Which to choose
The biggest difference is how the ball lands. The Elyte X is a low-spin, distance-first iron that testers often found a club longer than usual, but that low spin can make the longer irons harder to hold on firm greens. The Quantum Max OS launches high, comes down steeply and stops quickly. Its distance is more mixed, though, and it can carry slightly shorter than the standard Quantum Max.
Both are large, forgiving heads with thick toplines and little workability. The OS has slightly more offset (0.19 vs 0.16 inches) and a slightly weaker 7-iron loft (29° vs 28°). Testers are divided on sound for both: the Elyte X ranges from clicky to quiet, while some OS testers call its strike firm, even harsh, and fairly loud.
Choose the Elyte X Irons if…
you're a mid-to-high handicapper who wants maximum distance from a forgiving iron, and you can accept a lower-spinning flight that won't always stop quickly on firm greens.
Choose the Quantum Max OS Irons if…
you're a beginner or high handicapper who struggles to get the ball airborne and wants a steep landing that holds greens, even if that costs a little distance.
Common questions
- Which one goes farther?
- Testers consistently found the Elyte X long, often a club longer than usual. Reports on the Quantum Max OS are mixed: its strong lofts make it long in general, but it can carry slightly shorter than the standard Quantum Max.
- Which holds greens better?
- The Quantum Max OS. It comes down steeply and stops quickly, while the Elyte X's low spin can make the longer irons harder to hold on firm greens.
- Which feels and sounds better?
- Opinions are split on both. The Elyte X is mostly described as solid on centre strikes, with its sound ranging from a little clicky to quiet. Some testers find the Quantum Max OS solid and pleasant, while others call it firm, even harsh, with a fairly loud, high-pitched sound.
