Our take: In daily use the HD 800S feels like a precision instrument once paired with a good amp, revealing micro-details in classical recordings that the XM5 smooths over. The Sony folds flat into a bag and blocks subway noise instantly, but its closed cups create a more intimate and less airy presentation during long flights.
Focal Utopia surpasses the Sennheiser HD 800 S in transient speed and midrange clarity with its beryllium drivers. The HD 800 S counters with a wider soundstage suited to large-scale recordings.
