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.
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
Cable: 1.3m Silver cable
Connector: 3.5mm Gold-plated L-plug
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.
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.
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.
the 3.5 millimeter jack 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.

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.
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.
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.

Pros - Sound quality, comfort,
Bought these about two months ago and I'm delighted with them. The audio quality is fantastic compared to my last ear phones and they are still suitable for every day use.
It is the best of the best at having no flaws. Very good overall at most everything.
Pros - Excellent sound quality, good value
Cons - Minor build issues
These are my first pair of upper-mid tier IEMs, so I can't really compare these to anything else in their price range. I can say however, that they sound very good to my ears, with much better bass extension than my A151s, and a nice midrange and overall more balanced sound than my M50s. However, they don't have the world's best isolation, and there are some minor build issues, such as the plastic strain relief coming unglued from the housing, though it doesn't really move around and it's easily glued back on. In addition, the strain reliefs on the y-split and the plug are a bit stiff, since the cord is pretty springy (which can be a pro or con, based on preference), the strain reliefs aren't super necessary, but it can still be a bit annoying. Overall though, very recommended!
Pros - Excellent
Cons - Need a long break in (200 hours at least)
Buy these if they are in your budget, you won't be disappointed, very analytical phones with great sub bass reproduction for a IEM
Pros - Balance and it good for just about every genre
Cons - ear guide can be a pain
Gr07 is perhaps one of the best IEMs around in value/price. They are balance and just about every Genre i listened with them ain't bad at all. You can't go wrong with them. The only issues one might have is the fit, and the earguide
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.
