I wouldn't give the review even a 1 star rating. Too much going on to mention and not in a positive manner.
 
You obviously didn't get a proper seal and instead point fingers at the earphones.
 
I have the R3 and they need amping and a proper fit which can be achieved by tip swapping. Bass is very punchy once you get there as running
 
them off a weak DAP/Phone will result in poor performance. Try them again and report back.

i would advice you to read reviews before buying and make sure that you are getting a proper seal. Good day mate, happy new year.

gikigill, sorry but i wouldn't give this comment even a half star. first, i can't report back because my item is already returned as my review and profile says. second, i don't use any phone or other mobile thing, what i use is again writes on my profile. why don't you get a proper read on my review and profile then report back ? (third, i really have no idea what "quite punchy" means. i work with comparisons) 
 
thanks for the contribution but you should know, if an earphone needs an amplifier it does not have to be the perfect earphone when amplified. same goes for the seals. if you tried hard to get a seal, it does not have to happen with me too. and when sealed, that particular earphone does not have to be the perfect earphone when sealed. i don't know if i'm telling myself right ? 
 
suman134, which reviews i should read, the ones that says brainwavz m2 is a bass monster or xiaomi pistons has a great soundstage, or the ones that says koss earphones are trash ? i'm a little confused here. sorry mate, new year.

they are true mate, M2 got enough bass, pistons do have a good sound stage and koss are not good enough, there are flaws in everything. you have to settle with some.

Not offending you; since most of your complaints are about soundstage / separation / bass / imaging and you were dissatisfied with 90% of earphones you purchased, you should really use headphones instead. I have AKG K518 ($40), a headphone I only have, and I find the soundstage is very vast and big despite of its closed design; yet,  it's not even an expansive-soundstage headphones at all. I mean big soundstage when compared to earphones even to the great soundstaging earphones like IM70, EPH-100, W4, and even DN-2000. I have 24+ earphones in my collection and none of them have soundstage that's close to that headphone ( but I still appreciate those and love them). I find headphones have bigger speaker, obviously, than the earphones so the perceived soundstage is different.
 
Hope that helps.

Oh one more thing, AKG K518 is the only most isolating headphones I have; the other headphones I own are given to my relatives. So if you find your need for earphones due to isolation, AKG K518 is the answer; trust me, its isolation is comparable to IEMs but only if you can get used to its tight clamp. That headphones is small-sized and may be uncomfortable for bigger heads

It is clear you prefer a more aggressive sound. The R3 are much more refined, better coherence,  highs are smoother but still very extended, and with EQ the bass will outclass the ostry... fit easily goes to the kc06/a.

Brainwavz R3 are quite good in my book, smooth everywhere and not boosted, with just a bit of extra warmth, quite recessed upper registers and shy sub bass, but still a nice sounding IEM. In terms of soundstage, R3s are very good, probably better than EPH-100.
 
There's a chance you are not getting a good seal.
 
Maybe you just don't like the more mid centric and sweet nature of R3s
 
If you make a review hoping the wrong things, it may end up like this one. It's like reviewing a Senn HD650 wanting them to sound bright and aggressive with subwoofer-like sub bass. It might end with just 1 star, no matter how smooth and cohesive it sounds.
 
Just my two cents!

You sure have a lot of 1 star and 5 stars reviews... The scale doesn't go 0.5 - 1 - 2 - 5. Giving a non aggressive review if you don't like it goes a long way.

Well obviously it doesn't have enough bass.  It isn't the B34t5pr0.

all i am saying, as others i believe, is that the review should not be solely based on whether or not you like them. you should try to be objective about how they perform, and consider things like price and fit, and still not recommend them,

I dont look at graphs, and never gave them much credence... I noticed your other reviews, which leads me to the conclusion you rate them purely on whether you liked them or not, without considering if they would be good enough for others to like. Your review does give good comparisons, but the star rating does not reflect the review. One star means plain bad.

Just for example, if you heard a very flat iem, like the er4, you would probably not like them at all seeing they would not satisfy in bass. That wouldn't mean they deserve one star. The Sony H3 is a bassy item that is very capable, but I was not a fan of the tuning. I may not recommend them, but I would not give them one star. Do you see what I am saying?

There is always subjectivity... No one claimed otherwise. A review should try to present what it does bring to the table for everyone.

Hm, you should try some high performing budget earphones and avoid crazy-ass expensive earphones since one expectation may be too high on that. In my experience, the more expensive the earphones, the more unique sounds they get and the sound may not satisfy one's taste. In fact, expensive earphones are designed for special needs. Like UM3 pro, a $399 earphones, (I had it as replacement for an old broken Um3x) it's very very intimate (small soundstage) and laid back earphones and you might hate it; but its made for in-stage monitoring. It's got separation and imaging, yet relaxed treble that allows one to pinpoint where instruments come from without getting distracted. Or W4, as expensive as UM3pro, is a balanced earphones that gives no "wow" factor as the price suggests, but it's designed for long listening without being fatigued.
 
In regards to some high performing budget iems, I'd like to hear your opinions bout Philips SHE 3590 in future. Put a pair of Sony hybrid tips on it and I joke you not, you'll immediately rate em 4-5 stars. Oh and Nuforce NE-600X is highly recommended for wow-seekers. But, the stock flanges are darn short so pair 'em with double flange tips and your earphones journey ends there. Above all, most dynamic driver earphones ( not BA) need some time to burn-in to do its best job so I wonder have you done those before reviewing it? And tip-rolling is important to get the best seal you need.

Also, when you purchase expensive earphones, let'em grow in you. It may take some time to get used with the signature; then you'll highly appreciate the beauty of it. Try give some weeks or months before concluding, except if that earphones totally fatigues your ear or give some pains. Hope that helps!

It's the SHE3590, not the SHE7000, sir. I've tried the 7000 and it's not good (shallow sounding, lack of musical separation, grainy mid and shrilly treble, I recall) but the 3590 is the real deal. Well next time you review about something, try write more and put more thoughts about what you complained aside of the sound like the fit, isolation, etc, including what pains you the most. It because fit, comfort, and isolation are also important criteria IMO. I find the R3 has weird design so I'm sure the fit is very terrible. On the other hand, you have the right to express your opinions so it's cool with your review man, but it's just bit too short ( I find you write longer in your comments than the review ). 
 
 
Speaking of the Piston, to be honest I love it though but I wish the included stock tips could be little sturdier since they're bit mushy and don't seal well. I had to buy aftermarket tips but luckily it fits and conforms well in my ears. But overall, they're good sounding, fun, V-shaped (which I like but not deep V's), lacks of bloat IEM and soundstage is quite expansive for the price though it's not comparable to the $150 EPH-100. I've bought 2 to my friends for X-mas presents including the tips and they loved it so I believe Piston doesn't do any wrongs.

i agree with Gandasaputra, diminishing returns is something some people are willing to pay a pretty penny for. 
 
It is clear you prefer a certain sound signature, and recommend the earphones you jelled with. 5 stars for vsonic g/r02 despite "lack(ing) some bass & not big sounding as others" kind of presents a like/dislike rating system. I personally thought the kc06a had treble that was too aggressive, losing out in refinement... esp next to the R3. There is nothing wrong with preferring a sound signature, but keep in mind that your review is being read by people with different tastes and a 1 star rating does not do them justice.

It's cool man, I understand your reasoning; I didn't think that interaction like these, in comments, are much enjoying than reading just straight reviews. But in some reviews there's still interactions despite how constructive they are. Guess this is the most active reviews I've seen with the most active author. But hey, look forward in your next reviews and please write little bit longer (like the piston review you wrote). Also, I like how every reviews is titled; it's quite creative. I've read the piston review and I quite enjoyed it, so that's what I meant bout the review!
