Overview
Phosphor bronze wrap wire is wound over a hexagonal high-carbon steel core in these D'Addario Flat Tops, then precision ground and polished. The result is a smoother string surface than a plain round-wound set.
A warm, semi-bright voice with a smooth feel and less string noise is the reason to look at it. The wrap is described as balanced and warm enough for all genres. Coating is not mentioned, and the gauge appears only in the title.
Who it's for
Guitarists who play in many genres and want warm tone with less finger squeak under the hand. Players after an extended-life coating should look at a coated line instead.

Performance notes
A precision grinding step removes the raised ridges of a round-wound string, which cuts finger noise and smooths the feel. The hexagonal core grips the wrap, and phosphor bronze supplies the warm, semi-bright voice. Tuning stability is claimed by the listing but not quantified.
