Got these in today and have been listening to them for a couple of hours.
Three things I immediately noticed when I put them on (and this is me coming from SoundMAGIC E10 user):
I gotta say WOW, HOLY BASS BATMAN!!! The quantity is definitely there and it goes down deeeeeeep, like their rumbling sub-woofer deep. I gotta say that I think these go the deepest among all the bass-biased headphones I own (PRO 900, D7000). It literally feels like I have a sub in my head. Now, this is coming from a guy who loves good bass so if you're not a bass person, stay away!
E10s are also quite bassy phones but there's a BIG difference between E10 and vPulse.
Now that I sorted out the bass quantity, how about the quality? I think it's quite good. Of course, there's a lot of it and it makes it slightly difficult to judge but it doesn't feel bloated or boomy at all. In fact, sub bass is a bliss! Mid and upper bass are quite good as well. Not as tight or clean as the full-size cans mentioned above but enough to satisfy most picky bass lovers. Yes, bass is overpowering in bass heavy music but if you listen/like bassy heavy music to begin with, you will probably love it.
I believe if you get noise blocking tips like Comply, I predict there will be even more bass which would be unimaginable even for me.
Did I mention these have AWESOME BASS?
Immediately after I put them on, I noticed a significanly wider soundstage compared to E10. Dare I say they sound like closed full-size phones? Possibly to some cans. I only know that I much prefer this soundstage over E10. The different was easily noticeable between the two.
This is where vPulses are not as good compared to E10. Granted, E10s are feather weight, super light but vPulses are somewhat heavy. This is due to the flat, tangle-free wires but I don't find them to be problematic enough to cause any comfort issues. But just enough to make you notice at first. After a while, I don't notice the weight. E10s got some serious microphonic issue when worn down but vPulses are much better at controlling microphonic. Overall, although the wires are heavier, I do like the tangle-free feature and prefer this over the E10's thin, rounder wires. I also prefer the vPulse's 90 degree plug over the straight.
I believe vPulses can be worn only downward due to their angled tips. They do fit my ears perfectly thought which is rare.
AND THE REST
Again, compared to E10s, mid and high are both more forward and brighter which are welcome changes for me.
Did I mentioned they come with an inline iPhone controller and mic? Well, they do.
I wasn't expecting much due to lack of interest in them (no head-fi review was done) but boy, was I surprised. This was another holy cow moment for me like when I discover PRO900. For Velodyne's first attempt at IEMs , it's not too shabby at all. Now I know why I love Velodyne subs
If you love bass but don't want to sacrifice everything else for bass, DEFINITELY try these. These are quality all-around IEMs with a kick (bigass kick for that matter) in the bottom.
Three button inline control
Comes with a carrying case covered in suede-like material
Comes with a clip and 4 pairs of tips per color (total 8 pairs)
All listening has been done using BIFROST/ASGARD/FLAC. Have not tried on an iPhone yet.
I just realized that half of what I wrote says "bass"
