Loud and clear, something new you should try once
A lot louder than the rotosound or elixer. Took an extra few days to get used to, they're cobalt so something new that's going to need breaking in longer. I would probably go back to elixer for smoothness and ease of play . They're a bit tougher to play but they're definitely worth a try.

Hands down, the best strings I've ever used
I've tried every brand of string, known to man and settled on Ernie Ball Slinkys for years. I tried some Cobalt strings a year ago and haven't used anything else since. They're even better than Slinkys. I prefer the feel of the wound strings. The wound strings sound a bit fuller and whilst marginal, they seem to last a bit longer. The unwound strings are the same as you get in Slinkys. Well worth the extra £2 or so.

Bright and loud
I’m not too experienced in choosing new guitar strings but I thought I’d give these a go. They are really bright and loud and i definitely can hear and feel a difference. I took a risk and used them on stage at a gig and they performed perfectly and I didn’t even need to ‘break them in’. I tend to play lots of genres but more focused on metal and these strings are perfect. Definitely recommend them 👍.

Slinky Cobalt Strings
Best sounding strings I've used for a long time. Not sure how long they will last till they maybe dull in tone since I only put them on last week but so far really great.

They sound nice.
I have an Epiphone Wildkat, a Les Paul shaped semihollow guitar fitted with a pair of p90 pickups and a Bigsby. After I'd put these strings on there was a very noticeable difference in the acoustic tone, quite a bit brighter, less dead sounding and louder. Electrically it sounded different too. Fuller and with a little more agressive snarl when driven. I like the sound and feel of this set and will probably replace them with the same when needed.

Great strings
As someone who usually uses 9 gauge I wanted something a little thicker but not 10’s as they hurt my hands. These are a perfect in between and stay in tune much better. Don’t listen to the reviews about black stuff coming off on your hands haven’t had any issues. Sound great and feel great
