I just tried a decent Lyre audio copper cable and it settled the issue with sibilance for me.
As I promised I compared VX and PT-15.
Well, here it is:
The VX is airy with very high detalisation and decent overall balance. The bass is present and quite clean, but there is no punch. You know that fealing when you not only hear the bass but feel it? It is clearly missing.Just try Bonobo - Kiara to get what I mean - the punch should come with the beat. That is not a big deal for classical music (not all of it though).
The mids are clean, detailed, slightly moved back (like a single step).
The highs are clean, crisp, without "sandy" aftertaste. The sibilance is very rare, pretty much none existent. The violin is superb in these.
The build.
Steel. *****in steel. It is indestructable, but is so damn cold to use outdoors. Using these in -15 will leave you with a frostburn. The cable is feeling okay. It has a decent rubber cover, has a little memory, but not to a point to make it a big deal. The jack is ok. The only thing that troubles me a bit is the cable separator - no chin strap is not a big deal, but no strain relief is likely to be an issue. L&R can be differed not only by engravinds but by the bottom part of the earbuds - the left one has the ring-cut ( do not know how to call it correctly). The VX engravings are small and quite nice.
Overall the feel like a well designed and well made product. The sound was not made by accident, but by design. It excells at classic composition that do not have immense bass( Bach-lovers for example may be disappointed), the traditional chineese music, trip, trip-hop, ambient and country 9John. Not so good for hip-hop (some of Outkast tracks were ok, but Shahmen's - Mark is definetely not for theese earbuds), metal, core-genres etc.
PT-15 is airy still, the detalisation is no less than VX, but balance is strange. Let me explain. i tried it with Lyre audio cable, stock black and HCK-green-black cheapo cable. The sibilance was a big issue on two latter, but the first one soothened it a bit. But no matter what cable I tried there seems to be hump in treble area. Overall they are ok but sometimes you get a feeling of razor coming through your ear.
If we talk about about bass - the situation is more or less the same. The bass is heard but not perceived. Bass boost swith on Fiio A5 ain't helping at all.
Mids are good. Just good. Nothing superb, but nothing to worry about.
Treble extension is very good, more or less the same when compared to VX. The highs are pretty much well done. "Sandy" effect occured once or twice, but it was not systematic. The problem is that sibilance is there. Maybe it is easy to correct with EQ, but I hate to use one. Only with copper cable that costs more than the bud and VE foams I somehow managed to finish it off.
The build.
I do not know what the shell material is but it looks decent. The engravings are nice ( btw what do the numbers after PT15_*** mean? any ideas?). The connector quality is yet to be discovered, but so good so far.
With swappable cable there ain't much i can say about default cable - it ain't really bad, but ain't cool either. It is ok, especially given the price.
Overall the earbuds is good, but what you should keep in mind that this needs some tinkering to get it comfortable. Is it a problem given the price? No. It is a thing you should keep in mind.
Summary
The PT-15 and VX may be compared, because they (imo) have a close J(rather than V) signature. They are very different in terms of price, while being not so different in terms of sound. Yes, the VX feels more refined, but it is much more expensive and no cable socket. As I said the upgrade is in overall tonal balance. Would i recommend to get VX over PT-15? Not sure. I purchased it before PT-15 arrived.
p.s. Please take this with a grain of salt. I am not a professional and make judgements out of my own preception, which may be very different from yours.
Both headphones were purchased. I used Hidisz AP100-FiioA5 combo and .flac 16-24bit files for testing. Thank you for reading!
