Ernie Ball 2721

No Brainer

What can I say, its Ernie Ball. For the money unless you want coated strings these are the standard for me. The Cobalts have such a crisp and powerful sound from top to bottom. I have always relied on Ernie Ball strings and find these are really durable and very rarely break, I play mainly rock and metal so their great punchy sound makes these the set i return to every time.

Very good strings

I use these strings as I have an allergy to nickel and these are safe on my skin. They also happen to sound very good, powerful and have a good lifespan.

The most durable strings

These are my favorite strings so far, great sound, durability and strength. Regular strings Ernie Ball are also good, but their durability does not suit me, since I play mostly downstrings, then my sixth string often breaks, I don’t know why, perhaps the problem is in the angle of the brigade or in the string, but this is not important, the important thing is that cobalt strings are much stronger, louder and have a richer sound, when lowering the tuning to drop A, they sound great on the Gibson scale. I will use these strings as long as I have enough money for them, and if I don’t have money for them, then I will save up, because these are the most metal strings ever !!!

Interesting timbre, darker color than standard.

The sound has become clearer, brighter and louder. Hopefully the statement that cobalt increases string life without sacrificing sound quality is also true. I wonder if there is a function supplement a review? ))

Best Strings

They’re the best strings you can buy. IF you have money - they need to be replaced once a month if you play everyday because they pick up all the grime on your fingers. BUT they sound amazing!

Cobalt is cool.

But that is just my opinion.

Sound great to me, no complaints.

très bon choix pour tous les styles

un compromis parfait pour garder les qualités d'un tirant fort comme la stabilité et la puissance et pour avoir la facilité et la souplesse de jeu des tirants faibles . bon équilibre basse - aigu en haut et en bas du manche.

la couleur du son est bien sur métallique mais assez neutre pour respecter les caractéristiques d'une guitare (et d'un ampli)

Consistently good

Great, consistent sound for Les Paul rock riffing. I trust Ernie Ball strings to deliver consistently.

good strings

good strings with a very different feel

Simply the best strings.

I've played these strings for, I think, over decade now.

Clarity, sustain, tone, longevity all is there. They withstand heavy vibrato use, divebombs or what ever through at them. Some of my guitars are Floyd Rose equipped, some have vintage tremolos, I use Slinky Cobalts on all of them. Nothing sounds as good as them. I'm spoiled.
