... To put through all the bass-heavy headphones more emphasis on the actual sound. I find that these headphones have enough bass, packed with a very good sound. Bose is known per se for a very good sound and therefore puts more on value than on "Boom Boom Boom". The know especially the home theater owners from Bose that the brand more on other things sets its value, other manufacturers turn on the bass.
Therefore, I think it's more a matter of taste which headphones to buy for themselves. I opted for a crisp and subtle bass with much more natural sound and am therefore with these headphones more than satisfied. Also because noises are kept well away from the outside and I could fully turn up the headphones without it bothers my fellow passengers on the train / bus etc.
