Summary: The Xb800 is a very punchy bass headphone. Compared to the previews XB line up i think that the 800s are between the xb500s and the xb700s since it's bass is punchy like the 500s but the 500s do have a lil bit more punchier bass, not too noticable but like the 700s the 800s goes lower than the 500s...
Conclusion: To be clear, Sony does make a wide variety of well-balanced headphones, suitable for a myriad of applications. And, though not our cup of tea, we can see why the Sony X might be popular with some listeners for its intense sound signature.
Pros: Flashy styling, Thunderous bass
Cons: Severe lack of balance, Anemic midrange and treble, Absent of detail or clarity
