Pros & cons
- A super distance iron - a 7-iron at close to 130 mph ball speed and ~190 yards carry
- A forgiveness machine - up to 100g of tungsten for an extremely high MOI, with bad swings still above a 1.42 smash
- A genuinely excellent Split Sole - it doesn't play as wide as it looks and glides from any lie
- Cleaner-looking than most super game-improvement irons, with a minimalist Titleist cavity
- Possibly the loudest iron on the market - a sharp 'clap' at impact that polarises
- Light, firm feel - sharper and less substantial than the rest of the T-Series
- Very low spin - get fitted so it doesn't cost you control and stopping power, and there is no shot-shaping

Qi Max HLFrequently asked questions
Who is the Titleist T400 best for?
You're a slower-swinging, higher-handicap or senior player who wants maximum distance, height and forgiveness with Titleist build quality - and you don't mind a loud iron.
Who should avoid the Titleist T400?
You want soft feel, a quiet iron, shot-shaping workability, the spin to hold greens with the longs, or a compact players' shape.
What handicap is the Titleist T400 suitable for?
The Titleist T400 scores strongest for high-handicap golfers.
Does the Titleist T400 have a shot bias?
The Titleist T400 is broadly neutral in shot shape (no built-in draw or fade bias), with a high launch and low spin.
How does the Titleist T400 compare to the previous model?
Unchanged from the 2020 T400 - the same super-game-improvement iron carried over into the 2021 T-Series line, with the same hollow body, heavy heel-toe tungsten, Super Thin L-Face and Split Sole. The newer 2021 build is simply judged a year fresher.
