Finally did a full comparison of all of my Grado headphones. Maybe it's helpful to someone torturing his brain about what Grado to buy next
I tested all headphones with a Mojo 2, EQ set to neutral. I don't care much about sound stage so i didn't say anything about it. For me they all sound great in that regard anyway.
GH2
- Very balanced across the frequency range
- Doesn't need EQ, works very well with every source i tried it with, even the iPad headphone jack
- No real sub bass, lower bass slightly bloated, otherwise punchy
- Ok mids
- Clear nice treble but not sibilant
- The sound has a certain je ne sais quois mojo, my girl friend loves it and so do i
GS1000i
- On the muffled side
- Massive yet bloated bass and sub bass
- Very nice mids
- Low treble ok, high treble muffled
- Probably needs some EQ but the Mojo EQ doesn't help much
- Great for music with not much low bass and high treble, then it sounds very nice and serious
PS500e
- Very balanced across the frequency range similar to the GH2 but more neutral
- Every frequency band is there, no need for EQ, because of that it sounds well-rounded or some might say "boring"
- Works well with every sound source
- Sounds like a real Grado but without the "downsides"
RS1 button ("Classic", not sure if A, B or C, used with F pads, too sibilant with L pads)
- Similar to GS1000i but less bassy and even less treble, overall a little more well-rounded
- Bass strong but slightly bloated
- Very nice mids, brings out stuff in guitar solos i hadn't heard before
- Great with a 0 0 +5 +5 treble boost from the Mojo EQ as there is nearly no high treble
RS2e
- Awesome with some EQ
- Very lean bass but surprisinlgy there is some sub bass
- Pretty, non-sibilant treble
- Ok mids
- Needs a +5 +5 0 0 EQ bass boost which sounds awesome. Very nice defined punchy bass with that setting, the treble is great anyway
- Without the Mojo 2 EQ it always lacked something for me but with EQ it's da bomb!
SR325e
- Similar to RS2, great with some EQ
- Lean sub bass, bass and mids (but more bass than the RS2e)
- Very good treble and extraordinary high treble (aka "Grado magic") which none of the others has!
- The treble is why you must keep this headphone, great to spot new nuances in guitars!
- Set EQ to +4 +4 0 0 so you get a nice bass-ment under that great treble
WH1
- Weird bell-shaped frequency range
- Sounds like a vintage radio which can work well for some kinds of music (Beatles, classic, singing, jazz)
- Very good mids, beautiful for voices
- EQ didn't really help with the shortcomings
tl;dr
GH2
Buy, you can't go wrong with it.
GS1000i
Interesting, different, beautifully made, not a must have for me
PS500e
Buy, you can't go wrong with it.
RS1 button
I like it because it uses F pads and is vintage but honestly it sounds weird
RS2e
Buy if you got EQ or bassy amp
SR325e
Buy for the treble, it's cheap!
WH1
Still trying to find a reason why i need it, but it's pretty and special
BTW, I will keep all of those 7, i probably got every Grado sound flavour i need with them.
