The cord on my SuperFi.3s is giving way for the third time, and Logitech didn't feel like replacing it for me (third cable in 6 months). Instead they gave me a 50% off coupon on all UE products. Originally I was eying the TF10s as my eventual replacement (since I can actually get my current IEMs to form a perfect seal on my ears) but since Logitech gave me this coupon I was thinking of jumping the gun a bit and getting the UE700s. I spent some time Google searching this site for comparisons, but I couldn't find much. I've read that the soundstage of the TF10s is marginally wider than the UE700s, but that it's nothing to hit home about. I've read that the 700 has warmer mids than the TF10 and that it sounds cleaner and more transparent. Less bassy than the TF10s also.
Does anyone have any further comparisons? In addition, how is the build quality of the 700s? I would like a replaceable cable, but if the 700s are built strongly I might consider otherwise. I know both will be an upgrade from my SuperFi.3s, but since I don't replace buds often I want this purchase to be worth it. I can get the 700s for about $80 shipped or I can go with my original plan for the TF10s, $184 shipped. Too bad Logitech still thinks the TF10s are worth $400...
