Description
The Callaway Quantum Max OS irons are built to deliver maximum forgiveness, powerful ball speed, and consistent carry—wrapped in an oversized, confidence-inspiring design. Engineered for golfers who want help launching the ball higher and striking it more solidly across the face, Quantum Max OS blends modern game-improvement technology with premium feel and performance.
Featuring advanced face architecture, extreme perimeter weighting, and refined sole geometry, these irons are designed to perform consistently throughout the set—helping golfers hit longer, straighter shots with greater confidence.
Key Technologies & Benefits
Modern 360° Undercut Cavity
A two-piece cavity-back design with a fully exposed undercut promotes faster ball speeds, higher launch, and increased forgiveness across the entire face. Extreme perimeter weighting adds stability on off-centre strikes.
Next Generation AI-Optimized Face
Callaway’s AI-designed face architecture enhances ball speed while delivering more consistent launch, spin, and dispersion by matching real-world impact patterns and expanding the effective sweet spot.
Progressive Tri-Sole Design
Reengineered sole geometry changes throughout the set to promote cleaner turf interaction, improved speed retention, and more consistent contact—from long irons through wedges.
Urethane Microspheres
Strategically placed microspheres absorb unwanted vibration, improving sound and feel at impact for a softer, more forged-like sensation in a high-speed, game-improvement iron.
Oversized, Confidence-Inspiring Shape
Designed for high launch and maximum forgiveness, the oversized head profile inspires confidence at address and helps golfers deliver more consistent results.
