A:
Unfortunately to get the best possible sound, headphones need to be open-air. So, even being over the ear, the back of the diaphragm is open. There are many good closed or sealed phones out and a lot are decently priced. Sennheiser 203's come immediately to mind but all senn.s have 3 meter cords. Grado, Audio-Technica and others deserve a listen, personally, beats are over-priced and over-rated. The 518 Titans are not well suited for your needs, unless sound quality trumps all else.
