Powerful Sound With Newly Developed Dynamic Driver Unit:-

FiiO FF5 breaks the limitations of earbuds with a powerful 14.2mm newly-developed dynamic driver unit. This driver adopts a specially-developed carbon-based composite diaphragm that is paired with PU Gasket Suspension. It’s both lightweight and rigid, delivering powerful sound with quick transients, extended lower and higher-end frequencies, and minimizing non-linear distortion in the output signal. The pair has been tuned to deliver lovely vocals, especially rich and lush sounding female vocals.

Professionally Designed Open-Back Cavity Design:-

FiiO development team aimed to reduce the unwanted reflections and vibrations within the shell of the FF5. They have carefully designed the cavity structure with a diffuse open back cavity design. It allows for cleaner, purer sound with improved bass and a wider sound field. 

Extended Bass Acoustic Resistance Pipe Design:-

In order to maintain a clean bass response with the FF5, FiiO has designed the pair with acoustic resistance pipes that helps to effectively increase and extend the bass response. When the diaphragm vibrates, the air pressure is diverted towards these acoustic resistance pipes reducing the resonance in the lower end and delivering a clean response.

Rich & Seductive Sound Tuning:-

FiiO FF5 is tuned to deliver rich vocals and impressive details with a powerful lower end in a single package. The pair has been adjusted to deliver clear, crisp vocals and accurate instrument details.

Attractive Design With Lightweight Aesthetics:-

FiiO FF5 is a premium earbud designed with CNC-machined aluminum alloy ear cavities. Each earphone weighs just only 3.4 grams maintaining a lightweight with a solid, robust build. With its ergonomic shape and lightweight design, the FF5 simply disappears in your ear!! FiiO also bundles six pairs of silicone rings for a comfortable wearing experience.

High-Purity Silver-Plated Monocrystalline Copper Cable:-

FiiO FF5 comes standard with a high-quality silver-plated monocrystalline copper cable. It has a 4-strand configuration with 392 wire cores in total. It has expanded MMCX connectors and swappable termination plugs. The package includes 3.5mm and 4.4mm termination plugs.

Nice unit
Using this for deterring my hot rod being stolen. Good price for this. Installation was no surprises and just let them try to steal my hot rod now. First one that was ordered arrived damaged, went through the process of getting a replacement which was simple and received the replacement in a couple of days.

Failed after 2 months
Failed after about 2 months of being used as a battery isolator. When activated, only passes about 2 volts though the contacts on a 12 volt circuit now. Wasted my time and money.
