Srixon ZXi4 Irons Review

Quick answer

We’d buy the Srixon ZXi4 irons for a mid-to-high handicap who wants speed and forgiveness without an oversized cavity-back look. The hollow head, long blade, and 28.5-degree 7-iron are built for distance. Skip them if you want a dense forged feel, or if the cheaper ZXiR already solves the miss.

Who it’s for

Srixon positions the ZXi4 as a hollow iron with a clean address look, a moderate sole, the longest blade in this design family, and the highest offset. We’d put it in the bag of a golfer from about a 12 handicap into the mid-20s who is losing shots to thin contact and low ball flight, and who still cares what the club looks like.

Swing speed can be moderate to fast. A very slow swing that cannot launch a stronger loft should look at the ZXiR HL instead. The miss this head helps is an off-center strike that still needs ball speed. Budget is $1,499.99 for the set, with single irons from $199.99. That is about $300 more than the ZXiR and about $100 less than the ZXi5.

What we like

The hollow construction is the speed story, and Srixon does not hide it. MainFrame milling on the back of the face saves weight, raises MOI, and is there to hold ball speed when you miss the middle. Our read of the evidence: this is one of the better-looking distance irons, because the help is in the sole width, blade length, and offset rather than a bulky topline.

Feel is better than the last ZX4, on Srixon’s own account. The body uses a softer SUS17-47 material, which also makes loft and lie easier to adjust at a fitting. That is a real buying detail. A hollow iron you cannot bend is a worse fit than a slightly less soft one you can. It will still not feel as dense as the forged ZXi5 or ZXi7. We would not sell it as that.

The Tour V.T. Sole — widths, bounce, and notches — is meant to keep the longer blade moving through fairway, rough, and sand. Progressive grooves run wider in the 4- through 7-iron and deeper from the 8-iron down. That is the right split for a set whose long irons are distance clubs and whose short irons still have to hold a green.

It also combo-sets. Srixon suggests a custom build with ZXi4 in the long irons and ZXi5 in the short irons when you want speed up top and a more compact head where scoring matters. That is a better plan than forcing the hollow head to be your pitching wedge if you do not like the flight.

What we’d change

Srixon lists this as the 2025 ZXi4. It was not part of the later players-iron refresh. The club is still on the official page and still the right head for this job. Just do not assume “ZXi” means the newest forging in the family.

Strong lofts will change your gaps. A 28.5-degree 7-iron and a 43-degree pitching wedge can fly higher and farther than the clubs they replace. The complaint we kept seeing from long-term owners of hollow distance irons is surprise carry, not a lack of it. Map the wedges before you retire the old set.

Workability is limited. Highest offset and the longest blade are forgiveness features. They are not features if you want to flight a knockdown or hold the face open. We’d pick the ZXi5 or ZXi7 for that.

Feel remains the ceiling. Good for a hollow iron is not the same as a forged cavity. If the sound on a thin strike bothers you in a fitting, believe the fitting.

Stock steel is KBS Tour Lite, a high-launch shaft. Srixon also lists a KBS TGI graphite option on the product page. The stock grip is a Golf Pride Tour Velvet 360. Right- and left-hand heads are available. The sand wedge is right-hand only.

How it compares

The ZXiR is the value game-improvement pick at $1,199.99. It is a cavity back in i-ALLOY, not a hollow players-looking head. We’d pick the ZXiR for most higher handicaps and the ZXi4 when the address look is part of the decision. See ZXi4 vs ZXiR.

The ZXi5+ is the forged distance alternative, about $100 more, with a 29.5-degree 7-iron. We’d pick the plus model if you want Endo-forged feel. We’d pick the ZXi4 if the hollow head’s speed and offset are what the miss needs.

The Cobra KING TEC X is another hollow players-distance iron, currently $999 in the catalog against this $1,499.99 set. We’d cross-shop it if price is the objection and you still want a tidy head. More context is in our best irons for high handicappers and best Srixon irons guides.

Should you buy it?

Buy it if you have seen it next to the ZXiR and you are willing to pay about $300 for the sleeker hollow head. Get the lofts checked against your wedges, then check today’s price at Srixon above. If you only need forgiveness and a softer feel, buy the ZXiR and keep the difference.
