This is my 1st pair of Grados, so whether they have the "grado sound" of their headphones, I couldn't say. For my ears & taste of music (the majority of the time) This sound is very good. I listen to a mix of genres & styles: 60-80's classic rock, Jazz, Blues, Singers & Songwriters of any era/Folk, Classical and I really only listen to 90's-05' Alternative (Tool, Alice in Chains, Metallica, when I'm working out... which is often). For me, These are not good for Alt. When I want bass to pump & mids set back.
These are a MID CENTRIC sound signature.
Bass: Whether these have more bass than the original gr10's I don't know, but the bass on the E's is ample. It's not overbearing nor is it light. It's sufficient to fill in and work with the highs. It NEVER gets in the way of the mids, so no muddling. It reaches goes low when recording is low. I enjoy the bass quantity but I prefer a different bass quality. Meaning, it strives to go so low that it often doesn't keep it tight. Even though the upper bass never spreads into the lower mids, (because the separation of instruments is fantastic) the lower bass that it tries to reproduce will, at times, sound loose. Like a car sound system that tries to rattle the windows of all the cars around him, instead of keep it controlled within their own car. I don't prefer that kind of bass. I like tight, even if it means giving up some seriously low end overtures. For this reason I give the bass a 3. If you like loose bass then 4.
Pros: MIDS: To my ears, Forward by about 8 db. Great for singers & songwriters whose voice is the main instrument. Adele, Nora Jones, Bebel Gilberto, Dido, Eric Clapton, Nina Simone etc. ALL jazz, blues, folk, acoustic! Instrument seperation is really good. Soundstage however isn't very wide or deep. Perhaps I am in the first 5 rows & singer is dead center at 20ft in a bar setting. Cozy? I adapted to the mids quite well & even started to choose the gr10e's over other sound sig. Addicting sound
Cons: Highs: Some say they are sibilant or sparkle too much. I don't think either. I never experienced listening fatigue (2-3 hrs) and never found the cymbals or high hat crashes overbearing. To my ears maybe +6db.
FIT/COM: Here is my major letdown. Yes, They are comfortable w soft silicone & sit deep in the ear. If you don't intend to move around AT ALL they're fine, but You can NOT exercise, smile or sing along. Seal is broken VERY easy. Always adjusting b/c of loss of bass. Very Irritating
