Mine arrived a couple days ago from Lend Me Ur Ears. Mine DID have the proper "GR07 Classic" stickers, and the same accessories as others have posted. (S, M, L, double flange, and Comply eartips, in addition to the ear hooks)
I decided to wait a bit to listen and post some impressions so far. My total use is easily under 100 hours.
So far, testing with various music, I can say that these are very impressive.
A small sample of the tracks used: (As you can see, quite a few different genres!)
"Rolling in the Deep" - The Piano Guys
"Radars Over The Ghosts Of Chernobyl" - Lights Out Asia
"Breathe" - Alexi Murdoch
"Piercing the Sky" -
Magnus Pålsson
"The Safety Dance" - Men Without Hats
"Bohemian Rhapsody" - Queen
"This Cowboy's Hat" - Chris LeDoux
Bass:
It has quite a bit of "power" to it, but it does stay remarkably controlled. It's a touch punchy like BA bass, but it always has a feeling of authority. They do not, however, feel boosted in the low end unlike my Denon AH-C300 (not surprising, as they are VERY different 'phones) They maintain this power, even at their lowest reaches.
Mids:
The ids are quite detailed. I would not call it "rich" or any such term, as it sounds much like a BA: Quite quick and lean. Though, unlike my BA 'phones, it does sound a bit smoother, which makes it a touch more relaxing. Vocals sound "just right" to my ear.
Highs:
This is where a slight issue comes in: The lower highs are a bit boosted, resulting in some "detail" but more often it becomes sibilant in some tracks. Not a surprise, as it's been noted before, but still a little bit unpleasant. The rest of the highs are very good. It isn't all too "fun," but it is very neutral, which I actually do find fun. They are quite detailed, and revealing, but not ruthlessly so. You can happily listen to most things, but these WILL exasperate any sibilance, if present.
They also extend quite a ways, instead of being... faded off? (I can't remember the term) I like this.
Overall thoughts:
They are very neutral, and have a rather spacious soundstage. They're much warmer than what I'm used to (BA headphones such as the HF5 and R-50, so that's ok) They are not QUITE as detailed as the BA 'phones, but they come VERY close. They do have more bass and sub-bass presence, though they remain controlled and detailed. The mids are again detailed and controlled.
Nothing really stands out on these, so they don't specialise in any specific genre of music. That's perfect IMO, as they sound great for everything I've thrown at them. If you're a fan of neutral headphones, for $100, they're really good. I'd suggest picking a pair up.
