You may have seen pictures of celebrities leaving the gym with a pair of these draped around their neck, or clutching theirs as they leave the recording studio. Dr Dre is an American rapper and record producer, and in July 2008 he launched Beats by Dre Dre headphones which have since gone on to be  huge success, counting Justin Bieber amongst their fans. Beats come in a variety of colours and designs as can be seen below…
