While I wouldn't categorize myself as a bass enthusiast, I do enjoy the deep bass response of the Sony IER-Z1R when I'm in the mood for it. In comparison, I find that the Sennheiser HD800S offers a more balanced overall sound. Headphones with a punchier bass, in my experience, tend to overshadow other elements of the audio spectrum. After recently listening to several tracks for comparison, I still believe the HD800S delivers superior overall sound qualityHow about the lack in bass
