Tronz, I hate to say this, but we will never be friends. Not because you don't seem like a nice guy, but you're luring me into things! I think I have to contact Variphone to get some details on the ES5's, including price.
With regards to comfort, I can't imagine acrylic customs are uncomfortable, but probably not as comfortable as vinyl or silicone. However, my uses will stretch towards 5+ hours at a time. Sometimes more, sometimes less, of course, so comfort definitely is a priority, but also the main reason I want to go custom.
What's the build quality like on Westone customs? Are there bubbles or anything like that? It seems like it's hard to avoid, but it's just another thing to take into account.
The built quality is top notch. No bubbles anywhere that I can see and the shell is buttery smooth with no manufacturing scratches or dimples. The cables are amazing as well. I thought they weren't going to last past 3 months because they look flimsy, but once you hold it and pull and tug in areas you thought were weak, you'd come to realize that these things could be used as a bicycle chain. They are also very comfortable because of their light weight. Also, when I go running, the cable doesn't channel that annoying " thud " noise when it bangs on my chest into the music.
