VSONIC GR07

Posted

Pros: Very well balanced and very precise sound, no major flaws, adjustable nozzle angle

Cons: Slightly springy cable, over-the-ear only, sibilant/presence boosted with certain tips, slightly warm, could have more highest end

VSonic GR07 is a great example of IEM strong because it has few flaws and almost all of these are possible to correct with a good equalizer.

Bass is perfectly controlled, excellent texture, very well extended (-6 dB at 30 Hz with perfect seal), perhaps a bit warm due to high-bass boost (~250 Hz). No bass bleed is present.

Mids can be slightly forward to slightly laid back depending on tips and depth of fit.

Highs... here's the issue. With shallow insertion, there can be a fair amount of lower highs boost, around 6kHz, which combined with some highest end peaks can sound sibilant. Using foam tips helps with this, deep insertion completely removes this issue. GR07 don't have a lot of energy at the highest end, but they do have extension, so it can be corrected.

Timbre is excellent - delicate and unassuming, with excellent detailing, not overly aggresive and not overly smooth.

Soundstaging depends on depth of fit. With shallow fit, the soundstage isn't the widest, but is quite competent - with minor positioning issues due to sibilance and high-bass boost. With deep fit it is perfect, both width and depth, there's vertical resolution too - it will unfortunately make all recording and mixing flaws in this regard obvious.

Fit is excellent both for deep and shallow insertion due to rounded edges and no molding artifacts, small enough size and adjustable nozzle angle as well as a fairly large tip selection. GR07's nozzle is unusual sized though which limits possibilities. For Comply foams, T140 is the correct size.

Isolation is good for dynamic driver IEMs, microphonics are nonexistent.

Cable doesn't tolerate any kind of rotation around the axis of the cable for the part above Y split. If any is present, the cable tends to jump off the ear. This is easily remedied with the included ear guides or neck cable adjuster.

3.5mm L-shaped jack is iPhone friendly and seems very sturdy.

Build quality is very good with a minor exception - the strain reliefs tend to come apart from the body of the IEM. Easy to fix with a dot or two of superglue.

GR07 are efficient enough to be driven directly from a portable, do not gain a lot of quality when amplified.

 

Their main problem is availability - there are few sellers and those can be a bit remote.

 

--

Now that my RE272 cable broke, I'm stuck with these. They need somewhat extreme equalization to get rid of the presence boost, but with T200 Small, truly a winner.

Of course they're somewhat less analytical, slightly lowpassed (17.5kHz) but beautiful texture.

Without eq they are pretty harsh and "flat" sounding, as in no depth, likely due to presence boost.

Equalization lets them have great depth resolution too.

 

GR07 bass sure is fast and tight, but it has less natural decay than RE272's. Kind of like it's trimmed or slightly compressed. However, vocals are presented far more liquid and with better detailing, while higher end (presence) sounds a bit electric/harsh even after correction.

Pros: Highly detailed, neutral, goes well with whatever you throw at it

Cons: Can be sibilant (requires 100+ hours of burn in), springy cable, unhelpful strain reliefs.

These are amazing IEMs for the price. It is a balanced IEM and isnt lacking across the spectrum. They can handle pretty much every genre you put through these.

The bass on these is excellent, it rumbles down deep, while being very quick and tight. But the main thing which I love about the bass on these is the 'weight'. When the track calls for it these really do move a whole lot of air and slam it against your ear drums.

As for the midrage, I would say it is neutral, but on some tracks the mids are somewhat warm. With that said.. I'm not sure if the mids are actually warm, or the IEM is just neutral and reproducing warm mids...

The vocals on these are amazing as well. It is very intimate and sweet. These really do make vocals come alive and are also (very) forward (T.V. Carpio's cover of I Want to Hold Your Hand from the Across the Universe OST).

For the treble, I'd just like to say that it doesn't contain enough sparkle to satisfy any treblehead. Despite that, these still contain enough sparkle and detail to satisfy my needs.

Instrument separation on these are also great. I can just 'lock onto' an instrument and it seems like it's the only one playing. A funny remark made by a friend of mine (who is just your typical consumer) told me that he didn't like them because all the instruments playing is all "separated" and not "playing together". (I think he likes to have zero separation and to have a tiny soundstage) rolleyes.gif

The only con I can think of is the sibilance. Every lyric that has an 's', (and 'd' and 'th') on some recordings are unbearable. A good example of this would be the song Heartquake! by Sienna Skies.

The only remedy for this is to burn them in for 100 hours. After you hit that mark there may still be some sibilance but they will eventually be non-existant (I have put through around 450 hours through mine). wink_face.gif

 

I am VERY happy with my GR07s! ksc75smile.gif

 

Here's a list of some of the songs I used to test out my GR07s (all songs are lossless or high quality lossy MP3/AAC):

Perfect Future - Make Fun

Perfect Future - Colonization

Sienna Skies - Heartquake!
T.V. Carpio - I Want to Hold Your Hand [Across the Universe OST]

Joe Anderson & Salma Hayek - Happiness is a Warm Gun [Across the Universe OST]

Papa Roach - Getting Away With Murder

Versailles - Silent Knight

Uppermost - Born Limitless

Uppermost - Satellite

Morgan Page - The Longest Road (Deadmau5 Vocal Remix)

with some classical here and there.

Pros: fit, value

Cons: a little plain sounding

these are nicely made and sound nice. They definitely put their sound signature stamp all over my record collection which is odd because they are fairly neutral in many respects. I feel it's somewhere in the dynamics and/or presentation that they add their unwanted stamp. For their designed purpose, on stage, I say these are spectacular and well made, but for casual and relaxed listening, they did not excite me enough to warrant further listening. But definitely worth a try considering they are reasonable priced, and measure well. give 'em a go and see if the vsonic sound stamp is 'for you'

Pros: sound stage,

Cons: sibilance

they're pretty nice. does what I need them to do for a decent price. 

Posted

Pros: Wonderful bass, super transparent, good and accurate soundstage and detailed, adjustable-angle nozzle, couldnt be better build and p/p

Cons: harsh treble, lack of the hight-mids, a little uncomfortable to long-term wear(angular shape) , a little boring

Update on my 2nd time purchasing the GR07 in March 2013..

...more about the GR07: warm mids

IMHO:

Sound: 8/10 (compared to the best iems i have ever had was W4 and Ex1000 10/10)

p/p: 10/10

Posted

Pros: Great overall sound, HUGE bang for the buck, nice looking IEM, works well with most set ups

Cons: can be difficult to get an proper insertion (isolation)

For the price somewhere between $150.00 and $180.00 USD, there really isn't many other competition for the price. They really get the job done well. Can get a little stale in sound sometimes but that's really a rare case. These really are great!

 

Great sense if air in the treble (one of the best I've heard) with great detail and extension (sibilance was not a problem for me personally).

 

Fairly flat mid range that is true to the recording.

 

Very quick impact bass (especially for a dynamic driver) that's slightly north of neutral with great extension and accuracy.

 

Wide soundstage, lacking a bit in height and depth, but again with pretty accurate imaging.

 

Overall a great tonal balance and a very natural sound signature that is capable of handling most genres fairly well. Having that in mind plus being one of the most detailed iem in the price bracket (and honestly competing with iems hundreds of dollars greater in price), Vsonic has a winner here. Those looking for more low end have the option of the bass edition which is a great option to have.

Pros: not fatiguing at all, sounds great with just about anything, very very relaxing iems

Cons: dont like how you are supposed to wear the wire up and around the ear, and if you wear it straight down its kind of a weird fit.

just wonderful little iems. wish the isolation was a little better, not bad though, just nitpicking. The microphonics are unacceptable, just a light tap on the cable and i can hear it, annoying as crap, but definitely not a deal breaker.

Posted

Pros: Great bang for the buck value, balanced sound-signature, very wide sound-stage, good building quality, a lot of included accessories.

Cons: The isolation is only average.

Prior to the review, I would like to thank VSonic for the review sample.

 

VSonic is a Chinese IEM company. For years, they've been one of the leading OEM manufacturers in the world, manufacturing for some of the leading audio companies in the world. A few years ago, VSonic had started to develop IEMs to be sold under their own brand name. The flagship, the then called "R07" was developed for more than three years. Today, after its name had been changed to "GR07", I'll be reviewing it.

 

Before we start, here the technical specification of the VSonic GR07:

Driver Type: 11mm CCAW Dynamic w/ Multi-layers Bio-cellulose

Frequency Response: 7Hz-30 KHz

Sensitivity: 105dB

Impedance: 50Ω

Cable: 1.3m Silver cable

Connector: 3.5mm Gold-plated L-plug

 

img_2715.jpg?w=225&h=300

 

Packaging: The GR07 comes in a quite big fully transparent-plastic box, which the IEMs can be seen through, placed on a black velvet-like surface, in a very impressive way. After pulling the velvet surface off, there's a paper surface, which all of the accessories and the manual are placed behind.

 

img_2724.jpg?w=291&h=300

all of the supplied accessories.

 

Accessories: VSonic doesn't cut the corners with the included accessories; almost everything I could imagine to get with an IEM is included, especially the tips amount, which is very generous. The following accessories are included with the GR07: a spring snap soft carrying pouch, made of a leather-like looking material. A hard clamshell case could've done a better job. A pair of silicone ear-hooks is included too; I have some things to say about it, but they'll be kept for the "Comfort/Fit" section of the review. As I said before, the amount of tips is very generous; there are actually 13 different pairs of tips included: A pair of a Comply tips clone, a pair of silicone Bi-Flanged tip (Medium sized), 3 pairs of Hybrids look-alikes, with foam in their inner core (Small/Medium/Large), 3 pairs of Single-Flanged silicone tips (Small/Medium/Large) and 5 pairs of regular Hybrids look-alikes (Extra Small/Small/Medium/Large/Extra Large). It was very nice to get so many accessories, and I believe that the GR07s truly deserve to get a 10/10 score for this section.

 

img_2727.jpg?w=225&h=300

 

Building Quality and Design: The GR07's build is mainly plastic, though, it's very solid, strong and sturdy. The housings have the words "GR07 WALKAUDIO" embedded on it. On the other side of the housings, the "R" and "L" markings are embedded too. There are two tiny venting holes: one on the housing and another one on the strain relief, to help reliving pressure. The metal nozzles can move to any wanted direction, which is a patented VSonic technology. The sound hole is covered by a metal mesh, protecting the drivers from ear-wax from falling into them. The strain reliefs are a bit too rigid, though, they can still do their job quite good. The cable is made of Silver, covered by a plastic tube to make it more durable; it looks to be of good quality. The cable ends with an L-shaped gold plated 3.5 millimeter jack. The building quality of the GR07s is nothing to worry about; they seem to be very well built, and it looks like a lot of considerable thought had been invested into their functional and durable design. The rating is 9.5/10.

Comfort/Fit: The comfort and the fit are very good, due to a few reasons: The square shaped driver housings just disappear in the ears because they're quite flat. Another reason is a VSonic patent, called "The moving nozzle"; the nozzle can move to any direction you'd like it to, so fit isn't a problem at all. The provided "Hybrid Look alike" tips are offer good comfort, they're pretty soft from the outside and more rigid in their core. The cable doesn't do any problems with the over-the-ear wearing style; it stays in its place and it's not causing any discomfort when touching the skin, because it's quite smooth and pleasant to touch. The provided ear-hooks are terrible, they're pretty much unusable; the cable pops out of them and they are quite uncomfortable, but they're not really needed, so it isn't a big problem. The rating is 9/10.

The rating is 9/10.

 

Sound Quality: Before the review, I had given the VSonic GR07s at least 160 hours of Burn-In, as recommended for this specific IEM by a lot of Head-Fi users. There were some small changes, mainly in the treble area: Out of the box, there was quite lot sibilance, though, after the burn in period, it almost disappeared. Also, the treble got a bit smoother, and it now extends better. The bass has now a bit more weight and body, and like the bass, it extends better too.

 

The sound-signature is balanced, warm, musical and smooth. I get relaxed with the GR07s sound signature, because it's not fatiguing at all, I can listen to it for a very long time without getting bored or tired of it.

 

The Bass: The GR07s bass is very punchy, and even though it uses a dynamic driver, it tends to be quite fast. It's very accurate and well controlled and textured. Also, the fact that the whole sound-signature is balanced doesn't mean that the bass lacks body, vice versa, it has a full body and it has enough weight to feel natural and real. The drums presentation is very unique in its naturalness and realism.

 

The Mids: The mids aren't laid back but they aren't forward either; they're quite neutral. They are very clean, clear and accurate, managing to reproduce impressive detail layers.

 

The Treble: The treble has a very good extension, which gets even better after the burn in. Before the burn in, there was a lot of sibilance, but it got away when the GR07s had passed the 150 hours of burn in. After the burn in, it got a lot smoother and non-fatiguing. Like the mids, the treble is very detailed and clear. Also, the treble is very crisp, leading the vocals to sound very good.

 

Sound-Stage and Imaging: The GR07s sound-stage is very wide and quite airy. Imaging is very good either; a good picture of the played audio can be imagined easily. The instruments separation is good, and the layering is too.

 

The rating is 9.5/10. It's rated in ratio to the current price.

 

img_2728.jpg?w=225&h=300

 

In Conclusion, for their current price, the VSonic GR07 offers a very impressive "Bang for the buck" value. It's an IEM that could easily stand against more expensive competitors without any shame in all of the categories. I salute VSonic for building such a magnificent IEM for such a low price. The only average thing that the GR07 does is the isolation, though, some of its competitors do it worse. For the great value that it offers, the VSonic GR07 receives an outstanding score of 9.7/10.

 

img_2744.jpg?w=300&h=229

 

The VSonic GR07 is officially priced at 179$. It can be purchased through different dealers, for example: Lend Me UR Ears, Frogbeats, Amazon and through the top-rated eBay seller, bigbaragainonline.
