Rated #4 in Universal Fit


Pros: Comfortable, Fairly Balanced Sound, Solid Isolation

Cons: A Bit Sibilant, Housing Cable Relief Requires Care




  GR07, Vsonic's statement in the IEM world. Featuring a Sony-licensed 11mm bio-cellulose driver, it was unlike anything out in the market. IEM's have come and gone, upon release many get hyped and overrated, but loose their sparkle over time. GR07 has proven to be able to withstand time, because it is simply a great product. At this time, despite the VC1000, GR07 is still considered the flagship product and has been mentioned to be the most proud achievement by Vsonic's CEO [interview linked on the bottom]. Time has passed and after the first GR07, a Mark II was released but then discontinued for the now GR07 Classic and GR07 Bass Editions. Both of which have the lower prices at 100$ and 130$ respectively, whereas the other models were about 180$. Here I'll be looking into both of the latest iterations of the GR07 and how they stand in today's competitive market. To note, the GR07 Bass Edition is about 30$ more than the Classic Edition as mentioned, I'll get into whether the price difference is worth the added cost. 



Packaging & Accessories

  Packaging is done quite well and it is presented quite nicely. Though to note, the previous packaging of the first iteration of the GR07 was quite nicer, but no big issue here. For tips, you get the Vsonic exclusive "Sony Hybrid" style tips of different colors, though these have wider bore than the Sonys. A set of single flanges, a double flange pair and a pair of foam tips. Then you get ear-guides and a soft pouch. Unluckily, there's another downgrade here as the first GR07 was packaged with a hard clam-shelled case, much nicer than the current pouch. I personally didn't have any luck with these ear-guides as I found them to be uncomfortable and slid off the cable too easily. Overall, I think you get a good array of extras here and packaging is done well.




Build Quality

  For the Classic Edition you get three color choices as shown below with a gray cable, while the Bass Edition only comes in black with a gray/red cable . The housings are plastic but feel quite sturdy and you get a metal nozzle that is adjustable. This is currently exclusive to Vsonic [Though Vivo XE800 borrowed this from Vsonic] and makes fit a bit easier for the user, an innovation from Vsonic that makes this IEM more "special".  It is definitely something very clever, that simply works. I find the cable great on these, it's sturdy and quite ergonomic. Strain reliefs on the plug are done well as is the y-split. Problem lies in the strain relief on the housing, according to a user here, the Vsonics aren't protected by a tangle inside of the shell [as is done on a lot of IEMs]. So if the housing is held in place and the cable is pulled too hard, it may just disconnect inside the housing more easily than expected. I recommend treating this area with care and taking them off your ears from the housing. Overall, build quality is solid but there are some competitors providing removable cables at a similar price. Of course, they also won't give you the great sound these Vsonics possess.  I would handle these with some care, though it is tough in some respects. To note, the cable does tend to get green with time due to oxidation. 










Comfort & Isolation

  These can only practically be worn over-the-ear, so that's something to note. Because their 6k peak in the treble does decrease with a deeper fit [more on this later], I wear them in that deep manner and while it is comfortable for the most part, there is some ear fatigue, though the fact that they're small and lightweight helps a lot. I use Phonak single flanges, but the stock hybrid style tips, Sony Hybrids and MH1 tips in small all worked for me as long as I got a deep fit. For a foam option, I recommend Comply T200. 


Isolation is solid on these but don't expect it to isolate like a fully sealed IEM. While the ER4 isolates -43db, the GR07 isolates about 24-28db in my experience. 




Sound Quality


    These are meant to be a studio monitor and by their signature it shows. I find it to be generally flat, with a mild bass boost accompanied by a midhigh spike and higher treble that is well extended but a bit laid back. InnerFidelity's graph, shows a well matched IEM between channels, with low distortion, portraying a quality driver in these. Efficiency on these is solid, expect it to get loud enough on quiet recordings from your portable player for the most part. On a very quiet old classic song I have, I do wish these would get a bit louder from my iPhone, but generally, volume should be no issue. I found these to sound best with tips that have a bore size that's about the same as nozzle's opening. If the opening of the tip is too large, expect the treble spikes to get bigger due to a horn effect.  


[setup: Deep Fit>Phonak Single Flange tips or Sony Hybrid tips in small>iPhone6


bass: This is where the difference between the Classic Edition and Bass Edition lies. When I first heard Vsonic were releasing a "Bass Edition" of the GR07, I wasn't all that interested. I found the bass balance to be adequate and was expecting them to boost the bass to levels to where the midrange will affected as it's usually the case. What actually occurred, was a very subtle boost in the subbass, midbass stays about the same. The boost is gradual from about 80hz all the way down [graph shown below]. I always found the GR07 to lack a bit of subbass, this Bass Edition remedies that and tastefully so. Upon comparing the two, I now understand the 30$ difference between the two. The Bass Edition is simply the definitive edition of the GR07. That's not to say, there's a huge difference, get to the other regions and the two editions are identical and as mentioned, the subbass boost is small. Those who want to experience the sound of the GR07 for the lowest price possible, opt for the Classic Edition, those wanting the best the GR07 can offer, should spend a little more for the Bass Edition. 


midrange: Midrange is nice and detailed here with a small hint of warmth. It is well represented and a little laid back. I'll say for the most part, these regions are done tastefully so. Midrange is neither too far back in the mix or too forward. 


treble: Here lies my main criticism of the GR07. Get to 6k and there's an apparent spike, insert the IEM too shallow another spike is at 8.5k. I was able to tame the 8.5k spike with a deep fit, but the 6k spike remains apparent despite of this, though also tamed a bit. The treble is bit grainy as it kind of dips between it's spikes. Treble extension is good, but could use a wee bit more air. Despite the spikes, the treble isn't that offensive with a deep fit, it's apparent, but never becomes really abrasive whereas an IEM like the Sony MDR-EX1000 can be. The treble does carry good presence and maintains the relatively flat response quite well for the most part. 


The GR07CE/BE aren't necessarily spacious, they have a more laid back, subtle sound, with only some soundstage width. The driver is fast and does image instruments fairly well, but I found it to fall short compared to certain BA IEMs. GR07BE has great extension at both ends, though I would have liked a slightly more extended treble, for a more airy sound. Overall, it's timbre is nice, though I found it to lack a bit of definition with higher pitched instruments. 


Below comparisons are done with GR07BE. 


Ostry KC06 Comparison: The bass edition of the GR07 portrays quite realistic sub-bass, a bit less in quantity compared to a modded KC06, with more realistic sub-bass compared to a stock KC06. The midbass levels are similar, with the GR07BE having a bit more bass control, with the KC06 having a little more warmth, midbass to lower midrange. The 1-2k region sounds a bit more refined on the GR07, overall the higher midrange sound similar between the two, with the GR07BE being a wee bit more refined. Get to the overall treble and the GR07BE has two apparent peaks, one at 6k and another at 8.5k. KC06 has peaks at 8.5 and 10k. I found the GR07BE to be peakier overall, with a deep fit and Sony-Hybrid tips I was able to tame the 8.5k peak but the 6k peak remains quite present. With the Comply S200, KC06's 8.5k peak is tamed and the 10k peak became minor. The KC06 has better treble extension, sounding more airy and open in these high frequencies, though a bit splashier than the GR07's treble despite being less sibilant. Overall, the KC06 simply sounds a bit more refined in the high regions with a smoother, more extended treble. Soundstage depth sounds a bit better on the GR07BE, but the KC06 is wider and more airy. To note, the KC06 also sounds more dynamic, overall it's a more engaging sound while being about just as balanced. On the contrast, there is some finesse on the GR07, the KC06 lacks, it's more subtle but a bit more refined. Hard to pick a winner here, the GR07BE's bass and lower midrange sounds more mature, while the KC06 sounds better in the higher midrange and treble. 

Hifiman RE400 Comparison: I couldn't necessarily do a direct comparison here, but I'll just make it subtle based on what I remember of these. The GR07BE has similar bass levels with a more realistic subbass, similar midrange clarity and a more balanced, extended treble albeit more prone to sibilance. Both are meant to have a more studio-monitor sound, but I feel the GR07BE is a tad better in it's role with a bit more balance and bandwidth, extending better at both ends. What I will give the RE400 is a smoother, less fatiguing treble, but it's a bit subdued for my taste. Outside of sound, both are really comfortable, but the GR07's cable feels far more durable. 
T-Peos Altone 200 Comparison: Here the Altone gives a more present bass. Problem is, I found the GR07BE more extended and controlled, whereas the Altone has a bigger midbass hump and a sub-bass roll-off. The Altone as a result has a looser more punchy bass, GR07BE has more rumble and control, more subtle but more filled bass. The midrange is warmer on the Altone in the lower mdrange, details here are less apparent. Get to the higher midrange, the Altone is very forward, to the point of being a fault. While this makes certain details more apparent, it simply sounds unnatural and edgy with higher pitched instruments. 3-6k is where the problem lies on the Altone, creating the mentioned effects. Treble is also peaky as well, though with Comply TS400, I was able to tame the peaks here. Both GR07BE and the Altone are mildly sibilant, the difference is that the Altone has this edginess to it's sound that's quite apparent. I was able to make the Altone more balanced with a 15ohm resistor, making them much smoother  but, doing this also made the lack of the treble extension more apparent. Simply put, the GR07 sounds a bit airier and open due to better treble extension, though the difference isn't huge by any means. Despite of this, Altone does place instruments a bit better than the GR07. Overall, the Altone comes off as this extravagant IEM, that simply wants attention. It's bass has a lot of punch and it's midrange and treble are detailed, but too forward for it's own good.  GR07BE on the other hand, is more laid back, but also more mature, as most of the frequencies are done at about right quantities, despite it's flaws here and there. I'll give the nod to the GR07BE, here proving it can compete and surpass IEMs above it's price. 


Dunu DN1000 Comparison:Here the Dunu carries more weight as it's bass it's more filled in the sub-bass. A friend of mine here mentioned that he found the DN1000's bass as slower, I agree to some extent but it's subtle, but can see where he's coming from. The bass of the DN1000 hits harder overall, so it appear to linger more, there's more reverb here. The bass of the GR07BE is a bit more neutral, but I found the DN1000's more subbass oriented bass more euphoric. The midrange of the DN1000 has a bit more warmth and it's also a bit more forward, compared to the more laid back GR07BE. In the treble the DN1000 does have a big peak that extends from 7-10k, so it can be as sibilant as the GR07BE. But these peaks can be tamed a lot more, than the GR07's. This means it's more finicky with tips, but the potential is there. After finding the best tip/insertion depth combination for both, the DN1000 simply sounded more defined in the higher frequencies. Mild sibilance due to it's 10k peak on DN1000, but the GR07BE was more offensive and yet a bit more subdued in certain regions in the high frequencies. Treble extension is better on the Dunu, so it sounds more airy and spacious While some may find the GR07BE's bass balance to be preferred, I found the DN1000 to be more rounded in the midrange and highs, with a more spacious soundstage with better instrument placement. While the GR07BE bested the previous hybrid, I would have to give it to Dunu here, though it is about 55-70$ more expensive. Outside of sound, the GR07 is much more comfortable, with smaller, lighter housings, compared to the bulky and heavy Dunu DN1000. 



Here I show how the GR07 Bass and Classic Editions will graph using the latest Olive-Welti in-room compensation. I superimposed InnerFidelity's data for this result and did some averaging in addition to sine sweeps. It is not meant to be 100% accurate. Things change with insertion depth, though all in all I feel this portrays the overall tonality quite well. I found this data useful for EQing as well, though the 10 peak is lowered to 8.5k with a more shallow fit based on tone sweeps I did for these. 




For under 150$, no other IEM plays the intended role of a studio montior of the GR07 [BE&CE] as well as these. They give that monitor sound, with a great comfort and isolation. I have my criticism in it's build quality and sound to some extent. With some cable failures being reported once in a while and the treble peaks, but regardless of this, I have great respect for this product.  I just recommend to treat them with some care and insert them as deeply as you can with comfort. Time has passed, IEMs have come and go, being hyped and then disappearing, but these are still being recommended, and for good reason....


I would like to thank user UnityisPower for loaning me the GR07 BE!!

Vsonic GR07 Head-fi Thread


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.




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.




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

Cons: Perceivable treble peaks prevent linear response, 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: 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

Pros: Decent sound quality

I have the Bass Edition.  They're good earphones.  I found the sound quality a little lacking in detail in the upper mid/treble range.  I'm not sure what that was about, since I eq'd them to near flat response - they just never sounded right with rock and heavy metal.  My Shure e2c's are much more detailed.  They did have nice extension all way from sub bass into the ~10khz range with a little help from the eq on the top end.  Overall, they do sound good (when sealed).  I like them better than the Sennheiser Momentums (in-ear) and the RHA MA750 as far as sound goes; the GR07 is more neutral and detailed than either then Senn's or the RHAs.  I'm not sure why these are marketed as the "Bass Edition;" the bass is pretty neutral/flat.     


I was never able to get a good fit/seal.  I even tried the meeaudio m6 triple flanges, but they went just a tad too deep into my ear canal and the included bi-flanges wouldn't remain sealed.  Something about the square housing and the nozzle prevented me from ever getting a comfortable fit.  Maybe it's just my ears; clearly others are having better luck.  OTOH, this is the first IEM that I found uncomfortable.  I do like the included earhooks and found a similar product on amazon for use with my other earphones. 


I do have to ding these pretty good in the value department.  You can get two pairs of the NVX EX10S for $70 or $65 for a single pair from sonicelectronix.com, and those are very close in performance to the GR07.  The NVX are probably made by vsonic for NVX or in the same plant that makes the gr07; I know NVX has used other companies to make their equipment on the car audio side.  That means you're paying anywhere from 2x to 4x the cost for the vsonic for a similar product.  The RHA MA750, which is in the same price range (but different sound signature), has far superior build quality.  The ~$100-$150 category is really competitive with some balanced armature IEMs getting into that price range, the Shure se215 has a detachable cable, many competitors offer a mic/remote in that price range, etc, etc, etc.   


Pros: smooth, clear, wide bandwidth

Cons: none for the price

The overall sound is similar to the Audeze LCD-2F - slightly on the warm side of neutral, but without the ultimate resolution the LCD-2F has. And easier to drive so you can plug them into your phone. The bass is all there but it's not bloated or enhanced like it is with so many IEMs. The treble is all there but at natural levels so they don't sound bright. The mids are just slightly recessed but still sound natural with classical and acoustic music. And the entire frequency range is integrated smoothly with no apparent peaks or troughs. That's quite a lot considering the price is around $100. Can't find much if anything at twice the price that has sound as good as this. They don't have reference level of detail, but enough for serious listening, yet still enjoyable and not fatiguing for long listening sessions.

I went through several different IEMs before I finally found these. Etymotics had crystal clear mids but no "air" with a rolled off top end. The other IEMs had muddy bloated bass. The GR07 classics were just right.

I can listen to these all day - and sometimes do.


Pros: Highly neutral, balanced and articulate. Bass is all there, not exaggerated.

Cons: Does require quite some hours to get rid of the sibilance mentioned by others. Not rugged.

With the strong dollar the GR07 "Classic" is currently $83.  It would be my nomination for the greatest value in IEMs, period.  One of the best in audio of all categories.  I had another pair for years and while not exactly fragile, I did a couple of minor repairs to keep them going for 5 years of gym use twice a week.  Some users will want to use tips other than included- I like the Sony.


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. 


One of the best all-rounder you can get for the money
