Callaway Quantum Max OS Irons

About This Item

Quantum Max OS blends confidence with maximum forgiveness, powerful speed, and consistent carry—all in an oversized shape designed to help golfers hit it more solid across the face.


Modern 360° Undercut

  • The Modern 360° Undercut Cavity is designed to deliver faster ball speeds, higher launch, and more forgiveness across the face, thanks to its advanced two-piece design with extreme perimeter weighting and a fully exposed undercut for added flex where golfers need it most.

Progressive Tri-Sole Design

  • The Progressive Tri-Sole Design promotes cleaner, more consistent contact across the set, with a reengineered sole geometry that adapts from long irons to wedges for smooth turf interaction and efficient speed retention—even on heavy strikes

Next Generation Ai-Optimized Face Design

  • The Next Generation AI-Optimized Face delivers faster ball speeds and more consistent launch, spin, and dispersion by intelligently shaping the face to match real-world impact patterns and expand the sweet spot.

Urethane Microspheres

  • Urethane Microspheres enhance sound and feel at impact by absorbing unwanted vibration, delivering a softer, forged-like sensation in a high-speed game-improvement head.

Oversized, Confidence-Inspiring Shape

  • Quantum Max OS is built for higher launch and maximum forgiveness—all in an oversized shape that inspires confidence at address.

Quantum Os Irons Work Well For Me

Go well with my set of quantum os irons. As with the other irons I have to get use to the added distance .

Great Irons!

Great irons. Really enjoying the quantums after playing with Rouge irons for years, which are also great irons.

Great Look. Forgiving.

I am so glad that I made the choice to upgrade to the Quantum Max OS irons. I was hitting the Paradym X irons. They were great irons but the Max OS are better as being more forgiving. I am a 10 handicap at age 67. Some days I hit a little off the center and really don't see any distance loss. In fact I have gained about 5 yards with these irons and I am loving them. They are a very nice club to look at which I feel is a important factor in buying clubs.

Quantum Max Os Irons

I bought them two weeks ago. They are very forgiving and very straight. They are easier to hit and longer then my QI HL irons. I am very happy with the purchase

Max Out!!

I was fitted for the Quantum Max OS during a scheduled session at my golf course. I must say I Loved my Callaway XR irons, but the launch angle and consistency was unmatched with the Quantum Max OS.

Awesomeness At Your Hands!

I upgraded my Rogue ST Max these Quantum irons. The Quantums have a bigger face than the Rogue. I’m very pleased with how they turned out and the look of them. I’m still working on the distances but so far they get the job done.
