Bought the HD 550 with their own money after more than a decade with an HD 598 SE, and compared it with the HD 505 SE, HD 560S and HD 600 series. Finds it open, natural and balanced, with excellent imaging, air and comfort for both music and gaming, though vocals sit further back than on older Sennheisers; scores it 8.5/10.
“Bass has enough presence to give music some weight. Vocals are clear without being pushed into my face. Treble has detail and air without constantly trying to get my attention.”
