The FiiO JH3 is an in-ear headphone that utilizes two different types of drivers to deliver a voluminous, well-resolved sound. The dynamic driver, with a diameter of 13.6 mm, provides rich, energetic bass and full mids. The two balanced armature drivers produce precise highs with beautiful transparency. The three drivers are optimally tuned to generate a rounded, harmonious sound profile. The pressure equalization system used by FiiO minimizes distortion and allows for particularly fatigue-free listening, even over long periods. The housing is made from a durable aluminum alloy and features a refined wavy pattern design. The included high-quality headphone cable is made of monocrystalline copper and has a 3.5 mm plug, compatible with a variety of portable devices, as well as 0.78 mm 2-pin connectors, allowing for easy cable replacement if needed. A robust transport case and 7 pairs of ear tips in different shapes and sizes are also included.
