Grado SR325e

I inherited these from my Dad so they are special to me beyond their unique sound.
I like the old school look and that they are made in Brooklyn.
The soundstage sounds average to me for an open back, I feel the imaging may be better but that could be just that they are especially adept at pulling out detail in mids and highs. A cymbal splash is not just a "ting" but focused impact followed by the tone of the ringing. Ditto guitar strings.
Bass is there, impact of mid bass is great just not forward. Weak sub bass.
Everything it does is really good, it just does it its own way. The polar opposite of typical consumer headphones. Zero muddiness.
Yeah, the fit is not great. They just sort of hang off your head, resting against your ears but it's not uncomfortable particularly for me.
They are easily driven by anything but are best matched to a tube amp.
My LA Figaro 339 make these sing with detail expanding the soundstage increase the bass, making for a sound that rivals more expensive headphones.
Not perfect but very good for the money and different enough to make for a worthy addition to any music lover.

Sound signature : Bright, Clear, Aggressive, Detailed, Acoustic, Forward, Narrow
 
Comfort is not an issue if wear the right way - let the ear cup sits entirely ON the ear. It's an on ear headphone.
 
Good for : Rock, Acoustic, Lives, Vocals, Jazz and anything with real instruments.
Not so good for : Electronic, Pop, Hip hop, Rap and anything with synthetic sound.

First of all I like them so much that it is hard for me to be objective. But I’ll try.
 
sr325e are open “on the ear” dynamic headphones. Top of grado “prestige” line that includes 60, 80, 115, 225 and 325 models. “E” in the name means enhanced (if I’m not mistaken). The cable is very thick and the overall design looks a bit weird. They are handcrafted in brooklyn and the build quality is not always perfect.
 
The sound. The soundstage and separation is very good. On binaural recordings it is hard to believe that the musicians are not in your room. Seriously. The bass is nice, but not the best. The impact could be better. However it’s not bass that makes them special. It’s mids and highs. They are crystal clear, very upfront, crunchy and aggressive. That is what makes a “grado sound” that is usually either loved or hated. There are a lot of controversies in opinions. Some say that they are for rock only and not enjoyable with jazz or classics, some say that they are not good for electronic music. Some say that they are astonishingly good for everything you throw at them and I agree with this. There are some imperfections in sound (but these are not summit-fi headphones after all). However listening to rock sends shivers down my spine and I just can’t get used to it. They act as an arrogant and aggressive bandit but in a good way. If that makes any sense. The guitar riffs never sound like that (not even close) in any other headphones I tried. The jazz sounds amazing. The saxophone is just like never before.

sr325e are not neutral allrounders. They are just very special. I would recommend trying them for a number of tracks. Led Zeppelin, Guns and Roses, ACDC or anything similar would be a good showcase of what they can do to you. And then you may or may not like them. Actually the model doesn’t matter that much if you would like to understand what “grado sound” is. The signature will be the same even on sr60 that are sold for a fraction of the 325 price.
