The best briefcase I have ever owned – it has literally been around the world with me – is my Tumi leather soft-side, expandable briefcase. I still own it and whenever I go anywhere for a business meeting…it goes with me. So it caught my attention today scanning the news wire services when I saw a press release that Monster (formerly Monster Cable) was partnering with Tumi to launch a new headphone – called the Tumi x Monster – based on their existing Inspirations model.
