What reviewers said
Grado RS1
The Grado RS1 is a premium open-back headphone known for its warm, organic midrange and lively, engaging sound that prioritizes musical enjoyment over clinical analysis. Handcrafted wooden housings and a lightweight build contribute to its premium feel, though its open-back nature means significant sound leakage. While it excels with most genres, its forward presentation can be less ideal for classical or chamber music, and comfort and ergonomics are somewhat polarizing.
- Pro:Lush, organic midrange with natural timbre
- Pro:Engaging, lively presentation that makes music enjoyable
- Pro:Lightweight and comfortable for extended listening
- Con:Open-back design leaks sound significantly
- Con:Forward presentation may not suit classical or chamber music
- Con:Comfort and fit can vary depending on ear placement
