Concise Multi-IEM Comparison (VSONIC GR01, GR02 Bass, GR06, GR99 added, April 24th, 2012) - Page 30

I don't know the answer. I never listen to the newer VB so I am not sure if you are getting a better or worst deal by selling the VB3. All I can say is E30 is great for its price.

HiSound Audio Popo and (Golden) Crystal added.

Analytical 5.    HiSound (Golden) Crystal (link)
The sound signature, in short, can be described as the dynamic version of the Brainwavz B2. It is bright and analytical with a slightly aggressive presentation. Bass, though no abundance by any mean, has really good body and impact that are not often found in analytical IEM.  Mid is placed slightly away from the listener but not enough to really call recessed. Thought it lacks a sense of thickness, the overall detail of vocal is still very clean and decent. Treble is crisp, sparkly, well extended and full of micro detail. It can be slightly harsh on bright passage, but never quite as the more aggressive B2.  As a dynamic transducer based IEM, Crystal offers something different from B2. That is, it is more specious, textured and with a better bass reproduction while B2 offers better speed, resolution and fine sparkle. Those who find B2 to lack a bit of the lower end or just a bit too much on the higher end will likely find Crystal to be the perfect substitute as technically, the two are very much comparable with just a small touch of different in presentation.
Pro: Good cable.
Con: Odd naming between batches. Lack of chin slider.

Warm + Sweet 8.    HiSound Audio Popo (link)
It is hard to define how ‘woody’ sounds like by words, but there is always a sense of lushness caused by reverberation of the wooden IEM housing that are pleasing to the ears, though it might not be the most accurate sounding. Like many woody IEM, Battleflag (Popo) carries the lushness of the wood into its warm and sweet sound signature. While it is quantitatively above average, bass can often be boomy but shallow in depth. However, it is not boomy enough to be offensive and in fact, quite enjoyable for casual listening. Though it is classified as being sweet sounding, the mid isn’t particularly forward. It has enough warm and thickness to keep pace with bass and give it some sweetness, but back away enough to reserve a sense of space between the signer and the listener. Treble has good extension but missing some of the top end sparkle – not something very noticeable unless you are looking for it. It is decently crisp but overall smooth and tends to trail behind the mid and bass. Soundstage is pretty good, airy, specious but more immersive than it is transparent. Technically, Battleflag is not strong in any particular area. But as a whole, the sum is larger than its parts. It is rich, it is lush, and most importantly, it is fun and relaxing to listen to.
Pro: Price. It sounds much better than its name.
Con: Name. Lack of chin slider. Very mild driver flex.

I prefer it over M2. As for Eterna, it is a different story. There are some music that Eterna just sound so great with, but it has its technical flaw as well (i.e. strong coloration, etc). As a universal choice, I'll say Popo makes a safer bet.

No, I didn't feel a lot of pressure with Crystal. It is about average.

No.MR2 Pro doesn't have the same housing as PL50. It has very similar housing to FA's Omega. The nozzle is more angled than PL50.
I'll say SE215, but they are very close in performance with different presentation. This is why I've given them the same score in SQ.

Well, it is darker than most dual driver I have (at least when compared to most TWFK based dual driver like the B2). Kind of Shure like actually. But for the price I paid (around $135), I can't say I have any complaint. It is however quite underwhelming as the 2nd in line after TF10. I thought it should have been better sounding.

I might have a chance to review some of the XBA models, but I'll have to confirm it with the local Sony PR first. They are actually launching all the XBA locally tomorrow on a press event but I won't be able to make it there.

EXS X20 added.

Analytical 8.    EXS X20 (link)
The overall sound signature, in short, is the tamed down version of B2 / DBA-02 - lean, clean, neutral and bright sounding – but different from B2 (and DBA-02), X20 is less aggressive on treble presentation, has less body on the bass end and a smaller soundstage. Bass has decent speed, but rather light in quantity, especially on body and depth. Mid is slightly forwarded on the whole presentation, but only just. It is a tad sweeter compared to the more neutral B2. Treble extends to the top, well detailed and with a very good amount of sparkle. It is bright for sure, but not quite nearly as aggressive as B2. Soundstage is only average, nothing to write home about. Respond really well with bass EQ or bass boost amp like digiZoid ZO.
Pro: Smoother sounding then B2 with the same sound signature. Build quality.
Con: Availability

 

No, both Sensaphonic Japan (the j-phonic main distributor) and j-phonic are still in business. But due to the poor international sale (partially because of the high Japanese Yen exchange rate and weak international economy) they have decided to stop selling internationally and instead focus only on Japan's mainland market from 2012 onward. That's why you can't find them anymore as they have shutdown the international site.
