Hello all. I travel and work remotely quite often and listen to music--50% classical, 50% rock--out of my laptop, iPhone, iPod, and iPad. I am looking for suggestions on the best headphones, portable amps, and any anything else I might need to have a great sound experience while keeping everything portable. Typical uses would be in the airplane, at the airport, in a noisy coffee shop, or in a hotel room. Price is not the most significant concern.
