WORLD-CLASS PERFORMANCE AND SUPERIOR COMFORT FROM HEADPHONES DESIGNED TO BRING YOU CLOSER TO THE MUSIC YOU LOVE. You'd want to pick these Sony headphones over the Bose because not only do they provide the same level of awesome noise-cancellation, but they have three neat tricks that Bose just doesn't have on its headphones: One is an ambient noise mode that only lets in mid-to-high frequency tones (announcements over a loudspeaker, for instance) and another being Quick Attention mode that allows you to let in all outside noise without taking off the headphones.
The requirement for high sensitivity meant that no damping was used, so the frequency response of the diaphragm had large peaks due to resonance, resulting in poor sound quality These early models lacked padding, and were often uncomfortable to wear for long periods. Typical closed-back headphones block 8 to 12 dB, and in-ears anywhere from 10 to 15 dB. Some models have been specifically designed for drummers to facilitate the drummer monitoring the recorded sound while reducing sound directly from the drums as much as possible. High-quality headphones can have an extremely flat low-frequency response down to 20 Hz within 3 dB. While a loudspeaker must use a relatively large (often 15" or 18") speaker driver to reproduce low frequencies, headphones can accurately reproduce bass and sub-bass frequencies with speaker drivers only 40-50 millimeters wide (or much smaller, as is the case with in-ear monitor headphones). http://www.headphonenow.com/
