UPS just dropped mine off.
I tried the silicon tips that were on them first. I was able to get a decent seal but they weren't too comfy.
I then swapped over to the small Complys. Much better comfort.
I noticed something about the fit. Looking in a mirror, I can see the UE logo on the right ear, but just the "e" on the left. This falls in line with my inability to use the stock Apple buds. I can never get the right side to stay put, all I have to do is breathe for it to fall out.
Man do these sound good. Right out of my little Shuffle Metallica's "Whiskey in the Jar" is really jamming. Gladys Knight & the Pips "Midnight Train to Georgia" and Don Henley's "Boys of Summer" were a couple of other highlights.
Reading other opinions of the TF10's had me a bit worried if the bass was going to satisfy. It does. It's not a bassy IEM, but I'm hearing all the bottom end, with nice volume and texture. The treble is also very smooth sounding but symbols and tambourines still shimmer
I'm so glad I'm a newb to upper-end IEMs and don't have any real frame of reference, because these are really nice sounding to me. If the mids are recessed in comparison to other IEMs, I'll just have to take other, more experienced users word for it.
EDIT: This is pretty cool. The TF10's, the little cleaning tool and my iPod Shuffle all fit in the case. Nice.
