Pros: Fantastic balanced sound, low distortion, strong build quality, new low price

Cons: Slightly sibilant

Not An Introduction

 

This in-ear monitor does not need to be introduced, yet again, to headphone audio enthusiasts. The GR07 is one of the most popular high-performance IEMs on the market; at its original MSRP of about $180, it represented one of the best deals in headphone audio. It competed evenly with many IEMs that sold for much more money and suffered few compromises in order to achieve this performance, despite its inexpensive price tag. The GR07 have been released in several iterations since, the latest being the Classic model. Supposedly identical to the GR07 Mk II, the Classic offers the same great sound that VSonic is known for, complete with multiple color options and an even more attractive price tag, $100. I am here to confirm that the GR07 is still one of the best deals in headphone audio.

 

Sound

 

Tuned to sound similar to stage monitors, these sound a little more colored than reference-grade neutral, but no more than just a little. A very small mid-bass hump provides additional oomph in beat-centric tracks, such as pop or hip-hop. More problematic to some is its tendency to sound a little bit bright up top. Without using equalization, the GR07 can occasionally exhibit sibilance and a brighter sound than neutral. Due to slight variances between units, it is impossible to accurately describe the severity of this problem, but for those who are sensitive to sibilance: look elsewhere unless you are willing to use EQ to correct these problems. For reference, my particular pair sounds more even when EQ’d about -4 dB at 6 kHz and -3.2 dB at 10 kHz. Some pairs my need more or less than this and at slightly different frequencies in order to tame the treble.

 

Distortion throughout the entire audible range is not an issue. If any is present, it is low enough such that it is not audible at any point. All frequencies are presented in a clean manner. Many people have reported resonances in the treble which contribute to the brighter overall sound of the GR07. These cannot be entirely corrected by EQ, but when EQ’d properly, the IEMs should not be too bright to enjoy. Any ringing resulting from these resonances seems to be fairly short-lived.

 

Build

 

The GR07 Classic is the same IEM, with respect to build quality, as the original and Mk II. That is, the earpieces are very solid, high grade plastic. The rotating nozzles on the earpieces are made of strong metal and are unlikely to break, except under very high stress. The cable is the same as the Mk II; it is soft and flexible and feels reasonably strong. The only problem that seems to have carried over to this generation of GR07 is the short strain relief extending from the earpiece. Since the IEM is worn over ear, the cable should not be bearing significant stress, so I do not believe this will be an issue, either.

 

Accessories

 

Accessories are slightly downgraded from older VSonic offerings; no longer do buyers receive a billion tips with their IEM. That said, the ear tip package is still not completely disappointing. Included is one pair of foam ear tips, as well as a pair of bi-flanges and three or four pairs of different sized single-flange ear tips. Also included is a pair of cable guides to assist in over-ear wear and a small faux leather pouch to carry the IEMs in. I would have preferred a hard shelled case, but if the user is careful and mindful of the case’s limitations, this hopefully will not result in broken IEMs. IEMs at this price point have been improving their accessories packages recently, so this is slightly disappointing to me. However, the accessories presented here are at least adequate.

 

Closing Statements

 

Overall, this IEM represents a truly fantastic value. It has become an even better deal than it used to be, sporting a new, low price tag, complete with the same GR07 sound that made it famous about three years ago. I would absolutely recommend this IEM to anyone looking for an inexpensive high-performance earphone.

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: Detail retrieval, lush/articulate across the spectrum, crisp, extremely clean and fast/dry, great "open" feel with very responsive dynamic range.

Cons: Perceivable peaks and valleys in the treble region, detail retrieval/articulation almost to a fault with some "smooth" genres like classical.

After owning the Vsonic GR07 Classic Edition for about 2 months or so, all I can say is these are absolutely brilliant.

 

Very articulate, fast/dry sound. These will extract details almost to a fault, to the point where classical music isn't realistically presented for the most part, due to overly in-your-face presentation.

They are quite neutral, however have a full low-mid area and a 6.5kHz peak, a build to a 10K peak, then a dip around 12kHz and then another peak above that (se for example  innerfidelity for a detailed FR graph).

 

For critical listening, they are probably not as spectrally linear as you'd need.

 

However, they have a mildly scratchy/papery quality to them that is irresistible to me, thanks to the 6.5KHz peak and the overall extremely vibrant, articulate response across the spectrum (they never feel like you have a smooth, solid wall of sound against your ears, but always manage a detailed, vibrant, rippling surface that effectively prevents listening fatigue).

Drums and guitars, and other sounds with snap and texture, are absoluely superbly presented. Thanks to the great fast response, 6.5KHz focus point and fast decay, movies with gunshots and other action-related sounds with fast transients are also rendered incredibly snappily and crisply.

 

Sibilance can be a problem in the 6.5KHz area, however after adjusting to it most other headphones sound overly polite in comparison.

 

Overall a light, airy sound with great articulation and dynamics across treble, mids and bass. The papery aspect is particularly descriptive of them, take a paper and rip it slowly, that type of dry, quick, scratchy, crackly sound is the trademark of these things and adds the richness they possess, yet they are extremely clean and free from distortion.

 

For the current price of 100$ I really cannot recommend these enough, they have a unique signature and presentation that is incredible for metal/rock and action films, and will deliver a very detailed sound in all cases, as long as absolute linearity in frequency response isn't critical. I have a pair of Beyerdynamic DT880 which have a similar balance, and those feel like a very good linear companion to these, lacking the pronunced 6.5KHz area and the dip above it. Even with the Beyers and their more natural, airy, slightly more spacious sound I still reach for the GR07 alot, particularly for action films.

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.

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.
