How it plays
0–100 editorial ratings compiled by Tennistory from specs and published reviews, not lab measurements.
Feel
An absurdly large sweet spot — mishits still make it over, and power comes cheap.
Background
The Ai generation is where EZONE broke through: black-and-yellow paint, and an Isometric head stretching the effective hitting area as far as it goes.
Successor: Yonex EZONE 100 (2025)
