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 Irons

They interact with the turf really well, fairway finders, keeping them!

Great Looking Irons

Looking down at address they look like callaways best iron ever, the big Bertha. Doesn’t get any more inspiring than that.

Great Game Improvement Irons

The larger face makes ball striking a lot easier, and less intimidating on the course, would revommend to anyone getting into the game.

Well Worth The Wait !!!

I waited to purchase and I’m so glad I did. Great irons and hit so accurate. Love them !! Replaced my AI HL smoke irons.

High Handicap Heaven

Very good looking, great feel and extremely forgiving. 3 rd time addition to the game, after taking long breaks due to life and frustration, I found these clubs to live up to the marketing hype that is generally words used to sell clubs.

The Best Ever!

Absolutely the easiest clubs to hit! I play one handed due to an injury, I’ve been playing for over 30 years! I’ve had all kinds of clubs and these are the best! My swing speed is mid/high 60s - I had convinced myself I needed senior flex graphite shafts, but then I discovered the regular flex steel works better! The max OS irons are incredibly forgiving and so easy to hit! Go check them out, you’ll be amazed!

Great Clubs

Straightest hitting clubs I have ever hit. Solid hitting irons.

So Easy To Hit Solidly

These babies really have great turf interactions. The redesigned sole really helps make it so forgiving. I don't know if it's because I'm hitting the ball more solidly, but I feel like I'm getting 5-7 more yards than with my old Callaway iron.

Improved Consistency And Distance Control

It’s early in the season here in New England but I have been able to get in four rounds since I received my new irons a few weeks ago. I am already noticing more consistency with the longer ones 4,5, and 6 irons) and better distance control with the shorter ones. A few people have asked what I am hitting and when I tell them the Quantum Max OS they immediately compare the size of the club face with their own. None have asked if they can try using it for a shot or 2 but I can see that happening soon, especially if they struggle with their own.

Quantum Os Irons

I recently traded in my elyte high launch for the new quantum oversize and think I made the right choice. Still low single digit but pushing 70 so have lost lots of speed. These irons definitely are easy to hit and stop very well and right now our greens are extremely hard due to no rain. While I don't love the thicker top line looking down they square up to the target by themselves.

Irons

Love them. I’ve been playing Rogue X irons for 11 years The improvement is unbelievable. Hitting them a lot higher and half a club longer. Thanks

Quantum Irons

My transaction went very smoothly and I am enjoying my new Quantum irons.

Love Them And Look Nice

Upgraded from an old set of Calloway’s that were rifle extra stiff. I am older now and decided to move to these. They are easy to hit very forgiving and I just love the irons. They go straight and hit a long way.

Best Irons I Have Ever Owned!

Traded up from Mavrik max irons and very happy I did. Biggest difference in irons I have ever seen! These go where you point them. Irons have always been the weakest parts of my game and these have made a big difference. Hitting more greens and they instill confidence to just swing and let the club do the work. Well worth the investment in my game!

New Clubs!

I could not get into a custom fitting, so I made the decision to go ahead and get them by myself, and I've only had a chance to play one round. They feel good and the extra length is great as I'm 6'1" and I fell this length keeps my body more in line with the ball.
