voice.

The headsets learn the language spoken, and each user can communicate with almost two billion people around the world.

Unlike similar inventions of the past, "Click" does not need the Internet to perform its auto-translation tasks.

The headphones by Danny Manu, founder of MyManu, are revolutionary in the world in that, through technology, they break down one of the most difficult barriers in human interaction, language.

The invention became a success in markets in Europe, the United States, and Asia.

It is another case of one who believes in his idea regardless of the setbacks.

"Like all other businesses run by ethnic minorities in the UK, I had difficulty getting the funding I needed," he recounted.

Danny Manu was born in the UK, however his parents are Ghanaian. He studied at Oxford Brookes University and worked at Quanta Networks Inc. and MEDYBIRD before founding MyManu in 2014. He was recently recognized by Google for his contributions to science, art and culture.
