Overview

Engineered with 50mm dynamic drivers and open air cups, these 335g headphones deliver a 6Hz to 44kHz frequency range. Detachable silver cables with 4 pin mini XLR jacks ensure simple integration into any high end sound system setup.

Grado Signature S550s are headphones with 50mm dynamic drivers and an open air cup design. The frequency response is full, extending from 6Hz to 44kHz. THD is less than 0.2% at 100dB and the driver pairs are matched to within 0.05dB to maintain a sharp and accurate stereo image. They have a relatively easy to drive 38ohm nominal impedance and 112dB sensitivity so are equally at home with a dedicated desk amp as they are in a typical listening setup.

A detachable Signature Silver cable connects to each earcup via secure 4 pin mini XLR jacks. The source end has a standard 3.5mm plug and includes a screw on 6.3mm adapter for use with home stereo. The cable has a soft flexible jacket which prevents the line from kinking and thus protects the internal conductors over time. Swapping cables or adjusting length is very easy in any system setup.

335g adjustable metal headband to spread the clamping force evenly and avoid any hot spots on the head during long listening sessions. The stock B ear cushions are pre fitted to give a neutral acoustic response, the earcups are also capable of taking the optional S, F, L or G earcups should you wish to have a different feel or a wider soundstage.
