Independent shopping perspective
HD 550 is an open-back, over-ear design for listening at home, gaming, and home entertainment. Its angled 150-ohm dynamic transducers are designed to present depth and position in the soundstage, while the 6Hz–39.5kHz response covers a wide frequency range. At 237 grams, with reduced clamping force, soft ear-cup cushioning, and a padded synthetic-leather headband, it is built for extended sessions. The detachable cable and replaceable HD 500 series-compatible parts make ongoing maintenance more straightforward.
