@WAV Hunter : A63 has more emphasis on upper mids, it's brighter and more detailed.  T1E is opposite, where the emphasis is shifted to lows with deep sub-bass and more aggressive mid-bass punch.  If you are comparing T1E vs A63 and want satisfying bass impact for the style of music you listen to - T1E is a better choice.  KC06A will be good as well if you want more details without too much brightness and don't care about deeper soundstage.  VSD3S are good as well, but they don't have the same low end punch as T1E and KC06A.  Btw, I just got VSD1S for review as well, apparently VSonic redesigned it with a better cable, etc.

Thanks for awesome review!

@twister6 : Thanks for the info. Which would you say is the brighter IEM, the KC06A or the A63? Thanks again.

@WAV Hunter : as I mentioned in my reply above, A63 is definitely brighter.

I have been using these things for a while and I really love them! All I can say is that the SQ really goes beyond the price range. Whether you plug it into your iPhone, AK120 or whatever source you have, I'm sure that you will feel astonished as I do.

How about comparing the TTPOD and HABY B3 Pro 1/2?

@egosumlux : its already in my review above, in the last paragraph before the summary.  Don't have Pro 2 (that one is not that good with it's enhanced bass), just have Pro 1.

great review, any chance of comparing them to Sony XBA-H3?

Did you tried tip-rolling? I compared the T1 and what i remember from the T1-E to my IM70's and despite the fact that they weren't superior, i still enjoyed them. I felt the bass, though decent, had more control but not losing impact on my IM70's with Sony Hybrids. The housing is more comfortable than the IM70's, though after a long period of time it gets annoying (but that could be me, i got used to using on-ear). The only big issue i have with it, is the freaking cable. When i get them out of the pouch, takes me around 2 o 3 minutes to untangle them, and i've only had them for 5 days, give or take.

Sorry I got past it, my bad . I think the new chinese potential giant killers deserve their own comparison thread for every 2 months or so we get a seemingly better contender (maybe just FOTM) and it's getting a lot harder to recommend a good mid-fi IEM nowadays

@oxygen1 : sorry, don't have H3.  You should visit T1E appreciate thread and post a question in there.  I'm pretty sure Hisoundfi will chime in with his reply since he has both.

The sound Sig you described matches the 1p2, any chance you can compare them?

They look like the JVC fxt90 and the IE800 had a baby. a clear baby. do these use the old twin driver from jvc?

design looks copied from ie800, surprised sennheiser hasn't sued them yet.

$50?!?! Wow! 

How does this pair compares to Hippo VB?  Thanks.

So are vocals fairly upfront?

vocals are not exactly upfront, but nicely balanced with the low end.  Definitely not v-shaped/recessed like you would expect in a commercially tuned in-ears.  But be aware, tip rolling will change the sound where narrow bore tips will attenuate the sound to filter out highs, thus bringing more bass upfront!
 
Btw, I'm getting a lot of request to compare these with other headphones.  Unfortunately, I don't have a lot of those mentioned IEMs, so I think it would be a better idea to post these questions in T1E appreciate thread where more people subbed/reading and can offer their comparison review.

How is the fit, seal, and sound of over-ear vs. cord down? Thx.

@H T T : I didn't notice a difference in sound, though found fit over the ear to be more comfortable.  YMMV since we all have different ear anatomy   You should visit TT1E appreciation thread, there was quite a number of posts with people showing pictures of how they wear these IEMs.
