About the RS1
The Grado Reference Series RS1 headphones, introduced in the mid-1990s, mark the beginning of Grado's premium Reference line. Featuring handcrafted mahogany ear cups, a leather headband, and open-air design, they deliver an engaging sound with deep bass, luscious mids, and sparkling highs. Powered by 50mm dynamic drivers with neodymium magnets, copper voice coils, and vented diaphragms for low distortion and extended response, the RS1 offers a balanced, lively presentation ideal for audiophiles seeking warmth and presence. Variants like RS1e and later RS1x exist, but the original RS1 remains iconic. Weight is approximately 9 ounces (255g). Compatible with portable devices due to high efficiency, best with headphone amps.
