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.

Great Clubs

Well I'm not much of a golfer but i seem to hit these clubs better than my old ones. I'm getting a little bit more distance and I'm getting the ball up in the air a little more.

New Golfer, Great Clubs

I’m new to golf, started in March with used clubs. Then I went all in on Quantum max OS, and really doing great, the feel, the distance and even on off center hits I still get distance

Great Irons

I am a relatively new golfer, and this was my first set of premium band clubs. Immediately noticed a difference. I have a relatively slow swing speed, and they are not only forgiving, but also added 10 to 20 yards per club. Initially bought the 5 thru A, and recently added the G and S wedges.

Very Forgiving For Beginner Golfers!

These are great. I am a new golfer but needed to order a custom set with 2” added because I’m 6’7” and standard clubs obviously weren’t working. These feel great and are very forgiving. I think they’re sharp looking, and while significantly thicker than “blades”, they’re not ridiculous looking. Because they’re slightly heavier, I find them much easier to control throughout my swing, and both the feel and sound upon contact is great. I would highly recommend for any new golfers looking for game improvement irons.
