Grado S550 Signature Headphones

The Grado S550 Signature Headphones are open-back dynamic headphones built around matched 50 mm S2 drivers to deliver a warm, balanced acoustic response across an expansive 6 Hz to 44 kHz frequency range.

Natural Acoustic Resonance:

Solid Brazilian walnut wood housings encase the acoustic chambers, controlling unwanted internal vibrations and dampening physical resonance. This dense hardwood gives bass notes a rich, grounded presence while letting midrange instruments and vocals breathe with natural, organic timbre.

Expansive Open-Air Soundstage:

An open-back design allows soundwaves to radiate freely into the room rather than bouncing back into your ears. This open architecture creates a spacious, three-dimensional soundstage where instruments occupy distinct positions, reproducing the natural atmosphere of a live performance.

Comfort-Focused Brooklyn Craftsmanship:

Handcrafted in Brooklyn, the headphone chassis features a cushioned, adjustable headband that distributes weight evenly across your head to eliminate pressure points. Paired with breathable B cushions, the lightweight design ensures extended listening sessions remain comfortable and free from listener fatigue.
