Verdict

The Grado RS1i is a premium open-back, supra-aural (on-ear) headphone featuring handcrafted mahogany wood enclosures and air chambers designed to eliminate resonance for a warm, natural tonal quality. Technically, it utilizes 40mm vented dynamic drivers precisely matched to within 0.05dB, an ultra-high purity long-crystal copper (UHPLC) voice coil, and a sturdy 8-conductor connecting cable to deliver a wide frequency response of 12Hz–30kHz with 32-ohm impedance and 98dB sensitivity. Its main characteristics include an expansive soundstage with detailed stereo imaging and a signature 'forward' midrange that excels in bringing vocals and acoustic instruments to life with rhythmic excitement. Key pros are its lightweight 9oz (255g) design, high efficiency making it extremely easy to drive without a dedicated amplifier, and a smooth, transparent high-end that provides great musical definition. Notable cons include subpar long-term comfort due to the scratchy texture of the stock L-cushion foam pads, a non-detachable and cumbersome cable, and an aggressive upper-midrange peak that can occasionally sound sibilant or 'shouty' on certain recordings.
