Ok, I've had my 700's for almost 2yrs and my TF10s for 2 weeks so I might not be in a position to compare....BUT, my first impressions on the tf10s haven't been that promising really...
The 700s seem clearer (so far), especially with treble and mids..
The Triples have nicer bass, stronger it is but may be a little bit over?
I'm more into instrumental progressive metal (mainly and almost solely Dream Theater), Joe Satriani, Megadeth and classical...and I'm extremely annoyingly keen on details and the 700s haven't disappointed me as yet..They might need more powerful bass (I'm happy with the detail as it is)but that's about it...
When I want to focus on vocals (rarely happens), I go for one of my single drivers, either the UE SF-5 or the cheap-but-not-that-bad SoundMagic PL-50 :)
My only justification to buy the TF10 was the replaceable cable and this exactly the reason why I hate the 700s :(
As for seal, both are doing and excellent job, with the ear-sodomizing triple-flange silicon tips I'm using.
The only difference is that I added a cored comply foams in the tri-flange tips on the TF10's
Anyhow, my vote, at least for the time being, goes to the 700s :)
