I’ve given up trying to pick a favorite. The Hemps and GH-2 are just too good to decide between. So I’m just going to give my thoughts on the GH-2 using the Hemps as a comparison point.
A general description of the sound signature might be bright, mid-range focused, and good but rolled off bass.
In short, the GH-2 have more treble and upper mids, less lower mids and bass, more dynamics/impact in the upper range, less dynamics/impact in the lower range, wider soundstage, and better imaging when compared to the Hemps.
The treble is phenomenal, especially when combined with the mid-range. It is definitely bright, probably too bright for a lot of people, but it’s also very smooth and clean. It feels like there are no prominent peaks anywhere in the treble. Even with some of the most piercing treble sounds I can find in my library (ex: They Live ost: Sunglasses on) these never sound harsh or piercing. The only time they are ever too much is if the song has a lot of treble energy in general (like white noise or synth distortion) which can get pretty fatiguing at slightly higher volume. Otherwise I have nothing to complain about in the treble. It’s clean, detailed, and sounds great.
The mids are great as with all Grados. Like I mentioned, they mix very well with the treble to create a beautiful clear sound that feels so clean, detailed, and airy. Vocals are a high point imo. They cut through even in less vocal focused mixes like Rage Against The Machine and almost never sound shouty or harsh. Much like the treble, this only happens when it’s the song that is harsh or shouty. Both male and female vocals are great, but maybe with a bit of a bias for female. The lower half of the mids is much more “neutral” than something like the Hemps (which are ludicrously warm) but still maintain plenty enough warmth to not sound cold. Guitar, both acoustic and electric, are wonderful. Piano, strings, brass, everything orchestral, is all great. Possibly even the best I’ve ever heard. Metal and rock are still great, sounding as gritty or clean as needed. The Hemps might do this kind of thing a bit better, but the GH-2 are still exceptional in this regard. Electronic and synth based music is great. There is plenty of energy in the mids to make heavily distorted synth-wave sound visceral and exciting. Honestly I have literally nothing bad to say about the mids, so I’m going to move on before I ramble too much.
The upper bass is fairly good. It’s a bit light compared to the Hemps, but overall it’s more than adequate quantity wise. The real show is the quality. The bass is very tuneful (how distinguishable different bass frequencies sound) and detailed with plenty of texture. Bass guitar always sounds great. Bass drums still thud and kick well. It’s plenty detailed for lower synths and such to come across properly. The only real downside to the bass is that the sub-bass roles off. I wouldn’t say it’s too extreme, even when compared to other headphones like the HD58X and the like, but it is still enough to notice.
Technical performance like detail retrieval is quite good. I think maybe a bit better than the Hemps, but not quite as good as my Lawton modded X00s. The real stars are the dynamics, soundstage, and imaging. These can still literally tickle your ear just like the Hemps, but they do it best with the upper end of the frequency response while the Hemps are best in the lower half. Guitar and higher pitched percussion are properly physical at times, feeling like a vibrator on your ear. A great example of this is the beginning of Roll Right by Rage Against The Machine. Then there’s the soundstage and imaging. I haven’t properly A/B tested against my X00s, but the GH-2 are at least as good from what I remember. It tends to be wider than the Hemps but never looses intimacy. It’s also just as deep as the Hemp’s stage, if not deeper. The imaging is just as good as the stage. Instruments are placed perfectly and sounds can move in an almost uncanny way. Like I said, I haven’t properly A/B tested against my X00s, but I think the GH-2 might be better.
In conclusion, I feel the same about the GH-2 as I do about the Hemps. I love them now during the honeymoon stage and I will love them just as much a year from now. The Grado house sound is just my bread and butter it seems.
I don’t really have any specific music recommendations. The only genre that I feel these do particularly better than the others is orchestral, but I have yet to feel these sound anything less than great with any music.
I would like to thank @mochimashu for pointing this pair of GH-2 out on head-fi. Without you I would have never impulse baught these less than a month after impulse buying the Elegia.
Now I want more Grados. I think I have a problem.
Nevermind. Screw you mochimashu, you enabaler
