Cobra BiO CELL Irons Review

Cobra BiO CELL Irons ReviewCobra BiO CELL Irons Review

This is a review of the Cobra BiO CELL iron set, a game-improvement iron set said to pack “game-changing technology”.  The BiO CELL line serves as the predecessor to the Fly-Z.

How do these irons perform?  Are they worth the buy?  How do they stack up against other similar offerings in the game-improvement class?  Read on to find the answers.

In a hurry?  Here’s the quick overview and verdict for you…

Rating:  4.7/5 (Excellent)

Pros:  Distances are reliable and repeatable throughout the bag; amount of forgiveness is considerable; many people love the bold and high-tech look; feel is comfortable; price point is competitive

Cons:  Look doesn’t suit traditionalists, some would like some more length, some find the stock steel shaft to be lighter than preferred, strong lofts can result in low trajectories for golfers with slow swing speeds

Classification:  Game-Improvement

Recommended for:  Although any golfer can play BiO CELL irons, they’re most recommended for stronger swingers and high handicaps looking for forgiveness.  Skilled golfers may want something with more workability.

What are the reviews like?

The BiO CELL irons have a very positive reception overall — a 4.7 rating on Amazon with over 22 customer reviews (click to read them) as well as positive verdicts from most reviewers.  People have praised the solid and reliable distance, the great forgiveness (preserves ball speed and direction even on mishits), the cool futuristic look, solid feel and affordable price.  Despite this, these irons don’t appear to suit everyone — some people rather dislike certain attributes like the relatively light weight, longer lengths, strong lofts and more upright lie angles.

What are the features?

The BiO CELL irons, according to Cobra, are packed with “game-changing technology”, which consists of the following:

  • heavy tungsten weights that are strategically positioned in the toe and heel of the long and mid irons for more forgiveness
  • tungsten centered behind the hitting area in the short irons for increased spin control, better feel, flexibility and additional distance
  • a large face that is unsupported through a perimeter undercut — this results in more face flex (twisting ability) and thus more ball speed and distance
  • BiO CELL and E9 Face Technology which allows engineers to have more freedom with weight movement; this, in turn, allows weight to be moved into positions which promote a low center of gravity (CG) and high moment of inertia (MOI) for more distance and forgiveness

The BiO CELL irons are available in four colours — silver, blue, red and orange — as well as two stock shafts — the Cobra BiO CELL graphite and True Temper Dynalite 85 steel.  For full specifications, see the tables below:

How do these irons perform?

Forgiveness:  Although not as forgiving as some other max game-improvement irons, the BiO CELL irons are still quite forgiving.  Both shot dispersion and distance loss on mishits are fairly minimal.  The BiO CELL irons also don’t tend to generate much sidespin, which can be very helpful for golfers who would otherwise fade or draw more than they would like.  Solid strikes on or near the sweet spot are rewarded with a long and straight ball flight, but even mishit shots hold the line and carry acceptably well.

Distance:  The BiO CELL irons are fairly long (results will differ depending on the person), although by no means are they the longest irons out there; those looking for maximum distance with game-improvement irons may want to look into other options.  However, carries and distances are very consistent/repeatable throughout the bag.  As mentioned above, mishit shots still retain a very solid ball speed and distance.

Playability/Trajectory:  The BiO CELL irons have relatively strong lofts compared to other game-improvement irons, but in spite of this, long irons are still pretty easy to get up in the air.  The irons are workable to an extent, with baby draws and fades quite easy to achieve.  They also do well around the green and out of trouble lies like the rough or sand.

What about look, sound and feel?

Look:  The clubhead has a “futuristic”, bold cavity design with a black/white/(third colour — see features section above) colour scheme; I personally think it looks great, but I suspect there are people out there who think there’s too much going on.  The thickness of the topline, offset and blade size are about what you would expect for a game-improvement iron.  Overall, it’s a pretty sweet package that addresses the ball well and inspires confidence.

Sound and Feel:  Two of the best attributes of these irons.  They feel light yet smooth and stable through the ball, and the impact sound can be characterized as a solid, muted “thud” — very satisfying, but nothing earth-shattering.  Impact vibrations are also minimal.

Where should I buy these irons?

The manufacturing of new BiO CELL irons has been discontinued by Cobra.  These days, I would argue that the best place to find BiO CELL irons online (new and used) in all different set, shaft flex and type configurations at fantastic prices is eBay.  Rest assured that you’re completely protected by eBay’s Money Back Guarantee.

I would recommend buying irons with a shaft type and flex that you believe best suits your swing — in general, the faster your swing speed, the stiffer your shaft should be.

What about a used set?

If you would rather save some money and get a used set of BiO CELL irons, try eBay or Global Golf.  You can find some pretty awesome deals in these places.


The Cobra BiO CELL irons don’t really have any glaring weaknesses.  They do a great job of addressing the needs of low, mid and high handicap golfers, although those who are at the professional level may want something with more workability.  The best thing to do is try them out for yourself and discover if they are or aren’t for you.
