So my Livewires arrived today a little over a month after my impressions arrived at their facility. Not too bad for turnaround, just a few days longer then what I was quoted. Initial fit is very good, I can walk and chew gum and not lose the seal. (I know, who would have thought that I possessed such mad skillz??) The left goes in easier then the right, but I'm sure I'll learn how to put them both in efficiently and once seated they are as comfortable as my Ety ER4Ps.
Initial, I had five minutes during lunch, impressions are that they hiss like a bastard out of my Ipod Touch. This was pretty much expected given their insanely high sensitivity and I pretty much assumed that I was going to need to use the PtoS adapter that I have at home with them. For me getting these was not about the ultimate in fidelity. I'll report later once I've had a chance to try the adapter. If they still hiss with that I'll be hard pressed to justify keeping them and this is why I went with Livewires in the first place, 30 no-questions-asked money back warranty.
