  • Ping i525 irons vs Ping i59 irons Comparison

This is our comparison of the Ping i525 irons vs Ping i59 irons

I'm an avid golfer, a 9.2 handicap on my way to a 2 (been a 5.6) and frequent tester of golf clubs and equipment since 2015.

I tested the Ping i59 and i525 irons on the range using my Swing Caddie launch monitor over the course of 3 days. I didn't have my best stuff, but I hit a number of good shots with both iron sets. I figure I hit about 6 buckets of balls between the two sets. 

Summary: The i525s are 1/2 club (wedge & short irons) to a club (mid & long irons) longer than the i59s. Feel & sound are similar, as well as trajectory. The i525s are more forgiving on minor mishits than the i59s.

Let's take a look at what sets these clubs apart. 

Ping i59 irons were released in 2021 and are the company's premium player blade irons. And, they look the part. Compact clubheads. Thin topline and sole. Minimum offset. Legit lofts (not jacked for distance). Though, Ping does offer a "Power Spec Loft" option if you want stronger lofts. 

The Ping i59s look awesome behind the ball and I'm a fan of the mat or flat (not shiny) finish. They are a low single digit handicaps dream.

Ping i525 irons were released this year and are player performance (distance) irons for those of us in the mid to low handicap range. The clubheads are compact, though not as compact as the i59s. The topline and sole are noticeably thicker but not thick. The blade is longer. Again, not by much. They appear to have more grooves (I refuse to count them). And, the offset is near identical for both irons. 

The i525s look great behind the ball (nearly identical to the i59s) and have the same Hydropearl 2.0 finish. 

Ping i59 Features & Benefits

1) AlumiCore Aerospace-grade aluminum insert

  • The AlumiCore insert let Ping move ~30g of material from the center of the clubhead to the toe and shaft tip to increase MOI (to match the Ping i210 irons). This means more forgiveness and allows for flighted trajectory better players prefer. 

2) Micromax face grooves

  • The grooves are cut closer together to allow for an additional 4 grooves to be added to the clubface, which reduces fliers in short irons and preserves spin in long irons

3) Tour-preferred styling

  • Compact clubhead, thin topline and sole, and minimal offset for a streamlined look. 

4) Hydropearl 2.0 finish

  • Repels water for predictable results in wet conditions

Ping i525 Features & Benefits

1) Forged Maraging Steel Face

  • The strength of maraging steel lets Ping use a thinner face which increases face-flex at impact for faster and higher ball launch, while remaining predictable. 

2) Extreme weighting

  • Ping added tungsten weights to the toe and tip of the shaft to allow for increased perimeter weighting for increased MOI.

3) Polymer injected face

  • Ping injects a polymer compound on the back of the clubface to improve sound and feel while not interfering with face deflection. 

4) Micromax face grooves

  • The grooves are cut closer together to allow for an additional 4 grooves to be added to the clubface, which reduces fliers in short irons and preserves spin in long irons

5) Preferred styling

  • Compact clubhead with slightly thicker topline and sole.

Testing the Ping i59 & Ping i525 irons

As mentioned above, I didn't have my best stuff when testing these irons on the range. But, that's how it goes and I hit enough good shots with solid and not-so-solid contact to form my opinions. 

Looks

The 59s and 525s are seriously good looking clubs in the bag. Say what you want,  but golfers like good looking clubs and both of these are that. 

They both frame the ball well and are hard to tell apart at address. Offset is minimal in both sets. 

Distinguishing factors

  • Thicker topline (though not much) in the i525s
  • Slightly larger clubhead (not much) in the i525s
  • Thicker sole in the i525s
  • Iron numeral is bigger, with a different design in the i525s

Verdict

100% personal preference for this one. Better players like compact clubheads and the i59s win that battle. There's not a big difference, but there's a difference. 

Obsessed with thin vs thick topline and sole? I59s are thinner on both counts, so choose accordingly.

I am not obsessed with ultra-thin toplines or soles. I play a combo set from Ben Hogan, which has blades and hollow body irons. I'm used to smaller clubheads and the i59s appeal to me a smidge more. But, I could easily play the i525s.

Sound & Feel

The i59s and i525s sound and feel the same to me. The clubfaces on my Hogans are soft carbon steel, so these felt a harsh in comparison.  

Shaping & Flighting

I hit tight draws all day long. Ball flight for both was medium, to medium high. 

Forgiveness

The nod goes to the i525s. I lost less distance on mishits with the i525s.

Like I mentioned above, I wasn't exactly peppering the sweetspot on either of these irons during my testing. But, when I got close, I got good distance and performance and not as much punishment as I deserved.  

Distance

The i525s have stronger lofts across the board. Less so in the short irons, and up to 3 degrees in the long and mid irons. So, yeah, they are longer than the i59s. 

So, which irons should you buy?

Looking for traditional player irons with traditional specs and looks? Gotta go with the i59s.
