Got the HF5s in and I've been running them through the paces. I'm seriously impressed. I find them pretty comfortable with the tips that came on them. These are extremely precise and accurate, and I don't find the bass to be lacking, rather very true to the music. I love the slight coldness to them, but it's not desolate sounding, there's still a tinge of warmth that's balancing. I'm going to run these in some more, but I really dig these so far. The balance of the treble, mids, and lows is superb.
I'm calling these my Samurais. They cut through music like a freakin' Katana.
P.S. These are also a great way to clean your ears.
