Sony MDR XB250 is the entry level extra bass headphones from Sony and doesn’t quite pack the punchy essence of the XB series. It for sure has some bass but other frequencies are not at all emphasized. In fact the low end is also muddy. It even sound some what dull and the maximum loudness is also very low. These are On the Ear headphones and aren’t quite good in isolating noise. The ear padding is also very minimal so these aren’t quite comfortable for long duration use.
