FiiO JH13
FiiO is expanding its in-ear headphone range with the JH13, a hybrid model aimed at users who want to try a more advanced driver configuration without spending very much. According to the manufacturer, these IEMs are intended to combine technology associated with more expensive designs with straightforward usability and easy drivability from typical mobile sources. At the centre of the JH13 is a three-driver hybrid layout consisting of a 10mm dynamic driver for the low end and a pair of balanced armature drivers handling the upper registers. A specially designed crossover is meant to integrate both sections smoothly, avoiding the disjointed character that can sometimes affect entry-level hybrids and delivering a clearer, more layered presentation than a typical single dynamic driver design.
The dynamic driver uses an asymmetric inner-and-outer dual magnetic circuit developed with the help of finite element analysis. The idea here is to increase magnetic flux density in the voice-coil gap, which should improve efficiency and diaphragm control during rapid signal changes, including demanding percussive passages. With a rated sensitivity of 110 dB/mW and an impedance of 24 ohms, the JH13 should be easy to drive from smartphones, simple DAC dongles and laptops, while still leaving room for audible gains from a better portable player or dedicated DAC/amp.
The dynamic driver is powered by a Japanese-made Daikoku CCAW voice coil, using copper-clad aluminium wire to reduce moving mass. In practical terms, that lighter assembly is intended to improve transient response and decay behaviour, which should help with bass definition, the attack of percussion instruments and overall treble clarity. FiiO has also included a pressure-relief system for the driver chamber, designed to reduce the discomfort that can build up in the ear canal during longer listening sessions.
The faceplates are made from genuine zebrawood and covered with a transparent protective layer, so each pair has a slightly different grain pattern. That choice serves not only an aesthetic function but also a structural one, as the rigid material is intended to help suppress unwanted resonances. The main shell is semi-transparent and lightweight, and the low mass of each earpiece, combined with over-ear cable routing, is meant to support a secure and comfortable fit. The JH13 also carries Hi-Res Audio certification, confirming compliance with the bandwidth and performance criteria associated with that standard.
In the box, FiiO includes an oxygen-free copper cable built from 120 strands arranged in four braids. It terminates in a standard 3.5 mm plug and uses 0.78 mm 2-pin connectors, which makes it easier to swap the cable for another one with a different plug or inline controls. The company also points to a construction intended to minimise microphonics, reducing the amount of cable-borne noise transferred to the earpieces while walking or moving around. The FiiO JH13 is now reaching the market in the budget hybrid IEM segment, with current pricing around £29/$39/€39. Info and photos by FiiO.
