Sound quality general comment
  • Original sound fidelity: S-
  • Recommendation: S-
  • Personal preference: S


The GRADO RS2e headphones have the energetic high frequency range typical of GRADO, making rock, pop and Jazz sound fun and dynamic.


The sound field is wide and three-dimensional, with a gorgeous, glossy sound that is highly immersive and makes music come alive and fresh.


There are some parts that have a strong sense of extrusion, and some parts that are loud and flashy, and the sound has its own quirks, but perhaps because of the open-type design, it is not so tiring to listen to.


If you want to enjoy electric guitars in an upbeat atmosphere, this is a relatively recommended model in this price range. Personally, I like the sound of this model.

General comment

GRADO RS2e is a headphone that has a well-balanced sound with free sound field flatness in mind. These headphones have a wide sound field with a sense of depth and a glossy, lively, energetic sound that will make rock and pop music come alive and fun. It's no wonder they are considered the reference for GRADO sound.
