Grado Signature S550
Grado Labs revealed the Signature S550, the latest addition to its growing Signature Line of open-back headphones and the fourth model in the series following the earlier S950 and S750 variants. Designed as a wood-housed dynamic headphone tuned for a warmer and more relaxed presentation than some traditional Grado designs, the S550 combines the company's 50 mm S2 driver platform with Brazilian walnut earcups and a modular cable architecture intended to support both desktop and portable listening systems.
