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 Purchase

Bought these after reading a review online. Great set of irons. Very forgiving and a little longer that my old set. I would purchase again.

Not For Senior

I sold my Taylormade irons thinking these would be better, sadly they do not improve my game because I do not get as much distance. I think the questions that were asked to fit me with the right clubs missed the mark. I am a senior and the shafts, regular flex, don't seem to give me the best feel. I was hoping to improve my game, but that won't happen with these clubs.

It Was Time For An Upgrade!!!

I moved from 2006 Big Berthas to the Quantum Max complete set and I am very happy with the technology upgrade - I am seeing a 15 yard increase per club so that is a thing I am getting used to - but its a bad problem to have.

Good Customization

I bought a set of irons 2 months ago and just added an A wedge to fill the space between the PW and my 50-degree GW. I liked the ability to customize the clubs - I'm a senior and am losing swing speed, so I had them bent 1 degree stronger; plus mid-size grips and 2 tape wraps. When I swing correctly, I get very good results and usually very good stopping action on the approaches to the greens.

Great Irons. Increased Distance.

I purchased these irons a couple of months ago ago and I am sorry I didn’t do it sooner. I never had confidence in my iron play but now I do. They have a great feel and range. My friend tried mine and then went out a got his own.

Love The Irons

I bought these irons over the summer and they are fantastic. They have the right balance of performance and forgiveness for a 10-handicap golfer.

Tried Them But Was Disappointed

Purchased these clubs seeking distance and forgiveness, but found them disappointing in both cases. Went back to my Elyte Fast irons, they were much better in my opinion.

You Will Not Be Disappointed

A step up from my previous irons. So far they are solid. Beautiful sound at contact and easy to work with. 👍

Solid Performer.

Purchased a little over a month ago. Replaced my old but effective Steelheads. It has taken a bit to get use to subtle differences, going from steel shafts to graphite. Clean lines. I would say more forgiving than the previous set. Love the ball flight.
