Charm cello strings have an intense, rich & focused sound; very responsive with excellence projection. The set offers a winning combination of solid steel core & rope core strings at a great price!
Steel core cello string set: Item: CH300
A alloy/steel core, D alloy/steel core, G chrome/rope core, C tungsten/rope core
They're not at the top of the class, but they're in the class.
Factoring in the low price, I must give these strings five stars. If they cost $275... well, I'd still give them four.
My favorite string combination is C&G Thomastik tungsten Spirocore + D&A Jargars. This due to their focus and response.
My second favorite is Thomastik Versums. This due to their warmth and ease to play.
The For-Tune Charm set? The others soundly out-score it, but they don't out-class it. The Thomastik team scored many more runs, but the Charms were still in the ballpark.
The set I got are to be compared more with the Versums than the Spirocores. VERY easy to play, intonation is even across the strings, and the sound is more warm than focused. The tone colors were very simple and slightly harsh compared to the Versums' rich and layered sound, though.
I put it on a cello that had Thomastic Präzisions on it before. It was definitely a step up, particularly in responsiveness. Even the C string starts right up. The bow seems to glide over the strings. And while they aren't particularly focused, they were more so than the Präzisions. I didn't like the Präzisions to start with. If you do, you might disagree.
If your cello is naturally muddy and muffled, look for strings with more focus to counterbalance, because these aren't for you. Looking for a warm sound, but can't justify $300 for Versums? These are recommended.
