Ofc.But delivery will take long though:18-42 days
I use a cold sounding source and I don't have a good amp.Should I use an amp with these?
Yes a fair few now. Maybe that is how long to the restock!
The Xp3 is the most balanced of the three and the XP1 is the bassy one closer to the VB. The XP3 is the best of the XP's in my opinion and still has good sub bass just to comparable to the VB, the rest of the frequencies and overall clarity is better though. If you want another bassy earphone then get the XP1 and if you want more balance then the XP3.
I have not heard the EPH-100, sorry!
Really, is this Jaben? That sucks, have you tried asking them if they can sorts something out for you?
