Review, and Personal Thoughts
Initial First Thoughts Prior to Use:
Those look painful to wear.
Initial First Impressions of Use:
I had Shure E2Cs back in the day, and what I can remember they don’t even compete. With my current Bose IE2s it has made me regret that I have even bought them in the first place.
My box, as we all know, came with the MKII sticker. If my understanding is right these are a build off the MKII, and the GR07 Classics are also supposedly to replace the MKIIs also. I may have misunderstood from what I have read around here though. The box did come with 3 Sony Hybrid style tips (XS, S, M: I verified these at the Yodobashi denki store with the actual hybrid tips), a double flange set, and a pair of grey Comply style M sized tip. Last two things included were the ear rubber wraps, and the User’s Mamual. Yeah I know its manual, but mamual gave it a nice lovable humor to it that it sticks now.
The card itself stats this about the IEMs:

- Cable: 1.30m TPU Cable Maximum 82 core 99.9999 Single Shielded Copper Wire ±3%
When I opened up the package I was like these IEMs look quite nice. I ordered the blue GR07 classics (GR07C). I was hesitant with ordering them in that color, and that is all they had at the time. I didn’t feel like taking the chance in waiting for the the wine or silver with 14 hour flights coming up. The color blue is actually a lot nicer in person than what the photos make it out to be, and very complimenting. I am quite pleased with color choice. I will be honest that I would much have rather of had them in black, and/or the Wine Red. Sadly black is not in option for the GR07C.
Now as for the build quality of the GR07C I can not compare them to its predecessors. What I can say it is very solid. Just by looking at it alone you can see that the build is of high quality. As well they appear to have gone through many quality assurance checks.
When looking at as many pictures as possible of the GR07s, MKII, & Bass Editions to compare with I have noticed that some of the pictures have shown some glue residue (I cannot say if this is from original manufacture or not, but it is all I have to base on). My current pair, and only pair ever of VSonic’s in general, I did not see or found any sort build flaws. This is quite assuring of the quality the brand puts into their products.
The housing design was of my most concern in choosing GR07C. I will not lie and say at first look I thought they seemed comfortable, cause they sure do not. The square design, and the initial positioning of the GR07C just looks painful. Again I was proven wrong by VSonic. Which is good cause comfort level is where I make the true decision if you stay in, or else be placed in the box again.
The first two days of wear (note: I wear headphones of all types for about an average of 10 hours a day.) gave slight sourness to the in lower back of the ear. How the housing rests on the inside one of the corners laid in that position, causing a slight sourness. This sourness was only felt upon removal or placement. I never once got the urge to have to remove due to tiredness, or sourness.
The design is the only thing I got an issue with. Since I did not any extreme discomfort, lasting sourness, or urge to remove I feel I have been muted. I still think the design could be more ear friendly, but I will let it go this time. On a good note these things are good to fall sleep with.
Setup: iPhone 4S>FiiO E11>GR07C
I was amazed by how clear the sounds was all around. The lows were deep, full, and natural. Best of all they did not overtake on the Mids or Highs. The highs were clear with a slight sharpness to them. I found this only to be the case with certain genres of music (i.e.. Electronica, some Rock, and/or Experimental). Mids were clear, smooth, and warm in delivering.
Sharpness in Highs have slightly dissipated.
I cannot say if this is due to burn-in, or not. I do know for a fact that burn-in exists, but improving sound quality? I find this to be a very debatable subject. Even if proof warrants it.
Approximate of 100 Hours (±3 hours) of Use:
As time went by I can say I did notice increase in clarity, and sound quality. I am not talking major, but definitely noticeable. I will say this is for sure the sharpness in the highs did clear out for me, and as time went by I noticed new sounds in the music I was listening to. Since I listen to a lot of indie music I have been able to tell if the recording quality of the music even more so. Again I will not say this is due to burn-in.
When I compared this to my Bose IE2, which I instantly retired upon seconds of listening, I can safely say I have gone to audio heaven. The Sound clarity and quality surpassed the Bose IE2s in every aspect, and now I really would like to compare them the Shure SE215s. Would love to compare the GR07C with its previous models, but lets not get to crazy.
Simply one of the best suggestions I have ever followed. As well one of the brands I will recommend from time to come.
I did not touch base on isolation for this reason: isolation varies between user, insert tips, and surroundings. In my honest opinion Comply’s give the best isolation, but that is just my opinion. Everyone has their own preference to how they want to isolate, and I feel that should be upon the user to decide how they feel about the isolation. Not the reviewer.
Were do I go from here:
iPhone 4s>JDS Labs oDAC>FiiO E11>GR07C maybe.
