Product identity

The Fuji Labs FJ-iPOD-E3223 is a wired earbud with a 15mm driver and a 3.5mm gold-plated connector. It targets listeners who want a simple plug-in solution for portable devices. The twist-to-fit mechanism and asymmetric neck-chain cord aim to keep the earpieces secure during daily movement.

Sustained listening behaviour

A sensitivity of 115db at 1kHz/1V rms means the driver reaches high volume with minimal source power. Total harmonic distortion stays at 0.1 % across the 17Hz-21KHz range, so bass-heavy passages remain clean during long sessions. The 64 ohm input impedance provides a consistent load for most headphone outputs without demanding a dedicated amplifier.

Build and daily use

The 4.1 ft cord uses a neck-chain layout where the left lead is shorter, letting the right side wrap behind the neck for tangle resistance. Gold plating on the 3.5mm plug resists oxidation from repeated insertion. The twist-to-fit bodies and Basswind system PLUS damping are fixed mechanical features that do not rely on replaceable tips or electronic adjustment.

Questions about this item

How much power does the 15mm driver draw when the earbuds run all day?

The 15mm driver has 64 ohm impedance and 115db sensitivity at 1kHz, so it reaches loud volume with very little power from a standard 3.5mm source.

What source device must I already own for the 3.5mm gold-plated connector to work?

Any phone, laptop, tablet or audio player with a standard 3.5mm headphone jack will drive the earbuds directly.

Will the 17Hz-21KHz frequency response still sound balanced through an older 3.5mm jack that has worn contacts?

The gold-plated 3.5mm connector resists oxidation, and the 64 ohm impedance is easy for older outputs to drive, so the full 17Hz-21KHz range remains intact.
