To summarize,
-Strong reaction to the magnets in pickups
-Stay in tune very well (for me at least)
-Sharp, clear tone
-Each string is distinguishable from another
-Durable
-Silky smooth
If you have any questions, shoot a comment if you want, but I am telling you, I would not hesitate to try these strings at least once.
I have them on my G&L ASAT, which is set up to play traditional jazz---clean and warm tone from a neck pickup. I play this in a guitar duo so we trade playing melodies/solos and comping duties. I've never really been able to get used to flats, which lack that tactile response and fretting hand finger bite that rounds give so I was looking for strings that gave good jazz tone and had that "authority" in the bass without flats. Most users of these strings will likely want to play downtuned metal, but they make fine jazz strings, too.
For reference I have a Seymour Duncan Seth Lover in the neck slot and the guitar is tuned to E with low action, so there's a lot of string tension. By rolling tone I get a good jazz sound in a clean amp, and the heaviness of the strings along with some tweaks to the setup give a really rich tone for walking bass lines and shell or "Ed Bickert" type chords, exactly the kind of comping that gets out of the soloist's way and really keeps the groove alive. I think I'd like a wound G a little bit better, but it's not a huge deal. I wish I had a 7 string for those extra low notes for walking bass!
The only thing a little strange about cobalts is that they feel... oddly rough. Slightly corroded, I guess. They're not but they feel that way so you need to realize that that's what they feel like before you think you got a skunked pack.
UPDATE: The "slightly rough" feel I mentioned, or what someone else called "cat tongue feel" has really driven me nuts. I like the tone but I can't deal with the feel, which is just too grippy. I'm going to switch to something else soon.

String tension is a tad higher than the original. So you should have your guitar setup redone as it's going to mess with your neck relief and intonation.
I ran into problems with 2 .009 stings (which broke instantly) and Ernie Balls were quick to help me and replace them free of charge. Great service!!!
I am happy with these stings and I don't plan to go back to the originals.
