I'm not a wood expert so it's hard to judge it, but if I'm just going off looks it's breathtaking. The color is deep, rich, and cool-toned–very much a walnut wood. Weighing in at 395 grams, it's lightweight yet durable, ensuring a comfortable fit and reduced fatigue. Because Grado handcrafts each of its headphones, no two wood housings are the same. The wood grain on each headphone is never identical which is something truly special. Compared to the HP100 SE's aluminum housing, the sonic results of Brazilian Walnut were very clear.

Moving beyond the housing, the Signature S950 comes with two Grado ear pad cushions, G Cushions and F Cushions. The G cushions are more enveloping and are what I used most when listening. If you have larger ears or don't like the full coverage of the G cushions, the F cushions are wider on the inside and have a lower profile. Both the Signature S950 and HP100 SE feature a new headband assembly specifically designed for long listening sessions. The updated headband includes 50% more padding than earlier Grado models with a stainless steel band and adjustable height rods. Arguably the most exciting thing about the Signature S950 is the detachable headphone cable! The included cable features a 6.35mm connection but Grado has teased the possibility of alternative connection options with an adapter being available in the future, perhaps similar to how they've expanded connectivity for models like the SR60x and SR80x. It's something from Grado that I thought we'd never see, but it unlocks a world of upgradability.
