H Hifihear KZ ZSN PRO X
Score: 84/100
FiiO FF1
Score: 65/100Rankings
The KZ ZSN PRO X offers audiophile-level detail with a hybrid driver setup, solid metal build and a secure fit at a budget price. It lacks active noise cancellation and a built-in mic, and the proprietary cable connector may be inconvenient for some users.
The FiiO FF1 is an entry-level wired earbud with a large 14.2 mm driver, high sensitivity, and a generous accessory bundle. While comfortable and easy to drive, its bass is modest and the semi-proprietary connector may limit upgrades.
