... -Final Impressions-

If you enjoy headphones with a robust low end, bell-like clarity up top, with an expansive soundstage, and musicality for days, the TH-600 will serve you incredibly well. The TH-600 brings a powerful, immediate, authoritative sound, with a mature, commanding presence.

Sound Rating: Fantastic
