Beware the "REPS" / Fakes.
What I found, when I did a cross country trip on my BMW GS,-- use the FOAM TIPS for maximum noise isolation. (I used Shures back then)
Also, not sure how much you 'vote' with your wallet, but google "monster cable lawsuits bullies". In short, they sue anyone with "Monster" in their name. From Auto Repair shops, to websites.
However, there is no question the MDTs and even the Monster Dr. Dre Beats are excellent products.
