EPON EF-02D Driver

Test Review: EPON EF-02D Driver – A Sophisticated, High-Performance Forgiving Driver

I recently had the opportunity to test the **EPON EF-02D Driver**, one of the most talked-about golf clubs among enthusiasts.

The shaft is the DEAD OR ALIVE ZEN Z55.

It features a 10.5° loft, a length of 44.75 inches, a shaft weight of 55g, a D2 swing weight, torque of 4.5, a mid kick point, and an overall club weight of 307g.

This is a bold new design from EPON, unlike anything they’ve released before.

While it was surprising at first, I quickly came to admire the aesthetics and premium finish—true to EPON’s high standards.

The all-black head exudes a sleek, mature vibe.

There’s an undeniable luxury and sophistication that sparks a sense of pride in ownership.

I was captivated by the beautifully crafted sole.

The finish is meticulous with no visible flaws. A black sole is a rare sight in EPON’s lineup.

Its shallow, large-sized head aligns with modern design trends.

Even from this angle, its elegance is striking.

A large groove on the sole is a rare and possibly first-time feature from EPON.

Both the width and depth of the groove are significant.

Though many manufacturers have moved away from grooves, EPON’s inclusion suggests purposeful innovation.

Toe side

Heel side

Four small weights are placed on both the toe and heel, making a strong visual statement.

There are no engraved numbers, so their weight remains unknown. They don’t appear to be interchangeable.

The neck length is standard.

The neck includes an adjustable hosel system.

I tested the driver in the “1” position.

Position “3”

Position “5”

And also “7” were available.

Odd-number settings only? Possibly there are intermediary settings as well.

The driver has a standard shallow profile.

I’d call it a “beautiful shallow.” EPON combines elegance and aggressiveness perfectly here—deep black, refined edges, and an inviting but bold shape.

Though I normally prefer a slightly thicker profile, this one is irresistibly appealing.

Great looking face.

I expected a more futuristic look due to its functionality, but was pleasantly surprised.

Though shallow, it doesn’t feel exaggerated or quirky. It’s well-balanced and welcoming even for players who dislike unconventional designs.

The carbon composite crown was a real surprise—possibly a first for EPON.

Though I’m not personally a fan of carbon, I have fond memories of PRGR’s TR DUO, which also pioneered this trend.

A well-made carbon head offers a rare combo of aesthetics and distance.

Carbon can sometimes look cheap if done poorly, but this one is clean and uniform.

Even the crown mark is rare for EPON. Personally, I prefer no alignment marks, but if there is one, I’d like it to be distinctive—perhaps EPON’s “e” logo?

Toe side

Heel side

There are white lines on both the toe and heel of the crown—a common visual aid, though I find them unnecessary.

The face texture is clean and solid.

Unlike many cheap-looking faces, this one is refined and feels like high-quality glass—clear and smooth.

It features proper grooved scorelines, not just cosmetic lines like some modern FF (Flat Face) designs.

Taking a few practice swings, I found the feel to be light and responsive, yet stable in motion.

This shaft might be the perfect match for the head, but I’d love to test other shaft options too.

This shaft is named “ZEN,” which adds an extra layer of Japanese flair.

The “Made in Japan by EPON” label adds to the sense of quality.

If possible, I always prefer both head and shaft to be made in Japan.

At address, the look is quite natural.

Not exactly “unusual,” but it does have a draw-biased appearance.

Its shallow profile gives the impression of a high-draw trajectory.

While I perceived it as draw-biased, others might find it neutral—it depends on your definition of “neutral,” which has evolved over the years.

The carbon crown is prominent but not distracting. It didn’t interfere with my setup at all.

Among the many carbon composite drivers I’ve tested, only this EPON and BALDO struck me as visually beautiful.

Let’s get into the actual hitting impressions.

The feel at impact is excellent.

It’s not soft, but firm without being harsh—a well-balanced sensation that lets you “feel” the ball.

This is one of those cases where face texture and feel actually correlate.

With its refined, appealing feedback, it’s easy to appreciate why EPON emphasizes feel across its lineup.

The crisp-yet-forgiving response may be what “experiencing titanium” is all about.

Titanium has been used in drivers for over two decades, but there’s a wide range of quality. Some make you wonder if it’s really titanium at all—this one absolutely is.

Though carbon heads are trending, I believe titanium will remain a strong contender for years to come.

The sound is also outstanding.

I’d call it “superb”—pleasing and confidence-inspiring.

With all its adjustability and modern features, I expected compromises in feel and acoustics—but not here.

Aside from EPON’s AF-106, I haven’t heard such an enjoyable sound from any recent driver.

It’s not quiet—it’s a slightly louder, crisp pop that brings satisfaction with every swing.

Despite the volume, it never felt too loud or jarring, and I was able to swing freely every time.

The ball launches very easily.

While the black color might suggest a “hardcore” club, the shallow design makes it surprisingly friendly.

This driver feels very different from the shallow-faced GTD driver I tested previously.

It caters to both hitters and swingers alike.

Stability is high—it’s clearly an automatic-type driver.

As expected from its setup, the ball easily draws and avoids leaking to the right.

I had initial doubts about the shaft, but it performed well—no signs of “giving up” or causing mishits.

You can tell EPON invested heavily in R&D for both the head and the shaft.

I wonder if the shaft is made by a third-party OEM or by EPON themselves?

This is a great option for slicers, but it’s not a miracle cure for slices—it still requires good technique.

This driver delivers impressive distance.

Among today’s forgiving drivers, it ranks near the top.

High-launching, strong trajectory, and long carry define its performance.

While the adjustable weights, grooves, and hosel draw attention, the head’s raw performance should not be overlooked.

In terms of workability, this driver is more automatic than responsive.

I tried to curve the ball slightly to the right—it worked, but not dramatically.

A more reactive head would help if you want to shape shots consistently.

Here, the “dull” response actually prevents over-manipulation, which may reduce big mistakes.

As a natural hook player, I found it easier to hit left than right.

With modern club design reducing the need for players to manipulate the ball, clubs like this help simplify the game.

Post-Round Impressions

Unlike many automatic drivers, this one doesn’t feel awkward at address or off-balance—and it’s far from boring.

Modern adjustability often shifts the center of gravity, making some drivers feel off. That wasn’t the case here.

Some clubs look great but have CG issues that affect feel and performance. This EPON felt perfectly centered.

Not all clubs hit clean from the middle anymore—some are designed to strike off-center, which can lead to misinterpretation and disappointment.

The more complex clubs become, the harder it is to pinpoint performance issues.

Is it because it’s EPON?

I truly hope more manufacturers adopt this level of quality and refinement.

Some brands release sloppy, uninspiring clubs—that’s always disappointing.

Performance aside, appearance matters. Golfers want to enjoy their gear visually too.

Expensive doesn’t always mean luxurious or well-crafted.

I’ve tested many costly clubs that lacked both performance and quality.

Conversely, there are budget-friendly clubs that outperform expectations in both areas.

Many overseas-made clubs used to be cheaper, but now prices are comparable to Japanese models. So why not choose domestic craftsmanship?

The only advantage of overseas production is price—nothing more.

What makes this driver truly special is that it blends the latest technologies—weights, carbon composite, grooves—with uncompromised feel.

Add in the adjustable hosel, and this becomes an extremely attractive option for modern golfers.

If you’re looking for forgiveness, launch, direction stability—and you don’t want to sacrifice feel—this club is a fantastic choice.

More golfers should experience the ease of use and superior feedback this driver offers.

Testing EPON clubs always feels like a treat—and this time was no exception.

The EF-02D’s friendly nature, feel, and sound made it a joy to test.

This is a driver I’d love to try again and again. It’s simply that good.
