FIiO FF1


Key Features:

High-Performance 14.2mm Dynamic Driver
- Beryllium-Plated PU Diaphragm: Utilizes a high-rigidity, lightweight beryllium-plated polyurethane diaphragm for reduced distortion and improved transient response.
- Hidden Bass Duct: Incorporates a concealed acoustic resistance pipe in the ear stem to extend bass response and reduce cavity resonance, achieving low frequencies as low as 38Hz.
- Long-Throw Design: Implements a scientific long-throw design for a lower resonance frequency, resulting in deeper bass and a wider soundstage.

Open-Back Design and Lightweight Comfort
- Open-Back Soundstage: Features a diffuse open design for a speaker-like, spacious soundstage and natural listening experience without complete isolation.
- Ultra-Lightweight Build: Weighs only 3.2g per earpiece with a compact 16.2mm diameter shell for a comfortable, near-weightless feel during extended use.
- Side-Sleeping Friendly: Low-profile design does not protrude from the ear, making it comfortable for side-sleeping while listening.
