Even on the best of headphones, you are distracted by external sounds. This is becoming a bigger problem now that people are listening to music while taking a jog in the park, while travelling in public transport or even while working in office. All these are locations where there is a lot of ambient noise that affects the audio experience dramatically.

The sound blocking abilities also makes the CX 275s very loud, but not ear splittingly so. The audio quality is really good and lets you enjoy all types of music from high tempo Bollywood numbers to slow Carnatic classics. But this is not an audiophile headphone like the
