What makes these Ernie Ball strings "Flatwound" and how does that affect the sound?

Flatwound strings feature a smooth, flat outer winding, providing a distinct playing feel compared to roundwound strings, significantly reducing finger noise and fret wear. However, these Ernie Ball Cobalt Flatwound strings uniquely combine this smooth feel with the power of Cobalt. Sonically, they deliver higher output, beefy yet defined lows, improved midrange focus, and a brighter sound with growl, blending the best characteristics of flats and rounds for a versatile and articulate tone.
