TheTechLounge posted a review on the Ultimate Ears Super.Fi 4 Sound Isolating Earphones

The super.fi 4's really ended up winning me over because the whole package was spot on for what I look for in a set of headphones. Ultimate Ears nailed the styling for me with an attractive, minimalist design. Comfort is paramount for anyone looking to put some serious hours into his or her phones, and there's definitely a bunch of upside to be found with this set. I loved the soft, supple ear tips, and the low weight encouraged me to pass my Shures on to a new owner. The build quality felt solid throughout, and you get a two-year warranty from Ultimate Ears. The sound quality is very well rounded, easily equaling other phones of this level that I have had experience with. I don't mind dealing with the few issues I found because the super.fi 4's have so much going for them. Ultimate Ears also offers an iPhone-friendly set with an inline mic and control button for about $20 more, which may deal with the cable length issue for some.
