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 Max Os

Just traded my Stealth irons w/graphite shafts for the NEW Quantum Max OS. Really love the feel and bigger head of the Quantum’s and so far I’ve been clubbing down on my selection so am also hitting these Quantum’s a bit farther. So far I’m very happy with the trade!!

Feel - See Difference

Good solid clubs that I feel more confident with than my Elyte irons.

Quantum Max Os Irons Review

The Quantam Max OS Irons are what I hoped for when I bought them. The heads are a bit heavier, but that is to be expected. However, the improved forgiveness and accuracy is far better than I hoped for so I think it's a fair trade-off. I'm very pleased with their performance.

Great Game Improvement Iron

A little loud on the strike, but overall a solid game improvement iron. I really like the look of them at address and have noticed that even on miss-hits I am more consistent. I was a little skeptical of cavity design compared to the Elytes, but they have grown on me!

Quantum Irons

Best irons I have ever owned. I have been playing golf 50 years. These irons are the best ever.

Great Clubs!!!!

Main purpose of buying these clubs were to take impact off my shoulders at contact. My previous Callaway clubs were getting a little too hvy for my aging body and the graphite shafts fixed that problem. Clubs hit true but will not eliminate complete miss hits. I wanted to clarify that, b/c even my slightly off from center strikes were still fairly straight in the direction I was aimed.
