Two full days with these and I am still just blown away by how great they sound. I expected it to take some time to at least adjust to the sound signature since I had been listening to the IT03 as my daily drivers for months, and even when I got the LZ A4, which I think are quite good, I had a hard time adjusting, to the point that I still pretty much exclusively used my IT03.
Two days with the vegas and I am hooked. Which is really good considering that first listen didnt wow me and considering how expensive they are. They are possibly some of the most comfortable IEMs I have owned, and the sound is just, well, all the detail I could possibly want, in a sound that is somehow balanced yet somehow also has huge bass, forward mids, and pretty sparkly airy treble (though not quite as crisp as my ba iems, which I am thinking is actually a good thing).
I am really not a fan of foam tips, always had problems getting good seals with them and I am just not a fan of having to replace tips on a somewhat regular basis. Started with spiral dots, but on tracks that were already sibilant, was finding them slightly too harsh. And I think as someone else had mentioned, I think the seal was just a little too good on them, the bass was possibly too boomy and I had some weird pressure issues that I could feel when I moved my head. Kind of hurt my head. Currently settled on the medium (maybe medium large, the red ones) spinfits. Dont know how the sound compares to foam (since I cant get a great seal) but I am not having any of the issues I was having with the spiral dots. I do have a pair of those interesting looking mandarines symbios hybrids on the way, and am hoping those will be even better.
I am a happy camper with these, and at least for the time being I find myself completely satisfied, which I hope means my wallet will be happier with me going forward.
