I'll be getting the MH1 and MH1C soon, so I'll try that.

 

I use the included Vsonic bi-flange tips, and I always set the nozzle to forward-down, or forward-up (forward as in over-ear stance, forward from your face), then insert them as deep as I can.  For me this achieves the best sound.

 


 

In other news, I finally may have heard a tiny result from burn-in now.  I've played harsh electronic music (pretty much static, noise, sawtooth waves etc.) with bass on repeat, at very high volume (higher than 120dB) for around 10 hours twice. 

 

 

All of a sudden today, it seems like the GR07 MK2 is more articulate, it has a little more authority?

 

However, an issue is I may have just burned in my latest amplifier (iBasso P4 Warbler) in this process, and not the Vsonic at all?  Lol.

 

Another issue, when you wake up after a good sleep, music probably has more articulation and authority in it anyway, than when you crashed on the sofa after 7 hours of listening the night before.

 

 

Hmmm okay, I just connected the Vsonic GR07 MK2 to my Xperia Ray, played my familiar music, and this IEM does seem to sound a little different now.

 

 

 

I'm not stating this as fact, I'll leave it at current perception, but this IEM now sounds less 'boring', and the tonal colour has shifted a lot closer to the sound of an Aluminium driver.

 

I don't know, perhaps the violent burn-in resulted in myriads of nano fractures, creating a 'cleaner' driver surface, so it now has more of a bell-like effect to every impulse?

My hypothesis.

 

Tonal colour is a result of attack, decay, sustain and release.

 

 

 

Violent burn-in on the GR07 MK2 caused nano decrystallization.

 

An idea...

 

400

 

 

 

This sped up the attack angle, and extended the release, resulting in a more metallic sound colour.

 

The GR07 MK2 thus becomes perceptively 'clearer', and a tiny bit faster.

 

 

However, the difference is slight, and the overall colour is still quite pale, it's not a raven of sound, just a very, very nice... seagull.

 

 

It's not digital sounding like the ER-4, and can express some emotion, however it just lacks a lot of 'silver' and dazzle, it needs a strike of neon blue to become a more effervescent IEM.

 

It's not easy to fault it, but it hardly ever reaches higher than 7/10 in any sonic quality.  The alternatives, like the Sony EX600, have more deviant results, and a sharper ~6-7kHz spike, however the EX600 is just the more inviting IEM with more quality, like newly cut grass.

 

Similarly, a musical TWFK IEM like the UE700 is faster, has the needed shades of blue, and they're more rivetting.

 

 

I really tried to like the GR07 MK2, and I do in several ways, it's a very, very... average performer.  Like a track and field athlete that is just pretty decent at everything, yet excels at... nothing...

 

...except for versatility...

 

...and tonal intactness.

 

 

So in essence, when you look at the classy, supple cable, the very nice swivelling nozzle, the understated black cube that fits nicely into your ear, the decent construction quality, the included tips, and the price, it's a very, very decent IEM.

 

 

Interestingly, so is the Vsonic R04.

 

 

So really, I'd rather have the Vsonic R04 (I haven't heard the GR06) as a very decent 6.5/10 IEM, and then venture directly into the 9/10 IEM sonic gemstones out there, instead of investing into the GR07 MK2, if money is a concern.

 

Unless... I just wanted a nice, useful, understated, reference, pretty high-rez, safe IEM that doesn't push any limits, and will present you the sound quite faithfully.

 

 

Unless 2... I had an affinity for dynamic driver IEM's and I wanted the 'very best' of non-metallic drivers, at a junction of sound between metal and non-metal.

 

...on second thought I think Sony has already 'moved on' from bio-cellulose for a reason, and found higher quality sound in Polyimide, Vectran, etc.

 

 

With all cards dealt, I honestly prefer the Sony EX700 to the GR07 MK2.

 

 

The EX600 has two annoying qualities in it...

 

1 - No inner-soundspace (too spacious sounding, like trying to mimic a full-size headphone)

 

2 - Not transparent enough (it sounds very nice but it sounds too similar from source to source)

 

 

I've only heard the EX800ST (a.k.a. MDR-7550) and EX1000 very quickly, however from what I heard they both had slightly (yet still flawed) soundspace, and they are most likely more transparent.

 

The GR07 MK2 doesn't have the annoying soundspace issue, it's not very transparent though, I'd say equal to the EX600.

 

 

Why am I talking about Sony so much?  The EX600 and GR07 have been rivals for a long time now, they're both great dynamic drivers at a similar price.

 

The only other earphone to ever use bio-cellulose was... the Sony MDR-E888.  I once loved the E888, it's quite special.  After the flooding in Thailand Sony discontinued it after more than 10 years on the market!

 

The Vsonic is not the MDR-E888 in an IEM.  They sound too different, and the E888 was very fragile, the diaphragm could break, while in the GR07 I can blast noise and bass at over 120dB without issue.

 

So honestly, I think Vsonic 'cheated', it's a bio-cellulose layer on another layer, and they may have skipped some of the strict processes required to get the most acoustically out of bio-cellulose material.

 

The Vsonic sounds closer to the Denon Dx000 headphones than the E888, so something is iffy there.

 

 

In some ways, the Vsonic R04 reminded me of a Sony as well, I wonder if a Sony factory in China once taught a lot of apprentices how to make their products, then they eventually left and founded Vsonic!

 

 

I will say however that Vsonic offer excellent price to performance ratio in all their products and attention to detail, they are a real player in the IEM scene.

 

 

So here is a break-down of sonic traits in the GR07 MK2.

 

 

bass ---- The bass quality is good, the GR07 has a very unusual quality of warmth and snappiness at the same time.  I once said in some electronic music, the notes retract like a lizard tongue, it's the only truly exciting feature I ever experienced in the GR07 MK2.

 

The sub-bass is nice and extended and has very good volume, the SPL down there is 'just right', in my view, I've never once considered using an equalizer on any bass lines.

 

 

mids ---- The mids are tonally intact and once more have near-perfect SPL, if you want a vocal monitoring IEM though this isn't it, vocals have no special shimmer or sultriness, all you find is a white / hazel documentary of sound with pleasingly high resolution.

 

 

highs ---- Here once more, Vsonic have crafted the SPL so it's detailed and yet not offensive, there is no hardness, no glare, no sibilance (not quite), and it presents you a little more detail in the highs than usual.  You can safely increase the volume without turning violins into glass, unlike in the Sony EX series.

 

So IEM deserves an accolade for the 'reference' level sound in this IEM.

 

higher-highs ---- The Vsonic R04 had more extension so this is not very impressive.  This IEM doesn't give you ER-4 or TF10 high-highs.  There are no sizzling spikes at 12kHz or anything like that, most likely the extension hits a wall and falls into a valley around 14kHz, I can't really tell if it's a lack of highs or if it's a dissonance.

 

You can correct the dissonance in this IEM by adjusting the nozzles to forward-down or forward-up, then it becomes a little more transparent, though still not perfect.

 

 

soundspace ---- The GR07 MK2 soundspace is just right, it has inner-core, mid-core and sufficient outer-core.  Imagine soundspace (soundstage, whatever) like an onion.  Now imagine the layers of the onion.

 

The width and height seem fine, the 'back' isn't really there but it hardly ever is.  Deep insertion really helps a little as usual, try the nozzle forward-down, then insert deeper.

 

 

layering ---- The GR07 MK2 is pretty weak in layering, 6/10.  (this is how distinct the layers in the onion are and how they move)

 

 

imaging ---- The GR07 MK2 is pretty decent in imaging, it's not hazy or fuzzy at all, it's sharp though not like a needle or laser, that's usually reserved for balanced-armatures.  As a dynamic driver, it's pretty nice here.  You never get a feeling of excitement in the imaging, it's just decent, nice 1.

 

 

resolution ---- The resolution is high, acoustics and classical instruments are nice.  Not as high as the Audio Technica CKW1000ANV though, and not the Sony EX700 either.

 

 

Tonal colour ---- Hazel / white, fairly warm, leaning towards metallic... Aluminium.  I believe violent burn-in will change the ASDR envelope, it sounds like a bell made out of... I don't know, straw.

 

It is not tonally flat like some balanced-armature IEM's, The MK2 has nice sight into the music, it's a joy, just not a jade or sapphire.

 

 

In essence, the R07 is too much of this...

 

1000

 

 

Not enough of this...

 

1000

 

 

 

Music synergy --- It seems to fit like a glove with... a shovel.  The Vsonic GR07 MK2 is an athlete average at everything.  Except I value it with pure acoustic recordings, classical music, and some fast electronic music the most.

 

 

(I can't believe it my Internet Explorer crashed and I lost half the review !)

 

I'll take some pics later.

 

 

Thank you very much Vsonic for making this very excellent... very average IEM!!

”The Perfect Average”

Nice review kiteki! Many people were waiting for more details from you.

However, if one were to look at the individual aspects of your review it would seem to add up to a higher score imo. Good bass, mids, treble, imaging, resolution and tonally accurate for the most part... Those are all very rare for one iem to have ime.

I do agree about the highest highs falling short, resulting in less air then most BA's.

I have two questions: What is the difference between imaging and layering?

And: Would you extrapolate a bit more on the mkII's tonal balance? You seem on the fence.

I'm happy to answer any questions, as soon as I have time (at the office now).

 

 

Yes the Vsonic is above average in a lot of categories, so many in fact that it's a Jack of all trades, yet a master of none.

 

It is perhaps the only IEM which truly is this, thusly it's "the perfect average".

 

There are more categories to cover, I lost half the review.

 

 

I'll expound on the difference between imaging and layering later.  I'll draw a picture if I have time.

post #711 of 981

Manufacturers recommended burn in for the GR07 is 200-300 hours. I have had mine a while now and can definitely say the sound of them have changed over time. The harshness and sibilance that appears out of the box has totally gone, and they are now one of my very favourite IEM's. I would phrase Kiteki's "jack of all trades, master of none", as "suits everything you throw at it".

 

I don't have the broad experience that Kiteki has, but I am struggling to think of another IEM that is more accomplished than this one, at its price point.

Yep, that about says it all right there, exactly. That part of the review really sunk in. Take note kiddies. smile.gif

Only it takes hearing the second picture to understand why the first is so relevant.
post #714 of 981

The GR07 is near perfect to me because it simply removes itself from the equation and lets all the different genres of music sound good at the very least. I've really never heard the GR07 sound bad at anything, unlike several other iems I've tried.

I quite agree.

 

I have ordered the T-Peos H100 Hybrid today to see how that sounds, as people have been raving about it on these forums, and in particular, H2OFidelity loves it and I often find my tastes seem to coincide with his, and he prefers it to the GR07, so I shall be interested to see how it compares. It is also priced the same as the GR07 from a UK perspective, so therefore has to be viewed as a competitor. I am also ordering a 75 Ohm adaptor (the one that people usually use to turn an Ety ER4P into a ER4S), for trying with the H100, as I have seen some reports of it improving the H100 still further.

I actually own those: http://www.head-fi.org/t/630235/t-peos-h-100-hybrid-iem-appreciation-thread/675#post_8867027 and http://www.head-fi.org/t/630235/t-peos-h-100-hybrid-iem-appreciation-thread/750#post_8876371

 

I recently put them on a loaner tour, and would have included you if I had known you were interested.

 

Either way, I look forward to your impressions.

The cheaper TWFK IEM's ($150 or less) come to mind, perhaps Etymotic HF5 with a 75 ohm resistor too, except they're not dynamic drivers.  Then perhaps JVC FXD80 if you like V-shaped (hip-hop, action movies, etc.).

 

My view is... if I could know what I know today, let's say 1.5 years ago, and just wanted to enjoy music (not explore audio, which is different) with high quality dynamic driver IEM's, I think I'd invest first in the Vsonic GR04 (updated version), then second in the CKW1000ANV when I was ready.  They seem like the ideal two IEM's to me, from what I know today.

 

(as such, in that specific view, the GR07 falls into a value void)

The Sony EX600 wins in the high-highs.

 

 


 

In other news my Sony / Ericsson MH1 and MH1C arrived today........................................

 

 

I just ordered the Hifiman RE262 for $99, black friday special price!  The RE272 for $199 is definitely worth considering too I think.

 

 

All I can say right now is the RE272 is like 10 zillion times better than the MH1.  I sortof actually feel had.

How do you define the "better".

Also, though you are not yet settled on it, let us (or at least me) know how they compare after burn in will you?

the re 272s are simply 'better' ... there's no real need to define better here ... and in case you feel the need, take a listen and define it your self ..

 

incase you want a hand at it ..

Kiteki!! the wait was worth it!

 

Brilliant review there ... !

 

Now the GH-ERC-DMS awaits your impressions.. rolleyes.gif
