Michael Phelps has made his tendency to wear headphones before a game just as famous as his legendary career. The star was seen sporting different color headphones during the 2012 Olympics and fans on Twitter have taken notice. 

"@MichaelPhelps Which is bigger: your medal collection or yourheadphone collection?" @rabahkamal wrote on Twitter. 

"I swear Michael Phelps has a new headphone every race," @lilysteph_ shared.

Michael Phelps chose wisely in which headphones to rock out to before earning a myriad of golds. The swimmer's stylish audio gear are Sol Republic's Tracks. 

The Wilsonville-based headphones company have produced colorful and sleek headsets that are difficult not to notice.  However, what makes the magical ear speakers is their quality in providing stability, as they are very flexible. 

Amazingly, you can also switch out the colors on them as well.  Hence, the headphones alone are what put out the actual audio sound.

The Sol Republic Tracks and Tracks HD over-earphones are said to sell for $99 to $129.

Michael Phelps' medal count hit 22 on Saturday when he swam his last in his professional career. He closed out his fourth and final Olympic games as the most decorated Olympian in Olympic Games history.
